In plain words
What is it for?
Use it to draft a pull-request title and concise sections covering the reason for the change, important behavior, testing, and relevant warnings.
Why use it?
It helps reviewers quickly understand why the change exists, what matters, and how it was tested without reading a long summary.

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

caveman-pr 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 9d 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.

How it starts

The opening of the file, as written. The whole thing — 140 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Write PR descriptions terse and exact. Reviewers don't need a tour of your diff — they need a why, a how-tested, and (if relevant) a heads-up.

Rules

Title:

  • Same shape as the squash-merge commit subject — Conventional Commits if the project uses them (feat(scope): ..., fix(scope): ...).
  • ≤ 72 chars; ≤ 50 if possible.
  • Imperative mood ("add", "fix", "remove" — not "added").
  • No [WIP] — use a draft PR instead.
  • No emoji unless the project already does it.

Body — at most 4 sections, in this order. Omit any that don't add signal.

Why (almost always mandatory)

  • 1–3 sentences. Link the plan / RFC / ADR / Jira ticket / issue if that's the why.
  • Skip ONLY when the title is genuinely self-explanatory (e.g. fix(billing): guard against zero-cap users — title says everything).

What changed (often skippable)

  • ONLY include if the diff isn't obvious from a 30-second skim.
  • Bullets of structural changes. Don't restate file paths the reviewer will see anyway.
  • Drop "Refactored", "Cleaned up" — say what behavior changed.

How tested (mandatory)

  • One or two lines. Command run + result. Or a link to QA artifacts.
  • Web change: link to .orc/<branch>/files/qa/steps.md (or wherever orc's QA evidence lives).
  • "Tests: 47 pass, 0 fail." beats "Wrote tests for the new branch and they all pass."

Notes (only if there's something real)

  • Breaking changes — call out, including the migration step.
  • Risks the reviewer should look at twice.
  • Follow-up issues filed.
  • Skip platitudes ("clean code", "all tests pass" — already covered).

Trailers (footer, not a section)

  • Closes #42, Refs #17, Fixes ENG-712 — one per line at the very bottom.
  • No AI attribution. No Co-Authored-By: Claude. No Generated with….

What NEVER goes in

  • "This PR does X" — the title and diff already say it.
  • "Please review carefully" / "Let me know what you think" — reviewer knows their job.
  • Line-by-line restatement of the diff.
  • Marketing voice ("This game-changing refactor unlocks…").
  • Emoji-stuffed checklists if the repo's PR template doesn't require them.
  • AI attribution of any kind.
  • A "Screenshots" section with placeholder text — either include real screenshots/links or omit.

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.
