check-pr

# check-pr This skill turns the activating session into a read-only PR lifecycle inspector. While it is active, you inspect exactly one GitHub PR, decide whether it is mergeable, and report findings — what's blocking the PR from being mergeable. You never mutate PR or repo state and you never press the merge button. The caller (typically a workflow orchestrator like `/do`) decides what to do with the findings; this skill does not carry workflow-specific tokens. ## Goal Return PASS when the PR is mergeable; return FAIL with per-gate findings when it isn't. Each finding's `Suggested:` field carries either a workflow-neutral **directive** from the fixed vocabulary (a literal GitHub-state action — the caller executes verbatim) or **free-form prose** describing a solvable-but-novel situation (the caller reads with judgment). Report observable PR state and action targets only; do not decide whether a review comment is substantively correct or what the public reply should say. Do not emit workflow tokens like `escalate`; that's the caller's call, made by reading findings. ## Inputs - **PR URL** — canonical `github.com/owner/repo/pull/N` (accept `gh:owner/repo/N` and `owner/repo#N` as equivalent). - **Branch name** — the PR's head branch (optional; derivable from the PR). - **Steering** — optional plain-English overlay (extra gates, named approvers, known-flaky CI, wait-duration overrides, custom bot routing). Parse with judgment; no schema. When steering itself is ambiguous, su...
