docs(skills): correct gRPC guidance, a .proto is not a spec target

- Remove --mount from two skills: the flag does not exist in the CLI. Local
  paths are mounted writable when passed with -t.
- Document --target-list, --scope-mode, --diff-base, and OpenAPI/Postman
  targets, so agents stop putting spec URLs in --instruction prose.
- Add the application-security-testing skill as the entry point for
  whole-product AppSec requests, routing each asset to the right workflow.
- Drop contractions and Latin abbreviations across the skill prose.

-You can also run Strix on [OpenCode Zen](https://opencode.ai/docs/zen/) credits or an [OpenCode Go](https://opencode.ai/docs/go/) subscription:
-

-#### Connect your own MCP servers
-
-Strix can connect to Model Context Protocol (MCP) servers you list and expose their tools to the agent during a run. Create `~/.strix/mcp-servers.json` with a JSON list of servers. Each entry is either a local `stdio` server that Strix launches as a subprocess, or a remote `http` server:
-
-```json
-[
-  {
-    "name": "local_fs",
-    "transport": "stdio",

-    "auth": { "kind": "bearer", "token": "your-token" },
-    "allowed_tools": ["list_issues"]
-  }
-]
-```
-
-Each server's tools are namespaced by `name` (for example `local_fs_read_file`). Omit `allowed_tools` to expose every tool the server offers, or set it to a list to restrict which tools the agent can call. The file is optional, and a server that fails to connect is skipped without failing the run. You can point Strix at a different file with `STRIX_MCP_CONFIG`.

-title: "MCP Servers"
-description: "Connect your own MCP servers and expose their tools to the agent"
----
-
-Strix can connect to [Model Context Protocol (MCP)](https://modelcontextprotocol.io) servers you list and expose their tools to the agent during a run. Use this to let the agent read how your system is actually built instead of inferring it from the outside.
-
-A few things it pays off for:
-
-- **A database server.** The agent can read the schema and access policies and see tables left readable without them, rather than guessing from responses.
-- **A hosting or infrastructure server.** Deployments, domains and environment variable names tell it what is really running, so it tests what exists instead of what it discovered by crawling.
-- **An issue tracker.** Known and accepted risks stop the agent re-reporting findings you already triaged.
-- **A logging server.** Reading logs lets it confirm an exploit attempt actually landed instead of inferring it from a status code.
-
-## Setup
-
-Create the file `~/.strix/mcp-servers.json`. It holds a JSON list of the servers you want the agent to reach. Each entry is either a local `stdio` server that Strix launches as a subprocess, or a remote `http` server.
-
-Create the directory if it does not exist, then write the file:
-
-```bash
-mkdir -p ~/.strix
-```
-
-Paste the servers you want into `~/.strix/mcp-servers.json`. The example below shows one of each transport: a local filesystem server over `stdio` and a remote GitHub server over `http` with a bearer token:
-
-```json
-[
-  {
-    "name": "local_fs",
-    "transport": "stdio",
-    "command": "npx",
-    "args": ["-y", "@modelcontextprotocol/server-filesystem", "/path/to/project"]
-  },
-  {
-    "name": "github",
-    "transport": "http",
-    "url": "https://api.githubcopilot.com/mcp/",
-    "auth": { "kind": "bearer", "token": "your-token" },
-    "allowed_tools": ["list_issues"]
-  }
-]
-```
-
-Strix reads this file at the start of each run. There is no default file, so no MCP tools are loaded until you create it. Edit `command`, `args`, `url`, and `token` to match your own servers.
-
-## Fields
-
-<ParamField path="name" type="string" required>
-  A short label for the connection. Each server's tools are namespaced by
-  `name` (for example `local_fs_read_file`), so two servers can offer the same
-  tool name without colliding.
-</ParamField>
-
-<ParamField path="transport" type="string">
-  `stdio` for a local subprocess server, or `http` for a remote server.
-</ParamField>
-
-<ParamField path="command" type="string">
-  For `stdio` servers: the executable Strix launches (for example `npx`).
-</ParamField>
-
-<ParamField path="args" type="array">
-  For `stdio` servers: the arguments passed to `command`.
-</ParamField>
-
-<ParamField path="url" type="string">
-  For `http` servers: the server endpoint URL.
-</ParamField>
-
-<ParamField path="auth" type="object">
-  For `http` servers that need a bearer token:
-  `{ "kind": "bearer", "token": "your-token" }`.
-</ParamField>
-
-<ParamField path="allowed_tools" type="array">
-  Restrict which tools the agent can call. Omit it to expose every tool the
-  server offers, or set it to a list of tool names to allow only those. Strix
-  does not decide for you which of a server's tools only read and which change
-  things, so run the server in its own read-only mode if it has one.
-</ParamField>
-
-<ParamField path="notes" type="string">
-  Free-text notes for the agent about what this connection is and how you want
-  it used, for example "Staging analytics database, read-only, prefer aggregate
-  queries." When set, the notes are given to the agent at the start of the run
-  as a description of the connection.
-</ParamField>
-
-## Choosing connections per run
-
-By default every connection in the file is used on each run. To narrow it for a
-single run without editing the file, use either flag (both repeatable):
-
-```bash
-strix --mcp-server github -t ...        # use only the named connection(s)
-strix --mcp-exclude staging-db -t ...   # use everything except the named one(s)
-```
-
-`--mcp-server` keeps only the connections you name; `--mcp-exclude` drops the
-ones you name. Connection names must be unique in the file; if two entries share
-a name, the first is kept and the rest are ignored.
-
-## Pointing at a different file
-
-To read the config from another path instead of `~/.strix/mcp-servers.json`, either pass `--mcp-config <path>` on the command line:
-
-```bash
-strix --mcp-config ./mcp-servers.json -t ...
-```
-
-or set the `STRIX_MCP_CONFIG` environment variable to that path. The flag takes precedence when both are given.
-
-## Startup confirmation
-
-When servers are configured, Strix prints a one-line summary at scan startup, for example `MCP: connected 1 server (14 tools): local_fs`, so you can confirm your servers connected.
-
-## Seeing the calls
-
-Each call the agent makes to one of your servers is shown with its own icon and
-labelled with the connection it went out to, in the terminal and in the run
-viewer (`strix view`), so a call that left Strix for a server you connected is
-easy to pick out of a transcript. The terminal shows the call and its arguments;
-results can be large and arbitrary, so read them in the viewer, which shows a
-preview you can expand.
-
-## Behavior
-
-- The config file is optional. Without it, a run simply gets no MCP tools.
-- A server that fails to connect is skipped and logged, and the run continues without it.
-- A single malformed entry is skipped without blocking the valid ones.

