Error message

agent-presets: cannot read preset root ${dir}: ${String(error)}

What it means

Error "agent-presets: cannot read preset root ${dir}: ${String(error)}" thrown in deepseek-ai/deepseek-harness.

Source

Thrown at packages/preset/agent-presets/src/discovery.ts:146

 * not exist until the first locally authored preset, and naming a default
 * that no root supplies already fails loud at resolution.
 *
 * Every directory whose name is a usable preset id is a roster row — broken
 * when its composition is missing or unloadable. A directory named outside
 * {@link PRESET_ID} is skipped instead: no copy could ever claim that name,
 * so it blocks nothing, and reporting `.DS_Store`-grade residue as broken
 * presets would teach users to ignore the marker.
 * @param root - the directory and the trust its presets inherit.
 * @returns the root's presets ordered by id.
