cadence: Skill for Claude Code

.claude/skills/pr-land/SKILL.md

pr-land is a skill for Claude Code from thomas-powers-jr/cadence. It costs 80 tokens per session (920 once invoked), scanned A, original, MIT.

A guided process for moving a code branch into a protected main branch through a pull request. It includes local checks, continuous-integration checks, merging, and updating the local copy afterward.

In plain words
What is it for?
Use it when work is ready to land, to open a pull request, wait for checks, squash-merge it, and synchronize the branch afterward.
Why use it?
It organizes the many steps required when direct pushes to the main branch are not allowed. It also handles known flaky checks and asks for consent before merging.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

pr-land scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

The opening of the file, as written. The whole thing — 79 lines — stays where its author put it; the contents beside it link to each section on GitHub.

PR land (protected main)

main requires the ci-success check and enforce_admins is on — there is no direct-push path, for anyone. Everything lands branch → PR → green → squash merge.

1 — Preflight locally (cheaper than a CI round-trip)

  • Run pnpm turbo run lint typecheck test build before pushing.
  • Windows caveat: Linux CI is canonical. A few Windows-local test failures are known environment issues (pnpm/tempRepo/spawn races) — if something fails only locally and the failure smells environmental, push and let the CI matrix decide rather than debugging the dev box.
  • Before any git operation that touches shared tree state — stash, reset, checkout onto main — re-check git status immediately beforehand, not from a check done minutes earlier in this same session. Another process (a subagent, a background build, a second terminal) can have changed the tree in between.

2 — Commit hygiene

  • Stage explicitly, never git add -A. Off-limits: live .cadence/state.json
    • STATE.md dirt mid-loop (the settle commit owns those), .agents/, launch/ (local-only by explicit decision), .claude/scheduled_tasks.lock, stray uncommitted SESSION-*.md handoffs.
  • Single-commit settle convention when a phase is closing: source + tests + docs + phase artifacts land together in one commit, no separate chore: settle commit after it.
  • Feature PRs carry their .changeset/*.md. Conventional-commit subject with the phase id: feat: <what> (phase NNN).

3 — Push + PR

git push -u origin <branch>
gh pr create --title "<subject>" --body "<what/why, invariants checked>"

One logical change per PR. The PR body ends with the standard 🤖 Generated with [Claude Code](https://claude.com/claude-code) footer.

4 — Babysit CI (the flake protocol)

  • Watch with gh pr checks <n> --watch (or poll gh pr checks <n>).
  • On red, get the failing leg + test before reacting: gh run view <run-id> --log-failed | head -100.
  • Re-run once, without investigation, only when all three hold: a single OS/Node leg is red, the diff can't plausibly touch the failing area, and the failure matches a known flake (reference: macOS/Node22 timeout in settle-codereview-convergence.test.ts; new node --test subprocess spawns under parallel load have flaked before).
  • Anything else — multiple legs, plausible relation to the diff, an unfamiliar failure, or a second red after the re-run — is real until proven otherwise: investigate, don't loop re-runs.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

pr-land is a skill published in the GitHub repository thomas-powers-jr/cadence (2 stars, last pushed 3d ago), licensed MIT. It adds 80 tokens to every session and 920 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
