plan-writing

plan-writing is a skill for Claude Code from ashrafmusa/agenticana. It costs 31 tokens per session (1,019 once invoked), scanned A, a copy of plan-writing, MIT.

A method for breaking a software task into short, ordered steps with clear checks for completion. It also identifies dependencies and puts verification at the end.

In plain words
What is it for?
Use it to plan implementations, refactors, or other multi-step engineering tasks, with the plan saved in the project root.
Why use it?
It turns a broad feature or refactoring request into manageable work that can be checked as it progresses.

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-writing scanned grade A with 1 finding 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 8d 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.

Overview

This skill provides a framework for breaking down work into clear, actionable tasks with verification criteria.

Task Breakdown Principles

1. Small, Focused Tasks

  • Each task should take 2-5 minutes
  • One clear outcome per task
  • Independently verifiable

2. Clear Verification

  • How do you know it's done?
  • What can you check/test?
  • What's the expected output?

3. Logical Ordering

  • Dependencies identified
  • Parallel work where possible
  • Critical path highlighted
  • Phase X: Verification is always LAST

4. Dynamic Naming in Project Root

  • Plan files are saved as {task-slug}.md in the PROJECT ROOT
  • Name derived from task (e.g., "add auth" → auth-feature.md)
  • NEVER inside .claude/, docs/, or temp folders

Planning Principles (NOT Templates!)

🔴 NO fixed templates. Each plan is UNIQUE to the task.

Principle 1: Keep It SHORT

❌ Wrong ✅ Right
50 tasks with sub-sub-tasks 5-10 clear tasks max
Every micro-step listed Only actionable items
Verbose descriptions One-line per task

Rule: If plan is longer than 1 page, it's too long. Simplify.


Principle 2: Be SPECIFIC, Not Generic

❌ Wrong ✅ Right
"Set up project" "Run npx create-next-app"
"Add authentication" "Install next-auth, create /api/auth/[...nextauth].ts"
"Style the UI" "Add Tailwind classes to Header.tsx"

Rule: Each task should have a clear, verifiable outcome.


Principle 3: Dynamic Content Based on Project Type

For NEW PROJECT:

  • What tech stack? (decide first)
  • What's the MVP? (minimal features)
  • What's the file structure?

For FEATURE ADDITION:

  • Which files are affected?
  • What dependencies needed?
  • How to verify it works?

For BUG FIX:

  • What's the root cause?
  • What file/line to change?
  • How to test the fix?

Principle 4: Scripts Are Project-Specific
