-## Workspace files
-
-Instructions become part of the prompt. To give Strix a file to work with, such
-as a wordlist, an API specification, or notes, use `--workspace-file`. Strix
-places the file into the sandbox workspace before the scan starts.
-
-```bash
-strix --target https://app.com --workspace-file ./wordlist.txt
-```
-
-The file lands at `/workspace/<file name>`. To choose the destination, write
-`PATH:DEST`. `DEST` is a path inside `/workspace`.
-
-```bash
-strix --target https://app.com \
-  --workspace-file ./openapi.yaml:specs/openapi.yaml \
-  --workspace-file ./notes.md
-```
-
-Repeat the option for every file you want to place. Strix lists the files in the
-agent task, so the agent knows where to read them.
-
-Rules that apply to every workspace file:
-
-- The file is read-only inside the sandbox.
-- The destination must stay inside `/workspace`.
-- The destination must not fall inside a target directory, because target files
-  come from the target itself. Strix skips such a file and logs a warning.
-- Two files cannot claim the same destination.
-
-<Note>
-A workspace file is data for the agent to use. It is not a scan target, and its
-contents do not change the instructions.
-</Note>
-
-<Warning>
-Do not place secrets in a workspace file. The sandbox runs untrusted target
-code, so treat anything you place there as readable by the target.
-</Warning>

-### Contextual CVSS
-
-The published score rates the CVE in the abstract. `contextual_cvss_breakdown`
-rates it **here**, in this codebase — the same 8-metric CVSS v3.1 object as a
-normal finding's `cvss_breakdown` (`attack_vector`, `attack_complexity`,
-`privileges_required`, `user_interaction`, `scope`, `confidentiality`,
-`integrity`, `availability`). You never pass a score: the contextual score and
-vector are computed from the breakdown, and when you provide one it determines
-the finding's severity. `advisory_cvss` stays the published reference.
-
-Start from the advisory's own published metrics and change only what your
-evidence proves is different in this codebase:
-
-- `attack_vector` `N`/`A`/`L`/`P` — as deployed. A library reached only by a
-  local CLI is `L`, not `N`.
-- `attack_complexity` `L`/`H` — raise to `H` when the vulnerable path needs a
-  precondition the code enforces (input validation, a non-default flag, an
-  internal-only route).
-- `privileges_required` `N`/`L`/`H`, `user_interaction` `N`/`R` — what this
-  deployment requires before the path is reachable.
-- `scope` `U`/`C` — whether exploitation here escapes the component boundary.
-- `confidentiality`/`integrity`/`availability` `N`/`L`/`H` — the impact in this
-  codebase. `not_imported` code the build still ships is usually `N` across all
-  three.
-
-Ground every metric in the **source-to-sink trace** from the usage analysis
-(step 3 above), not in a general impression of the package. Derive the metrics
-from that chain: `attack_vector`, `privileges_required`, and `user_interaction`
-come from what the source requires; `attack_complexity` comes from the
-preconditions the hops enforce; `confidentiality`, `integrity`, and
-`availability` come from the data and privileges available at the sink.
-
-No trace, no contextual breakdown: if you did not reach a symbol hit, or you
-could not follow a hop, omit the contextual fields instead of guessing.
-
-`contextual_cvss_reasoning` is required with the breakdown. Write two to four
-sentences that another engineer can check without opening the repository. Name
-the chain hop by hop as `entry point -> intermediate call -> package call`, with
-a repository-relative `file:line` for each hop, say who controls the input, and
-say what the contextual rating changes. Example: lowering `attack_vector` to
-`L` and `confidentiality` to `L` with "The only caller of `yaml.load` is
-`parse_manifest` in `scripts/import.py:88`, which `cli/commands.py:212` invokes
-for an operator-supplied path behind the `--allow-unsafe-import` flag that
-`deploy/prod.yaml` never sets. No HTTP route reaches that function, so an
-attacker must already hold shell access on the job host, and the parsed data is
-build metadata rather than customer records."
-
-Omit all the contextual fields when the published rating already fits, and when
-the evidence is thin. A contextual rating is a claim you must be able to
-defend, and it never replaces `advisory_cvss` as the published reference.
