Claude Code's Task tool sometimes doesn't resolve short aliases (opus,
sonnet, haiku) and passes them directly to the API, causing 404s. Tasks
then inherit the parent session's model instead of the configured one.
Added:
- MODEL_ALIAS_MAP in core.cjs mapping aliases to full model IDs
- resolve_model_ids config option (default: false for backward compat)
- resolveModelInternal() maps aliases when resolve_model_ids is true
Usage:
{ "resolve_model_ids": true }
This causes gsd-tools resolve-model to return 'claude-sonnet-4-5' instead
of 'sonnet', which the Task tool passes to the API without needing alias
resolution on Claude Code's side.
The alias map is maintained per release. Users can also use model_overrides
for full control.
All 755 tests pass.
