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 | $0.00033 | $0.00231 |
| Opus 5 | $0.00016 | $0.00115 |
| Sonnet 5 | $0.00007 | $0.00046 |
| Haiku 4.5 | $0.00003 | $0.00023 |
Grade A, and why
release-notes 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 yesterday.
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
Release Notes
Turn implementation details into user-facing release notes.
Process
- Identify the user-facing outcome.
- Group related implementation details into one bullet.
- Avoid internal file names unless the user asks for engineering notes.
- Keep the tone factual and concise.
When the user provides a rough list of changes, run
scripts/format-release-notes.ts with { "changes": [...] } to create a first
draft, then polish the wording for the user's audience. The TypeScript script
is function-style (export default run(input, ctx)) and demonstrates reading
references/style-guide.md from ctx.files.
Output format
Use this structure:
## Summary
- One to three bullets describing what changed.
## Notes
- Optional caveats, migration details, or follow-up work.
If the input is too vague, ask for the target audience and the release scope.
What ships with it
2 files 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.
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.

release-notes is a skill published in the GitHub repository cloudflare/agents (5,498 stars, last pushed 2d ago), licensed MIT. It adds 33 tokens to every session and 231 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
