plan

plan is a command for Claude Code from rex/mcp-rancher. It costs 15 tokens per session (179 once invoked), scanned A, original, MIT.

A planning command that breaks a software feature into smaller implementation slices and creates supporting specification files. It gathers research from affected parts of the codebase before writing the plan.

In plain words
What is it for?
Use it to plan a feature, create or update its specification and task files, record the first active slice in TASK_STATE.md, and summarize expected work and risks.
Why use it?
It gives a feature a documented scope, sequence, and risk review before coding begins, while explicitly leaving implementation for later.

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

plan 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 5d 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.

What it actually says

Plan: $ARGUMENTS

  1. Spawn planner subagent with the feature + AGENTS.md context.
  2. Before finalizing, spawn 2–3 research-agent in PARALLEL for affected modules.
  3. Pass findings back to planner.
  4. planner writes/updates specs/<slug>/spec.md, design.md, plan.md, tasks.md.
  5. planner updates TASK_STATE.md with the first active slice.
  6. Summary: slice count, estimated LOC, risks.

Do NOT implement. This command only plans.

Changes

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.
