Turn a problem into testable requirements with acceptance criteria, through a first-principles gate, a memory-first prior-art gate, and a PRD schema. Use when you say `spec this out`, `what should we build`, or `define the requirements`, and run it before plan. Do NOT use to sequence work into milestones (use plan), do NOT use to write the code (use build), and do NOT use to emit the REQ, DESIGN and TASK files directly (use spec-generator, which this invokes).
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
<!-- vendor-portability: contributor-scoped citation. The retrospective at
.project-toolkit/retrospective/2026-05-05-pr-1887-iteration-paradox.md is the evidence for
why the Step 0 gate exists and lives upstream in the rjmurillo/ai-agents
repo; it is cited, not resolved at runtime (ADR-083). -->
Define what to build: a problem turned into requirements each of which can be
judged pass or fail, gated twice before any of it is written.
Migrated from the spec command under ADR-064, which makes skills the single
user-invocable surface. The command file is gone, so its path is named here in
plain text rather than as a citation to something a reader could open.
## Triggers
`spec this out`, `what should we build`, `define the requirements`,
`turn this into acceptance criteria`
## Arguments
Spec: $ARGUMENTS
If `$ARGUMENTS` is empty, ask the user what problem to solve. Do not proceed
without a problem statement.
## Process
### Step 0: First Principles Gate (blocking, runs before Step 1)

How to install
mdr add rjmurillo/ai-agents/spec@sha256:ec5bd7382148d865The line at the top of this page pins the label v1.0.0, 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.