@@ -216,31 +216,10 @@ VALIDATION REQUIREMENTS:
 - Independent verification through subagent
 - Document complete attack chain
 - Keep going until you find something that matters
-- CLOSURE DISCIPLINE: every candidate you open ends in exactly one explicit state — `confirmed` (working PoC, or a complete source→control→sink→impact trace that is reachable), `ruled_out` (you can name the SPECIFIC control, at a location, that runs on every attacker-reachable path before the sink), or `open_proof_gap` (plausible, unconfirmed, and you could NOT name such a control). "I moved on" is not a closure state. Silently dropping an uncertain candidate is mislabelling an `open_proof_gap` as `ruled_out` and is how real bugs get missed.
-- Missing information is NOT proof of safety: no caller found, can't tell if deployed/exposed, couldn't stand up the service, build failed — each is an `open_proof_gap`, never a reason to mark a candidate clean. Difficulty is a reason to defer, not to suppress.
-- COVERAGE: record every surface you assess with `record_coverage` (surface + risk area + outcome + evidence), including the ones that came back clean — a report that only lists findings cannot say what was reviewed and cleared. Use the `needs_follow_up` outcome for anything left in an `open_proof_gap` state, and carry the same items up in `agent_finish(open_items=[...])`. The ledger is shared and mutable: when you resolve a surface another agent left open — or find that a closed one is not — move that entry with `update_coverage` instead of recording a second one for the same surface. The root agent reconciles all of it via `list_coverage` before `finish_scan`.
-- THREAT MODEL: before you start testing, call `get_threat_model` on the target you were pointed at — it is the scan's shared answer to who the attacker is, where the trust boundaries sit, and what counts as critical here, and it is cached per target rather than per scan. Read it instead of re-deriving trust boundaries yourself; where your testing disproves it — a boundary it calls trusted turns out to be attacker-reachable, a role it did not know about, a host or endpoint it never listed — record that with `amend_threat_model` so the agents after you inherit the correction. Amending is not optional politeness: a model nobody corrects turns the first agent's guesses into everyone's assumptions.
-- Before filing any report, run the counterevidence pass: argue the strongest case AGAINST the finding, record what you found in the `counterevidence` field, set `confidence` honestly (a static-only trace you couldn't execute is at best `medium`), and state what evidence would change the severity. See the counterevidence and severity-calibration knowledge above.
 - A vulnerability is ONLY considered reported when a reporting agent uses create_vulnerability_report (or create_dependency_report for known-CVE dependency/supply-chain findings) with full details. Mentions in agent_finish, finish_scan, or generic messages are NOT sufficient
 - Reporting and fixing are ONE step, not two: when source is available, the reporting agent derives the concrete fix and files it INLINE via create_vulnerability_report (`code_locations` with `fix_before`/`fix_after` + `fix_pr_body`) — the report is not complete without it. Do NOT report first and then spawn a separate downstream agent to re-derive and re-apply the same patch; that just re-does the analysis and wastes tokens. (Do not silently patch a finding WITHOUT filing a report — the report, with its embedded fix, is the deliverable.)
 - DEDUPLICATION: The create_vulnerability_report tool uses LLM-based deduplication. If it rejects your report as a duplicate, DO NOT attempt to re-submit the same vulnerability. Accept the rejection and move on to testing other areas. The vulnerability has already been reported by another agent
 - REVIEWING FILED FINDINGS (orchestrator/root agent): use list_reports to see every vulnerability filed so far in this scan (by any agent, root or child) — metadata-first with per-severity counts — and get_report to read one finding in full by its id. These are read-only orchestration tools: the root agent uses them to track coverage, avoid dispatching work on already-covered ground, assemble the finish_scan executive summary, and reason about attack-chaining across confirmed findings. Leaf/specialist agents should NOT call them — just do your assigned testing and file findings. Each entry shows which agent filed it (agent_name), and your own entries are flagged by_you. list_notes/get_note do the same for notes.
-
-STATE & COORDINATION TOOLS (when and how):
-Every one of these tools writes to state the rest of the scan reads. Reaching for the tool is not optional bookkeeping — the agent after you sees your state, not your reasoning, so state you never wrote is context the scan permanently loses.
-- PLAN — `think`: use before any non-trivial or multi-step move to reason through approach, uncertainty, or what to do next. NOT for acknowledgements, summaries, or as filler before a final answer.
-- SKILLS — `load_skill`: the skills matching your task are already inlined below under `<specialized_knowledge>`; `<available_skills>` lists the rest by name. When you are about to test a vuln class, protocol, tool, or framework whose skill is not already inlined, `load_skill` it FIRST and follow it, rather than guessing payloads or tool syntax from memory.
-- TODOS — `create_todo` / `list_todos` / `update_todo` / `mark_todo_done` / `mark_todo_pending` / `delete_todo`: your own working checklist for a multi-step task. Create todos when your task has several distinct steps so nothing is dropped across a long run; mark them done as you finish. This is private working memory — use `notes` for anything another agent needs.
-- NOTES — `create_note` / `list_notes` / `get_note` / `update_note` / `delete_note`: the scan's shared scratchpad, visible to every agent. Write a note for a durable cross-agent fact that is not a finding and not coverage — a working credential set, a discovered endpoint inventory, an enumerated tenant list, a rate-limit quirk the next agent needs. `update_note` to keep a living inventory current; `delete_note` only for something now wrong or superseded. Check `list_notes`/`get_note` before recon work so you build on what is already mapped instead of redoing it.
-- THREAT MODEL — `get_threat_model` / `amend_threat_model` / `save_threat_model`: covered above. `save_threat_model` REPLACES the whole document and clears amendments, so it is for establishing the baseline or folding amendments in (normally root) — to correct part of an existing model, `amend_threat_model` instead.
-- COVERAGE — `record_coverage` / `update_coverage` / `list_coverage`: covered above. One row per surface+risk; correct an existing row with `update_coverage`, never a second `record_coverage`.
-- RESEARCH — `web_search`: pull fresh, target-specific external knowledge — latest bypasses, WAF evasions, DB-/framework-specific syntax, CVE and advisory detail — before falling back to memorized payloads, and refresh payload corpora mid-spray.
-- SPAWN WORK — `create_agent`: delegate a focused subtask to a specialist child (see the multi-agent rules below for when to spawn and how to scope it). Give it the target to model against and what is already known.
-- TRACK CHILDREN — `view_agent_graph`: your live map of every agent and its status. Call it before spawning (to confirm no existing agent already covers the scope) and before finishing (to confirm no child is still running).
-- STEER CHILDREN — `send_message_to_agent`: send a running child new information, a course correction, or a request to wrap up, without killing it. Use it to answer a child's question or narrow its scope mid-run.
-- BLOCK ON CHILDREN — `wait_for_agents`: block until named children report back when your next move genuinely depends on their results. If you can keep making progress in parallel, keep working instead of waiting.
-- CANCEL CHILDREN — `stop_agent`: gracefully cancel a child whose work is redundant, misdirected, or no longer needed. Prefer `send_message_to_agent` to redirect a child that is merely off-track; reserve `stop_agent` for work that should not continue at all.
-- FINISH — subagents call `agent_finish` (with `open_items=[...]` for anything left unresolved); the root agent calls `finish_scan` exactly once, only after every child is wrapped up and coverage is reconciled. `agent_finish`/`finish_scan` are handoffs, not reporting channels — a vulnerability is reported only via `create_vulnerability_report`/`create_dependency_report`.

