create-plan

A command that creates a PLANS.md file in a project’s main folder to organise planned work. It can use details from a GitHub issue, a service for tracking software tasks and discussions.

In plain words
What is it for?
Use it to turn a project goal or GitHub issue into a structured execution plan with tasks, deliverables, and acceptance criteria.
Why use it?
It gives a project one shared place for goals, scope, milestones, progress, discoveries, and decisions. This reduces the need to reconstruct the plan from scattered notes and issue comments.

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.

Made for: Claude Code.

Per session 11 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 428 The whole file, excluding the scripts and references it only reads on demand.

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

create-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 2d 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

Task

Create a comprehensive PLANS.md file in the project root directory to track project execution.

Input Handling

If the arguments contain a GitHub issue reference:

  1. Extract the issue number from arguments (format: #123, 123, or GitHub URL)
  2. Use gh issue view <issue-number> to fetch the issue details
  3. Understand the requirements and context from the issue
  4. Search the codebase for relevant files if needed
  5. Use the issue information to populate the PLANS.md sections

Structure

The PLANS.md should include these sections:

  1. Purpose / Big Picture

    • Project goal summary
    • User benefits
    • Expected user-visible behavior
  2. Initial Requirements & Scope

    • High-level requirements
    • Key features list
    • In-scope vs. out-of-scope items
  3. Milestones & Deliverables

    • Work phases breakdown
    • Specific deliverables
    • Acceptance criteria
  4. Progress

    • Checkbox task list for granular tracking
    • Completion status
    • Progress dates
  5. Surprises & Discoveries

    • Unexpected learnings
    • Technical challenges
    • New insights
  6. Decision Log

    • Key decisions with dates
    • Reasoning and context
    • Supporting references
  7. Outcomes & Retrospectives

    • Milestone results
    • Lessons learned
    • What went well / could improve

Guidelines

  • Start with information gathered from the current project context
  • Use the user's input to understand the project scope
  • Keep it concise but comprehensive
  • Format as a living document that can evolve
  • Use markdown checkboxes - [ ] for trackable tasks

Arguments

Accepts:

  • Project description or context (free text)
  • GitHub issue number (e.g., 123 or #123)
  • GitHub issue URL

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.
