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 5.1 | $0.00074 | $0.00662 |
| Opus 5.5 | $0.00030 | $0.00265 |
| Sonnet 5.5 | $0.00015 | $0.00132 |
| Haiku 4.5 | $0.00007 | $0.00066 |
Grade A, and why
changelog-page-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
100% identical to changelog-page-generator — 71 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 — 71 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Pages: Changelog
Guides changelog and release notes pages. Typically at changelog.* subdomain or /changelog. Builds trust, reduces support, increases feature adoption.
When invoking: On first use, if helpful, open with 1–2 sentences on what this skill covers and why it matters, then provide the main output. On subsequent use or when the user asks to skip, go directly to the main output.
Initial Assessment
Check for project context first: If .claude/project-context.md or .cursor/project-context.md exists, read it for product and release cadence.
Identify:
- Product type: SaaS, API, mobile app, etc.
- Audience: End users, developers, both
- Release cadence: Weekly, monthly, continuous
- Format: Timeline, version-based, category (New, Improved, Fixed)
Changelog Structure
| Section | Purpose |
|---|---|
| Entry | Date, version, title |
| Category | New, Improved, Fixed, Deprecated (optional) |
| Description | What changed, why it matters |
| Link | To docs, blog, or in-app |
| Media | Screenshots, GIFs, videos (optional) |
Best Practices
Content
- User benefit first: "You can now X" not "We added X"
- Concrete: Specific features, not vague "improvements"
- Scannable: Headlines, bullets, tags
- Searchable: If many entries, add search/filter
Organization
- Reverse chronological: Newest first
- Grouping: By version or date range
- Tags: Feature area, product module (optional)
- RSS/email: Notify subscribers of updates
Placement
- Subdomain: changelog.yourdomain.com
- Path: /changelog, /updates, /releases
- Embed: Widget in app or docs sidebar
- Link from: Footer, docs, in-app
Output Format
- Structure (layout, entry format)
- Entry template (fields, tone)
- Navigation (filters, search)
- SEO (index, metadata)
- Integration (embed, RSS, email)

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.
