model: inherit in agent frontmatter causes ProviderModelNotFoundError; subagents hidden from /agents dialog #17890
Closed as not planned
Description
Description
Two related regressions affecting externally-installed subagents (e.g. get-shit-done):
- Agents with model: inherit in their frontmatter have inherit passed to Provider.parseModel(), producing { providerID: "inherit", modelID: "" }. Since the field is non-null, the ?? fallback in task.ts is skipped and the spawned session fails with ProviderModelNotFoundError.
- The /agents dialog only shows agents where mode !== "subagent", so any externally-installed subagent is invisible — even though the agents load correctly and appear in permission logs.
Plugins
N/A
OpenCode version
1.2.27-cb69501
Steps to reproduce
- Install get-shit-done for OpenCode.
- Try to use any get-shit-done command, see spawned subagents failed with ProviderModelNotFoundError.
- Open /agents and see none of the installed agents.

downgrade to GSD v1.23.0, GSD v1.24.0 introduces this issue, or go and put a valid name in your GSD agent configurations, valid model names are: https://models.dev/model-schema.json#/$defs/Model

Subagents are not meant to show up in the modal dialogue that the
/agentscommand produces as they cannot be selected for use.flacks commentedon Mar 17, 2026
Agreed, updated.

Fantastic! My previous thumbs down react has now been replaced with a thumbs up since this now appears to be a straightforward bug fix.
