Project context preflight before workflow actions: before this skill takes a workflow action, follow the project-constitution skill. Read root CONSTITUTION.md when present, enforce relevant project rules, stop on material conflicts, and follow the strict missing-constitution bootstrap/diagnostic policy. For architecture-sensitive work, also read ARCHITECTURE.md, adr/README.md, and relevant in-force adr/*.md. Read .secrets.local.env only when the current workflow actually needs a listed external system, and never reveal secret values.

OpenSpec Overlay Check

Validate the project-local intent-driven overlay without patching OpenSpec. Prefer scripts/check-overlay when present; otherwise follow the manual steps below.

Steps

1. Show the OpenSpec version:

   openspec --version
   

2. List schemas and confirm intent-driven is project-local:

   openspec schemas --json
   

3. Validate the schema:

   openspec schema validate intent-driven
   

4. List active changes with a command valid in OpenSpec 1.3.x:

   openspec list --json
   

5. Create a temporary smoke change using the intent-driven schema:

   openspec new change zz-smoke-intent-overlay-<unique> --schema intent-driven
   openspec status --change zz-smoke-intent-overlay-<unique> --json
   # after writing minimal proposal/specs/grill/design/design-review/adr/test-plan/tasks artifacts:
   openspec instructions apply --change zz-smoke-intent-overlay-<unique> --json
   

6. Report the compatibility layer for any failure:

   • OpenSpec CLI command changed
   • local intent-driven schema invalid
   • Codex prompt/skill adapter mismatch
   • generated skill mismatch
   • existing project artifact issue

7. Cleanup policy:

   • The script may automatically delete only a zz-smoke-intent-overlay-* change that it created in the same run.
   • Use --keep-smoke when the user wants to inspect the smoke change.
   • Never delete user-created changes or project artifacts silently.

Guardrails

• Do not run bare openspec status --json; OpenSpec 1.3.x requires --change.
• Do not modify OpenSpec package files.
• Do not overwrite openspec/changes/**, openspec/specs/**, or adr/**.
