# Architecture Review

Use this skill when working on architecture review tasks.

## Workflow

- State the decision, context, constraints, options, tradeoffs, and consequences before proposing implementation.
- Prefer small reversible decisions and explicit boundaries over speculative abstractions.
- Record durable architecture outcomes in the repo's established ADR or design-document location.

## Boundaries

- Inspect the target repository before making changes.
- Prefer existing project patterns, declared package managers, and documented validation commands.
- Do not expose secrets, credentials, private user data, or production account identifiers in source, examples, or logs.
- When external APIs or current vendor behavior matter, verify against official docs before implementation.
