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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00029 | $0.00453 |
| Opus 5 | $0.00015 | $0.00227 |
| Sonnet 5 | $0.00006 | $0.00091 |
| Haiku 4.5 | $0.00003 | $0.00045 |
Grade A, and why
changelog 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 4d 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
Changelog Generator
Generate a clean, categorized changelog from git commits.
Process
1. Gather Commits
Use $ARGUMENTS as starting point (tag or date). Default: last 2 weeks.
# From a tag
git log --oneline --no-merges v1.0.0..HEAD
# From a date
git log --oneline --no-merges --since="$ARGUMENTS"
# Default
git log --oneline --no-merges --since="2 weeks ago" | head -50
2. Categorize Changes
- ✨ New Features — new functionality visible to users
- 🔧 Improvements — enhanced existing functionality
- 🐛 Bug Fixes — resolved defects
- 🔒 Security — CVE fixes, dependency upgrades
- ⚠️ Breaking Changes — API changes, schema migrations
- 📝 Documentation — doc updates
3. Filter Noise
Exclude: refactoring, test-only changes, CI/CD changes, merge commits, lint formatting
4. Translate to User-Friendly Language
- Remove ticket prefixes
- Replace internal service names with user-facing terms
- Focus on what changed for the user, not how
5. 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.

changelog is a skill published in the GitHub repository brain-bootstrap/claude-code-brain-bootstrap (11 stars, last pushed 4mo ago), licensed MIT. It adds 29 tokens to every session and 453 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings.
