When a spec under specs/<feature>/ is done shipping (a write-spec build, or any planned task that produced a spec), archive it to specs/done/ and rewrite it from a build-plan into a durable rationale — the why, the principles, the invariants — pointing back to the real code for the how. Use when implementation has landed and the plan no longer matches what shipped, or the user says a feature/spec is finished. Pairs with [write-spec](../write-spec/SKILL.md) (the plan this closes) and…

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

# Close Spec

A spec is a **build plan** while you're building and a **rationale record**
once you've shipped. Closing flips it from one to the other. The plan was a
ladder of slices and predictions; the record is the layer of meaning the code
can't hold — why this exists, what it must never break, what you tried that
failed. The code is the single source of truth for *how*; the closed spec is
the source of truth for *why*, and a map into the code.

Do not summarize the implementation. Anyone can read the code. If a paragraph
restates what a function does, cut it and point at the function instead.

## Workflow

1. **Confirm it shipped.** The feature is merged or working in-tree and its
   tests/screenshot gates are green. If slices remain unverified, it isn't
   done — finish or [review](../review/SKILL.md) first.

2. **Diff plan against reality.** Read the spec's README and slices, then read
   what actually landed. Note every place the build diverged from the plan:
   dropped slices, renamed seams, a mechanic that turned out different, an
   assumption that broke. The divergences are the most valuable thing to
…

How to install

The exact contents, by fingerprint
mdr add dzhng/skills/close-spec@sha256:1037876ce3e240ac

The line at the top of this page pins the label git:20260721.2ee48ec, 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.
