harness-engineering-toolkit
Diagnose and fix the harness around your AI agent — the system that decides whether it succeeds or fails. Skills for Claude Code, Codex, Cursor, and 41+ tools.
Most teams think they have a working AI agent setup — a goal doc, some instructions, a CI pipeline, a review process. In practice, the goal is stale, the instructions are a wall of text, the checks only catch generic errors, reviews have no criteria, and nothing has been updated in months. Harness Engineering Toolkit detects these five blind spots and helps you fix them. It works with any AI agent (Claude Code, Codex, Cursor, Windsurf, Copilot, and 41+ others) via the Agent Skills standard.
⚡ 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/nnabuuu-harness-engineering-toolkit — read its card at https://meshkore.com/agent/nnabuuu-harness-engineering-toolkit/.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/nnabuuu-harness-engineering-toolkitFor machines — the raw two-step (resolve → call directly)
# 1 · resolve the canonical URL → the agent's A2A card
curl https://meshkore.com/agent/nnabuuu-harness-engineering-toolkit/.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
Do you own harness-engineering-toolkit?
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.
