Adds `tools/pr` as the maintainer-only control plane for PR-duty work on
this repo. Thin `gh` wrapper that encodes repo-specific knowledge:
review lanes, forbidden surfaces, lane-specific checklists, validation
command derivation from touched packages.
Subcommands:
- `list` — triage open queue by lane and review-state bucket.
- `view <num>` — agent-friendly review brief for a single PR.
- `classify [num]` — emit script-level tags for one PR or the whole
open queue; full-queue JSON output lands under `.tmp/tools-pr/classify/`
with rate-limit telemetry per run.
- `assignment` — assigner-perspective view of PR ownership, idle time,
and blockers (derived from existing tags; no new judgments).
Tag dictionary (13 tags) covers: bot-only-approval, needs-rebase,
forbidden-surface, unlabeled, duplicate-title, non-ascii-slug,
maintainer-edits-disabled, org-member, unresolved-changes-requested,
stale-approval, and three awaiting-* timing tags. Each rule is
expressible as one factual sentence over `gh` data + repo paths — see
`tools/pr/AGENTS.md` for the full dictionary plus precision rules.
Templates in `tools/pr/templates/*.md` are aesthetic references for
recurring maintainer comments (duplicate-title ask, awaiting-author
nudge, agent-review brief shape). `templates/examples/` holds
frozen-in-time agent-review snapshots for three PR shapes.
Infrastructure:
- `gh()` wraps `execFile` with minimum-touch retry (2 attempts at 1s + 2s
backoff) on transient 5xx / network errors. Persistent failures still
surface — retry is anti-jitter, not an exponential-backoff resilience
layer.
- Heavy chunks (`reviews`, `comments`, `commits`, assignment timelines)
use cursor-paginated `gh api graphql` via `fetchPaginatedPrList` to
stay under GitHub's GraphQL server-side timeout. Light chunks stay on
`gh pr list --json`.
- `fetchOrgMembers` cached per process via `gh api orgs/<owner>/members
--paginate`.
Wiring:
- Root `package.json` adds `pnpm tools-pr` to the allowed root entry
points.
- `scripts/postinstall.mjs` builds `tools/pr` alongside other workspace
packages.
- `scripts/guard.ts` allowlists `tools/pr/bin/tools-pr.mjs` and
`tools/pr/esbuild.config.mjs`, and adds `pr/` to the `tools/` top-level
layout allowlist.
- Root `AGENTS.md` and `tools/AGENTS.md` document the new command
surface, root-command-boundary update, and per-tool ownership.
