- fix(switcher): use lastIndexOf for multi-slash model IDs (e.g. aws/anthropic/claude-sonnet-4)
- fix(model-resolution): same lastIndexOf fix in doctor parseProviderModel
- fix(call-omo-agent): resolve model from agent config and forward to both
background and sync executors via DelegatedModelConfig
- fix(subagent-resolver): inherit category model/variant when agent uses
category reference without explicit model override
- test: add model override forwarding tests for call-omo-agent
- test: add multi-slash model ID test for switcher
When provider-models cache is cold (first run / cache miss),
resolveModelForDelegateTask returns {skipped: true}. Previously this
caused the subagent resolver to:
1. Ignore the user's explicit model override (e.g. explore.model)
2. Fall through to the hardcoded fallback chain which may contain
model IDs that don't exist in the provider catalog
Now:
- subagent-resolver: if resolution is skipped but user explicitly
configured a model, use it directly
- subagent-resolver: don't assign hardcoded fallback chain on skip
- category-resolver: same — don't leak hardcoded chain on skip
- general-agents: if user model fails resolution, use it as-is
instead of falling back to hardcoded chain first entry
Closes#2820
Add support for object-style entries in fallback_models arrays, enabling
per-model configuration of variant, reasoningEffort, temperature, top_p,
maxTokens, and thinking settings.
- Zod schema for FallbackModelObject with full validation
- normalizeFallbackModels() and flattenToFallbackModelStrings() utilities
- Provider-agnostic model resolution pipeline with fallback chain
- Session prompt params state management
- Fallback chain construction with prefix-match lookup
- Integration across delegate-task, background-agent, and plugin layers
- #2741: Pass inheritedModel as fallback in subagent-resolver when user hasn't
configured an override, ensuring custom provider models take priority
- #2648: Fix getPlanProgress to treat plans with 0 checkboxes as incomplete
instead of complete (total > 0 && completed === total)
- #2779: Relax Hephaestus single-task guard to accept multi-step sub-tasks
from Atlas delegation, only rejecting genuinely independent tasks
Fixes#2741, fixes#2648, fixes#2779
- Add normalizeModelFormat() utility for string/object model handling
- Update subagent-resolver to handle both model formats
- Add explicitUserConfig flag to ModelResolutionResult
- Set explicitUserConfig: true when user model is found in pipeline
This fixes the issue where plugin-provided models fail cache validation
and fall through to random fallback models.
- Create available-models.ts for model availability checking
- Create model-selection.ts for category-to-model resolution logic
- Update category-resolver, subagent-resolver, and sync modules to import
from new focused modules instead of monolithic sources
