What Improve Harness does

Improve Harness guides one explicit, evidence-backed improvement to a repository's agent guidance, tools, runbooks, or validation after observed reusable agent friction. Use only when the user invokes $improve-harness or explicitly asks to improve the Harness.

Improve Harness is cataloged under AI Engineering on DirSkills. Improve Harness comes from a repository tagged agents-md, ai-agents, ai-assisted-development, claude-code and codex.

Documentation

README

Excerpt

Improve Harness

Improve one bounded future-agent behavior without turning every difficult task into permanent process. Keep consumer truth with its owner and require a fresh rerun before claiming improvement.

Establish Authority

Read AGENTS.md, docs/WORKFLOW.md, and applicable local instructions.
Confirm the request authorizes changing Harness behavior. Inspection or a request to report friction does not authorize edits.
Record the initial repository root, revision, branch, status, and unrelated changes. Preserve all existing work.
Treat invocation as authority for this bounded experiment, not for changing product policy, weakening proof, adding credentials, or mutating external systems.

This is the opening of the README. Read the full README on GitHub.
