Strict Enforcement Verification Methodology
When to use this skill
Use this skill when you need to:
- Run the
claudikins-kernel:verify command
- Validate implementation before shipping
- Decide pass/fail verdicts
- Check code integrity after changes
- Enforce cross-command gates
Core Philosophy
"Evidence before assertions. Always." - Verification philosophy
Never claim code works without seeing it work. Tests passing is not enough. Claude must SEE the output.
The Three Laws
- See it working - Screenshots, curl responses, CLI output. Actual evidence.
- Human checkpoint - No auto-shipping. Human reviews evidence and decides.
- Exit code 2 gates - Verification failures block claudikins-kernel:ship. No exceptions.
Verification Phases
Phase 1: Automated Quality Checks
Run the automated checks first. Fast feedback.
| Check | Command Pattern | What It Catches |
|---|
| Tests | npm test / pytest / cargo test | Logic errors, regressions |
| Lint | npm run lint / ruff / clippy | Style issues, common bugs |
| Types | tsc / mypy / cargo check | Type mismatches, interface drift |
| Build | npm run build / cargo build | Compilation errors, bundling issues |
Flaky Test Detection (C-12):
Test fails?
├── Re-run failed tests
├── Pass 2nd time?
│ └── Yes → STOP: [Accept flakiness] [Fix tests] [Abort]
└── Fail 2nd time?
├── Run isolated
└── Still fail? → STOP: [Fix] [Skip] [Abort]
Phase 2: Output Verification (catastrophiser)
This is the feedback loop that makes Claude's code actually work.
| Project Type | Verification Method | Evidence |
|---|
| Web app | Start server, screenshot, test flows | Screenshots, console logs |
| API | Curl endpoints, check responses | Status codes, response bodies |
| CLI | Run commands, capture output | stdout, stderr, exit codes |
| Library | Run examples, check results | Output values, test coverage |
| Service | Check logs, verify health endpoint | Log patterns, health responses |
Fallback Hierarchy (A-3):
If primary method unavailable, fall back:
- Start server + screenshot (preferred for web)
- Curl endpoints (preferred for API)
- Run CLI commands (preferred for CLI)
- Run tests only (fallback)
- Code review only (last resort)
Timeout: 30 seconds per verification method (CMD-30).
Phase 3: Code Simplification (Optional)
After verification passes, optionally run cynic for polish.
Prerequisites:
- Phase 2 (catastrophiser) must PASS
- Human approves: "Run cynic for polish pass?"
cynic Rules:
- Preserve exact behaviour (tests MUST still pass)
- Remove unnecessary abstraction
- Improve naming clarity
- Delete dead code
- Flatten nested conditionals
If tests fail after simplification:
- Log failure reasons
- Show human
- Proceed anyway (A-5) with caveat
See cynic-rollback.md for recovery patterns.
Phase 4: Klaus Escalation
If stuck during verification:
Is mcp__claudikins-klaus available? (E-16)
├── No →
│ Offer: [Manual review] [Ask Claude differently] (E-17)
│ Fallback: [Accept with uncertainty] [Max retries, abort] (E-18)
└── Yes →
Spawn klaus via SubagentStop hook
Phase 5: Human Checkpoint
The final gate. Present comprehensive evidence.
Verification Report
-------------------
Tests: ✓ 47/47 passed
Lint: ✓ 0 issues
Types: ✓ 0 errors
Build: ✓ success
Evidence:
- Screenshot: .claude/evidence/login-flow.png
- API test: POST /api/auth → 200 OK
- CLI test: mycli --help → exit 0
[Ready to Ship] [Needs Work] [Accept with Caveats]
Human decides. If approved, set unlock_ship = true.
Rationalizations to Resist
Agents under pressure find excuses. These are all violations:
| Excuse | Reality |
|---|
| "Tests pass, that's good enough" | Tests aren't enough. SEE it working. Screenshots, curl, output. |
| "I'll verify after shipping" | Verify BEFORE ship. That's the whole point. |
| "The type checker caught everything" | Types don't catch runtime issues. Get evidence. |
| "Screenshot failed but it probably works" | "Probably" isn't evidence. Fix the screenshot or use fallback. |
| "Human checkpoint is just a formality" | Human checkpoint is the gate. No auto-shipping. |
| "Code review is enough for this change" | Code review is last resort fallback. Try harder. |
| "Tests are flaky, I'll ignore the failure" | Flaky tests hide real failures. Fix or explicitly accept with caveat. |
| "Exit code 2 is too strict" | Exit code 2 exists to block bad ships. Pass properly. |
All of these mean: Get evidence. Human decides. No shortcuts.
Red Flags — STOP and Reassess
If you're thinking any of these, you're about to violate the methodology:
- "It should work because..."
- "The tests pass so..."
- "I'm confident that..."
- "It worked before..."
- "The types check so..."
- "I'll just skip verification this once"
- "Human will approve anyway"
- "Evidence isn't necessary for this change"
All of these mean: STOP. Get evidence. Present to human. Let them decide.
Exit Code 2 Pattern (CRITICAL)
The verify-gate.sh hook enforces the gate:
ALL_PASSED=$(jq -r '.all_checks_passed' "$STATE")
HUMAN_APPROVED=$(jq -r '.human_checkpoint.decision' "$STATE")
if [ "$ALL_PASSED" != "true" ]; then
exit 2
fi
if [ "$HUMAN_APPROVED" != "ready_to_ship" ]; then
exit 2
fi
File Manifest (C-6):
At verification completion, generate SHA256 hashes of all source files:
find . \( -name '*.ts' -o -name '*.py' -o -name '*.rs' \) \
| xargs sha256sum > .claude/verify-manifest.txt
This lets claudikins-kernel:ship detect if code was modified after verification.
Cross-Command Gate (C-14)
claudikins-kernel:verify requires claudikins-kernel:execute to have completed:
if [ ! -f "$EXECUTE_STATE" ]; then
echo "ERROR: claudikins-kernel:execute has not been run"
exit 2
fi
This enforces the claudikins-kernel:outline → claudikins-kernel:execute → claudikins-kernel:verify → claudikins-kernel:ship flow.
Agent Integration
| Agent | Role | When |
|---|
| catastrophiser | See code working | Phase 2: Output verification |
| cynic | Polish pass | Phase 3: Simplification (optional) |
Both agents run with context: fork and background: true.
See agent-integration.md for coordination patterns.
State Tracking
verify-state.json
{
"session_id": "verify-2026-01-16-1100",
"execute_session_id": "execute-2026-01-16-1030",
"branch": "execute/task-1-auth-middleware",
"phases": {

"lint": { "status": "PASS", "issues": 0 },
"type_check": { "status": "PASS", "errors": 0 },
"output_verification": { "status": "PASS"
Anti-Patterns
Don't do these:
- Trusting test results without seeing code run
- Skipping output verification because "tests pass"
- Auto-approving verification without human checkpoint
- Modifying code after verification passes
- Ignoring flaky test warnings
- Proceeding when lint/type checks fail
