/hk-arch-audit — Agent-Native Architecture Review

Conducts a comprehensive review of the codebase against agent-native architecture principles, launching parallel sub-agents for each principle and producing a scored report.

Context

<audit_context> $ARGUMENTS </audit_context>

Core Principles

#	Principle	One-liner
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 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 reference material

Read references/agent-prompts.md in this skill's directory to get the detailed prompt for each sub-agent. That file contains the exact instructions, search strategies, and output format for all 8 principle audits.

Step 2: Check for single-principle audit

If $ARGUMENTS specifies a single principle, only run that one sub-agent. Valid argument forms:

Argument	Principle
action parity or 1	Action Parity
tools or primitives or 2	Tools as Primitives
context or injection or 3	Context Injection
shared or workspace or 4	Shared Workspace
crud or 5	CRUD Completeness
ui or integration or 6	UI Integration
discovery or 7	Capability Discovery
prompt or features or 8	Prompt-Native Features

For single-principle audits, run one Explore sub-agent and present its findings directly — no summary table needed.

Step 3: Launch parallel sub-agents

Launch 8 parallel sub-agents using the Task tool with subagent_type: Explore, one per principle. Each agent should:

1. Enumerate all relevant instances in the codebase (user actions, tools, contexts, data stores, etc.)
2. Check compliance against the principle
3. Provide a specific score in X out of Y (percentage%) format
4. List specific gaps and recommendations

Read references/agent-prompts.md for the exact prompt to give each agent. Pass the full agent prompt from that file — don't summarize it.

Step 4: Compile summary report

After all agents complete, compile the summary using this template:

### Overall Score Summary

| Core Principle | Score | Percentage | Status |
|----------------|-------|------------|--------|
| Action Parity | X/Y | Z% | STATUS |
| Tools as Primitives | X/Y | Z% | STATUS |
| Context Injection | X/Y | Z% | STATUS |
| Shared Workspace | X/Y | Z% | STATUS |
| CRUD Completeness | X/Y | Z% | STATUS |
| UI Integration | X/Y | Z% | STATUS |
| Capability Discovery | X/Y | Z% | STATUS |
| Prompt-Native Features | X/Y | Z% | STATUS |

**Overall Agent-Native Score: X%**

### What's Working Well

[List top 5 strengths]

Success criteria

• All 8 sub-agents complete their audits (or the single requested one)
• Each principle has a specific numeric score (X/Y format)
• Summary table shows all scores and status indicators
• Top 10 recommendations are prioritized by impact
• Report identifies both strengths and gaps
