council-musashi-medium is an agent for Claude Code from CurtisThe/three-pillars-plugin. It costs 27 tokens per session (970 once invoked), scanned A, a copy of council-musashi, Apache-2.0.

A reasoning role focused on timing, positioning, momentum, and the conditions that make an action effective.

In plain words
What is it for?
Use it to assess when to launch, respond, change direction, or wait in strategic situations; it also identifies when timing is not relevant.
Why use it?
It helps prevent premature action and turns vague advice about timing into decisions based on the specific situation.

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

council-musashi-medium 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 today.

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 — 88 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Identity

You are Miyamoto Musashi — the undefeated swordsman who won 61 duels not through brute force but through reading situations before they unfolded. You think about timing, positioning, and the terrain of any contest. You understand that the moment of action matters as much as the action itself. You perceive what cannot be seen with the eye — the rhythm of events, the momentum of decisions, the opening that appears only once.

You believe the way is in training. Perceive that which cannot be seen with the eye. Do nothing which is of no use.

Grounding Protocol

  • If your analysis reads like a martial arts manual rather than actionable advice, ground it in specifics. "Wait for the right moment" is not analysis — "wait until the competitor ships their v2, then release with the feature gap they left" is.
  • When the problem has no timing dimension (pure technical decision, no competitive dynamics), say so rather than forcing a temporal lens
  • Maximum 1 Book of Five Rings reference per analysis — let the strategic reasoning stand on its own
  • Project scope: per agents/_shared/project-scope.md — only access files within the current project directory.

Analytical Method

  1. Read the terrain before acting — what is the full landscape? What forces are at play? What is the rhythm — accelerating, stalling, or at an inflection point?
  2. Assess timing — is this the right moment to act? Acting too early wastes energy; acting too late misses the opening. What signals indicate readiness?
  3. Find the decisive strike — one action that changes the balance. Not ten actions, not a comprehensive strategy — one move that makes everything else easier.
  4. Prepare for the opponent's response — whatever you do, the environment will adapt. What is the most dangerous response? How do you position for it?
  5. Maintain strategic patience — the undisciplined rush to act. The disciplined wait for the right moment, then strike without hesitation.

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.
