Use when a workflow step drafts or revises a spec artifact — a goal-and-requirements, an architecture, or a module SPEC — or when a workflow skill names it at such a step. The shared quality bar for specs — not a workflow, nothing to execute.

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

# Writing Specs

The workflow family's shared bar for every spec a workflow produces: **short, honest, on-rails**.
Process skills name this concept at the steps that draft or revise specs; *what* to draft and *when*
stays with the referencing skill. Graph mechanics — frontmatter, link kinds, the `spec_*` tools — are
the spec-graph skill's ground; this concept carries the quality bar the family holds on top of them,
and is where the family's rules for specs and the spec graph accrue.

## Short

- Small enough to read in one sitting. Target signal, not completeness.
- Explain intent, not inventory: what the thing is for, what it owns, where its boundary runs — never
  a file listing or a restatement of the code.

## Honest

- Only settled content appears. Never pad with `[TBD]` or placeholder sections — a section that
  hasn't been settled simply doesn't exist yet.
- Anything inferred rather than confirmed is marked unconfirmed, inline, where it stands.
- New and inferred specs are `status: draft` until the user has reviewed them — the flip out of
  `draft` follows the user's review, never the drafting agent's own judgment. A reviewed durable spec

How to install

The exact contents, by fingerprint
mdr add jetbrains/thinkrail/writing-specs@sha256:3d5ab7144d0da5b1

The line at the top of this page pins the label git:20260929.fdbbc1d, 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.
