Harness defaults
New sessions with a harness start from its defaults. Leave a field on its default to inherit the harness’s own behavior.
Set defaults
- Open Settings > Agents > Harnesses.
- Open an installed harness and click Configure.
- Under Defaults, set the fields you want, for example model or permission mode. Use More settings for the rest.
- Click Save defaults.
The harness page also links to its saved roles, plugins and subagents. To preselect plugins, switch them to Default for <Harness> on the Plugins page.
Use Reset to defaults to clear your changes.
Where they apply
Every new session with that harness starts from these values. You can still change them in the session form. A role you pick overrides them for that session.
Defaults are stored in tyrn.harness_defaults.<harness_id> in settings, and in ~/.tyrn/defaults/<harness>.json.
