architecture-review

architecture-review is a skill for Claude Code, Codex from ntaffzii/Skill-Agents. It costs 52 tokens per session (350 once invoked), scanned A, original, MIT.

A review process for understanding how a codebase is organised and where its structure makes future changes difficult.

In plain words
What is it for?
Use it to map modules and data flow, identify architectural pressure, name domain concepts, propose small design changes, and define tests that check the result.
Why use it?
It reveals tangled module boundaries, hidden dependencies, repeated logic, unclear ownership, and weak points for testing before a large refactor.

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 10d 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.

What it actually says

Architecture Review

Use this skill to reason about structure before proposing broad changes.

Workflow

  1. Map the system

    • Identify the relevant modules, entry points, data flow, and ownership boundaries.
    • Read local docs, domain glossary, ADRs, and tests if present.
  2. Locate design pressure

    • Look for repeated conditionals, hidden coupling, unclear ownership, duplicated concepts, awkward test seams, and high-change files.
    • Distinguish annoying code from code that blocks future work.
  3. Name the domain concepts

    • Use existing project language when available.
    • Flag mismatches where code names do not match business or product concepts.
  4. Propose changes

    • Prefer small boundary improvements over sweeping rewrites.
    • Give options when tradeoffs are meaningful.
    • Identify the first reversible step.
  5. Validate

    • Explain what tests or probes would prove the architecture change preserved behavior.
    • Avoid recommending refactors without a verification path.

Output Format

Current Shape
What the code is doing now.

Pressure Points
Specific issues with file references.

Recommended Move
The smallest valuable design improvement.

Validation
How to prove the change is safe.

Rules

  • Do not propose a rewrite unless incremental steps are impossible.
  • Do not introduce abstractions just because two blocks look similar.
  • Prefer deeper modules with simple interfaces over shallow layers that move complexity around.

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.
