writing-plans

writing-plans is a skill for Claude Code from CarbeneAI/Forge. It costs 73 tokens per session (3,753 once invoked), scanned A, original, MIT.

A tool for writing detailed implementation plans for software projects. It breaks work into small tasks and explains the files, code patterns, and integration points involved.

In plain words
What is it for?
It helps plan features, fixes, and development roadmaps with granular tasks, exact file locations, expected results, and verification points.
Why use it?
It gives developers a concrete path through an unfamiliar codebase before they begin making changes.

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

writing-plans 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 7d 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.

Writing Plans

Creates detailed, executable implementation plans that break complex features into granular tasks with exact specifications.

When to Activate This Skill

  • "create implementation plan for X" → Detailed task breakdown
  • "plan this feature" → Step-by-step roadmap
  • "how should I implement Y" → Design + plan
  • "write a plan for Z" → Executable specification
  • Before starting complex implementation → Planning phase

Core Philosophy

Granular Task Sizing: 2-5 Minutes Each

Each task should be completable in 2-5 minutes by a skilled developer. This enables:

  • Clear progress tracking
  • Easy parallelization
  • Minimal context switching
  • Obvious verification points

Audience: Skilled Developers Unfamiliar with Codebase

Write plans assuming implementer:

  • ✅ Knows the programming language and frameworks
  • ✅ Understands software development best practices
  • ❌ Doesn't know this codebase's structure
  • ❌ Hasn't seen the existing code patterns
  • ❌ Doesn't know where files are located

Provide exact file paths, show existing patterns, explain integration points.

Methodology: TDD, DRY, YAGNI

  • TDD (Test-Driven Development): Write test first, implement to make it pass
  • DRY (Don't Repeat Yourself): Reuse existing code, extract common patterns
  • YAGNI (You Ain't Gonna Need It): Only implement what's specified, no extras

Example:

Mandatory Headers

Every plan must include:

# [Feature Name] Implementation Plan

**Created:** 2026-02-03
**Status:** Ready for Implementation
**Estimated Time:** [X tasks × 2-5 min = Y-Z minutes total]

## Goal

[1-2 sentences: What are we building and why?]

## Architecture

[High-level approach: What components, how they interact, data flow]

## Tech Stack

[Languages, frameworks, libraries to use. Must match existing codebase.]

## Prerequisites

[What must exist before starting? Dependencies, setup, access required]

## Tasks

[Detailed task list - see below]

## Verification

[How to verify entire implementation is complete]

## Rollback

[How to undo if needed]

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.

writing-plans is a skill published in the GitHub repository CarbeneAI/Forge (9 stars, last pushed 1mo ago), licensed MIT. It adds 73 tokens to every session and 3,753 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
