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

generate-changelog 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.

What it actually says

Generate a changelog from git history, grouping commits by type and version.

Steps

  1. Determine the version range:
    • If --from and --to are specified, use those tags.
    • Otherwise, generate from the last tag to HEAD.
    • For initial changelog, process all commits.
  2. Parse commits using conventional commit format:
    • feat: Features section.
    • fix: Bug Fixes section.
    • perf: Performance section.
    • docs: Documentation section.
    • refactor: Code Refactoring section.
    • test: Tests section.
    • chore/ci/build: Maintenance section.
    • BREAKING CHANGE: Breaking Changes section (always first).
  3. For each entry, include:
    • Commit subject line.
    • Scope in parentheses if present.
    • PR number or commit hash as reference.
    • Author attribution.
  4. Sort sections by importance: Breaking > Features > Fixes > Performance > Others.
  5. Write or update CHANGELOG.md with the new version at the top.
  6. If existing CHANGELOG.md exists, prepend the new version section.

Format

Rules

  • Skip merge commits and CI-only changes.
  • Link version headers to git comparison URLs when possible.
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.
