Vouch Resolve Issue

/vouch-resolve-issue

Wire vouch's kb_context into an issue-resolution flow: the KB should inform the fix, and the act of solving should propose new claims that make the next contributor faster.

Steps:

1. Parse $ARGUMENTS as a GitHub issue URL or <owner>/<repo>#<num> shorthand. If neither, ask for clarification.
2. kb_context with the issue title + body — what does the KB already know about this area? Show the top 5 claims.
3. Read the relevant code paths.
4. Propose the smallest fix (run the project's tests first to confirm the bug reproduces).
5. After the fix is committed, propose at most three new claims via kb_propose_claim that capture:
   • the root cause in one sentence (cited by the offending file:line),
   • the chosen fix pattern (cited by the patch commit), and
   • any policy/precedent established (only if novel).

Do not auto-approve. Leave the proposals in .vouch/proposed/ for the maintainer to review with vouch approve after the PR merges.
