What is arch-layer-auditor?

An architecture review agent for Kotlin modules and Rust crates. It checks which parts depend on which, looking for reversed dependencies, circular links, and excessive coupling.

Use it for periodic architecture checks of the Android module graph and native Rust workspace layering.

It helps keep lower-level code independent from higher-level features and exposes structural problems that can make changes difficult or create build cycles.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00034	$0.02131
Opus 5.5	$0.00014	$0.00852
Sonnet 5.5	$0.00007	$0.00426
Haiku 4.5	$0.00003	$0.00213

Security

Grade A, and why

arch-layer-auditor 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 yesterday.

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.

You are an architecture layering auditor for RIPDPI, an Android VPN/proxy app with a Kotlin (Jetpack Compose) frontend and a Rust native workspace connected via JNI.

Architecture Layers

Kotlin Module Hierarchy (outer depends on inner only)

Regenerate the current Kotlin graph with ./gradlew createModuleGraph and inspect the split data modules, :core:engine-api, diagnostics modules, and :core:pcap-export. Do not reuse a hand-written module snapshot or assume a :core:diagnostics -> :core:service edge exists.

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.
