Openspec Verify Change

Verify that an implementation matches the change artifacts (specs, tasks, design).

Store selection: If the user names a store (a store is a standalone OpenSpec repo registered on this machine) or the work lives in one, run openspec store list --json to discover registered store ids, then pass --store <id> on the commands that read or write specs and changes (new change, status, instructions, list, show, validate, archive, doctor, context, schemas, view). Once selected, treat --store <id> as sticky for the rest of the workflow. Every unscoped example of those commands below is shorthand: before running it, append the flag. For example, run openspec status --change "<name>" --json --store "<id>", not the unscoped form shown below. Other commands do not take the flag. Hints printed by commands already carry the flag; keep it on follow-ups. Without a store, commands act on the nearest local openspec/ root.

Input: Optionally specify a change name. If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.

Steps

1. Select the change

   If a name is provided, use it. Otherwise:

   • Infer from conversation context if the user mentioned a change
   • Auto-select if only one active change exists
   • If ambiguous, run openspec list --json to get available changes and ask the user to select one

   When prompting, show changes that have implementation tasks (tasks artifact exists). Include the schema used for each change if available. Mark changes with incomplete tasks as "(In Progress)".

   Always announce: "Using change: " and how to override (e.g., /opsx:verify <other>).

2. Check status to understand the schema

   openspec status --change "<name>" --json
   

   Parse the JSON to understand:

   • schemaName: The workflow being used (e.g., "spec-driven")
   • planningHome, changeRoot, artifactPaths, and actionContext: path and scope context
   • Which artifacts exist for this change

3. Get planning context and load artifacts

   openspec instructions apply --change "<name>" --json
   

   This returns the change directory and contextFiles (artifact ID -> array of concrete file paths). Read all available artifacts from contextFiles.

4. Initialize verification report structure

   Create a report structure with three dimensions:

   • Completeness: Track tasks and spec coverage
   • Correctness: Track requirement implementation and scenario coverage
   • Coherence: Track design adherence and pattern consistency

   Each dimension can have CRITICAL, WARNING, or SUGGESTION issues.

5. Verify Completeness

   Task Completion:

   • If contextFiles.tasks exists, read every file path in it
   • Parse checkboxes: - [ ] (incomplete) vs - [x] (complete)
   • Count complete vs total tasks
   • If incomplete tasks exist:
     • Add CRITICAL issue for each incomplete task
     • Recommendation: "Complete task: " or "Mark as done if already implemented"

   Spec Coverage:

   • If delta specs exist in contextFiles.specs:
     • Extract all requirements (marked with "### Requirement:")
     • For each requirement:
       • Search codebase for keywords related to the requirement
       • Assess if implementation likely exists
     • If requirements appear unimplemented:
       • Add CRITICAL issue: "Requirement not found: "
       • Recommendation: "Implement requirement X: "

6. Verify Correctness

   Requirement Implementation Mapping:

   • For each requirement from delta specs:
     • Search codebase for implementation evidence
     • If found, note file paths and line ranges
     • Assess if implementation matches requirement intent
     • If divergence detected:
       • Add WARNING: "Implementation may diverge from spec: "
       • Recommendation: "Review : against requirement X"

   Scenario Coverage:

   • For each scenario in delta specs (marked with "#### Scenario:"):
     • Check if conditions are handled in code
     • Check if tests exist covering the scenario
     • If scenario appears uncovered:
       • Add WARNING: "Scenario not covered: "
       • Recommendation: "Add test or implementation for scenario: "

7. Verify Coherence

   Design Adherence:

   • If contextFiles.design exists:
     • Extract key decisions (look for sections like "Decision:", "Approach:", "Architecture:")
     • Verify implementation follows those decisions
     • If contradiction detected:
       • Add WARNING: "Design decision not followed: "
       • Recommendation: "Update implementation or revise design.md to match reality"
   • If no design.md: Skip design adherence check, note "No design.md to verify against"

   Code Pattern Consistency:

   • Review new code for consistency with project patterns
   • Check file naming, directory structure, coding style
   • If significant deviations found:
     • Add SUGGESTION: "Code pattern deviation: "
     • Recommendation: "Consider following project pattern: "

8. Generate Verification Report

   Summary Scorecard:

   ## Verification Report: <change-name>
   
   ### Summary
   | Dimension    | Status           |
   |--------------|------------------|
   | Completeness | X/Y tasks, N reqs|
   | Correctness  | M/N reqs covered |
   | Coherence    | Followed/Issues  |
   

   Issues by Priority:

   1. CRITICAL (Must fix before archive):

      • Incomplete tasks
      • Missing requirement implementations
      • Each with specific, actionable recommendation

   2. WARNING (Should fix):

      • Spec/design divergences
      • Missing scenario coverage
      • Each with specific recommendation

   3. SUGGESTION (Nice to fix):

      • Pattern inconsistencies
      • Minor improvements
      • Each with specific recommendation

   Final Assessment:

   • If CRITICAL issues: "X critical issue(s) found. Fix before archiving."
   • If only warnings: "No critical issues. Y warning(s) to consider. Ready for archive (with noted improvements)."
   • If all clear: "All checks passed. Ready for archive."

Verification Heuristics

• Completeness: Focus on objective checklist items (checkboxes, requirements list)
• Correctness: Use keyword search, file path analysis, reasonable inference - don't require perfect certainty
• Coherence: Look for glaring inconsistencies, don't nitpick style
• False Positives: When uncertain, prefer SUGGESTION over WARNING, WARNING over CRITICAL
• Actionability: Every issue must have a specific recommendation with file/line references where applicable

Graceful Degradation

• If only tasks.md exists: verify task completion only, skip spec/design checks
• If tasks + specs exist: verify completeness and correctness, skip design
• If full artifacts: verify all three dimensions
• Always note which checks were skipped and why

Output Format

Use clear markdown with:

• Table for summary scorecard
• Grouped lists for issues (CRITICAL/WARNING/SUGGESTION)
• Code references in format: file.ts:123
• Specific, actionable recommendations
• No vague suggestions like "consider reviewing"
