lubot-hunter-mcp-2026: Skill for Claude Code

Verify a Candidate PR Actually Fixes the Issue

Goal: take a PR number, check it out cleanly, re-run the same tool call that failed on main, compare the outputs, and produce a verdict — "fixes", "fixes but with concerns", "does not fix", or "cannot run". Pair with /2-repro-issue (which produces the baseline). No edits, no merges, no pushes.

Phase 1 — Resolve the PR and its linked issue

# Accept "498", "#498", or "https://github.com/.../pull/498" — extract the digits only
PR=$(echo "$ARGUMENTS" | sed -E 's|.*/||; s|#||g' | grep -oE '^[0-9]+' | head -1)
[ -z "$PR" ] && { echo "Invalid input: '$ARGUMENTS'. Pass a PR number or URL." >&2; exit 1; }
REPO=stickerdaniel/linkedin-mcp-server

gh pr view $PR --repo $REPO --json title,body,baseRefName,headRefName,headRepositoryOwner,mergeable,mergeStateStatus,additions,deletions,changedFiles,maintainerCanModify,statusCheckRollup

Extract the linked issue number from the PR body (Closes #, Fixes #, Resolves #, or plain #N). Call it ISSUE. If multiple, ask the user which one is the verification target.

Phase 2 — Pick up the baseline + request metadata

/2-repro-issue writes two files for each issue:

• /tmp/repro-issue-<ISSUE>-main.json — the on-main response baseline
• /tmp/repro-issue-<ISSUE>-meta.json — the {tool, arguments} used to call it

Both must exist. The meta file is how this skill replays the exact same call instead of guessing tool and args from the response body.

ls -la /tmp/repro-issue-$ISSUE-main.json /tmp/repro-issue-$ISSUE-meta.json 2>&1
# Both files must exist AND be non-empty. ls alone never fails the script, so
# guard each path before we touch the PR branch or LinkedIn.
[ -s /tmp/repro-issue-$ISSUE-main.json ] || { echo "Missing or empty response baseline. Re-run /2-repro-issue $ISSUE." >&2; exit 1; }
[ -s /tmp/repro-issue-$ISSUE-meta.json ] || { echo "Missing or empty meta file. Re-run /2-repro-issue $ISSUE." >&2; exit 1; }
TOOL=$(jq -r .tool /tmp/repro-issue-$ISSUE-meta.json)
ARGS_JSON=$(jq -c .arguments /tmp/repro-issue-$ISSUE-meta.json)
echo "Replaying: $TOOL($ARGS_JSON)"
