name openspec-check
description Use BEFORE any implementation to check if specs exist for the capability. Run this first when starting any feature work. Reports: spec exists, no spec, or active change in progress.

OpenSpec Check

Verify spec status before implementation.

Announce: "I'm using openspec-check to verify spec status before proceeding."

Iron Law

NO IMPLEMENTATION WITHOUT CHECKING SPECS FIRST

Process

Step 1: List Current Specs

openspec list --specs

Identify which capability this work relates to:

  • algorithm - Game mechanics, scoring, ranking
  • database - Schema, RLS, data model
  • frontend - UI components, views, stores
  • game-core - Core gameplay loop
  • edge-functions - LLM, embeddings
  • operations - CI/CD, deployment

Step 2: Check Active Changes

openspec list

Look for:

  • Is there already a change in progress for this capability?
  • Would this work conflict with an active change?

Step 3: Read Relevant Spec

If spec exists:

openspec show [capability] --type spec

Check:

  • Does this work align with existing requirements?
  • Would this work modify existing behavior?
  • Are there scenarios that would be affected?

Step 4: Report Status

Report ONE of these outcomes:

A) Spec exists, work aligns:

Spec `[capability]` exists. This work aligns with requirement: [name].
Proceeding with implementation following existing spec.

→ Load test-tdd skill and implement

B) Spec exists, work would modify:

Spec `[capability]` exists but this work would modify requirement: [name].
This needs an OpenSpec proposal before implementation.

→ Load openspec-propose skill

C) No spec exists, new capability:

No spec exists for this capability.
This is a new feature that needs an OpenSpec proposal.

→ Load openspec-propose skill

D) Active change in progress:

Active change `[change-id]` is in progress for this capability.
Status: [X/Y tasks complete]
Options:
1. Continue that change
2. Wait for it to complete
3. Create separate change (if unrelated)

→ ASK user how to proceed

E) Trivial fix, no spec needed:

This is a bug fix / typo / formatting change that restores intended behavior.
No spec change needed.

→ Load test-tdd skill and fix

REQUIRED SUB-SKILL

Based on outcome:

  • New feature or behavior change → Load openspec-propose
  • Aligned with spec or trivial fix → Load test-tdd

Red Flags - STOP

If you catch yourself:

  • Starting implementation without running this check
  • Assuming "this is too small to need a spec"
  • Ignoring active changes that might conflict

STOP. Run openspec list --specs and openspec list first.
