agent-architecture-audit

agent-architecture-audit is a skill for Claude Code, Codex from Bilal140202/the-lord-of-the-skills. It costs 70 tokens per session (2,297 once invoked), scanned A, a copy of agent-architecture-audit, MIT.

A diagnostic workflow for applications that use AI agents or language models. It examines the layers around the model, including tool calls, memory, retries, wrappers, and response display.

In plain words
What is it for?
Auditing an agent application before release, investigating degraded agent behavior, and finding code-level causes of problems in tool calling, memory, multi-step workflows, or response rendering.
Why use it?
It helps locate failures that are hidden by surrounding application code, such as stale memory, repeated repair attempts, unreliable tools, or corrupted output.

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-architecture-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 12d 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 Architecture Audit

A diagnostic workflow for agent systems that hide failures behind wrapper layers, stale memory, retry loops, or transport/rendering mutations.

When to Activate

MANDATORY for:

  • Releasing any agent or LLM-powered application to production
  • Shipping features with tool calling, memory, or multi-step workflows
  • Agent behavior degrades after adding wrapper layers
  • User reports "the agent is getting worse" or "tools are flaky"
  • Same model works in playground but breaks inside your wrapper
  • Debugging agent behavior for more than 15 minutes without finding root cause

Especially critical when:

  • You've added new prompt layers, tool definitions, or memory systems
  • Different agents in your system behave inconsistently
  • The model was fine yesterday but is hallucinating today
  • You suspect hidden repair/retry loops silently mutating responses

Do not use for:

  • General code debugging: use agent-introspection-debugging
  • Code review: use language-specific reviewer agents
  • Security scanning: use security-review or security-review/scan
  • Agent performance benchmarking: use agent-eval
  • Writing new features: use the appropriate workflow skill

The 12-Layer Stack

Every agent system has these layers. Any of them can corrupt the answer:

# Layer What Goes Wrong
1 System prompt Conflicting instructions, instruction bloat
2 Session history Stale context injection from previous turns
3 Long-term memory Pollution across sessions, old topics in new conversations
4 Distillation Compressed artifacts re-entering as pseudo-facts
5 Active recall Redundant re-summary layers wasting context
6 Tool selection Wrong tool routing, model skips required tools
7 Tool execution Hallucinated execution: claims to call but doesn't
8 Tool interpretation Misread or ignored tool output
9 Answer shaping Format corruption in final response
10 Platform rendering Transport-layer mutation (UI, API, CLI mutates valid answers)
11 Hidden repair loops Silent fallback/retry agents running second LLM pass
12 Persistence Expired state or cached artifacts reused as live evidence

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.
