takomi-codex

takomi-codex is a skill for Claude Code, Codex from J-StaR-Films-Studios/VibeCode-Protocol-Suite. It costs 38 tokens per session (1,574 once invoked), scanned A, original, ISC.

A lifecycle-management workflow for coordinating work inside Codex. It can detect the available runtime, keep plans in Markdown roadbooks, and support delegation when the user explicitly agrees.

In plain words
What is it for?
Use it to plan, coordinate, and delegate larger Codex tasks across different runtimes.
Why use it?
It helps organise multi-step agent work and makes the plan and delegation decisions visible.

    Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.
    Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.

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

takomi-codex 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 8d 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.

Takomi Codex

Takomi Codex is the Codex-native adapter for the Takomi protocol. Use it when the user asks for Takomi, orchestration, roadbooks, Genesis/Design/Build lifecycle work, policy-aware execution, Pi/Takomi runtime inspection, or delegated task coordination.

Operating Principle

Choose the smallest execution mode that can do the work well, then delegate by default once Takomi decomposes the work:

  1. Direct Codex work for small, local, one-shot tasks.
  2. Planning mode for unclear or UI/UX-heavy work.
  3. Markdown roadbook orchestration for broad multi-step work.
  4. Delegation-first orchestration when Takomi creates subtasks, roadbook tasks, or an orchestration session.

Do not create a board, launch a harness, or spawn threads for trivial edits.

The main Codex agent remains the orchestrator for decomposed work. It owns context intake, task packets, board updates, synthesis, verification, and final user handoff. It should not act as the primary implementer by default after decomposition begins.

User override is explicit: if the user says "do it yourself", "no subagents", "no new threads", or equivalent, the main agent may execute directly while still keeping any existing roadbook current.

Required Context Pass

Before complex code or orchestration, inspect the project:

  • docs/features/
  • docs/project_requirements.md
  • docs/Project_Requirements.md
  • local .pi/ if relevant
  • Takomi feature docs related to the request

For major features, create or update a feature markdown file before implementation.

Runtime Detection

Use scripts/takomi-detect.ps1 when runtime state affects the answer.

Detection priority:

  1. Project-local .pi/.
  2. User/global ~/.pi/agent/ and ~/.agents/skills/.
  3. CLI availability for takomi and pi.
  4. Plugin-bundled guidance.

Global/user paths are read-only unless the user explicitly approves a write.

Policy Loading

Use scripts/takomi-policy.ps1 when model, subagent, review, or lifecycle routing matters.

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.