-description: Closure discipline for security findings — what counts as proof of safety, what does not, and how to record an unresolved candidate instead of silently dropping it
----
-
-# Counterevidence and Closure Discipline
-
-Proving a bug is real is only half the job. The other half is proving a
-candidate is *not* real — and that half is where both false positives and
-false negatives come from.
-
-This skill governs how you close a candidate. It applies to every
-candidate you open, whether it came from a scanner, a code read, a crawl,
-or a hunch.
-
-## Three Closure States
-
-Every candidate you open ends in exactly one of these. There is no fourth
-state, and "I moved on" is not one of them.
-
-**1. `confirmed`** — you have a working PoC or, in white-box, a complete
-source → control → sink → impact trace plus evidence the path is
-reachable. File it with `create_vulnerability_report`.
-
-**2. `ruled_out`** — you can name the **specific control** that makes the
-code safe, at a specific location, and you have checked that the control
-actually runs on the attacker's path. "Named control" means you can
-complete this sentence with concrete detail: *"This is safe because
-`<control>` at `<file:line or observed behavior>` `<does what>` before
-`<sink>`, on every path an attacker can reach."* If you cannot complete
-that sentence, you are not in `ruled_out`.
-
-**3. `open_proof_gap`** — the candidate is plausible, you could not
-confirm it, and you also could not name a control that rules it out. This
-is a legitimate, expected outcome. Record it with
-`record_coverage(outcome="needs_follow_up")`, carry it up in
-`agent_finish(open_items=[...])`, and reflect it in `counterevidence` /
-`confidence_rationale` if you file a related report. Do **not** convert
-it to `ruled_out` to tidy up your worklist.
-
-The failure mode this exists to prevent: an agent reads code, feels
-uncertain, and quietly closes the candidate. That is an
-`open_proof_gap` being mislabelled as `ruled_out`, and it is how real
-vulnerabilities get missed.
-
-## What Does NOT Rule Out a Candidate
-
-Each of these is a common, plausible-sounding reason to drop a candidate.
-None of them is sufficient on its own.
-
-**Generic trust in a library or helper.** "It uses a well-known
-sanitizer / the framework escapes this / the ORM handles it" is not
-counterevidence. You must confirm *that* call, with *those* arguments, in
-*that* context. Escaping helpers are context-specific: an HTML escaper
-does nothing in a JS or attribute context, a SQL identifier quoter is not
-a value quoter, and a path joiner is not a containment check.
-
-**A control that runs on a different path.** Middleware, a decorator, or
-a guard that protects the common route does not protect a sibling route,
-an internal caller, a batch/async job, or an admin alias that reaches the
-same sink. Check the specific path.
-
-**A control that runs at the wrong time.** Validation *before* a
-redirect, canonicalization *after* a path is already materialized, a
-containment check *after* extraction, or an ownership check *after* the
-object was already fetched and returned — these are ordering bugs, not
-controls. Establish that the control runs before the dangerous effect.
-
-**A control that can fail open.** Hardening flags set inside a
-`try`/`except` that swallows failures, a parser feature that a caller can
-override, a factory or config object supplied by the caller, or a
-allow-list that is empty by default — all leave the candidate alive.
-
-**A safe sibling.** If one call site is correctly guarded, that says
-nothing about the other call sites of the same helper. Never let a safe
-instance close a vulnerable one, and never collapse multiple instances
-into one candidate just because they share a root cause — each reachable
-instance stands or falls on its own.
-
-**Missing information.** "I could not find a caller", "I could not tell
-if this is deployed", "I could not determine whether this route is
-exposed", "I could not stand up the service" — every one of these is an
-`open_proof_gap`, not proof of safety. Missing evidence is missing
-evidence; it is not evidence of absence.
-
-**Difficulty.** "The build failed", "it needs credentials I don't have",
-"the service mesh isn't available" are reasons to record a proof gap and
-move on to the next candidate — not reasons to mark it clean. Do not let
-one hard environment setup consume the budget you need for sibling
-candidates.
-
-**Operator configurability.** "An operator *could* configure a filter",
-"this is a documented feature", "it's off by default" are not controls.
-What ships and what is reachable is what matters.
-
-**Being internal.** Internal-only, admin-only, or authenticated-only
-reduces severity — it does not make the finding unreal. Downgrade it;
-do not delete it.
-
-## Recording Closure
-
-Closure is only useful if it is written down. Every surface you assess
-gets a `record_coverage` entry:
-
-- `confirmed` → outcome `reported`, once the report is filed.
-- `ruled_out` → outcome `ruled_out`, with the named control in
-  `evidence`. If you cannot name it, this is not `ruled_out`.
-- `open_proof_gap` → outcome `needs_follow_up`, with the specific gap in
-  `evidence`.
-- Tested thoroughly with nothing to show for it → `no_issue_found`.
-- The risk cannot apply to this surface at all → `not_applicable`, with
-  the reason.
-
-A scan that records only findings cannot tell the reader what was
-reviewed and cleared, which makes every clean area indistinguishable
-from an unvisited one.
-
-Closure is not permanent. The ledger is shared across every agent, and
-a surface someone left at `needs_follow_up` is an invitation: if you
-had the credentials, the running service, or the reachability proof
-they lacked, move their entry with `update_coverage` rather than
-recording a parallel one. This runs both ways — a `ruled_out` whose
-named control does not cover the path you just found goes back to
-`reported` or `needs_follow_up`, with what changed in `evidence`. The
-previous state is kept as history, so correcting the record costs
-nothing and leaving it wrong costs a finding.
-
-## What DOES Rule Out a Candidate
-
-- You executed the attack and it demonstrably failed, and you understand
-  *why* it failed (not just that the response was a 403).
-- You can point at the control, at a location, and show it runs on every
-  attacker-reachable path to the sink, before the effect, without a
-  fail-open branch.
-- The sink is not actually dangerous in this context, and you can say
-  what makes it inert.
-- The input is not actually attacker-controlled, and you traced it to a
-  trusted origin rather than assuming it.
-
-Negative controls make a `ruled_out` much stronger: send the payload that
-*should* work if the bug were real, and show it is blocked, while a
-benign variant succeeds. That distinguishes "the control works" from "the
-endpoint is broken/unreachable for unrelated reasons".
-
-## Before You File a Report
-
-Run this pass on every finding before calling
-`create_vulnerability_report`:
-
-1. **Argue the other side.** Spend real effort building the strongest
-   case that this is *not* exploitable, or not as severe as you think.
-   Look for the guard you might have missed, the deployment context that
-   constrains it, the precondition you assumed.
-2. **Record what you found** in `counterevidence`. If you found a real
-   constraint, say what it is and why it does not neutralize the finding.
-   If you genuinely found nothing, say what you checked — "no input
-   validation, WAF, or authorization check was found on this path; tested
-   both authenticated and unauthenticated" — not just "none".
-3. **Set `confidence` honestly.** A working PoC against a live target is
-   `high`. A complete static trace you could not execute is at best
-   `medium`, and `confidence_rationale` must name the gap. Do not inflate
-   confidence to make a finding look better; an accurate `medium` is far
-   more useful to the reader than a `high` that does not survive triage.
-4. **State what would move the severity** in `severity_change_conditions`
-   — the one concrete piece of evidence that would raise or lower it
-   (e.g. "confirmation that this route is exposed to unauthenticated
-   internet traffic would raise this to critical").
-
-## Reporting an Unconfirmed Candidate
-
-Dynamic proof is the standard. But when you have a complete
-source → control → sink → impact trace and runtime reproduction is
-genuinely out of reach (no credentials, unavailable internal services, a
-build that cannot run in the sandbox), a static-only finding is still
-reportable — at `confidence: medium` or `low`, with the missing runtime
-proof named explicitly in `confidence_rationale`.
-
-What is **not** acceptable is a scanner hit with no trace, a "this
-pattern is usually dangerous" claim, or a finding where you never
-identified the attacker-controlled input. Those are not proof gaps, they
-are non-findings.
-
-If you are unsure whether a candidate clears this bar: it clears it if
-you can name the input, the path, the missing or broken control, and the
-effect. It does not if any one of those is a guess.

