When you change the MCP server / API surface, add or update an integration test in tests/integration/. The integration-test-guard hook blocks git push when the outgoing commits touch API/MCP source without one (override with SKIP_ITEST_GUARD=1 only when a test genuinely does not apply).
Integration Test Guard is a community-contributed Claude Code skill in the testing sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/integration-test-guard/ and loads when your prompt matches the skill's trigger.
When to invoke it: Use when you modify the MCP server, tool definitions/handlers, the OpenAPI schema, the TD HTTP client, the transport layer, or the TD-side Python API (src/api, src/features/tools, src/server, src/tdClient, src/transport, td/modules/mcp). Also triggered by the integration-test-guard PreToolUse hook, which blocks a `git push` whose outgoing commits touch those paths without a tests/integration change.
The Integration Test Guard Claude Code skill is built for software engineers, backend developers, full-stack teams, and technical leads building and maintaining production systems. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 191,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
