 Be specific. Good instructions help Strix prioritize the most valuable attack paths.
 </Tip>
+
+## 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.

+- Set `contextual_cvss_breakdown` + `contextual_cvss_reasoning` when this
+  codebase clearly changes the risk the published score describes (see below).
+
+### 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.
