PR Review Comment Fixer

Fetch unresolved PR review threads, analyze each one, propose fixes, then implement whatever the user approves.

Phase 1: Fetch threads

Check whether gh is on PATH: command -v gh. Some sessions (e.g. a remote/cloud session) have no gh CLI and use mcp__github__* tools instead.

gh available: run ${CLAUDE_SKILL_DIR}/scripts/fetch-review-threads.sh via the Bash tool. It resolves the current PR, fetches review threads, review bodies, and issue comments, and filters out resolved threads and empty bodies with jq before any of it reaches you: you only ever see live, unresolved feedback. Output is {threads, reviews, issueComments}. If the script fails to resolve a PR for the current branch, ask the user for the PR number or URL and retry.
