summary

A concise implementation summary for a GitHub pull request, which is a request to review and merge code changes. It examines the branch's changes, documentation, commits, and current name, then saves the summary as a Markdown file.

In plain words
What is it for?
Use it to prepare a PR summary after reviewing the branch against main, update documentation first, and save the result under plans using the branch name.
Why use it?
It turns a collection of code changes into a consistent explanation of what changed, why it changed, and how it was checked. This reduces the work of writing a clear pull-request description.

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

summary 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 2d 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.

What it actually says

Generate a concise implementation summary for a PR description.

Read AGENTS.md first. It is the canonical project guide for this repository.

Steps:

  1. First, run the /docs skill to ensure documentation is up to date with the branch changes
  2. Run git diff main...HEAD --stat and git log main..HEAD --oneline to understand all changes on this branch
  3. Read the changed files to understand what was implemented and why
  4. Get the current branch name: git rev-parse --abbrev-ref HEAD
  5. Write a summary suitable for a GitHub PR description
  6. Save the raw markdown summary (without the wrapping code fence) to plans/<branch-name>-summary.md, replacing any / in the branch name with -

Summary format rules:

  • The summary must be GitHub-flavored markdown that renders nicely in a PR description
  • Do NOT use any headings (#, ##, ###, etc.) — structure the summary with bold labels and line breaks instead
  • Use **bold** for section labels (e.g., **What:**, **Why:**, **Changes:**)
  • Use backtick-wrapped inline code for file names, config keys, commands, and identifiers
  • Use markdown bullet points (-) for listing changes
  • Use numbered lists for verification steps
  • Use [text](url) for hyperlinks when referencing issues or external resources
  • Start with **What:** — a one-line statement explaining the change
  • Follow with **Why:** — 2-3 sentences max explaining the motivation
  • Include **Changes:** — key changes as bullet points (no nested bullets)
  • If there are new tests, add **Tests:** with one line describing coverage
  • End with **How to verify:** — concrete steps as a numbered list
  • Keep the total summary under 30 lines
  • Do not repeat file paths or class names unnecessarily
  • Focus on behavior changes, not implementation details
  • Write in present tense, active voice

Output rules:

  • Do NOT print the summary to the conversation
  • Only save it to the file and tell the user where it was saved: "Summary saved to plans/<branch-name>-summary.md"

Do NOT:

  • Use headings (#, ##, ###) anywhere in the summary
  • Use tables or badges
  • List every single file changed
  • Include generic boilerplate like "This PR adds..."
  • Add emojis
  • Over-explain things that are obvious from the diff
  • Print the summary content in the conversation output

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.