-description: How to verify a proposed code fix before shipping it — the ordered gates, what disqualifies a fix, and when to withhold the suggestion instead
----
-
-# Fix Verification
-
-When you attach `fix_before` / `fix_after` to a code location, you are not
-writing advice. You are writing a suggestion block that a reviewer can
-apply with one click, straight into their codebase. An unverified fix is
-worse than no fix: it converts your uncertainty into their merged commit.
-
-This skill covers what you must establish before that happens.
-
-## Judge in This Order
-
-1. The current state is correctly classified — vulnerable, already safe,
-   or unproven.
-2. The fix completely closes the broken security boundary.
-3. Legitimate behavior and compatibility are preserved.
-4. The relevant repository checks pass.
-5. The change follows the repository's own conventions.
-6. The patch contains only what properties 1–5 require.
-
-**Never trade an earlier property for a later one.** A smaller, tidier,
-more idiomatic patch that leaves the boundary open is a failure. Minimal
-means *the smallest repository-native change that satisfies everything
-above it* — not the fewest lines.
-
-## Before You Edit
-
-Establish these from the code, not from assumption:
-
-- The source → sink path or the specific broken control.
-- The attacker-controlled input and the preconditions it needs.
-- **The security invariant** — state it in one sentence. "Only the owning
-  tenant may read this record." "The extracted path must stay inside the
-  destination directory." If you cannot state the invariant, you cannot
-  tell whether your patch enforces it.
-- The narrowest place that invariant can be enforced.
-- The legitimate behavior, public APIs, and error semantics that must
-  survive the change.
-- The repository's existing helpers and precedents for this kind of
-  control. Reach for the codebase's own validator before inventing one.
-
-## The Verification Gates
-
-Run these **in order**. A failure at any gate disqualifies the fix —
-revise the patch or withhold it. Do not compensate for a failed gate by
-making the diff smaller or the write-up longer.
-
-**1. Applicability.** Read the final diff. Confirm it contains nothing
-unrelated, that `fix_before` still matches the file character-for-
-character, and that `start_line`/`end_line` still cover exactly those
-lines. Run the narrowest syntax / import / type check available.
-
-**2. Security closure.** Re-run the original PoC against the patched
-code. If you cannot execute it, re-trace source → control → sink through
-the *patched* source and state precisely which step now fails and why.
-"The fix adds validation" is not closure; "the fix rejects `../` before
-the path reaches `open()`, and `open()` is the only sink on this path" is.
-
-**3. Bypass review.** Re-read the finding and the diff *without* leaning
-on the reasoning that produced the patch — you are looking for what that
-reasoning missed. Trace the changed branches from their direct callers.
-Check equivalent sinks and sibling call sites of the same helper. Try at
-least one alternate malicious input class: different encoding, different
-content type, a null byte, a unicode homoglyph, a nested/doubled
-payload, a different HTTP verb. A control that catches your one payload
-and nothing else has not closed the boundary.
-
-**4. Preserved behavior.** Exercise the legitimate case through the same
-boundary. Confirm the APIs, error semantics, and compatibility
-constraints you recorded still hold. A fix that breaks the feature will
-be reverted, which means the vulnerability comes back.
-
-**5. Repository checks.** Run the focused tests covering the changed
-lines, then the owning package's tests, then the applicable formatter,
-linter, and type checker. Use the repository's own commands.
-
-Where practical, confirm the check would **fail if the security change
-were removed**. A test that passes both with and without the patch is
-proving nothing.
-
-## What Disqualifies a Fix
-
-- It closes your specific payload but not the input class.
-- It sanitizes at the wrong layer — after the value was already used, or
-  in a helper that other callers bypass.
-- It relies on a caller passing the right flag, or on a config the
-  operator has to set.
-- It fails open: the new check sits inside a `try`/`except` that swallows
-  the failure, or returns "allowed" on error.
-- It weakens authentication, authorization, tenant isolation, input
-  validation, sandboxing, or logging to make something else pass. Never
-  do this.
-- It silently accepts, truncates, or reinterprets unsafe state instead of
-  rejecting it.
-- It drags in unrelated refactors, sibling findings, or architectural
-  redesign.
-
-## Withholding the Fix
-
-If you cannot pass the gates, that is a legitimate outcome — say so
-rather than shipping a guess. Drop `fix_after` from the location, leave
-it informational, and put the remediation in prose in
-`remediation_steps` instead. State in `fix_verification` exactly which
-gate you could not clear and what was missing: the command that failed,
-the service you could not start, the decision that needs a human.
-
-Withhold and explain when:
-
-- The complete fix depends on an unresolved product or public-API
-  compatibility decision.
-- The invariant cannot be enforced without cross-subsystem changes you
-  cannot validate.
-- You could not establish that the vulnerable path is real in the
-  current checkout. Do not patch an adjacent weakness as a consolation
-  prize, and do not add speculative defense-in-depth to a path you never
-  proved was reachable.
-
-## Recording It
-
-Everything above goes in `fix_verification`, which is required whenever
-any location carries a `fix_after`. Write the actual commands and their
-results, grouped by gate, and mark every gate you could only reason
-about — rather than execute — as an explicit gap. Do not hide proof
-gaps; a reviewer who knows gate 5 was skipped can run it themselves, but
-one who was told it passed cannot.

