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

sts2-llm skills.instructions.md 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

skill 文件与变更记录说明

适用范围:

  • .github/skills/**/SKILL.md
  • knowledge/seed/skill-change-log.jsonl

基本规则

  • organizer 和 player 都可以修改 repo-level skill。
  • 每次 skill 变更都必须同时留下文档记录。
  • skill 变更不能只存在于聊天上下文里。

修改 skill 时的最小要求

每次修改 .github/skills/<skill-name>/SKILL.md 时,必须同时:

  1. 更新对应 skill 文件
  2. 向 knowledge/seed/skill-change-log.jsonl 追加一条记录

建议字段:

  • timestamp
  • actor
  • skill
  • changeSummary
  • reason
  • relatedFiles
  • behaviorChange

何时要同步更新总文档

如果 skill 变更影响以下内容之一,还要同步更新总文档:

  • 推荐入口
  • player / organizer / skill 的职责边界
  • 调试方式
  • live 主路径

优先检查:

  • README.md
  • .github/copilot-instructions.md
  • PROJECT_DESIGN.md
  • AGENTS.md

工作方式

  • skill 应尽量保持短、小、明确
  • skill 负责塑造行为,不负责堆新的包装层
  • 如果一个 skill 只是重复 README 结论而没有明确触发条件,应考虑合并或删除

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.
