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 | $0.00048 | $0.00666 |
| Opus 5.5 | $0.00019 | $0.00266 |
| Sonnet 5.5 | $0.00010 | $0.00133 |
| Haiku 4.5 | $0.00005 | $0.00067 |
Grade A, and why
changelog-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 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.
This is a copy
97% identical to changelog-generator — 1 line 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 — 105 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Changelog Generator
This skill transforms technical git commits into polished, user-friendly changelogs that your customers and users will actually understand and appreciate.
When to Use This Skill
- Preparing release notes for a new version
- Creating weekly or monthly product update summaries
- Documenting changes for customers
- Writing changelog entries for app store submissions
- Generating update notifications
- Creating internal release documentation
- Maintaining a public changelog/product updates page
What This Skill Does
- Scans Git History: Analyzes commits from a specific time period or between versions
- Categorizes Changes: Groups commits into logical categories (features, improvements, bug fixes, breaking changes, security)
- Translates Technical → User-Friendly: Converts developer commits into customer language
- Formats Professionally: Creates clean, structured changelog entries
- Filters Noise: Excludes internal commits (refactoring, tests, etc.)
- Follows Best Practices: Applies changelog guidelines and your brand voice
How to Use
Basic Usage
From your project repository:
Create a changelog from commits since last release

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.
