Token cost

What it costs to keep this loaded

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.

Security

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 8d 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 — 98 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Changelog Generator Skill

Converts raw git commits, a diff summary, or developer release notes into a polished changelog entry — categorised, user-facing, and following Keep a Changelog conventions.

Required Inputs

Ask for these if not provided:

  • Commits or release notes (paste git log --oneline, raw commit messages, or a description of what changed)
  • Version number (e.g. 2.4.0, v1.0.0-beta.2)
  • Release date (or "today")
  • Audience (developers using an API / end users of a product / internal team — affects language)
  • Any breaking changes (flag these explicitly if known)
  • Previous version behaviour (optional — paste the previous changelog entry or describe what is changing; needed for accurate "Changed" entries)
  • Scope (whole product / specific package or module — e.g. "payments SDK only", "iOS app", "all services")

Output Format

Follow Keep a Changelog format:


[X.Y.Z] — YYYY-MM-DD

Breaking Changes ⚠️

[Only include if there are breaking changes]

  • [Breaking change]: [What changed and what it breaks]
  • Migration required: [Specific action the user must take]

Added

  • [New feature or capability, written from the user's perspective]
  • [Another addition]

Changed

  • [Changed behaviour — what it did before vs. what it does now]
  • [Performance improvement with measurable impact if known]

Fixed

  • [Bug fixed — describe what was broken, not the fix implementation]
  • [Another fix]

Deprecated

  • [Deprecated thing] — use [replacement] instead. Will be removed in [version].

Removed

  • [Removed thing] — was deprecated in [version]

Security

  • [Security fix — describe the vulnerability class, not exploit details]


Skill guidance — do not include the following section in the delivered changelog:

Formatting Rules Applied

Language: Write for the reader, not the committer. "Add dark mode support" not "implement ThemeProvider with dark palette variant".

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.
