name: reality-verification description: This skill should be used when the user asks to "verify a fix", "reproduce failure", "diagnose issue", "check BEFORE/AFTER state", "VF task", "reality check", or needs guidance on verifying fixes by reproducing failures before and after implementation. version: 0.1.0 user-invocable: false

Reality Verification

For fix goals: reproduce the failure BEFORE work, verify resolution AFTER.

Goal Detection

Classify user goals to determine if diagnosis is needed. See references/goal-detection-patterns.md for detailed patterns.

Quick reference:

• Fix indicators: fix, repair, resolve, debug, patch, broken, failing, error, bug
• Add indicators: add, create, build, implement, new
• Conflict resolution: If both present, treat as Fix

Command Mapping

For E2E/deployment verification, use MCP tools (playwright for UI, fetch for APIs).

BEFORE/AFTER Documentation

BEFORE State (Diagnosis)

Document in .progress.md under ## Reality Check (BEFORE):

## Reality Check (BEFORE)

**Goal type**: Fix
**Reproduction command**: `pnpm test`
**Failure observed**: Yes
**Output**:

FAIL src/auth.test.ts Expected: 200 Received: 401

**Timestamp**: 2026-01-16T10:30:00Z

AFTER State (Verification)

Document in .progress.md under ## Reality Check (AFTER):

## Reality Check (AFTER)

**Command**: `pnpm test`
**Result**: PASS
**Output**:

PASS src/auth.test.ts All tests passed

**Comparison**: BEFORE failed with 401, AFTER passes
**Verified**: Issue resolved

VF Task Format

Add as task 4.3 (after PR creation) for fix-type specs:

- [ ] 4.3 VF: Verify original issue resolved
  - **Do**:
    1. Read BEFORE state from .progress.md
    2. Re-run reproduction command: `<command>`
    3. Compare output with BEFORE state
    4. Document AFTER state in .progress.md
  - **Verify**: `grep -q "Verified: Issue resolved" ./specs/<name>/.progress.md`
  - **Done when**: AFTER shows issue resolved, documented in .progress.md
  - **Commit**: `chore(<name>): verify fix resolves original issue`

Test Quality Checks

When verifying test-related fixes, check for mock-only test anti-patterns. See references/mock-quality-checks.md for detailed patterns.

Quick reference red flags:

• Mock declarations > 3x real assertions
• Missing import of actual module under test
• All assertions are mock interaction checks (toHaveBeenCalled)
• No integration tests
• Missing mock cleanup (afterEach)
