fix-finding SKILL.md skillA

fix-finding from cowork-os/cowork-os is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add cowork-os/cowork-os/fix-finding@git:20260606.a4decec

Pins git:20260606.a4decec in mdr.lock. Pin the fingerprint instead.

Use when the user explicitly asks to fix and verify a validated or plausible security finding. Do not use as the primary trigger for full PR, commit, branch, patch, or repository scans.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Fix Finding

## Objective

Turn a security finding into a minimal, validated code change when the issue still exists. If the issue is already fixed, prove that with focused validation and report that no code change was needed. The result should include the fix if one was needed, focused regression tests or another repeatable validation check, proof that normal behavior still works, and proof that the original issue no longer reproduces.

## Inputs

Start by extracting any available finding details:

- title and affected component
- vulnerable source, sink, or broken control
- attacker-controlled input
- expected security invariant
- impact and required preconditions
- existing PoC, reproducer, test, or validation evidence
- files and line references

If a critical field is missing, inspect the repository to fill it from code evidence. Ask the user only when the fix would otherwise require guessing a product policy or security invariant.

## Note on Runtime Validation

Use this guidance whenever reproducing the finding, running tests, or validating the fix:

- Try hard to make runtime validation run before falling back to code inspection.

How to install

The exact contents, by fingerprint
mdr add cowork-os/cowork-os/fix-finding@sha256:41b9a5b26839b98d

The line at the top of this page pins the label git:20260606.a4decec, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
