fix-finding skillA

fix-finding is agent-read markdown (skill) from cowork-os/cowork-os: 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..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns 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.

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
