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 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.

What it actually says

Generate a user-facing changelog grouped into Added / Changed / Fixed sections.

Recent git history: !{git log --oneline -30 2>/dev/null || echo "(no git history available)"}

Recent tags: !{git tag --sort=-creatordate 2>/dev/null | head -5 || echo "(no tags)"}

Scope: $ARGUMENTS


Steps:

  1. If Scope is non-empty (e.g. a git ref range like v1.2.0..HEAD or a target version tag), run git log --oneline <scope> to get the relevant commits; otherwise use the recent history shown above.
  2. Group commits into Added, Changed, and Fixed — skip merge commits and CI/chore noise.
  3. Write clean, user-facing bullet points — rephrase commit messages for clarity rather than copying them verbatim.
  4. Output as Markdown with a version heading if a version was specified.
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.
