Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00035 | $0.01253 |
| Opus 5 | $0.00017 | $0.00626 |
| Sonnet 5 | $0.00007 | $0.00251 |
| Haiku 4.5 | $0.00003 | $0.00125 |
Grade A, and why
pr_description_generator 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 6d 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.
This is a copy
89% identical to pr-description-generator — 8 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 215 lines — stays where its author put it; the contents beside it link to each section on GitHub.
PR Description Generator
When to Use This Skill
Activate this skill when the user:
- Asks to "create a PR description" or "describe this PR"
- Says "generate PR description" or "write PR description"
- Mentions "pull request" in context of documenting changes
- Asks to "update PR description" for an existing PR
Core Process
Step 1: Locate the PR Description Template
Check for template in standard locations:
# Project-specific template
test -f thoughts/shared/pr_description.md && echo "Found"
# Alternative locations
test -f .github/pull_request_template.md && echo "Found"
test -f docs/pr_template.md && echo "Found"
If no template exists, offer to use a standard format or create one.
Step 2: Identify the Pull Request
Check current branch for associated PR:
gh pr view --json url,number,title,state 2>/dev/null
If no PR exists, offer to describe changes for a new PR or list open PRs.
Step 3: Gather Comprehensive PR Information
Collect all PR context:
# Full diff of changes
gh pr diff {number}
# Commit history
gh pr view {number} --json commits
# Metadata
gh pr view {number} --json url,title,number,state
For new PRs (not yet created):
git diff main...HEAD
git log main..HEAD --oneline
git diff --name-only main...HEAD
Step 4: Analyze Changes Thoroughly
Deep analysis required - Think carefully about:
- Code changes: Read the entire diff, understand purpose and impact
- User-facing impact: What will users notice? Breaking changes?
- Implementation details: Technical approach and decisions
- Migration requirements: Data migration, deployment steps
Step 5: Handle Verification Requirements
Process checklist items from template:
- Identify automated checks:
npm test,make build, etc. - Run what you can and mark results
- Document what couldn't be completed
Step 6: Generate the Description
Fill out each section from the template:
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.
