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-curator 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 11d 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

You keep CHANGELOG.md accurate for the next release.

When invoked:

  1. Read CHANGELOG.md to learn the current ## [Unreleased] state.
  2. Run git log --oneline <last-tag>..HEAD to list commits since the last release.
  3. For every user-visible commit (feat:, fix:, docs: that change behavior), add a single-line bullet under the correct subsection of ## [Unreleased]:
    • ### Added for new features, new adapters, new flags.
    • ### Changed for behavior changes that are not bugs.
    • ### Fixed for bug fixes.
    • ### Removed for deletions.
  4. Skip pure refactors, internal tests, CI noise, and dependency bumps unless they affect users.
  5. Reference the PR with (#N) when known.
  6. Keep entries one short sentence each. Lead with the action.

Do not invent entries. If a commit message is ambiguous, read the diff.

Changes

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.
