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 | $0.08382 | $0.08382 |
| Opus 5 | $0.04191 | $0.04191 |
| Sonnet 5 | $0.01676 | $0.01676 |
| Haiku 4.5 | $0.00838 | $0.00838 |
Grade A, and why
agent-self-verification scanned grade A with 1 finding 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 yesterday.
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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.
- 「curl 打過了,302 / 200,登入流程正常」「cookie jar 有存到,session 沒問題」(對**帶登入態**的流程,curl 的狀態碼不是證據;per 下方 MUST 16) How it starts
The opening of the file, as written. The whole thing — 240 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Agent Self-Verification
核心命題:agent 完成 evidence 收集是預設職責,禁止把可自動化的驗證(dev login / 截圖 / API round-trip / test / DB query)踢回 user。User handoff 是最後手段 — 必須主線跑完已知 fallback chain 仍失敗才行。
此規則優先於個別 skill 內嵌的「請 user 確認」捷徑指示;every session always-load。
Browser 載體(Cursor vs 非 Cursor)
開網頁/截圖/登入頁之前 MUST 先讀 [[agent-routing]] § Cursor 環境的 browser 載體——環境 predicate、該用哪個載體、以及全部 NEVER 都在那一節。不要寫死 agent-browser。 本檔 NEVER 複寫該節內文:L69 同型複本曾寫成相反方向、隨投影散到全 fleet 十一個 consumer。
證據鑑別力(先於下方每一條 NEVER / MUST)
驗收引用的證據 E,MUST 能回答「若被驗命題為假,E 會長什麼不一樣?」——答不出或答案是「一樣」→ E 不是證據,換一個在兩個世界會分岔的觀測。status code、exit code、「檔案存在」、工具自我宣告、來自常數宣告而非量測的數字,預設視為未分岔訊號。MUST 11 / 16 / 19 是本條的三個實例;新形態回到上面那句自判。降級路徑觸發時 MUST loud(warning / health degraded),讓假世界主動分岔。實證三例見 [[pitfall-empty-state-screenshot-has-no-discriminating-power]]。
摘要值(hash / 行數 / 檔案數 / diff 大小)同屬未分岔訊號:sha256sum / md5sum / wc -l 這類全域函式對空輸入不報錯、照樣回一個外觀正常的值,於是「上游命令死掉」與「內容真的是空的」在它的輸出裡完全相同。每一次拿 hash 或 count 當證據,MUST 先驗產生它的那條 pipeline 的 exit code 與非空性;NEVER 從摘要值反推成因。逐字反開脫:「hash 有值代表命令成功了」——[ -n "$(printf '' | sha256sum)" ] 恆真(空輸入的 sha256 就是 e3b0c442…),那道 guard 讀起來在防空值、實際永遠通過。實證見 [[pitfall-hash-of-empty-stdout-collapses-distinct-causes]]。
否定命題 MUST 先做陽性對照(先於下方每一條具名處方)
結論形式是「沒有 X」時,MUST 先對量測工具做一次陽性對照——用一個已知存在的目標跑同一條指令,確認它回得出非空。回空就是工具壞了,不是「沒有 X」。 對照沒跑,那個「沒有」不是證據,NEVER 拿它當任何動作的前提(起 publish、判 lane 空、判沒人在跑、判無違規)。
這條排在所有具名處方之前,不與它們並列,理由只有一條:它不要求你事先知道那個特定的坑。 具名處方(find 加 -L、比對 exe 不比對 comm、進程列表不加 | head -N)擋的是已知的坑,而會出事的每一次,都是不知道的那一次。陽性對照擋的是「這個工具現在到底活著沒有」——後者不成立時,前者全部沒有意義。
逐字反開脫:「指令跑完了、沒報錯、回空,所以確實沒有」——空輸出與工具壞掉在 stdout 上完全同形,而否定命題只能用「找不到」來證,所以這一整類對假陽性與假陰性都零抵抗。假訊號不是讓你少知道一件事,是讓你知道一件相反的事。
誠實邊界:陽性對照證的是工具活著,不是 pattern 寫對——它擋不住「工具對目標 A 有效、對目標 B 無效」。NEVER 把對照通過讀成「這次的查詢是對的」。
判「某個程式在不在跑」時 MUST 貼 [[process-probe]] 的 is-running.sh,NEVER 現場自組 pgrep / ps | grep:pgrep -f 比對整條 cmdline,量的是「有沒有人提到這個字」;該腳本內建兩段對照並把「沒有在跑」(exit 1)與「量不出來」(exit 2)分成不同 exit code。裸 pgrep 把這兩個結論折成同一個空輸出。
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.

agent-self-verification is a cursor rule published in the GitHub repository YuDefine/nuxt-supabase-starter (45 stars, last pushed today), licensed MIT. It adds 8,382 tokens to every session, about $0.0419 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