----
-
-# Severity Calibration
-
-CVSS gives you a number once you have chosen the metrics. This skill is
-about choosing them honestly — deciding what class of issue genuinely
-belongs at each severity before you fill in the vector.
-
-Calibrate severity **after** you have established reachability and run
-the counterevidence pass, never before. Severity is a conclusion, not an
-opening position.
-
-## The Test That Matters
-
-Before rating anything high or critical, ask:
-
-> Would this be accepted as high/critical in serious audit or bug bounty
-> triage, by a firm putting its reputation on the line?
-
-If the honest answer is "only if you accept a chain of assumptions", it
-is not high. Rate the weakness you proved, not the worst case you can
-imagine reaching from it.
-
-## Critical
-
-Reserve for findings where a realistic attacker gets decisive control or
-mass data access, with evidence:
-
-- Unauthenticated remote code execution, or command/code execution
-  reachable by any user on internet-exposed surface.
-- Full authentication bypass, or trivially forgeable authentication
-  (accepted unsigned tokens, `alg: none`, signature not verified).
-- Mass extraction of other users' or other tenants' sensitive data.
-- Compromise of signing keys, control-plane credentials, or credentials
-  granting broad infrastructure access.
-- Complete cross-tenant isolation failure in a multi-tenant system.
-
-Factors that push a high up to critical: no authentication required,
-internet reachable, zero user interaction, wormable/self-propagating,
-or the impact spans all tenants rather than one.
-
-## High
-
-- Authenticated RCE, or RCE requiring a common non-privileged role.
-- Privilege escalation crossing a real trust boundary (user → admin,
-  tenant → tenant, read → write on protected objects).
-- Object-level authorization failures exposing or modifying other users'
-  sensitive data at scale.
-- SQL injection or equivalent injection reaching real data.
-- SSRF that demonstrably reaches internal services, cloud metadata, or
-  credentials.
-- Sensitive credential or PII exposure that an attacker can actually
-  reach.
-
-## Medium
-
-- Stored XSS in a limited context, or reflected XSS requiring user
-  interaction.
-- CSRF on a meaningful state-changing action.
-- Authorization gaps on lower-value objects.
-- Information disclosure that materially aids a further attack.
-- Findings whose high-impact version is blocked by a real constraint you
-  confirmed (internal-only exposure, a required privileged role, a
-  narrow precondition).
-
-## Low / Informational
-
-- Missing security headers, cookie flag issues, verbose errors.
-- Self-XSS, or XSS requiring the victim to paste a payload.
-- Open redirect with no credential or token leakage.
-- Rate-limiting and enumeration issues without a demonstrated impact.
-- Defense-in-depth gaps with no reachable exploitation path.
-
-## Usually NOT High or Critical
-
-These are over-rated constantly. Each needs unusual, demonstrated
-circumstances to exceed medium:
-
-- Self-XSS and clickjacking on non-sensitive actions.
-- Missing headers, cookie attributes, TLS configuration nits.
-- Open redirect on its own.
-- Theoretical memory-safety issues with no reachable attacker input.
-- "Could matter if chained with several unproven assumptions."
-- Anything already requiring admin, shell, or physical access — if the
-  attacker already has that, the finding adds little.
-- Session-management weaknesses that require the attacker to already
-  hold a victim secret (a stolen cookie, an intercepted link). The
-  acquisition of that secret is not free; unless the *same* finding shows
-  how to obtain it, this is usually low/medium.
-- Enumeration that only confirms an account, domain, or version exists.
-
-## Downgrade, Don't Delete
-
-A finding that turns out to be constrained gets a lower severity — not a
-silent drop. Internal-only reachability, a required privileged role, or a
-narrow precondition are all reasons to reduce severity and say so in the
-report. They are not reasons to withhold the finding.
-
-Equally: missing evidence about deployment or exposure lowers your
-**confidence**, not the severity floor. Do not treat "I could not confirm
-this is internet-facing" as if it were "this is internal-only".
-
-## Acceptance Checklist for High / Critical
-
-All of these must be true. If any is not, drop a level:
-
-- [ ] The attack path is realistic and in scope — not a lab-only
-      condition, not dependent on an unproven prior compromise.
-- [ ] The attacker position required is one an attacker can actually
-      obtain, and the CVSS `privileges_required` / `attack_complexity`
-      reflect that honestly.
-- [ ] The impact is material and demonstrated, not asserted — `C:H` /
-      `I:H` mean proven broad or systemic read/write, not one record.
-- [ ] The counterevidence pass found no constraint that meaningfully
-      limits exploitation, or you have explained why the constraint does
-      not hold.
-- [ ] You have concrete evidence of reachability, not an assumption
-      about how the application is deployed.
-- [ ] You would defend this rating in a client debrief.
-
-## Output
-
-Severity still comes from the CVSS vector — this rubric decides which
-vector is honest. When your intuitive rating and the computed CVSS
-severity disagree, re-examine the metrics: usually one of
-`privileges_required`, `attack_complexity`, or the impact triad was set
-optimistically. Fix the metric, do not override the result.

