+# /implement Command
+
+Implement iOS features from eval specs. Spawns verifier agent for checking - never tests own work.
+
+## Usage
+
+```
+/implement <eval-name>
+```
+
+## Flow
+
+```
+Read eval spec -> Check SwiftUI guide -> Implement -> Spawn verifier -> Fix if needed -> Done
+```
+
+## Process
+
+### 1. Load Eval Spec
+
+Read `.claude/evals/<name>.yaml` and extract `building_spec`:
+- description
+- requirements
+- constraints
+- files
+
+If no eval exists:
+```
+No eval spec found for "<name>".
+Create one first with: /eval <name>
+```
+
+### 2. Check SwiftUI Guide
+
+Read `.claude/axiom-skills-guide.md` for:
+- Project-specific iOS patterns
+- Architecture preferences
+- SwiftUI conventions
+
+If missing, use standard SwiftUI best practices.
+
+### 3. Implement
+
+Build the feature following the spec. iOS/SwiftUI guidelines:
+- `@State`, `@Binding`, `@ObservedObject` appropriately
+- `async/await` over completion handlers
+- `@MainActor` for UI updates
+- Small, composable Views
+- Proper error handling
+
+### 4. Spawn Verifier (MANDATORY)
+
+**NEVER verify own work.** Always spawn eval-verifier agent:
+
+```python
+verifier_result = spawn_agent("eval-verifier", {
+    "spec": f".claude/evals/{name}.yaml"
+})
+```
+
+The verifier:
+- Runs all checks from `verification_spec`
+- Collects evidence
+- Reports pass/fail
+
+### 5. Handle Results
+
+**Pass:** Report success and files changed.
+
+**Fail:** Read failure feedback, fix specific issues, re-spawn verifier.
+
+Max 5 iterations.
+
+## Orchestration Logic
+
+```python
+max_iterations = 5
+iteration = 0
+
+# Read spec
+spec = read_yaml(f".claude/evals/{name}.yaml")
+guide = read_file(".claude/axiom-skills-guide.md")  # optional
+
+# Implement
+implement(spec.building_spec, guide)
+
+while iteration < max_iterations:
+    # ALWAYS spawn verifier - never test own work
+    verifier_result = spawn_agent("eval-verifier", {
+        "spec": f".claude/evals/{name}.yaml"
+    })
+
+    if verifier_result.all_passed:
+        return success(verifier_result)
+
+    # Fix failures
+    fix_issues(verifier_result.failures)
+    iteration += 1
+
+return failure("Max iterations reached")
+```
+
+## Output
+
+```
+/implement auth

+
+[Loading eval spec: .claude/evals/auth.yaml]
+
+Building Spec:
+  - Login view with email/password
+  - Async authentication service
+  - Error handling with alerts
+
+[Checking .claude/axiom-skills-guide.md...]
+
+[Implementing...]
+
+Files Created:
+  + Sources/Features/Auth/LoginView.swift
+  + Sources/Features/Auth/AuthViewModel.swift
+  + Sources/Services/AuthService.swift
+
+Files Modified:
+  ~ Sources/App/ContentView.swift
+
+[Spawning eval-verifier...]
+
+Verification:
+  ✅ file-exists: LoginView.swift
+  ✅ file-contains: @MainActor
+  ✅ ui-login: Form renders correctly
+     📸 Evidence: 2 screenshots
+
+---
+Implementation complete: 3/3 checks passed
+```
+
+## Critical Rules
+
+1. **NEVER test own work** - always spawn eval-verifier
+2. **NEVER skip verification** - even if "confident"
+3. **NEVER claim pass without verifier confirmation**
+4. **Read the spec** - don't assume requirements
+5. **Minimal fixes** - on retry, fix only what failed
