plan

A planning command that breaks a software task into small, ordered pieces with acceptance criteria and checks. It reads the project specification and relevant code before producing the plan.

In plain words
What is it for?
Use it to create a reviewed plan in `tasks/plan.md` and a task list in `tasks/todo.md`, without changing code.
Why use it?
It makes dependencies and completion conditions explicit before implementation begins, reducing unclear or incomplete work.

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 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.

Origin

This is a copy

88% identical to plan — 2 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

Invoke the agent-skills:planning-and-task-breakdown skill.

Read the existing spec (SPEC.md or equivalent) and the relevant codebase sections. Then:

  1. Enter plan mode — read only, no code changes
  2. Identify the dependency graph between components
  3. Slice work vertically (one complete path per task, not horizontal layers)
  4. Write tasks with acceptance criteria and verification steps
  5. Add checkpoints between phases
  6. Present the plan for human review

Save the plan to tasks/plan.md and task list to tasks/todo.md.

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.
