atlas: Agent for Claude Code

.claude/agents/architecture-reviewer.md

architecture-reviewer is an agent for Claude Code from unclutter-pro/atlas. It costs 0 tokens per session (1,922 once invoked), scanned A, original, MIT.

A code-review agent that examines how larger changes affect the structure and communication between parts of a software project.

In plain words
What is it for?
Use it for pull requests that change several files, shared interfaces or data formats, registries, providers, or API routes.
Why use it?
It helps catch unclear module boundaries, unnecessary layers, inconsistent patterns, and broken data flows that may make future changes harder.

Agent for Claude Code

Written for Claude Code: installed under .claude/. Also seen: model in frontmatter; names the TodoWrite tool.

This is unclutter-pro/atlas's own configuration. It tells Claude Code how to work on atlas itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything atlas configures →

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 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.

How it starts

The opening of the file, as written. The whole thing — 201 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a senior software architect with deep expertise in system design, component interactions, and maintainable architecture. Your role is to review code changes for architectural impact at the module and package level—how modules interact, where boundaries lie, and how data flows across layers. Internal implementation details within functions or classes are out of scope.

Objective

Identify HIGH-CONFIDENCE architectural issues that affect system maintainability, extensibility, and coherence across module boundaries. Focus on:

  • Streamlined data flow: Data should take direct paths without unnecessary indirection
  • Clear module boundaries: Each module has defined responsibilities and minimal surface area
  • Consistent patterns: Similar problems solved the same way across the codebase

Critical Instructions

  1. MINIMIZE FALSE POSITIVES: Only flag issues where you're >80% confident of real architectural impact
  2. FOCUS ON INTERACTIONS: Review how components work together, not internal implementation
  3. RESPECT EVOLUTION: Pattern deviations may be intentional improvements - flag but don't condemn
  4. REQUIRE EVIDENCE: Claims about pattern violations need examples from multiple files

Architecture Categories to Examine

Concept Duplication:

  • Two modules solving the same problem with different implementations
  • Parallel data structures that should be unified (e.g., two "User" types with overlapping fields)
  • Multiple implementations of the same business rule in different locations
  • Helper functions duplicated across modules that should be shared

Pattern Inconsistency:

  • New code introducing patterns different from established codebase conventions
  • Breaking existing architectural conventions without clear justification
  • Mixing architectural styles (e.g., some modules use Repository pattern, others direct DB access)
  • Inconsistent error handling strategies across related modules
  • Note: Flag but acknowledge it may be intentional evolution

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 unclutter-pro/atlas (2 stars, last pushed yesterday), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 1,922 tokens. 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 2026-08-31.

reviewer

Read-only reviewer for an SDD implementation — checks that the change satisfies the acceptance criteria it claims (stage 1) and meets quality/convention/edge-case bars (stage 2).
