ln-24-architecture-auditor

ln-24-architecture-auditor is a skill for Claude Code from levnikolaevich/claude-code-skills. It costs 31 tokens per session (2,465 once invoked), scanned A, original, MIT.

A read-only review of the architecture a software system actually runs, including its structure, boundaries, dependencies, contracts, and ownership of configuration.

In plain words
What is it for?
Use it to assess an existing system's architecture and identify structural problems without changing code.
Why use it?
It reveals whether the system's parts fit current product needs and where responsibilities or dependencies are misplaced.

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

ln-24-architecture-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 5d 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.

How it starts

The opening of the file, as written. The whole thing — 111 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Architecture Auditor

Goal: Perform a read-only audit of the architecture the system actually executes. Evaluate whether structure, dependencies, contracts, and cross-component ownership fit current product needs without rewarding pattern names or speculative modernization. Judge where atomicity and resource ownership belong; leave local query, transaction, and data-resource correctness to a persistence-focused review.

Execution contract: The ordered checkboxes are the Definition of Done. Track every item internally as PENDING, PROVEN with concrete evidence, CLEARED with evidence that its condition is absent, or UNPROVEN with a gap; reading, delegation, or tool failure is not proof. Reconcile items after each section. Before returning, resolve all PENDING and count only PROVEN and CLEARED; apply the skill's verdict and approval rules to every gap. Preserve user intent, scope, and existing authorization. Continue authorized work; ask only for consequential unresolved choices or required external approval. Scale depth to material risk without silently skipping checks. Preserve dependency and safety ordering; otherwise choose the verification method appropriate to each obligation.

Tool Routing

Need Preferred tool Use it when Fallback
Physical and declared architecture Native file listing, manifests, build files, configuration, and architecture documents Establishing modules, packages, domains, layers, entrypoints, and deployment units Targeted repository map from known entrypoints
Symbols and dependency topology Language server, compiler metadata, or host-native code intelligence Tracing imports, calls, implementations, routes, events, and cycles Narrow search plus direct inspection of definitions and consumers
Runtime wiring Registration code, dependency injection, routing, startup configuration, and safe runtime diagnostics A component may exist but not be discoverable or connected Static trace with explicit uncertainty
Historical intent Git history, blame, and decision records A current exception or parallel mechanism may have a still-valid reason Current behavior and documented constraints remain authoritative
Architectural fitness Current official framework and platform documentation A finding depends on supported extension, lifecycle, configuration, or boundary behavior Primary-source web research; otherwise mark UNVERIFIED
Quantitative structure Existing dependency, cycle, complexity, or package-analysis commands The repository already defines reliable structural analysis Reproducible static inventory and call-path evidence

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.