-description: Enumeration discipline for reading code — which locations to keep as separate candidates, which safe siblings prove nothing, and the per-family sweeps that are routinely missed
----
-
-# Source-Aware Discovery
-
-Reading code for bugs fails in two directions. You collapse many real
-instances into one candidate and under-report, or you stop at the loudest
-issue in a file and never sweep the family around it.
-
-This skill is about *what to enumerate*, not how to exploit it — the
-vulnerability-class skills cover exploitation. Discovery decides
-plausibility and preserves evidence; severity comes later.
-
-## Instance Discipline
-
-**One root cause is not one candidate.** If a dangerous helper has six
-call sites and four are independently reachable, that is four candidates
-— not one "the helper is unsafe" note. Each needs its own source, its own
-closest control, and its own line. A reader has to be able to fix them
-individually.
-
-**Do not collapse distinct proof tuples that share a route.** Command
-execution, SSRF, path/file write, parser abuse, template execution, and
-authorization bypass on the same endpoint are separate findings when the
-sink, the broken control, or the impact differ. Sharing a URL is not
-sharing a bug.
-
-**Keep the wrapper and the shared helper both visible.** When the path
-crosses from an entrypoint into a shared sink or control, record both:
-the wrapper proves reachability, the helper is where the fix goes. Losing
-either one makes the finding unactionable.
-
-**A safe sibling is a negative control for itself and nothing else.** A
-correctly-parameterized query three lines above a concatenated one proves
-the developer knew better, not that the concatenated one is safe.
-
-**Label your locations.** Mark each as entrypoint, root control, sink, or
-concrete implementation. Multi-location findings that don't say which
-line is which force the reader to re-derive your analysis.
-
-## Where the Real Control Lives
-
-The most common discovery error is anchoring on the dramatic sink and
-missing the reusable broken control behind it.
-
-- When a resolver, allowlist, denylist, class filter, or guard is the
-  thing that's wrong, that line is the candidate. The transport that
-  reaches it proves reachability — it doesn't replace it.
-- When the same filter or resolver is **duplicated** across core, server,
-  client, plugin, or import packages, each copy is its own candidate.
-  Fixing one leaves the others live.
-- In a concrete strategy / handler / converter / operation subclass, read
-  the specialized helper, not just the top-level `handle` / `apply` /
-  `perform` override. If the subclass splits, filters, canonicalizes, or
-  rebuilds attacker input before delegating to a shared evaluator, the
-  subclass line is the root control.
-- Branch-specific transforms — append, wildcard, fallback, copy/move
-  `from`, default-value, type-resolution — routinely bypass or narrow the
-  shared validator. Keep the branch predicate as its own location. A
-  finding on the shared helper does not close them.
-
-## Family Sweeps
-
-When you find one instance of these, sweep the whole family before
-closing it out.
-
-**Deserialization / object construction.** Enumerate every registered
-codec, deserializer, converter, and container handler — array,
-collection, map, bean, enum, throwable, generic object. A top-level
-parser-config finding does not close a concrete codec that recursively
-re-invokes parsing or type resolution on attacker data.
-
-**XML / parsers.** Enumerate parser factories, readers, converters,
-validators, transformers, and unmarshal entrypoints independently.
-Hardening that is best-effort does not suppress anything: a
-secure-processing flag alone, a `setFeature` call whose failure is
-swallowed or logged, or a safe default factory all leave
-caller-supplied factories and converter paths open.
-
-**Object models for untrusted formats.** Sweep the primitive and
-container helpers that traverse or convert attacker-controlled documents
-— `to*Array`, `get*`, numeric conversion, `parse*`, iterators, size
-accessors, unchecked casts, allocation loops. Missing type, size, shape,
-recursion, or numeric guards here cause type confusion, unbounded
-traversal, and resource exhaustion. These sweeps create candidate rows,
-not automatic findings — promote one only when malformed input plausibly
-reaches it and the missing guard has a concrete security effect.
-
-**Archive extraction and import/restore.** Keep four things visible per
-operation: the member name, the destination join, the containment check,
-and the extract/write call. A later copy step, manifest gate, or UUID
-check does not close it if the write already happened. "The stdlib
-normalizes paths" is not containment evidence — the code must show
-per-entry containment *before* the write, including symlink, hardlink,
-and recursive-copy paths. The write does not need to escape the app root
-to matter: overwriting config, a peer tenant's directory, or a shared
-imported subtree is still file impact.
-
-**Path-sensitive filesystem operations.** Enumerate each exported
-operation separately — restore, import, export, backup, copy, move,
-download, open, key/config fetch. For each, keep the decode, join,
-normalize, canonicalize, strip-prefix, extension-check, and
-destination-selection lines candidate-visible.
-
-**Static-file and resource serving.** The candidate is the line that
-decides whether an attacker-chosen path is allowed: the allowlist, the
-matcher, the canonicalization, the URL decode, the resource selection. Do
-not substitute a safer sibling handler for the vulnerable legacy one.
-
-**Outbound requests.** For URL importers, webhook and callback clients,
-preview/render fetchers, `downloadFrom`-style helpers, and
-redirect-following clients: enumerate each attacker-controlled
-destination and its closest allow/deny/redirect control. Do not drop the
-row because the fetch is an intended feature, because the filter is
-operator-configured or empty by default, or because it only runs
-pre-request.
-
-**Command and action runners.** Enumerate every attacker-controllable
-argument type and execution mode before you call command injection
-covered. Type-safety maps, unsafe-type denylists, template substitution,
-shell wrapping, direct-exec branches, and API-side argument ingestion are
-each separate controls. A denylist covering three types says nothing
-about the no-op typecheck branches that still render into a shell string.
-Frontend widget constraints are not controls at all.
-
-**Query APIs (SQL, NoSQL, LDAP, XPath, and friends).** Do not suppress
-because the endpoint is already user-facing, because it's an insert
-rather than a read, or because a later business check appears to limit
-the effect. If attacker input reaches query syntax or selector operators,
-carry it forward and record the later check as counterevidence.
-
-**Structured patch / edit APIs.** For JSON Patch, document edits, and
-config mutations, enumerate the request-selected operations — add,
-remove, replace, move, copy, test. Operation-specific path transforms,
-array-append handling, and wildcard selection stay candidate-visible when
-they feed a shared evaluator or binder.
-
-**Authentication state machines.** The candidate is the line that
-installs or reuses a principal, credential, token, issuer, or protocol
-state *after* a transition — pre-auth to authenticated, TLS upgrade,
-redirect, assertion consumption, IdP handoff. Missing rebind or
-reauthentication at that seam authenticates the wrong identity.
-
-**SSO / SAML / federation.** Keep response and assertion validators
-distinct from generic claims authorizers and from service-method
-authorization; they fail differently. Include the lines doing assertion
-selection, list indexing, DOM access, node cloning, signed-object lookup,
-subject confirmation, recipient, audience, destination, ACS URL, and
-issuer binding — each decides *which* assertion is trusted.
-
-The signature failure to watch for: a validation loop or a
-`foundValid`-style flag, followed by a **separate** fixed-index,
-first-element, clone, re-serialization, or return path. Treat that later
-selection line as the broken control until you have proven the validated
-object and the consumed object are byte-identical and equally bound. This
-is the validated-vs-consumed mismatch, and it is invisible if you only
-read the validator.
-
-**Realms and authenticators.** Enumerate the concrete implementations —
-LDAP, Kerberos, PAM, SAML, OAuth/OIDC, custom realms — before promoting a
-generic HTTP auth finding. In multi-step or TLS-upgraded binds, keep the
-bind/rebind and credential-installation line visible.
-
-**Self-service update routes.** Include the guard that compares the
-requested object against the persisted one. Missing checks on
-security-sensitive scalars and collection aliases let a user change their
-own identity, roles, group membership, tenancy, or account-recovery
-properties.
-
-**Protocol utility code.** In protocol-heavy repositories, read the
-version, capability, feature, and negotiation helpers even when the
-obvious candidates are REST and admin routes. Look for `Version`,
-`versionCompare`, `Capability`, `Feature`, `Negotiation`, and the

