patch-advisor
Recommends the specific code change to remediate a detected vulnerability by dispatching on CWE to the matching Project CodeGuard rule's prescribed fix pattern. Use after a finding has been confirmed and located, when the user asks how to fix a vulnerability, or when generating remediation PRs.

Patch Advisor
This skill delegates to Project CodeGuard for remediation patterns. Every CodeGuard rule includes an "Implementation Checklist" and concrete before→after code; this skill is the CWE→rule→fix lookup.

Workflow
- Take CWE + language from the upstream finding.
- Look up the rule; extract the fix pattern for that language.
- Emit: the minimal diff, the rule ID it satisfies, and the rule's test-plan line for verification.
- If the CWE isn't in the table, fall back to the CodeGuard language→rules map and apply the closest rule's Implementation Checklist.
