TDD-style testing methodology for skills using fresh subagent instances to prevent priming bias and validate skill effectiveness. Use when validating skill improvements, testing skill effectiveness, preventing priming bias, measuring skill impact on behavior. Do not use when implementing skills (use skill-authoring instead), creating hooks (use hook-authoring instead).
Tests skills using fresh Claude instances to prevent priming bias and validate effectiveness.
/plugin marketplace add athola/claude-night-market/plugin install abstract@claude-night-marketThis skill inherits all available tools. When active, it can use any tool Claude has access to.
modules/testing-patterns.mdTest skills with fresh subagent instances to prevent priming bias and validate effectiveness.
Fresh instances prevent priming: Each test uses a new Claude conversation to verify the skill's impact is measured, not conversation history effects.
Running tests in the same conversation creates bias:
Three-phase TDD-style approach:
Test without skill to establish baseline behavior.
Test with skill loaded to measure improvements.
Test skill's anti-rationalization guardrails.
# 1. Create baseline tests (without skill)
# Use 5 diverse scenarios
# Document full responses
# 2. Create with-skill tests (fresh instances)
# Load skill explicitly
# Use identical prompts
# Compare to baseline
# 3. Create rationalization tests
# Test anti-rationalization patterns
# Verify guardrails work
For complete testing patterns, examples, and templates:
Activates when the user asks about AI prompts, needs prompt templates, wants to search for prompts, or mentions prompts.chat. Use for discovering, retrieving, and improving prompts.
Search, retrieve, and install Agent Skills from the prompts.chat registry using MCP tools. Use when the user asks to find skills, browse skill catalogs, install a skill for Claude, or extend Claude's capabilities with reusable AI agent components.
Creating algorithmic art using p5.js with seeded randomness and interactive parameter exploration. Use this when users request creating art using code, generative art, algorithmic art, flow fields, or particle systems. Create original algorithmic art rather than copying existing artists' work to avoid copyright violations.
