octopus: Instructions file for Claude Code

CLAUDE.md

octopus CLAUDE.md is an instructions file for Claude Code from SatoruoGojoo/octopus. It costs 3,497 tokens per session, scanned A, original, MIT.

A set of instructions for Octopus, a Claude Code plugin made from Markdown agents and slash commands. It runs work across other software projects and uses OpenSpec, a format for recording current system behavior and proposed changes.

In plain words
What is it for?
Use it when changing Octopus agents, commands, documentation, hooks, or version information. It helps keep the design documents, implementation, tests, and release records aligned.
Why use it?
It gives developers one source of truth for how the plugin should work and in what order to update its design and implementation. It also defines checks needed before releasing a new version.

Instructions file for Claude Code

Written for Claude Code: ${CLAUDE_PLUGIN_ROOT} variable. Also seen: mentions CLAUDE.md; mentions subagents; mentions Claude Code.

This is SatoruoGojoo/octopus's own configuration. It tells Claude Code how to work on octopus itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything octopus configures →

Runs only inside a plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else, and the catalogue could not identify which plugin ships it.

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

octopus CLAUDE.md 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 6d 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.

這個 repo 是什麼

Octopus 是一個 Claude Code plugin(不是應用程式、沒有 build / runtime)。它本身就是 prompt 工程的成品:一組 markdown 定義的 agent 與 slash command,安裝後在「別的專案」裡用 /octopus:<指令> 驅動一個後端工作流 harness。唯一的可執行程式碼是兩支 hook,附回歸測試——專案根執行 node --test

世界觀:一顆頭(使用者=TPM)+ 七隻腳(專家 agent)。TPM 只做三件不可替代的事——定義意圖、拍板取捨、驗收放行;agent 做其餘的實作、審查、考古、除錯。設計公理:harness 品質取決於三個 TPM 介面(需求進口、決策呈現、驗收出口)的品質,不是 agent 數量。

v0.5 起 spec 格式全面採用 OpenSpec(Fission-AI/OpenSpec):目標 repo 的 openspec/specs/<domain>/ 是「系統現況」活文件,每筆工作是 openspec/changes/<name>/ 一筆 change;openspec CLI 是管線前置依賴(validate/archive)。

權威來源與修改順序

  • docs/Octopus-功能文件.md 是唯一權威設計文件。 所有 agent/command 行為都從它推導。
  • 改行為時:先改設計文件 → 再改 agents/commands/。實作與設計文件衝突時,以設計文件為準,回去修訂後再動實作。
  • 改完插件檔案後,在使用端的 Claude Code 對話執行 /reload-plugins 才會生效。

版更收尾紀律(版號提升前必跑)

  1. 本輪對話的設計決定全部落檔(設計文件→實作),不留在對話裡
  2. 反向對帳:本次動過的章節,設計文件宣稱的產物/行為 grep 驗證實作有對應
  3. 砍掉的東西補進 docs/退場紀錄.md(含理由)
  4. 三處同步plugin.json 版號、設計文件版本標頭、本檔相關摘要

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.
