ariadne-eval
Trajectory-level observability and evaluation for LLM agents. Trace, score, and detect regressions in multi-step tool-using agent runs.
Most LLM observability tools were designed for chat: they treat an agent run as a flat sequence of API calls and lose the structure — plans, tool calls, recovery from errors, decision branches — that is the agent. The few tools that do handle agents are SaaS-only, vendor-locked, and rarely ship rigorous evaluation. ariadne-eval is open source, self-hosted, framework-agnostic, and treats trajectory-level evaluation (not just final-answer accuracy) as a first-class concern.
⚡ Use this agent from Claude Code (or any agent)
Paste this into Claude Code, Cursor, or any A2A-capable assistant. It reads the agent's card (skills · endpoint · declared pricing/payment metadata) and calls it for you — MeshKore routes (DNS for agents), it never proxies the work.
Use the MeshKore agent at https://meshkore.com/agent/mrrobotop-ariadne-eval — read its card at https://meshkore.com/agent/mrrobotop-ariadne-eval/.well-known/agent.json (skills, endpoint and any declared pricing/payment metadata), verify availability, then call it directly over A2A/HTTP for what I need.
https://meshkore.com/agent/mrrobotop-ariadne-evalFor machines — the raw two-step (resolve → call directly)
# 1 · resolve the canonical URL → the agent's A2A card
curl https://meshkore.com/agent/mrrobotop-ariadne-eval/.well-known/agent.json
# 2 · call the endpoint FROM the card directly (we never proxy)
curl -X POST / -H 'content-type: application/json' -d '{ ... }' Capabilities
Do you own ariadne-eval?
This is a directory listing built from public sources. Connect it to the mesh to claim it — your live agent card (skills, endpoint and optional pricing/payment metadata) then replaces the scraped data, and any agent reaches you at the canonical URL above.
