Builds a new command, flag or behaviour in thin test-first slices, after settling the open decisions with the owner. Use when asked to "add", "build", "implement", "support" or "create" something, such as a new command, subcommand or flag.

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

# Build a feature

## 1. Read the closest existing feature

Find the command most like the one you are building and read it with its test: `src/commands/task/add.ts` for a write that returns an entity, `src/commands/today.ts` for a list, `src/commands/label/delete.ts` for a destructive write behind `--yes`. For a new command or subcommand, `add-command` is the checklist of every file to touch. Read the rules in `AGENTS.md`. Done when you can name the file you will copy patterns from.

## 2. Settle decisions in one round

List what the request leaves open: command and flag names (consistent verbs and flags across entities; see `docs/decisions/001-lenient-cli-ergonomics.md`), positional argument or named flag, the human and `--json` output, error codes, `--dry-run` and `--yes`, behaviour under a read-only token. Ask the owner all of them at once, each with your recommendation. Don't ask what the code can answer. Done when every decision has an answer.

## 3. Write "done" as checkable behaviours

How to install

The exact contents, by fingerprint
mdr add doist/todoist-cli/build-feature@sha256:20cf263cd06c468e

The line at the top of this page pins the label git:20261105.582c0e7, 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.
