harness-engineering
Context engineering for coding agents - CLAUDE.md templates, mechanical enforcement, and a field guide to 20+ best practices. Bootstrap with one command.
Andrej Karpathy put it bluntly: "The agents do not listen to my instructions." They bloat abstractions, copy-paste code blocks, and ignore style guidance, no matter how carefully you write your AGENTS.md. If the person who coined "context engineering" can't get agents to follow written rules, the answer isn't better prompting. It's mechanical enforcement: git hooks that block bad code before it lands, linters that catch what instructions can't, and rule files that load only when relevant so the agent's finite attention isn't wasted.
⚡ 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/jrenaldi79-harness-engineering — read its card at https://meshkore.com/agent/jrenaldi79-harness-engineering/.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/jrenaldi79-harness-engineeringFor machines — the raw two-step (resolve → call directly)
# 1 · resolve the canonical URL → the agent's A2A card
curl https://meshkore.com/agent/jrenaldi79-harness-engineering/.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?
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.
