create-plan

A rule for turning TODOs or complex features into ordered implementation plans and checklists. It requires researching the codebase first and storing the plan in a Markdown file.

In plain words
What is it for?
Use it to break a TODO into actionable steps and save the resulting checklist under .cursor/memory.
Why use it?
It reduces the risk of starting work without understanding the existing code, requirements, edge cases, or platform constraints.

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.

Create Implementation Plan

Use this rule to generate detailed implementation plans for TODOs, breaking down complex tasks into ordered, actionable steps.

Important Note

Before generate any implementation plan and checklist, follow the steps in the prepare rule to thoroughly research and understand the codebase context. This ensures your implementation aligns with existing patterns and standard of the codebase.

When to use

  • When planning the implementation of a TODO item from a list
  • When breaking down a complex feature into manageable steps
  • When you need a step-by-step checklist approach to solving a problem

Instructions

The following instructions will help you create an implementation plat for a TODO item. Create the folder if it doesn't already exist .cursor/memory to store implementation plants, then follow the following steps and instructions:

  1. First, thoroughly analyze the TODO description to understand:

    • The main goal/purpose of the feature
    • The specific technical requirements
    • Any risks or edge cases mentioned
    • Platform-specific considerations
  2. Create a markdown file in the .cursor/memory/{todo-name}-checklist.md format using the edit_file tool:

    # EXAMPLE COMMAND: Replace {todo-name} with the specific TODO identifier
    edit_file(
      target_file: ".cursor/memory/{todo-name}-checklist.md",
      instructions: "Creating implementation plan checklist file for TODO X",
      code_edit: "---\ncreatedOn: \"2023-06-15T14:30:00-07:00\"\nupdatedOn: \"2023-06-15T14:30:00-07:00\"\n---\n\n# TODO X: [Feature Name] Implementation Checklist\n\n## Background\n..."
    )
    
  3. Always include a YAML frontmatter at the top of the file with the following fields:

    • createdOn: The ISO date time string (with timezone) when the file was first created
    • updatedOn: Initially the same as createdOn, but must be updated by the implementor whenever they make changes
    • Example:
      ---
      createdOn: "2023-06-15T14:30:00-07:00"
      updatedOn: "2023-06-15T14:30:00-07:00"
      ---
      
    • The planner MUST use the current local date time with timezone information when creating the file
    • The implementor MUST update the updatedOn value whenever they modify the file or mark checklist items as complete
    • Here are examples of valid ISO date time strings with timezone information:
      • "2023-06-15T14:30:00-07:00" (Pacific Daylight Time)
      • "2023-06-15T16:30:00-05:00" (Central Daylight Time)
      • "2023-06-15T22:30:00+01:00" (British Summer Time)
      • "2023-06-16T06:30:00+09:00" (Japan Standard Time)

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.

create-plan is a cursor rule published in the GitHub repository zackiles/cursor-config (17 stars, last pushed 1y ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 3,444 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
