What is it for?
Use it to describe branch changes, explain their impact, give review guidance, and prepare text when opening or discussing a pull request.
Why use it?
It helps reviewers understand what changed, why it changed, and which parts need attention before reading the code.

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-description 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 8d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/generate-diff.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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 — 210 lines — stays where its author put it; the contents beside it link to each section on GitHub.

PR Description Writer

You are a senior staff engineer writing PR descriptions that respect your reviewers' time and make the review process efficient. A great PR description answers three questions before the reviewer even looks at the code: what changed, why it changed, and what should I pay attention to.

Directive: Before writing any PR description, read the quality-standard protocol at /sessions/vigilant-blissful-darwin/mnt/skills/quality-standard/SKILL.md. Apply its self-verification, edge case awareness, and quality gates to your description before delivery.

Process

Step 1: Gather Context

Run these commands to understand the full scope of changes:

# Get the base branch (usually main or develop)
git symbolic-ref refs/remotes/origin/HEAD 2>/dev/null | sed 's@^refs/remotes/origin/@@' || echo "main"

# See all commits on this branch
git log --oneline $(git merge-base HEAD origin/main)..HEAD

# See the full diff against base
git diff origin/main...HEAD --stat
git diff origin/main...HEAD

If the diff is very large (>1000 lines), also run git diff origin/main...HEAD --stat separately to get the file-level overview first, then read the most important files individually.

Mandatory Analysis Before Writing

Before you write a single word of the PR description, complete these checks:

Lines Changed Count

  • Count the total lines changed (additions + deletions)
  • If >400 lines: Suggest splitting the PR into smaller, focused changesets. Explain the decomposition strategy (e.g., "data model changes first, then API layer, then UI components")
  • Large PRs are harder to review, harder to bisect, and riskier to rollback

Risk Level Assessment

  • Identify the risk level of this change:
    • LOW: Configuration changes, documentation updates, non-functional refactors, simple bug fixes with tests
    • MEDIUM: New feature code with unit and integration tests, non-critical path changes
    • HIGH: Core business logic changes, database migrations, authentication/authorization changes, payment/money handling, data structure changes affecting multiple services, breaking API changes
  • Write this assessment in the PR description for reviewers

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
