+
+# Agent-Native Architecture Audit
+
+Conduct a comprehensive review of the codebase against agent-native architecture principles, launching parallel sub-agents for each principle and producing a scored report.
+
+## Core Principles to Audit
+
+1. **Action Parity** - "Whatever the user can do, the agent can do"
+2. **Tools as Primitives** - "Tools provide capability, not behavior"
+3. **Context Injection** - "System prompt includes dynamic context about app state"
+4. **Shared Workspace** - "Agent and user work in the same data space"
+5. **CRUD Completeness** - "Every entity has full CRUD (Create, Read, Update, Delete)"
+6. **UI Integration** - "Agent actions immediately reflected in UI"
+7. **Capability Discovery** - "Users can discover what the agent can do"
+8. **Prompt-Native Features** - "Features are prompts defining outcomes, not code"
+
+## Workflow
+
+### Step 1: Load the Agent-Native Skill
+
+First, invoke the agent-native-architecture skill to understand all principles:
+
+```
+/compound-engineering:agent-native-architecture
+```
+
+Select option 7 (action parity) to load the full reference material.
+
+### Step 2: Launch Parallel Sub-Agents
+
+Launch 8 parallel sub-agents using the Task tool with `subagent_type: Explore`, one for each principle. Each agent should:
+
+1. Enumerate ALL instances in the codebase (user actions, tools, contexts, data stores, etc.)
+2. Check compliance against the principle
+3. Provide a SPECIFIC SCORE like "X out of Y (percentage%)"
+4. List specific gaps and recommendations
+
+<sub-agents>
+
+**Agent 1: Action Parity**
+```
+Audit for ACTION PARITY - "Whatever the user can do, the agent can do."
+
+Tasks:
+1. Enumerate ALL user actions in frontend (API calls, button clicks, form submissions)
+   - Search for API service files, fetch calls, form handlers
+   - Check routes and components for user interactions
+2. Check which have corresponding agent tools
+   - Search for agent tool definitions
+   - Map user actions to agent capabilities
+3. Score: "Agent can do X out of Y user actions"
+
+Format:
+## Action Parity Audit
+### User Actions Found
+| Action | Location | Agent Tool | Status |
+### Score: X/Y (percentage%)
+### Missing Agent Tools
+### Recommendations
+```
+
+**Agent 2: Tools as Primitives**
+```
+Audit for TOOLS AS PRIMITIVES - "Tools provide capability, not behavior."
+
+Tasks:
+1. Find and read ALL agent tool files
+2. Classify each as:
+   - PRIMITIVE (good): read, write, store, list - enables capability without business logic
+   - WORKFLOW (bad): encodes business logic, makes decisions, orchestrates steps
+3. Score: "X out of Y tools are proper primitives"
+
+Format:
+## Tools as Primitives Audit
+### Tool Analysis
+| Tool | File | Type | Reasoning |
+### Score: X/Y (percentage%)
+### Problematic Tools (workflows that should be primitives)
+### Recommendations
+```
+
+**Agent 3: Context Injection**
+```
+Audit for CONTEXT INJECTION - "System prompt includes dynamic context about app state"
+
+Tasks:
+1. Find context injection code (search for "context", "system prompt", "inject")
+2. Read agent prompts and system messages
+3. Enumerate what IS injected vs what SHOULD be:
+   - Available resources (files, drafts, documents)
+   - User preferences/settings
+   - Recent activity
+   - Available capabilities listed
+   - Session history
+   - Workspace state
+
+Format:
+## Context Injection Audit
+### Context Types Analysis
+| Context Type | Injected? | Location | Notes |
+### Score: X/Y (percentage%)
+### Missing Context
+### Recommendations
+```
+
+**Agent 4: Shared Workspace**
+```
+Audit for SHARED WORKSPACE - "Agent and user work in the same data space"
+
+Tasks:
+1. Identify all data stores/tables/models
+2. Check if agents read/write to SAME tables or separate ones
+3. Look for sandbox isolation anti-pattern (agent has separate data space)
+
+Format:
+## Shared Workspace Audit
+### Data Store Analysis
+| Data Store | User Access | Agent Access | Shared? |
+### Score: X/Y (percentage%)
+### Isolated Data (anti-pattern)
+### Recommendations
+```
+
+**Agent 5: CRUD Completeness**
+```
+Audit for CRUD COMPLETENESS - "Every entity has full CRUD"
+
+Tasks:
+1. Identify all entities/models in the codebase
+2. For each entity, check if agent tools exist for:
+   - Create
+   - Read
+   - Update
+   - Delete
+3. Score per entity and overall
+
+Format:
+## CRUD Completeness Audit
+### Entity CRUD Analysis
+| Entity | Create | Read | Update | Delete | Score |
+### Overall Score: X/Y entities with full CRUD (percentage%)
+### Incomplete Entities (list missing operations)
+### Recommendations
+```
+
+**Agent 6: UI Integration**
+```
+Audit for UI INTEGRATION - "Agent actions immediately reflected in UI"
+
+Tasks:
+1. Check how agent writes/changes propagate to frontend
+2. Look for:
+   - Streaming updates (SSE, WebSocket)
+   - Polling mechanisms
+   - Shared state/services
+   - Event buses
+   - File watching
+3. Identify "silent actions" anti-pattern (agent changes state but UI doesn't update)
+
+Format:
+## UI Integration Audit
+### Agent Action → UI Update Analysis
+| Agent Action | UI Mechanism | Immediate? | Notes |
+### Score: X/Y (percentage%)
+### Silent Actions (anti-pattern)
+### Recommendations
+```
+
+**Agent 7: Capability Discovery**
+```
+Audit for CAPABILITY DISCOVERY - "Users can discover what the agent can do"
+
+Tasks:
+1. Check for these 7 discovery mechanisms:
+   - Onboarding flow showing agent capabilities
+   - Help documentation
+   - Capability hints in UI
+   - Agent self-describes in responses
+   - Suggested prompts/actions
+   - Empty state guidance
+   - Slash commands (/help, /tools)
+2. Score against 7 mechanisms
+
+Format:
+## Capability Discovery Audit
+### Discovery Mechanism Analysis
+| Mechanism | Exists? | Location | Quality |
+### Score: X/7 (percentage%)
+### Missing Discovery
+### Recommendations
+```
+
+**Agent 8: Prompt-Native Features**
+```
+Audit for PROMPT-NATIVE FEATURES - "Features are prompts defining outcomes, not code"
+
+Tasks:
+1. Read all agent prompts
+2. Classify each feature/behavior as defined in:
+   - PROMPT (good): outcomes defined in natural language
+   - CODE (bad): business logic hardcoded
+3. Check if behavior changes require prompt edit vs code change
+
+Format:
+## Prompt-Native Features Audit
+### Feature Definition Analysis
+| Feature | Defined In | Type | Notes |
+### Score: X/Y (percentage%)
+### Code-Defined Features (anti-pattern)
+### Recommendations
+```
+
+</sub-agents>
+
+### Step 3: Compile Summary Report
+
+After all agents complete, compile a summary with:
+
+```markdown
+## Agent-Native Architecture Review: [Project Name]
+
