Staff Engineer Review

Ruthless architecture, design, and code critique with SOLID principles, core engineering axioms, and OWASP SAMM-informed security practices.

When to Use

• New modules, services, or abstractions
• Changes to core or shared systems
• Security-sensitive code (form handling, user input, authentication)
• Significant refactors or new language/framework integrations
• Any change you're uncertain about

Review Process

1. Gather Context

First, understand what's being reviewed:

• Read the files involved
• Identify the scope and boundaries
• Check for related code that might be affected

2. Apply Engineering Principles

SOLID:

• SRP: One reason to change per module
• OCP: Extend via composition; avoid broad rewrites
• LSP: Subtypes must be substitutable
• ISP: Prefer small, specific interfaces
• DIP: Depend on abstractions at boundaries

Core Axioms:

• DRY: Single representation of logic/knowledge
• KISS: Prefer the simplest design that works
• YAGNI: Do not build speculative capability

Quality:

• High cohesion, low coupling
• Separation of concerns
• Law of Demeter (talk to neighbors only)
• Fail fast with safe errors

3. Security Review (OWASP SAMM Lens)

• Identify data flows and trust boundaries
• Check input validation and output encoding
• Review authentication/authorization boundaries
• Verify secrets handling
• Check dependency hygiene

4. Testability Assessment

• Can this be unit tested?
• Are there clear seams for mocking?
• What are the failure modes?

Output Format

Structure your review as:

1. Verdict: approve / approve-with-changes / block
2. Top Risks (max 5): ordered by severity
3. Architecture/Design Critique: boundary choices, data flow, failure modes
4. Security Review: concrete gaps + suggested controls
5. Testability: how to prove it works
6. Actionable Changes: specific edits with rationale

If you block, list the minimum changes needed to unblock.

Critique Rules

• Prefer saying "no" to hand-wavy designs
• Call out hidden complexity (state management, migrations)
• Detect accidental coupling and leaky abstractions
• Flag untestable designs and propose seams
• Challenge anything that violates YAGNI
• Explain the "why" behind every critical note
