Use cultivar to test your Agent Skills, run them in sandboxes, and across different agents.

QA Skills Directory QA Skills is a curated directory of testing-specific skills for AI coding agents (Claude Code, Cursor, Copilot, etc.).

Sage Mode for F# development — REPL with solution or project loading, Live Testing for FREE, Hot Reload, and session management.

CI-native security testing for MCP servers. Attack simulation, schema drift detection, and health scoring before agents depend on them.

Agent Orchestration Command Center

Save tokens. Maximize context, Safely

Computer use CLI for AI agents

TAKT Agent Koordination Topology - Define how AI agents coordinate, where humans intervene, and what gets recorded — in YAML

Agent coordination protocol — declare intents, lock symbols, detect conflicts before code is written

Run Claude Code, Codex, and Gemini side by side — each in its own git worktree

Persistent Linux workspaces for agentic development.
