feat(agent): enable opt-in parallel tool execution (#2716) - #19
Merged
Conversation
AgentEngine.executeToolCalls already branches to executeToolCallsParallel when AgentConfig.ParallelToolCalls is set, and that branch is fully implemented (errgroup, ordered result collection, best-effort siblings). But nothing ever set the flag: buildAgentConfig copies CustomAgentConfig into the runtime AgentConfig field by field, and this field was missing from both structs' bridge. The gate therefore always read the zero value, making executeToolCallsParallel unreachable for every custom agent. Add ParallelToolCalls to CustomAgentConfig and map it in buildAgentConfig. Defaults to false: tools are not required to be side-effect free, so agents saved before this option existed must keep running their tools sequentially. Enabling concurrency for them silently would be a behavior change rather than a fix.
Port Tencent#2716 onto the current fork staging branch using GitHub's three-way merge.

Scope
Port Tencent#2716 onto current
main.The Agent engine already implements parallel tool execution, but
CustomAgentConfignever propagated the flag into runtimeAgentConfig. This adds the missing opt-in bridge and tests.false, preserving existing sequential behavior.No schema migration and no default behavior change.
