What it does
Skill Invocation Router is an agent skill from fancyboi999/ai-engineering-from-scratch-zh. 为 Agent Skill 目录设计并测试显式人工、隐式模型或 agent、程序化应用、有界 skill 组合和 harness 激活策略。
Its SKILL.md is about 220 tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files, including scripts, reference files and assets (for example `assets/host-policy.json`, `references/invocation-model.md` and `scripts/simulate_invocation.py`).
It sits in AI & LLM Engineering. It works with Python. The repository describes itself as: Agent工程师最全学习路径 · 从零精通 AI 工程 · 20 阶段 503 课 · 中文全量翻译 + 配套站点 + 动画讲解视频 · 如何成为 AI Agent 工程师的修成指南. The licence is MIT.
When your agent uses it

8 steps, taken from the first numbered list in SKILL.md.
- 阅读 references/invocation-model.md，并归类请求通道。
- 查看 assets/host-policy.json；它是适配器配置示例，不是可移植标准。

- 对人工、应用、skill 或 harness 请求，要求精确的已发现名称和该通道的 allowlist。
- 对 skill 调用者，还要求调用者身份、无环目标和有界组合深度。
- 对模型或自治 agent 请求，排除 actor 或已识别宿主扩展使其不具资格的候选项。
- 只为其余描述打分；选最强的合格匹配，若没有候选项过阈值则弃权。
- 返回包含 adapter、通道、分数和策略原因的 JSON 决策。
What it can do on your machine
Read from SKILL.md and the folder at commit fb127e2. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships 1 file in scripts/ (Python), which the agent can run.
Shell commands in SKILL.md call:
python3
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Skill Invocation Router loads about 215 tokens when it runs, and up to ~520 if it reads all its reference files. Until then it costs about 24 tokens; SKILL.md has 62 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.