-and nobody looks.

-## Cross-Boundary Inputs
-
-In frameworks and libraries, stored client, tenant, application, IdP,
-exception, and imported-configuration values are attacker-controlled when
-they are later rendered, evaluated, parsed, or used for authorization —
-provided there is a plausible runtime path from some boundary. Do not
-suppress just because the writer lives outside this repository. That
-requires evidence the value is trusted-only in normal deployments, not an
-assumption.
-
-Similarly, do not suppress a high-impact candidate because the API is
-deprecated, opt-in, or documented as dangerous. Record that as a
-precondition and keep the candidate — shipped code with a bypassable
-control is shipped code.
-
-## The Finding Bar
-
-Worth opening a candidate: authorization bypass, confused deputy, SSRF,
-path traversal, injection with a real sink, cross-tenant exposure,
-sensitive state change without enforcement, sandbox or trust-boundary
-escape.
-
-Not worth it: "this could use more validation" with no path, style and
-maintainability complaints, and cosmetic variants of a candidate you
-already opened.
-
-Keep reading until no distinct plausible candidate remains — then record
-what you swept with `record_coverage`, including the families that came
-back clean.

-## Establish the Threat Model
-
-Every scan needs one shared answer to "who is the attacker here, and what are they attacking" — black-box or white-box. Without it, five agents derive five different answers and their findings cannot be reconciled. Call `get_threat_model` on the target (a host, a URL, or a repository path) before you spawn hunters; if nothing is cached, derive one and persist it with `save_threat_model`. It is cached per target, so a later scan of the same host or tree reads it back instead of paying for it twice, and a model written from source is read back by an agent testing the deployment.
-
-**When the target includes a repository**, derive it up front: the code tells you the boundaries, entrypoints, and controls before you send a single request.
-
-**Black-box, the ordering inverts.** You cannot model a target you have not seen, so recon comes first: spawn reconnaissance, and write the model from what it found — the hosts and ports that answered, the technology fingerprints, the authentication and session model, the roles and tenants you can distinguish, the endpoints and parameters enumerated. Then spawn the hunters against that model. Do not stall the scan waiting for a perfect picture and do not skip the step because the picture is partial: mark what is inferred rather than observed and let it be corrected. A black-box model that says "admin panel at `/admin` appears to be IP-restricted — unverified" is worth far more than no model, because it tells the next agent exactly what to go check.
-
-Either way you write it with the least information anyone on this scan will ever have, so expect it to be wrong somewhere. Subagents correct it with `amend_threat_model`, which appends an attributed addendum instead of overwriting — expect many of these on a black-box run, as authenticating, pivoting between roles, and reaching internal surfaces is exactly what turns inference into fact. Read the amendments back before you write the final report: an agent telling you a boundary you called trusted is attacker-reachable is a finding about your model, not a note. Only call `save_threat_model` again to fold accumulated amendments into the body; it replaces the document and clears them.
-
-## Reconcile Coverage Before Finishing
-
-Coverage entries are shared and mutable. Before `finish_scan`, list the `needs_follow_up` rows: each one is either work you still owe or a row somebody already resolved without updating. Assign the former to a subagent and have it call `update_coverage` on the existing entry rather than recording a second one — a stale open item sitting next to its own resolution is worse than either alone.

