Q: How do I install openspec-verify?

Run npx skills add https://github.com/full-stack-skills/openspec-skills --skill openspec-verify in your project. The skills CLI detects the agents you use and copies the skill into the right folder. For Claude Code you can also place the skill folder at ~/.claude/skills/openspec-verify/ (personal) or .claude/skills/openspec-verify/ (project).

Validate that implementation matches change artifacts using /opsx:verify, checking completeness, correctness, and coherence. Use when the user says "verify implementation", "check my work", "/opsx:verify", or wants quality validation before archiving.

OpenSpec Verify Skill

Use /opsx:verify to validate that the implementation matches the change artifacts. Checks three dimensions — completeness, correctness, and coherence — and reports issues categorized as CRITICAL, WARNING, or SUGGESTION.

When to Use

After implementing tasks with openspec-apply, before archiving.
The user says "verify", "check my work", "validate implementation".
Quality gate before archiving a change.

Prerequisites

Tasks implemented (via openspec-apply or manual coding).

Workflow

Run verification
- /opsx:verify — verify the current/inferred change.
- /opsx:verify <change-name> — verify a specific change.

Three verification dimensions

Dimension	What it validates
Completeness	All tasks done, all requirements implemented, scenarios covered
Correctness	Implementation matches spec intent, edge cases handled
Coherence	Design decisions reflected in code, patterns consistent

Review the report
- CRITICAL: Must fix before archiving.
- WARNING: Should address; does not block archive.
- SUGGESTION: Optional improvements.
Fix issues if needed
- Address critical issues, optionally fix warnings.
- Run /opsx:verify again to confirm.

Outputs

Verification report with categorized issues (CRITICAL / WARNING / SUGGESTION).
Summary: ready to archive or not.

Next Steps

If ready: use openspec-archive to archive the change.
If issues found: fix code or update artifacts, then re-verify.

Troubleshooting

Many false positives: Add project context in openspec/config.yaml to help the agent understand conventions. See openspec-config.
