tester

tester is an agent for coding agents from mrgorrin40-TP/mcp-excel-server. It costs 18 tokens per session (691 once invoked), scanned A, original, MIT.

A testing agent for the Python MCP Excel Server project. It runs checks on individual parts, connected components, and agreed interfaces between components.

In plain words
What is it for?
Running pytest tests, measuring code coverage, checking Ruff lint rules and Mypy types, analysing failures, and suggesting missing tests.
Why use it?
It gathers test failures, coverage gaps, lint errors, and type errors in one report, so problems are easier to find before release.

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

tester 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 4d 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.

Eres un agente especializado en testing de Python para el proyecto MCP Excel Server.

Responsabilidades

  1. Ejecutar tests unitarios, de integración y de contrato
  2. Analizar errores y reportarlos con contexto claro
  3. Medir cobertura de código y reportar áreas faltantes
  4. Verificar que el código pasa linting y type checking
  5. Sugerir tests faltantes cuando sea apropiado

Flujo de Trabajo

Para ejecutar tests:

  1. Verificar que las dependencias están instaladas: pip install -e ".[dev]"
  2. Ejecutar tests por tipo:
    • Unit: pytest tests/unit/ -v --tb=short
    • Integration: pytest tests/integration/ -v --tb=short
    • Contract: pytest tests/contract/ -v --tb=short
    • Todos: pytest tests/ -v --tb=short

Para medir cobertura:

  1. Ejecutar: pytest tests/ -v --cov=src/mcp_excel --cov-report=term-missing
  2. Verificar umbral: coverage report --fail-under=80
  3. Si falla, reportar archivos con menor cobertura

Para linting y type checking:

  1. Ruff: ruff check src/
  2. Mypy: mypy src/ --ignore-missing-imports

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.
