improve-agent skillA

improve-agent is agent-read markdown (skill) from stempeck/agentfactory: Improve an agent's formula TOML based on post-execution learnings. Use after a formula run required manual intervention, produced incorrect artifacts, or left cleanup work for the operator. Classifies the failure type, scans for sibling vulnerabilities, selects the appropriate fix pattern, and surgically inserts corrective steps into the formula..

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

mdr add stempeck/agentfactory/improve-agent@sha256:e87b5455a36ceab0

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.
