agent-native-audit

agent-native-audit is a command for Claude Code from tajmahal226/compound-engineering-plugin. It costs 14 tokens per session (1,999 once invoked), scanned A, original, MIT.

A codebase review command that checks whether an application is designed to work well with an AI agent and produces a scored report.

In plain words
What is it for?
Use it to review agent support across actions, tools, application context, shared data, create/read/update/delete operations, user-interface updates, capability discovery, and prompt-based features.
Why use it?
It identifies gaps between what a user can do and what an agent can do, including missing data access, actions, or interface updates.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

agent-native-audit scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

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

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

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