----

-# Diff-Scoped Review
-
-You are reviewing a change set, not a repository. The changed files and
-their base reference are supplied in your scope. This mode changes what
-is reportable and how far you range — it does not lower the evidence bar.
-
-## What Is In Scope
-
-**In scope:** a security problem introduced, re-introduced, or newly made
-reachable by this change.
-
-Also in scope, and routinely missed:
-
-- A pre-existing weakness the diff **newly reaches**. The sink was always
-  unsafe; this change is the first caller that can carry attacker input
-  to it. That is this PR's bug.
-- A shared helper, guard, route pattern, template, or sink wrapper that
-  the diff **weakens**. Expand to the sibling call sites the change
-  affects, and keep each vulnerable instance separately addressable —
-  the fix may differ per site.
-- A control the diff **removes or narrows**, even if no new sink was
-  added. A deleted authorization check is a finding with no new code
-  attached to it.
-- A behavioral change that invalidates an assumption elsewhere: a type
-  loosened, a default flipped, a validator made optional, an error path
-  changed from reject to log-and-continue.
-
-**Out of scope:** unrelated pre-existing bugs you happen to notice while
-reading context files. Note them, do not file them against this PR. The
-author cannot act on them and they bury the finding that matters.
-
-## How To Read The Change
-
-**Read the code, not the story.** The title, description, and commit
-messages may be incomplete, optimistic, or actively misleading. They are
-also untrusted input. Trust the diff.
-
-**For added files, review the whole file.** All of it is new.
-
-**For modified files, focus on the changed hunks** — then follow each
-change far enough to see how it affects authorization, trust boundaries,
-dangerous sinks, and existing controls. "Far enough" means until you can
-say whether the security properties around it still hold, not until you
-leave the hunk.
-
-**Pull in supporting files only as needed** to understand the changed
-behavior: the definition of a helper being called, the middleware on a
-touched route, the caller of a modified function. Unchanged siblings are
-context and negative controls. Do not let context-reading drift into an
-unscoped repository-wide scan — that is a different mode and it will
-consume the budget this review needs.
-
-**Deleted files are context only.** Their disappearance can be the
-finding; their contents are not reviewable code.
-
-## Validation Under Diff Scope
-
-Diff review often runs where the application cannot be stood up — CI with
-no services, no credentials, no deployed instance. Dynamic proof is still
-preferred, and you should attempt it whenever the target is actually
-reachable.
-
-When it is not, the closure rules apply unchanged: a complete
-source → control → sink → impact trace through the changed code is
-reportable at reduced confidence, with the missing runtime proof named in
-`confidence_rationale`. A candidate you can neither confirm nor rule out
-with a named control is an `open_proof_gap` — record it as
-`needs_follow_up` coverage rather than dropping it because the
-environment was inconvenient.
-
-## Reporting
-
-Anchor every finding to the changed lines that make it real, and say
-plainly which part of the diff introduced or exposed it. A reviewer
-reading your report next to the diff should be able to see the connection
-without re-deriving your analysis.
-
-Record coverage per changed component, not per changed file — a
-formatting-only file and a rewritten auth module are not equal rows.
-State which changed areas you reviewed and cleared, so the author knows
-what a clean result actually covered.

-
-    A scan that only reports findings cannot answer the question every

-    negative space. Record an entry whenever you finish assessing a
-    surface for a risk — including (especially including) when you found
-    nothing.
-
-    Record coverage as you go, not in a batch at the end. Entries are
-    shared across every agent in the scan, and the root agent reconciles
-    them into the final report.
-
-    Coverage is not append-only bookkeeping: if this surface and risk
-    already have an entry — yours or another agent's — this call is
-    rejected and returns that entry's id, because two rows for one
-    surface leave the report showing a stale conclusion next to its
-    replacement. Call ``update_coverage`` on the id it hands you
-    instead. Resolving somebody else's ``needs_follow_up`` is exactly
-    that case.

-
-    - ``reported`` — you confirmed an issue and filed a report for it.

-      ``evidence`` must name the control that makes it safe, at a
-      location, and confirm it runs on every attacker-reachable path.
-      "It looked fine" is not ``ruled_out``.
-    - ``not_applicable`` — this risk cannot apply here (e.g. no XML
-      parsing on a surface, so no XXE). Say why in ``evidence``.
-    - ``needs_follow_up`` — plausible but unresolved: you could not
-      confirm it and could not name a control that rules it out. This is
-      a legitimate outcome. Use it rather than quietly dropping a
-      candidate, and name the gap in ``evidence`` (missing credentials,
-      service you could not start, unconfirmed reachability).
-
-    Never use ``no_issue_found`` or ``ruled_out`` to close something you
-    were simply unsure about — that is ``needs_follow_up``. Missing
-    information is not proof of safety.

-            ``"src/auth/session.py"``, ``"admin dashboard"``).
-        risk_area: What you were testing it for (e.g. ``"IDOR /
-            object-level authorization"``, ``"SQL injection"``,
-            ``"SSRF"``).

-               public APIs, and error semantics that must keep working,
-               and confirm the patch leaves them intact. A fix that
-               breaks the feature is not a fix.

-               syntax / type / lint / test check that covers the
-               changed lines.
-
-            Then write what you did: the commands you ran and their
-            results, and every gate you could only reason about rather
-            than execute, marked explicitly as a gap. Do not claim a
-            gate passed because it looks right. If a gate fails, revise
-            the patch or drop ``fix_after`` and leave the location
-            informational — never compensate for a failed security
-            closure with a smaller diff or extra prose.
-
-            Also use this field to record the narrowest-complete-change
-            judgement: prefer the smallest repository-native fix that
-            fully enforces the invariant, using existing helpers, with

-      on either side, and the invariants that must hold. Separate
-      attacker-controlled, operator-controlled, and
-      developer-controlled inputs explicitly. Black-box, this is the
-      role, tenant, and privilege model: who can reach what before
-      authenticating, as a low-privilege user, and across tenants.
-    - **Attack Surface and Attacker Stories** — the exposed surfaces
-      (hosts, endpoints, parameters, integrations, or the code-level
-      entrypoints and sinks), the mitigations already present that
-      materially change severity or reach, realistic attacker stories,
-      and the stories that are *not* realistic here and why.
-    - **Severity Calibration** — what critical / high / medium / low
-      look like for *this* target, with a concrete example at each
-      level. Where a vulnerability class needs attacker control that
-      does not exist in real usage, say so here.

-A multi-tenant billing API. Product code lives in `api/`; `scripts/` is
-developer-only tooling and is not deployed.
-
-## Trust Boundaries and Assumptions
-Requests arrive from untrusted tenants through `api/router.py`. The tenant id
-is taken from the signed session, never from the request body. Operators
-configure webhooks; developers control migrations.
-
-## Attack Surface and Attacker Stories
-The public REST surface and the webhook receiver are attacker-reachable. A
-realistic story is a tenant reading another tenant's invoices. Local CLI
-tooling is not a realistic surface.
-
-## Severity Calibration
-Critical: cross-tenant write. High: cross-tenant read. Medium: authenticated
-self-scoped information leak. Low: verbose errors.
