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 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 10d 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 changelog from $ARGUMENTS:

  1. Parse arguments: Extract the starting point (tag, date, or commit hash) and optional repo path (default: current directory)
  2. Read git log: Run git log --oneline --no-merges since the specified point
  3. Categorize commits by conventional commit prefixes:
    • Features (feat:, add:, new:)
    • Bug Fixes (fix:, bugfix:)
    • Documentation (docs:)
    • Performance (perf:)
    • Refactoring (refactor:)
    • Other (chore:, ci:, test:, style:, build:)
  4. If no conventional commits found: Analyze commit messages and categorize by intent
  5. Format output:

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.
