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 | $0.00031 | $0.00788 |
| Opus 5.5 | $0.00012 | $0.00315 |
| Sonnet 5.5 | $0.00006 | $0.00158 |
| Haiku 4.5 | $0.00003 | $0.00079 |
Grade A, and why
update-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 1mo 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 — 131 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Skill: update-pr-description
Generate a structured PR description from the actual branch diff and update the PR on GitHub.
Usage
/update-pr-description
/update-pr-description 463
/update-pr-description feature/lidar-l7-scene
If no argument is given, use the current branch and find the open PR for it.
Procedure
1. Identify the PR
If a PR number is given, use it directly. Otherwise:
git branch --show-current
Then find the open PR for that branch:
gh pr view --json number,title,body,state
If no open PR exists, stop and tell the operator.
2. Gather the diff
git log main..HEAD --oneline
git diff main --stat
Read the commit messages. They carry the intent. The diff stat shows the scope.
For large diffs, scan the actual changes in the most-modified files:
git diff main -- <file> | head -200
3. Categorise changes
Group changes into logical sections. Common categories:
- Feature or behaviour changes
- Refactoring or code quality
- Documentation rewrites or compliance passes
- Bug fixes
- Build, CI, or tooling changes
- Renames or file moves
Each category becomes a section heading in the PR description. Drop empty categories. If the PR only touches one category, skip the headings and write a flat description.
4. Draft the title
The PR title follows commit format: [prefix] Description.
Rules:
- Use the prefix(es) matching the dominant change type (
[docs],[go],[js], etc.) - If the PR spans multiple prefixes, use the primary one or combine:
[go][js] - The description should summarise the whole PR in one line, not just the first commit
- Keep it under 72 characters if possible
5. Draft the body
Structure:
One-sentence summary of what this PR does and why.
## Section heading
Paragraph or bullet list describing changes in this category. Be specific:
name the files, the functions, the migration. Do not pad.
## Section heading
...
## Checklist
- [x] Item that is done
- [ ] Item still pending (if any)
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.
