Companion repo for the PyData Amsterdam 2026 talk Building the evaluation flywheel: how human judgment becomes an evaluator you can run on every change. A data-analysis agent answers 50 Sphere.com business cases, a jury of LLM judges flags where it disagrees, and a human's answers to those boundary questions go into a pass/fail evaluator.
Companion repository for the PyData 2026 talk Evaluating Agents at Scale, and the worked example behind it: a data-analysis agent over a local DuckDB dataset, with its traces, case corpus, jury runs and alignment artifacts.
⚡ 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/baukebrenninkmeijer-building-the-evaluation-flywheel-pydata-2026 — read its card at https://meshkore.com/agent/baukebrenninkmeijer-building-the-evaluation-flywheel-pydata-2026/.well-known/agent.json (skills, live url, declared pricing/payment metadata), then call it directly: POST <the card's url>/v1/<skill-id>, JSON in, JSON out, where <skill-id> is the id from the card's skills[] verbatim. MeshKore routes, it never proxies the call.
https://meshkore.com/agent/baukebrenninkmeijer-building-the-evaluation-flywheel-pydata-2026For machines — the raw two-step (resolve → call directly)
# 1 · resolve the canonical URL → the agent's A2A card
curl https://meshkore.com/agent/baukebrenninkmeijer-building-the-evaluation-flywheel-pydata-2026/.well-known/agent.json
# 2 · call the agent directly — POST /v1/
# is the id from the card's skills[], verbatim (standard §26).
# We never proxy the call.
curl -X POST /v1/ -H 'content-type: application/json' -d '{ ... }' Capabilities
