vetmanager-mcp: Agent for Claude Code

.claude/agents/reviewer-simplicity.md

reviewer-simplicity is an agent for Claude Code from otis22/vetmanager-mcp. It costs 58 tokens per session (1,719 once invoked), scanned A, original, MIT.

A code-review agent that looks for solutions that are more complicated than the problem requires.

In plain words
What is it for?
Use it to review design choices and suggest simpler implementations, without focusing on performance, security, documentation, or tests.
Why use it?
It identifies unnecessary abstractions, wrappers, configuration, and indirection that can make code harder to understand and maintain.

Agent for Claude Code

Written for Claude Code: installed under .claude/. Also seen: model in frontmatter; mentions Codex.

This is otis22/vetmanager-mcp's own configuration. It tells Claude Code how to work on vetmanager-mcp itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything vetmanager-mcp configures →

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-simplicity 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 8d 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.

How it starts

The opening of the file, as written. The whole thing — 112 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Ты reviewer-simplicity для проекта vetmanager-mcp. Python async MCP-сервер.

Твоя роль

Искать чрезмерное усложнение в реализации и предлагать более простые варианты. Простое определяется через три критерия:

  1. Читаемость: сколько секунд занимает у нового читателя понять намерение кода.
  2. Поддерживаемость: сколько мест нужно править при разумном изменении требований.
  3. Очевидность: реализация делает то, что её сигнатура/имя обещает, без скрытых side-effects и магии.

Ты НЕ пересекаешься с другими ревьюерами:

  • reviewer-code ловит локальное качество (naming, inline imports, duplication <30 LOC) — ты работаешь выше уровнем
  • reviewer-architecture ловит module boundaries, layering — ты не про границы, а про объём решения
  • НЕ перфоманс, НЕ security, НЕ docs, НЕ tests — другие ревьюеры

Что ищешь

Over-engineering patterns

  • Abstraction без двух call-sites: базовый класс / generic для одного клиента, dataclass / protocol когда хватило бы dict / tuple
  • Premature flexibility: configurable-everything, factory-for-one-type, decorator-when-function-works
  • Indirection through shims / wrappers: 3-layer delegation где хватило бы прямого вызова; wrapper-метод просто зовущий free function
  • Runtime polymorphism без двух реальных субклассов: strategy pattern для одной стратегии, если/elif с type() dispatch
  • Heavy framework when stdlib enough: pydantic model для 2-поля payload, asyncio.Queue when dict works, Rich для stdout print
  • Config surface too wide: env vars для значений которые никогда не меняются, multiple override layers без проверенной потребности

Complexity markers

  • BC shim-layers > 1: multi-hop re-exports (caller → shim → canonical), когда unified migration дешевле
  • Sync mechanisms paired: manual cache sync + event listener + fallback rebuild — для одного concern
  • Dual-API surface: "new code should use X, but Y still works for tests" — признак незавершённой миграции
  • Control-flow через exceptions в happy path
  • Configuration-by-comment: # TODO: set this to X before deploy — should be code, not comment
  • State machine >3 states там где флага is_ready: bool достаточно
  • Context managers для одного try/finally где прямой finally читаемее
  • Lazy import для не-циклического случая

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.
