Ranked by relevance
Your agent automatically executes the skill with parameters. Ultra-fast utility skills (~1ms) or AI-powered prompt skills (~2-5s).
Every execution returns exact cost ($0.0001 for utility, $0.001 for prompt). No surprises, full transparency.
Track execution history, monitor performance, and optimize your agent's skill usage over time.
