Re-implement PR #2690 against current upstream/dev since original
branch became incompatible with codebase refactoring.
Changes:
- Import loadUserAgents and loadProjectAgents from claude-code-agent-loader
- Merge user/project agents with server agents in resolveSubagentExecution()
- Server agents take precedence on name collisions
- Primary-mode agents from user/project are filtered out
Tests: 4 new test cases covering user agent resolution, project
agent resolution, server precedence, and primary agent filtering.
subagent-resolver: when falling back to matchedAgent.model for custom
subagents, verify the model is actually available via fuzzyMatchModel
before setting it as categoryModel. Prevents delegate_task from using
an unavailable model when the user's custom agent config references
a model they don't have access to.
Test updated to include the target model in available models mock.
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
- Hoist resolveFallbackChainForCallOmoAgent before sync/background branch
so sync executor also receives the fallback chain
- Add fallbackChain parameter to sync-executor with setSessionFallbackChain
- Mock connected-providers-cache in event.model-fallback tests for
deterministic behavior (no dependency on local cache files)
- Update test expectations to account for no-op fallback skip when
normalized current model matches first fallback entry
- Add cache spy isolation for subagent-resolver fallback_models tests
