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

release-blog-writer 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 6d 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.

Release blog writer

Purpose

Use this skill to write release blogs that feel like product communication, not raw changelog output. The blog may be written in English, Chinese, or another user-requested language, but these instructions stay language-agnostic and project-agnostic.

Core writing rules

  • Follow the user's requested language and the style of existing release blogs for the same product.
  • Use previous major or minor release posts as the primary style reference when available.
  • Prefer clear user value over implementation trivia.
  • Avoid turning the blog into a complete changelog.

Use the project's existing blog metadata and component conventions. If the product has neighboring release posts, mirror their frontmatter, author block, date format, title style, and navigation pattern.

Section writing

Each feature section should usually follow this pattern:

  • Describe the change clearly so readers understand its background, purpose, use cases, and user-facing benefits such as performance gains.
  • Avoid exhaustive API lists; select the key APIs or behaviors readers need, and when useful, use one precise code or configuration example to make the change clear at a glance.

Headings

  • Use sentence case for titles and headings.
  • Keep headings short and specific.
  • Keep anchors stable and readable.
    • If the website is built with Rspress, use the Rspress anchor syntax, such as \{#foo-bar}.
    • For multilingual posts, treat the English post as the source of truth for section anchors. Matching headings in other languages should resolve to the same final anchor as the English heading, adding \{#anchor-id} when their generated anchor would differ.
    • Default English anchors are generated by lowercasing the heading, removing punctuation, replacing whitespace with hyphens, and appending numeric suffixes for duplicates. If the English heading is long or the generated anchor is not stable enough, choose a short semantic custom anchor and apply it to every language version.
    • Do not add a custom anchor when it is identical to the default generated anchor.

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.
