plan-writing

plan-writing is a skill for Claude Code from xenitV1/Antigravity-Workflows. 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 a short sequence of small, ordered actions with clear checks for completion.

In plain words
What is it for?
Use it when planning a feature, refactor, or other multi-step change that needs an actionable plan saved in the project root.
Why use it?
It makes multi-step work easier to follow and verify, while keeping dependencies and the final check visible.

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

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.
