Drop the old agent EventBus, SubscribeEvents/EventDrops public surface, legacy hook observer dispatch, and hook.event process notification path. Agent observations now flow through pkg/events runtime events.
Validation: go test ./pkg/agent; make lint
Migrate hook observation to runtime events and update the process hook notification protocol. Add runtime event publication for message bus failures, channel lifecycle/outbound flow, gateway reloads, MCP server state, and MCP tool calls.
Validation: go test ./pkg/events/... ./pkg/bus ./pkg/agent ./pkg/channels ./pkg/mcp ./pkg/tools/integration ./pkg/gateway; make lint
Introduce pkg/events with filtered channels, subscription policies, backpressure, and stats. Wire AgentLoop to dual-publish legacy agent events into runtime events while preserving old event APIs.
Validation: go test ./pkg/events/... ./pkg/agent; go test -race ./pkg/events/...; make lint
Resolves conflicts after the agent loop refactor on main:
- pkg/agent/loop.go was deleted upstream (logic split into agent.go,
agent_init.go, pipeline.go, etc.); accepted the deletion.
- Moved the delegate tool registration block from the old loop.go
into registerSharedTools in pkg/agent/agent_init.go, immediately
after the spawn/spawn_status block. Logic and gating
(len(registry.ListAgentIDs()) > 1) are unchanged.
- pkg/agent/subturn.go and pkg/agent/subturn_test.go merged cleanly
on their own; TargetAgentID field, validation, registry lookup,
and tests all preserved.
Verified locally:
- go build ./pkg/agent/... ./pkg/tools/... clean
- go vet clean
- TestDelegateTool* (17 cases) pass
- TestSpawnSubTurn_TargetAgentID_* (3 cases) pass
- TestDelegateToolRegistered_MultiAgent / _SingleAgent pass
- full pkg/agent + pkg/tools test suites green
- centralize web search provider readiness and resolution logic
- fall back when the configured provider is unavailable or invalid
- allow native-search-capable models to use built-in search without the client tool
- simplify the tools page and add direct access to web search settings
- add backend, agent, and integration tests for the new selection behavior
