ag2-testing

ag2ai/build-with-ag2/.agents/skills/ag2-testing/SKILL.md

Test AG2 beta agents and tools without hitting a real LLM provider. Pass `TestConfig(...)` from `autogen.beta.testing` as the agent's config (or per-`ask`) to mock LLM responses, inject `ToolCallEvent`s to simulate tool execution, and assert success / error paths. Use when the user is writing pytest tests for an Agent or Tool.

idavidov13Reads credentialsSkill

api-testing

idavidov13/agentic-playwright/.claude/skills/api-testing/SKILL.md

API testing patterns for Playwright -- apiRequest fixture usage, Zod response schema creation and validation, test.step wrapping for multi-call tests, per-field negative/validation testing, path parameter fuzzing, and helper fixtures for shared setup/teardown. Use when writing or updating API test specs, adding tests for a new endpoint, creating Zod schemas for responses, wiring apiRequest or helper fixtures, or investigating API behavior mismatches vs the OpenAPI spec. Do NOT use for UI selectors (use the page-objects or selectors skill) or for generic Playwright fixture authoring unrelated to API setup/teardown (use the fixtures skill).
