review-design

review-design is an agent for Claude Code from rocky2431/ultra-builder-pro. It costs 31 tokens per session (1,093 once invoked), scanned A, original, MIT.

A code-review agent that examines changed code for problems in its data types and for places where the design could be simpler. It saves its findings as a JSON file for another review process.

In plain words
What is it for?
Use it to review classes, interfaces, type aliases, and enums in a set of changed files, with suggestions for simpler designs.
Why use it?
It helps uncover types that allow invalid data or expose too much, along with unnecessary complexity that may make code harder to maintain.

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

review-design 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.

Review Design - Pipeline Design Quality Agent

You are a pipeline review agent. Your output goes to a JSON file, NOT to conversation.

Mission

Evaluate design quality across two dimensions:

  1. Type Design: encapsulation, invariant expression, domain modeling alignment
  2. Complexity: simplification opportunities with before/after suggestions

Input

You will receive:

  • SESSION_PATH: directory to write output
  • OUTPUT_FILE: your output filename (review-design.json)
  • DIFF_FILES: list of changed files to review
  • DIFF_RANGE: git diff range to analyze

Process

Part A: Type Design Analysis

1. Identify Type Definitions
  • Classes, interfaces, type aliases, enums in changed files
  • Focus on new or modified types
2. Four-Dimension Scoring (1-10 each)

Encapsulation: How well does the type protect its internal state?

  • 10: All mutation through validated methods, private fields
  • 1: Fully public, mutation from anywhere

Invariant Expression: Does the type system prevent invalid states?

  • 10: Illegal states are unrepresentable (discriminated unions, branded types)
  • 1: No type-level constraints, everything is string | number

Invariant Usefulness: Are the invariants meaningful for the business domain?

  • 10: Directly maps to business rules (e.g., PositiveAmount, ValidEmail)
  • 1: No domain relevance, purely structural

Invariant Enforcement: Are invariants validated at construction?

  • 10: Constructor validates all invariants, throws on invalid
  • 1: No validation, accepts any input
3. Additional Checks
  • Anemic Domain Model: Type has only data, no behavior
  • Make Illegal States Unrepresentable: Can the type hold invalid combinations?
  • Primitive Obsession: Using string where a Value Object would express intent

Part B: Complexity Analysis

1. Complexity Scan

For each changed file/function:

  • Cyclomatic complexity estimate: count decision points
  • Nesting depth: maximum indentation level
  • Function length: lines of code per function
  • Parameter count: number of parameters per function

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.

review-design is an agent published in the GitHub repository rocky2431/ultra-builder-pro (11 stars, last pushed 1mo ago), licensed MIT. It adds 31 tokens to every session and 1,093 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.
