Зачем использовать

Ключевые функции

Pairwise/N-wise test generation
Constraint syntax (IF/THEN parameter rules)
Translates plain-English parameter descriptions into pict models
Outputs test cases as a table or as test code skeletons

Установка

Выберите клиент

~/Library/Application Support/Claude/claude_desktop_config.json · Windows: %APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "pypict-claude-skill": {
      "command": "git",
      "args": [
        "clone",
        "https://github.com/omkamal/pypict-claude-skill",
        "~/.claude/skills/pypict-claude-skill"
      ],
      "_inferred": true
    }
  }
}

Откройте Claude Desktop → Settings → Developer → Edit Config. Перезапустите после сохранения.

~/.cursor/mcp.json · .cursor/mcp.json

{
  "mcpServers": {
    "pypict-claude-skill": {
      "command": "git",
      "args": [
        "clone",
        "https://github.com/omkamal/pypict-claude-skill",
        "~/.claude/skills/pypict-claude-skill"
      ],
      "_inferred": true
    }
  }
}

Cursor использует ту же схему mcpServers, что и Claude Desktop. Конфиг проекта приоритетнее глобального.

VS Code → Cline → MCP Servers → Edit

{
  "mcpServers": {
    "pypict-claude-skill": {
      "command": "git",
      "args": [
        "clone",
        "https://github.com/omkamal/pypict-claude-skill",
        "~/.claude/skills/pypict-claude-skill"
      ],
      "_inferred": true
    }
  }
}

Щёлкните значок MCP Servers на боковой панели Cline, затем "Edit Configuration".

~/.codeium/windsurf/mcp_config.json

{
  "mcpServers": {
    "pypict-claude-skill": {
      "command": "git",
      "args": [
        "clone",
        "https://github.com/omkamal/pypict-claude-skill",
        "~/.claude/skills/pypict-claude-skill"
      ],
      "_inferred": true
    }
  }
}

Тот же формат, что и Claude Desktop. Перезапустите Windsurf для применения.

~/.continue/config.json

{
  "mcpServers": [
    {
      "name": "pypict-claude-skill",
      "command": "git",
      "args": [
        "clone",
        "https://github.com/omkamal/pypict-claude-skill",
        "~/.claude/skills/pypict-claude-skill"
      ]
    }
  ]
}

Continue использует массив объектов серверов, а не map.

~/.config/zed/settings.json

{
  "context_servers": {
    "pypict-claude-skill": {
      "command": {
        "path": "git",
        "args": [
          "clone",
          "https://github.com/omkamal/pypict-claude-skill",
          "~/.claude/skills/pypict-claude-skill"
        ]
      }
    }
  }
}

Добавьте в context_servers. Zed перезагружается автоматически.

claude mcp add pypict-claude-skill -- git clone https://github.com/omkamal/pypict-claude-skill ~/.claude/skills/pypict-claude-skill

Однострочная команда. Проверить: claude mcp list. Удалить: claude mcp remove.

Сценарии использования

Реальные сценарии: pypict Test Case Generator

Cover a feature with combinatorial inputs without writing 64 tests

👤 QA + devs writing integration tests ⏱ ~15 min intermediate

Когда использовать: Feature has 4+ enum-ish parameters and exhaustive testing would explode.

Предварительные требования

Server/skill installed and authenticated — See repo README

Поток

Model

Use pypict skill: model checkout with payment_method=[card, paypal, applepay], shipping=[standard, express, intl], discount=[none, code, member], currency=[USD, EUR].✓ Скопировано

→ Pict model + ~12 pairwise cases
Generate tests

Emit pytest tests from those cases against checkout().✓ Скопировано

→ pytest file with parametrize

Итог: Real combinatorial coverage with ~12 cases instead of 81.

Подводные камни

Pairwise misses higher-order bugs (3-way interactions). For safety-critical paths, use 3-wise. — Pairwise misses higher-order bugs (3-way interactions). For safety-critical paths, use 3-wise.

Стоимость и лимиты

Во что обходится

Квота API: See provider docs for rate limits
Токенов на вызов: Varies by tool
Деньги: See repo README for pricing details
Совет: Cache tool results and avoid repeated identical calls.

Безопасность

Права, секреты, радиус поражения

Хранение учётных данных: Use environment variables; never commit secrets

Исходящий трафик: Tool calls go to the provider's API as documented

Устранение неполадок

Частые ошибки и исправления

pict binary not found

Install Microsoft's pict tool (or pypict bundles it). See pypict README.

Проверить: pypict.exec_pict('test')

constraints rejected

pict constraint syntax is strict: IF [A] = "x" THEN [B] <> "y";. Use the skill's validator.

Проверить: Run validator first
