Generate numbered repo spec folders with clear requirements, implementation plans, and task lists for non-trivial project work.
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.
What the file says
# Spec Writer Skill ## Intent Use this skill to turn a rough repo change, feature idea, cleanup effort, or migration into a numbered spec folder with practical planning documents. The goal is to create a working spec package that another engineer can pick up and execute without guessing what the work means. ## Use When - The user wants a new spec for a repo change, feature, refactor, migration, or workflow - A project needs structured `requirements.md`, `plan.md`, and `tasks.md` documents - The repo already uses numbered spec folders and new work should follow that pattern - The request is large enough that ad hoc notes would be too loose ## Do Not Use When - The change is tiny and does not need formal planning - The repo has no spec workflow and the user only wants direct implementation - The user wants a README, assessment, or changelog instead of an execution spec - The available context is too thin to produce honest requirements and next steps ## Workflow 1. Read the repo context first. 2. Confirm where specs live and how numbering works. 3. Pick the next available spec number unless the user provided one. …

How to install
mdr add mickpletcher/ai-skills/spec-writer@sha256:3b8728f16a9d752cThe line at the top of this page pins the label v1.1.0, 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.
