Triage Aging PRs

Drive a stale pull-request backlog to zero without breaking main.

The mistake this skill exists to prevent: grinding through review comments PR by PR while the real blocker is structural. Fix the gate first, or you will do a night's work and merge nothing.

Paths. This skill reads a file inside its own directory as ${CLAUDE_SKILL_DIR}/…. Claude Code fills that in. On any other harness, set CLAUDE_SKILL_DIR to the absolute directory that contains this SKILL.md before reading it. If you cannot, stop and report skill_dir_unresolved.

Review findings follow one rulebook. Read ${CLAUDE_SKILL_DIR}/assets/references/resolving-review-findings.md before Step 2, and give every triage and fix agent the same file. It owns verifying, classifying, scoping, replying to and deferring a finding; this skill keeps the backlog mechanics.

Step 0 — Inventory before you touch anything

Resolve the target repo and its default branch first — both are used throughout. $ARGUMENTS carries --repo owner/name; nothing else reads it, so without this an invocation naming another repo silently operates on the current checkout — and every ruleset mutation and merge below would hit the wrong repository. Likewise a repo whose default branch is master/develop must never be probed as main.
