Testing Layers:

Layer	What it Tests	Speed
L1 Structure	Plugin spec compliance, naming, cross-references	~0.1s
L2 Triggers	Skill description accuracy (precision/recall)	~30s/query
L3 Sessions	Multi-turn routing, context handling, boundaries	2-3 min
L4 Value	Does the skill actually help? (with vs without)	5+ min

Command: /copilot:copilot-plugin

Skill: copilot-plugin — Builds Copilot CLI plugin components: skills, agents, prompts, custom instructions, path-specific instructions, AGENTS.md routing, MCP servers, and hooks.

Includes reference specs for all Copilot CLI conventions, comparison matrices, a writing guide, and output templates.

---

cadre

Multi-agent team bootstrapper that analyzes your codebase and generates tailored agent teams via AI debate.

Command: /cadre:init

Skill: init — Analyzes project structure, runs an AI debate to determine optimal team composition, and generates .claude/agents/*.md files, config, and routing rules. Handles both existing projects and greenfield bootstrapping.
