rara-docs-spec SKILL.md skillA

rara-docs-spec from linkerdog/rara is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned

mdr add linkerdog/rara/rara-docs-spec@git:20260512.3a03083

Pins git:20260512.3a03083 in mdr.lock. Pin the fingerprint instead.

Use when creating, revising, or reviewing RARA canonical feature specs under docs/features/. Applies to stable runtime, TUI, protocol, memory, provider, skill, plugin, and tool contracts, including scope boundaries and validation matrices.

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

# RARA Feature Spec Writing

Use this skill when writing or reviewing `docs/features/*.md` files in this
repository.

## Goal

Keep feature specs as the stable source of truth for:

- product and engineering scope
- runtime, TUI, protocol, or tool contracts
- architecture boundaries
- validation expectations
- known operational risks

Feature specs are not date-stamped rollout notes and should not read like a
PR-by-PR changelog.

## Surface Rules

- Canonical specs live under `docs/features/`.
- Filenames are topic-oriented kebab-case.
- Do not use date prefixes in `docs/features/`.
- Chronological implementation notes belong in `docs/journal/`.
- Open rollout tails belong in `docs/todo.md`.

## Structure

Prefer these sections for active specs:

- `Problem`
- `Scope`
- `Non-Goals`
- `Architecture`
- `Contracts`
- `Validation Matrix`
- `Operational Notes`
- `Open Risks`
- `Source Journals`

If a section is intentionally short, keep it short, but do not silently drop
scope, non-goals, contracts, or validation.

## Writing Rules

### Capture Stable Contracts

A spec should answer what behavior is intended, what boundary is canonical, and
what downstream consumers can rely on.

How to install

The exact contents, by fingerprint

mdr add linkerdog/rara/rara-docs-spec@sha256:461d7fb9b67dd999

The line at the top of this page pins the label git:20260512.3a03083, 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.
