Label a PR's type, size, and risk with classify_pull_request

Apply type:*, size:*, and optionally risk:* labels to a pull request, with size computed automatically from its diff.

Prerequisites

• github-pull-requests installed.
• An open (or any existing) pull request in the target repository.
• Write access sufficient to create labels and modify a PR’s labels.

Steps

1. Pick a type from feat, fix, chore, docs, refactor, test, perf.

2. Optionally pick a risk from low, medium, high. Omit it if you don’t want risk managed by this call.

3. Call classify_pull_request:

   {
     "owner": "your-org",
     "repo": "your-repo",
     "pullNumber": 12,
     "type": "fix",
     "risk": "low"
   }

4. Read the response: { type, size, risk, changedLines, changedFiles, labelsApplied, labelsRemoved }.

Verify it worked

Check labelsApplied contains type:<your type>, size:<computed size>, and (if supplied) risk:<your risk>. Open the PR on GitHub and confirm the same labels are visible.

Notes

• Size is computed from additions + deletions: XS (<10 lines), S (<30), M (<100), L (<500), XL (≥500) — the Danger.js / PR-size-labeler convention, not a plugin-specific scale.
• Re-running this call with a different type or risk replaces the stale label of that category (reported in labelsRemoved); it does not accumulate multiple type:* labels on the same PR.
• Omitting risk on a later call leaves any existing risk:* label untouched — it is not cleared just because you stopped supplying it.
• Missing labels (type:fix, size:M, etc.) are created automatically on first use, with fixed colors per category.
