agent-harness-design skillA

agent-harness-design is agent-read markdown (skill) from yeaight7/agent-powerups: Use when designing tool definitions for a new agent or subagent, an agent shows high retry rates, ambiguous tool invocations, or silent failures, or an existing agent harness needs a quality review..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version
mdr add yeaight7/agent-powerups/agent-harness-design@git:20260606.a592844
Exact content
mdr add yeaight7/agent-powerups/agent-harness-design@sha256:97f95d471ee1815a

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
