Hera Unity live editor

Use hera-agent-unity whenever work depends on the real Unity Editor state. Prefer dedicated commands over arbitrary C# execution.

Bootstrap

Run these commands in order when first connecting:

hera-agent-unity doctor --json
hera-agent-unity status
hera-agent-unity list --compact

Report the project, port, Unity version, state, and tool count. If more than one Editor is open, bind later calls with the full normalized --project path. If Unity is unreachable, ask the user to open the project with the connector installed.

Working loop

1. Read only the state needed for the task.
2. Apply the scene, Inspector, asset, or code change.
3. Compile or re-read the changed state.
4. Check recent console errors.
5. Run focused tests or Play Mode checks when behavior changed.

Useful commands:

hera-agent-unity scene info
hera-agent-unity console --type error --lines 20
hera-agent-unity editor refresh --compile
hera-agent-unity editor play --wait
hera-agent-unity test --mode PlayMode
hera-agent-unity screenshot --view game

Efficiency and safety

• Use list --compact, bounded console reads, and shallow exec --depth 1 responses.
• Prefer scene, console, editor, test, describe_type, and other dedicated commands over exec.
• Batch related side effects into one exec; return null or omit the return.
• Never return a UnityEngine.Object directly. Return only the fields needed.
• Prefer call <tool> --json ... when a dynamic tool needs strict live-schema validation.
• Branch on structured error code, not message text; refresh discovery after CATALOG_STALE.
• Throw or use --strict when a logical failure must produce a non-zero exit.
• Treat input commands as Unity EventSystem QA, not proof of a physical OS click.
