Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

description: Create detailed implementation plans with bite-sized tasks for engineers with zero codebase context
when_to_use: when design is complete and you need detailed implementation tasks for engineers with zero codebase context
version: 2.1.0

# Writing Plans
## Overview
Write comprehensive implementation plans assuming the engineer has zero context for our codebase and questionable taste. Document everything they need to know: which files to touch for each task, code, testing, docs they might need to check, how to test it. Give them the whole plan as bite-sized tasks. DRY. YAGNI. TDD. Frequent commits.
Assume they are a skilled developer, but know almost nothing about our toolset or problem domain. Assume they don't know good test design very well.
**Announce at start:** "I'm using the Writing Plans skill to create the implementation plan."
**Context:** This should be run in a dedicated worktree (created by brainstorming skill).

How to install
mdr add sigilagent/sigil/writing-plans@sha256:8b2ecf1bf8515555The line at the top of this page pins the label git:20260724.0564d2d, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
