Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00065 | $0.00684 |
| Opus 5 | $0.00032 | $0.00342 |
| Sonnet 5 | $0.00013 | $0.00137 |
| Haiku 4.5 | $0.00006 | $0.00068 |
Grade A, and why
skill-authoring-gate scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured today.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
Skill 编写门禁
开始编辑前
- 加载
~/.agents/skills/writing-for-agents/SKILL.md；涉及 frontmatter、触发方式或 router 时，继续加载同目录的SKILL-MECHANICS.md。 - 加载
~/.agents/skills/.system/skill-creator/SKILL.md；它是系统 skill，不是目标仓库的 skill。不要把"系统可能自动选中 Skill Creator"当作门禁，规则本身必须保证被执行。 - 先读取目标
SKILL.md和agents/openai.yaml（如果存在），按实际工作流判断默认触发类型，再修改内容与配置。 SKILL.mdfrontmatter 的description是触发规则，不是功能介绍。只写用户请求或任务形状何时匹配；能力、角色、实现和本轮改动写进正文。改行为时默认保持description不变，除非触发条件本身变了。
分类与配置一致
- 流程类 Skill（规划、审查、复盘、治理、发布、迁移、编排，或带审批、用户决策、明显副作用的多步流程）：默认仅显式触发，同时设置
policy.allow_implicit_invocation: false、frontmatterdisable-model-invocation: true和triggers: [user]（Devin 的等效标记），三层都必须存在。用户通过宿主原生语法显式调用：Codex、Pi、OpenCode 用$skill-name，Kimi 用/skill:skill-name，Devin 用/skill-name。 - 被动型 Skill（低风险的格式化、生成、查询或验证能力）：默认允许隐式触发，设置
policy.allow_implicit_invocation: true，且不得遗留disable-model-invocation: true。 - 无法明确分类或混合型 Skill：采用流程类的保守默认值；用户要改成允许隐式触发时，必须明确提出并说明风险与影响。
交付前
- 运行 Skill validator、YAML 解析和
git diff --check；如果 validator 尚不识别兼容性的disable-model-invocation或triggers字段，记录该工具限制并补做 frontmatter 结构检查，不得为了让 validator 通过而删除流程类 Skill 的禁用标记。 - 核对
description仍是触发匹配，没有被改成能力说明书。 - 向用户报告：分类、默认策略、判断依据、配置位置，以及显式触发 Skill 的
$skill-name用法；用户明确意图与默认分类冲突时，以用户意图为准并说明。
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

skill-authoring-gate is a skill published in the GitHub repository hxy91819/mason-skills (2 stars, last pushed today), licensed MIT. It adds 65 tokens to every session and 684 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-04.
