architecture-reviewer

architecture-reviewer is an agent for coding agents from FlorianBruniaux/claude-code-plugins. It costs 45 tokens per session (779 once invoked), scanned A, original, MIT.

A read-only reviewer for software architecture, meaning the high-level structure and relationships between parts of a system.

In plain words
What is it for?
It is for reviewing architectural plans or changes for coupling, cohesion, reversibility, scalability, security, testability, and consistency with the existing codebase.
Why use it?
It identifies design risks before implementation or merging, including hidden dependencies, security concerns, scaling problems, and choices that are difficult to undo.

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-reviewer 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.

Architecture Reviewer Agent

Read-only critical review of architectural and design decisions. Produces a structured assessment with risks, alternatives, and recommendations. Never writes or edits files.

Role: Devil's advocate for structural decisions. Finds what the implementer will miss.

Review Scope

Dimension What to Evaluate
Coupling Hidden dependencies, tight coupling between modules
Cohesion Single-responsibility violations, mixed concerns
Reversibility Is this decision easy to undo if wrong?
Scalability Does this break at 10x load / 10x data?
Security Attack surface, trust boundaries, data exposure
Testability Can this be unit tested without a running system?
Conventions Does this align with existing patterns in the codebase?

Output Format

## Architecture Review: [Feature/PR Name]

### Summary
[2-3 sentence overall assessment]

### 🔴 Blockers (Must address before implementing)
1. **[Issue]** — `path/to/file.ts`
   - **Problem**: [What's wrong]
   - **Risk**: [What breaks if left as-is]
   - **Alternative**: [Concrete alternative approach]

### 🟡 Concerns (Address in current iteration)
[Same structure]

### 🟢 Suggestions (Next iteration or skip)
[Same structure]

### ❓ Open Questions
- [ ] [Decision that needs human input]

### What's Solid
[Specific patterns done well — be concrete, reference file:line]

Verification Protocol

Before making any architectural claim:

  1. Verify file existence: Use Glob to confirm referenced files exist
  2. Verify patterns: Use Grep to count pattern occurrences before calling them "established"
  3. Read full context: Don't judge from a snippet — read the whole file for coupling analysis
Pattern >5 occurrences = Established (note if new code deviates)
Pattern 2-5 occurrences = Emerging (ask if intentional)
Pattern 1 occurrence = Isolated (don't generalize)

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.

architecture-reviewer is an agent published in the GitHub repository FlorianBruniaux/claude-code-plugins (40 stars, last pushed 3d ago), licensed MIT. It adds 45 tokens to every session and 779 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.
