plan

A structured planning command for breaking complex development work into smaller tasks and recording them in a todo list.

In plain words
What is it for?
Use it to plan features, bug fixes, tests, documentation, builds, or deployments after reviewing the existing codebase.
Why use it?
It turns a broad coding request into ordered steps, including implementation and checks, so important work is less likely to be missed.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 3d 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.

Origin

This is a copy

100% identical to plan — 0 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

Create a comprehensive task plan for the given development work. Break down complex tasks into manageable, actionable steps.

Planning Process

  1. Analysis Phase

    • Use Read, Grep, and Glob tools to understand the current codebase
    • Identify existing patterns, conventions, and dependencies
    • Check git status to understand current state
  2. Task Breakdown

    • Decompose the main objective into specific, actionable tasks
    • Each task should be completable within a reasonable timeframe
    • Include both implementation and verification steps
  3. Create Todo List

    • Use TodoWrite tool to create a structured task list
    • Set all tasks to "pending" status initially
    • Include both content (imperative form) and activeForm (present continuous)
    • Order tasks by logical dependency and priority
  4. Task Categorization

    • Implementation tasks (new features, bug fixes)
    • Testing and verification tasks
    • Documentation updates (if required)
    • Build and deployment tasks

Task Planning Guidelines

  • Make tasks specific and measurable
  • Include prerequisite checks where needed
  • Add validation steps after implementation
  • Consider potential blockers and alternatives
  • Ensure each task has clear completion criteria

Example Task Structure

For each task in the todo list:

  • content: "Implement user authentication middleware"
  • activeForm: "Implementing user authentication middleware"
  • status: "pending"

Always start with research and analysis tasks before moving to implementation.

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.

plan is a command published in the GitHub repository WildChildForLife/lantern (22 stars, last pushed 8d ago), licensed MIT. It adds 9 tokens to every session and 349 once invoked, about $0.0000 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to plan, differing in 0 lines, and is treated as a copy.
