OpenSpec Reflect

Pre-gate self-check skill. Verifies acceptance criteria, detects scope drift, and ensures philosophy alignment before human review.

Workflow: Check → Assess → Report

Critical: Run before human gates. Catches drift BEFORE human reviews.

Commands

reflect

Run comprehensive pre-gate self-check.

Input: $ARGUMENTS = change-id

Workflow:

1. Load context:

   • Read openspec/changes/{change-id}/proposal.md for acceptance criteria
   • Read openspec/changes/{change-id}/tasks.md for progress
   • Read openspec/changes/{change-id}/test.md for test strategy (if exists)
   • Read openspec/changes/{change-id}/specs/*.md for requirements
   • Read openspec/project.md for Execution Philosophy

2. Pre-gate check (scale/maintenance mode only):

   • Check if test.md exists
   • If missing in scale/maintenance mode: flag ⚠️ MISSING_TEST_MD deviation
   • In garage mode: test.md optional (note if missing, don't block)

3. Check acceptance criteria:

   • Extract criteria from proposal.md (Success Criteria section)
   • For each criterion: verify met/unmet/partial
   • Record evidence for each status

4. Detect scope drift:

   • Extract "Affected files" from proposal.md
   • Run git status and git diff --stat to find actual changes
   • Calculate deviation percentage: (actual - proposed) / proposed * 100
   • Flag if >20% deviation

5. Check philosophy alignment:

   • Read mode from Execution Philosophy
   • Review implementation for anti-patterns of current mode
   • Flag any violations

6. Self-assessment:

   • Answer: "Am I solving the right problem?"
   • Evaluate: Is work aligned with proposal's Problem statement?

7. Generate gate-ready report (see format below)

Guardrails

Autonomous (no confirmation needed):

• Reading all context files
• Analyzing implementation
• Generating reports
• Flagging deviations

Ask-first (pause and confirm):

• None - reflect is read-only and advisory

Philosophy Check

Read openspec/project.md → Execution Philosophy → mode.

Mode	Flag Anti-patterns
garage	Over-engineering, premature abstraction, analysis paralysis
scale	Cowboy coding, skipping tests, undocumented decisions
maintenance	Refactoring for aesthetics, feature creep, risky upgrades

Format: ⚠️ PHILOSOPHY VIOLATION ({mode}) - {anti-pattern}: {evidence}

Gate-Ready Report Format

# Reflection Report: {change-id}

## Test Strategy Coverage
- test.md: {present/missing}
- Mode: {mode}
{if missing + scale/maintenance: ⚠️ MISSING_TEST_MD - required for {mode} mode}
{if missing + garage: ℹ️ test.md optional in garage mode}
{if present: - Coverage: {summary of test.md sections}}

## Criteria Status
| Criterion | Status | Evidence |
|-----------|--------|----------|
| {criterion 1} | {met/unmet/partial} | {evidence} |
| {criterion 2} | {met/unmet/partial} | {evidence} |

## Scope Analysis
- Proposed files: {n}
- Actual files: {m}
- Deviation: {percent}%
{if >20%: ⚠️ SCOPE DRIFT DETECTED - requires human review}

## Philosophy Alignment
- Mode: {mode}
- Anti-patterns detected: {list or "None"}
{if violations: ⚠️ PHILOSOPHY VIOLATION - {details}}

## Self-Assessment
**Question**: Am I solving the right problem?
**Answer**: {assessment based on proposal's Problem statement}

## Deviations Requiring Attention
{list with ⚠️ emoji for each, or "None"}

## Recommendation
{READY FOR GATE | NOT READY - {reasons}}

Deviation Types

• MISSING_TEST_MD - test.md missing in scale/maintenance mode
• SCOPE_DRIFT - Files changed exceed proposal by >20%
• CRITERIA_UNMET - Acceptance criterion not satisfied
• PHILOSOPHY_VIOLATION - Anti-pattern for current mode
• SPEC_DEVIATION - Implementation differs from specs

Format: ⚠️ DEVIATION: {type} - Expected: {X}, Actual: {Y}, Impact: {Z}, Rec: {action}

See reference.md for detailed examples and patterns.
