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

release-notes 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 3d 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

Release Notes

Use this skill when drafting release notes, changelog entries, upgrade notes, or release summaries.

Inputs

  • Commit log, pull request list, diff, issue list, or milestone notes
  • Target audience: users, developers, operators, or internal stakeholders
  • Version number, release date, and compatibility constraints if known

Steps

  1. Group changes by user impact: Added, Changed, Fixed, Security, Deprecated, Removed, Performance, Documentation.
  2. Translate implementation details into outcomes without hiding important technical changes.
  3. Identify breaking changes, migration steps, config changes, and operational actions.
  4. Call out security fixes without exposing exploit details.
  5. Remove duplicates and merge related items.
  6. Keep known issues and follow-up work separate from shipped changes.

Output

Return:

  • Release summary
  • Categorized changelog
  • Upgrade or migration notes
  • Known issues
  • Verification or rollout notes when useful

Guidelines

  • Be accurate about what shipped.
  • Avoid vague phrases like "various improvements."
  • Preserve version and date details exactly when provided.

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.
