architecture-review

architecture-review is a skill for Claude Code from viknesh20-20/claude-code-tool-kit. It costs 37 tokens per session (873 once invoked), scanned A, original, MIT.

A software architecture review guide that examines how a system’s parts depend on one another and where its structure may cause problems.

In plain words
What is it for?
Use it for a periodic system health check or before starting a major feature.
Why use it?
It helps find tangled dependencies, layers used incorrectly, scaling risks, and single points of failure before they become costly to fix.

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

architecture-review 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 8d 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.

Review Areas

1. Project Structure & Organization

  • Is the directory layout clear and consistent?
  • Does it follow established conventions for the stack? (e.g., src/, app/, lib/, pkg/)
  • Are related files co-located or scattered?
  • Is there a clear entry point?

2. Dependency Architecture

  • Map the dependency graph between major modules/packages
  • Identify circular dependencies — modules that import each other
  • Check for layer violations — e.g., presentation layer importing directly from data layer
  • Look for god modules — modules that everything depends on
  • Assess coupling: can modules be changed independently?

3. Separation of Concerns

  • Is business logic separated from framework/transport code?
  • Are side effects (I/O, network, database) isolated at boundaries?
  • Is configuration separated from code?
  • Are there clear interfaces between layers?

4. Scalability Considerations

  • Stateless vs stateful components — which components hold state?
  • Are there bottlenecks that would fail under load?
  • Database query patterns — are they efficient at scale?
  • Caching strategy — what is cached, where, and when invalidated?
  • Background job handling — how are long-running tasks managed?

5. Reliability & Resilience

  • Single points of failure: What happens if any component goes down?
  • Error boundaries: Where do errors propagate, and are they caught?
  • Retry logic: For external service calls, is there retry with backoff?
  • Graceful degradation: Does the system handle partial failures?
  • Health checks: Are there endpoints or mechanisms to monitor health?

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.
