Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00031 | $0.02465 |
| Opus 5 | $0.00015 | $0.01233 |
| Sonnet 5 | $0.00006 | $0.00493 |
| Haiku 4.5 | $0.00003 | $0.00247 |
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 |
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.

ln-24-architecture-auditor is a skill published in the GitHub repository levnikolaevich/claude-code-skills (559 stars, last pushed 5d ago), licensed MIT. It adds 31 tokens to every session and 2,465 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.

dev-rc
The last gate before merge — QA, security audit, review and changelog, with objective pass conditions.
triage-report
Drain the .review/ report queue. Resolves un-triaged scan/audit reports (producer-agnostic — check-docs-consistency and any other scanner), dispatches the triage-report subagent (Sonnet) one report at a time for per-finding dispositions (promote / patch / dup / needs-investigation / dismiss), then the gateway absorbs…
solid-principles
SOLID principles checklist with Java examples. Use when a class has too many responsibilities, an abstraction leaks, or a dependency points the wrong way, and when the user asks about Single Responsibility, Open/Closed, Liskov, Interface Segregation or Dependency Inversion. For naming, duplication and method length…
architecture-review
Analyze Java project architecture at macro level - package structure, module boundaries, dependency direction, and layering. Use when user asks "review architecture", "check structure", "package organization", or when evaluating if a codebase follows clean architecture principles.
java-code-review
Systematic code review for Java with null safety, exception handling, concurrency, and performance checks. Use when user says "review code", "check this PR", "code review", or before merging changes.
review-loop
Run the adversarial verification loop — implement, then hand the change to a fresh checker that did not write it, fix what it finds, and re-dispatch until APPROVE. Use before claiming any behavioural change is done, and on requests like "review loop", "adversarial review", "independent review", "get this verified"…
