<Tip>
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.
</Warning>

`package`, `ecosystem`, `installed_version`, `fixed_version`, `manifest_path`,
`introduced_by` for a transitive package, `dependency_path`, `cwe`,
`assumptions`, and the remediation instruction. A blank field costs the reader
a triage step.
### Contextual CVSS
The published score rates the CVE in the abstract. `contextual_cvss_breakdown`
rates it **here**, in this codebase, and every dependency report must carry
one. It is 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.
When you have no source-to-sink trace, still rate the finding: copy the
published metrics, change only the metrics the usage level itself proves, and
say so in the reasoning. For example, for a `not_imported` package that the
build still ships, keep the published metrics and lower `confidentiality`,
`integrity`, and `availability` to `N`, because no code path reaches the
vulnerable symbol. Never invent a hop you did not read.
`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."
When the published rating already fits this codebase, repeat the published
metrics in the breakdown and say in the reasoning that the deployment matches
the advisory. A contextual rating is a claim you must be able to defend, and it
never replaces `advisory_cvss` as the published reference.

it must be the real published value; do not guess or omit it.
technical_analysis: Optional deeper mechanism/root-cause detail.

reachability_evidence: **Required.** The concrete proof for the
claimed level, or, for ``unknown``, what you searched and why
the result is inconclusive: repo-relative
``file:line`` of the import or symbol usage, the matched
advisory symbols, or the govulncheck call-path excerpt.
Whenever you found the vulnerable symbol in use, also give the
**source-to-sink trace** here: start at the vulnerable package
call site and walk backwards hop by hop to the entry point
that carries untrusted input (HTTP route, CLI argument, queue
message, webhook, config file), going one step deeper whenever
a hop is a wrapper. Write it as ``entry point -> intermediate
call -> package call`` with a ``file:line`` per hop, name what
each hop enforces (auth, role check, validation, a flag that
is off in production), and say who controls the input. State
it plainly when no entry point reaches the sink — that is the
most useful result a reader can get.
contextual_cvss_breakdown: **Required.** Full CVSS v3.1 rating of this
CVE **in this codebase** — the same 8-metric object as
``create_vulnerability_report``'s ``cvss_breakdown``:
``attack_vector`` (N/A/L/P), ``attack_complexity`` (L/H),
``privileges_required`` (N/L/H), ``user_interaction`` (N/R),
``scope`` (U/C), ``confidentiality`` / ``integrity`` /
``availability`` (N/L/H). All 8 metrics are required when the
field is set, and the contextual score/vector are computed
from them — you never supply a score. Start from the
advisory's published metrics and change only what the
**source-to-sink trace** you recorded in
``reachability_evidence`` proves is different here: derive
``attack_vector`` / ``privileges_required`` /
``user_interaction`` from what the entry point actually
requires, ``attack_complexity`` from the preconditions the
hops enforce, and the impact metrics from the data and
privileges reachable at the sink. When provided, this rating
determines the finding's severity; ``advisory_cvss`` stays as
the published reference. Send it on every report: when the
trace does not change the published rating, or when you could
not complete the trace, repeat the advisory's own metrics and
adjust only what the usage level itself proves (a package the
code never imports is normally ``N`` on all three impact
metrics), then say so in the reasoning.
contextual_cvss_reasoning: **Required.** Two to four detailed
sentences that a reviewer can verify without opening the repo:
how the application uses the package, which call sites or
configuration you inspected (repo-relative ``file:line``),
which input reaches the vulnerable code and whether an
attacker controls it, and what the adjustment therefore
changes. State the source-to-sink chain explicitly, hop by
hop, as ``entry point -> intermediate call -> package call``
with a ``file:line`` for each hop. Cite concrete evidence,
never a generic statement such as "low risk". The user reads
this text next to the adjusted score, so an adjustment
without it is discarded.
