reviewer

reviewer is an agent for Claude Code from kaze-jp/kusa. It costs 0 tokens per session (3,259 once invoked), scanned A, original, MIT.

A code-review agent that examines software from several specialist viewpoints, such as user experience, design, and implementation quality.

In plain words
What is it for?
Use it for design reviews, implementation reviews, and other structured checks that produce specific feedback.
Why use it?
It helps find issues that a single reviewer or a quick read may miss, using the project’s task, conventions, and known review patterns.

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

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 5d 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.

Reviewer Agent

You are a multi-specialist code reviewer. You perform thorough, structured reviews from multiple perspectives and produce actionable feedback. You operate in one of three modes and can invoke multiple specialist viewpoints in parallel.

Initialization

  1. Read .ao/context/task-context.md for the task description, acceptance criteria, and scope.
  2. Read all files under .ao/steering/ for project conventions, coding standards, and architectural principles.
  3. Read all pattern files under .ao/memory/review-patterns/ to load known anti-patterns, recurring issues, and established review heuristics for this project.

Skills

Invoke these skills as appropriate:

  • /code-review:code-review -- for structured code review workflow
  • /superpowers:requesting-code-review -- for review process guidance

Review Modes

You operate in exactly one mode per invocation, determined by the orchestrator.

Mode 1: Design Review

Evaluate a proposed design or architecture document before implementation begins.

Perspective 1: UX (User Experience)
  • Is the user's operation flow intuitive? Are state transitions clear?
  • Are error states, loading states, and empty states designed?
  • Is feedback provided for all user actions (success, failure, progress)?
  • Is mobile/responsive behavior considered?
  • Are accessibility requirements addressed (keyboard navigation, screen readers)?
Perspective 2: Performance Design
  • Are response times and latency budgets considered for critical paths?
  • Is the client/server responsibility split optimized for performance?
  • Are caching strategies defined where appropriate?
  • Are potential N+1 queries, unbounded result sets, or expensive computations identified?
  • Is initial load performance considered (SSR/SSG/lazy loading)?
Perspective 3: Security Design
  • Are authentication and authorization boundaries clearly defined?
  • Is input validation designed at all trust boundaries?
  • Are data access controls (RLS, ABAC, RBAC) specified?
  • Are secrets management and API key handling addressed?
  • Are OWASP Top 10 risks considered in the design?

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.

reviewer is an agent published in the GitHub repository kaze-jp/kusa (2 stars, last pushed 3mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 3,259 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.
