agent-routing

agent-routing is a cursor rule for Cursor from YuDefine/nuxt-supabase-starter. It costs 16,087 tokens per session, scanned A, original, MIT.

A rulebook for deciding when coding work should be handed to another agent and which agent should receive it. An agent is a software worker that can inspect files, run tools, and make changes.

In plain words
What is it for?
Use it to decide whether to delegate work, select a destination agent, and follow required routing and handoff procedures.
Why use it?
It keeps small or sensitive tasks with the main agent while routing broad scans, independent long-running work, or isolated changes when another runtime is a better fit.

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

agent-routing 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 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.

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.

Agent Routing

核心命題:當工作交給另一個 runtime + model 組合的成本/品質明顯更好時,必須 handoff 而不是硬幹。但派工的預設是不派——先過 § 派不派,命中外派條件才進 Routing Table。本規則優先於個別 skill 內嵌的工具呼叫指示。

本檔是 routing 主規則(每 session 必載入)。派工模板、Watch Protocol、Plan-first / Git baseline、Runtime Gate 在 agent-routing.pi-watch-protocol.md(下稱 reference)。

決定要派 pi 之後、送出 dispatch 之前,MUST 先 Read reference 的 § Pi 派工的標準流程。 reference 的 paths: 綁的是 spectra / screenshot 情境,「單純要派 pi」的 session 不會自動載入它——靠 auto-load 會讀不到(成因與實測見 docs/rule-rationale/agent-routing.md)。

派不派(先於派給誰)

主線自己做是預設。違反字面就是違反精神——「反正派了比較快」「一件一個 agent 比較整齊」都不算遵守。下面的 Routing Table 決定派給誰,本節決定派不派:講不出命中哪一條外派條件,就是主線自己做。

外派條件(命中任一才派):

  • 寬掃——要讀 5 個以上檔案或整棵目錄樹才答得出的問題。派 scout 回結構化事實表(檔名 / 行號 / 現值 / 判準命中與否),原文不進主線
  • 有份量的獨立平行軌——兩條以上彼此不讀對方產出的工作,且每一條都要 10+ tool call 才做得完
  • 長時間 background job——跑得久且主線不必盯著(build / 大量 test / 長 migration)
  • 需要隔離環境——worktree 平行改動、會互相踩檔或搶 port 的工作

不外派(命中就自己做,即使同時有好幾條):少量工具即可結束;路徑已知的少量讀取;規約 / 契約 / 對外文件的定稿措辭(會原樣成為交付物的最終文字);UI view 實作與視覺判讀 / Design Review(component / page / view / layout / styling —— 實作與品質判定都留主線 Opus,NEVER 派 Pi 任一 model、NEVER 派 Claude subagent);需要 claude.ai-connected MCP、且 ntn CLI 做不到 的工作(Notion 走 〔notion-ops〕,不在此列);安全敏感或不可逆的動作(憑證 / 刪檔 / force push / 對外發佈);複驗自己剛做完的東西(判準見 [[checker-subagent]] § 過度派)。

具名 threshold 優先於上段的 generic「少量」判準:同一 prompt segment 準備執行第 3 個高信心 readonly Bash、第 5 個 distinct textual Read,或第一次 Read 501+ 行文字檔時,PreToolUse gate 會建立 pending decision。主線 MUST 以 decision-linked dispatch(exact trigger 走 luna low;更具體工作可走共用 policy 驗證過的 concrete Pi row)、structured waiver,或 dispatcher exit 3/4 後的 matching fallback authorization receipt 結案;完整命令與狀態轉移見 reference § Routing threshold gate。

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-routing is a cursor rule published in the GitHub repository YuDefine/nuxt-supabase-starter (45 stars, last pushed yesterday), licensed MIT. It adds 16,087 tokens to every session, about $0.0804 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.
