Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00058 | $0.01098 |
| Opus 5 | $0.00029 | $0.00549 |
| Sonnet 5 | $0.00012 | $0.00220 |
| Haiku 4.5 | $0.00006 | $0.00110 |
Grade A, and why
maigo-self-check 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 9d 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.
How it starts
The opening of the file, as written. The whole thing — 76 lines — stays where its author put it; the contents beside it link to each section on GitHub.

觸發條件
diff 動到以下任一路徑時啟用本 skill：
agents/commands/skills/（含SKILL.md與references/子目錄）mkdocs.ymldocs/
純動 Python source（hooks/、scripts/、tests/）→ 只跑 pytest，不觸發本 skill。
兩者都動（如同時改 scripts/ 與 docs/）→ pytest + 本 skill 兩條都跑。
驗證指令
uv run python scripts/validate_plugin.py
uv run mkdocs build --strict
為什麼都用專案環境：
uv run python scripts/validate_plugin.py— validator 使用專案宣告的 Python 版本；不受 host 上較舊的系統python3影響。uv run mkdocs build --strict— mkdocs 是 venv 工具（在pyproject.toml的 docs dependency 裡）。
這兩條抓的是 pytest 抓不到的東西
| 問題類型 | 被哪條抓到 |
|---|---|
include shim 缺失（docs/skills/<name>.md 沒建） |
validate_plugin.py |
frontmatter name 對不上目錄名 |
validate_plugin.py |
skill catalog（docs/reference/skills.md）漏列 |
validate_plugin.py |
| mermaid 相依圖缺 skill 節點 | validate_plugin.py |
| 相對 link 在 include-markdown rewrite 後炸 strict-mode | mkdocs build --strict |
| docs nav 指到不存在的 page | mkdocs build --strict |
| command 檔缺「掛名」角色台詞（引號旁邊沒有角色 emoji / 名字） | validate_plugin.py |
CLAUDE.md / AGENTS.md 的共同驗證慣例漂移 |
validate_plugin.py |
pytest 測的是 Python 行為；上述問題都在 plugin 結構層——pytest 對它們是盲的。
新增 / 改 commands/*.md 時，至少保留一段掛名角色台詞（MyGO!!!!! 濃度慣例）——單純
「有「」引號」不算數，旁邊要看得到角色 emoji / 名字（或是 > 「...」 blockquote 標題引言），
不能只是 UI/error 訊息引號。機器兜底由 validate_plugin.py 的
check_command_persona_quotes 檢查，不必自己記著掃。
改 references/*.md 時：跟 SKILL.md 摘要同步
幫某個 skill 的 references/*.md 加新內容時，兩件事一起做，缺一都算沒改完：
- 改之前先看該 reference 檔開頭宣告的範圍（例如「Read this file when ...」）是否覆蓋新主題。 題材對不上就不要硬塞——擴大宣告範圍，或改放進更貼切的位置（往往是 SKILL.md 本體裡已經在談同主題的段落）。
- 改之後同步 SKILL.md 本體對這份 reference 檔案的摘要（列出的條數、bullet 清單）——SKILL.md 是永遠會被載入的主體，reference 檔是 on-demand；摘要沒同步，新內容等於沒人看得到。
為什麼：/maigo:crystallize 一次批次畢業多筆記憶時踩過兩次——references/*.md 加了新內容，
但 SKILL.md 本體的條數摘要（如「Three cross-cutting patterns」）沒跟著改成新的數字。這條檢查
不限 crystallize；/maigo:quick、/maigo:go 只要動到 skills/ 都算。
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.

maigo-self-check is a skill published in the GitHub repository Lee-W/maigo (14 stars, last pushed today), licensed MIT. It adds 58 tokens to every session and 1,098 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 2026-08-30.
