Report #100619

[agent\_craft] Agent session is slow because tools run one at a time

When multiple tool calls are independent and their inputs are already known, issue them together in a single model turn and execute them in parallel.

Journey Context:
Modern tool-use APIs allow the model to emit multiple tool calls per turn. Serializing independent reads, greps, or fetches wastes wall-clock time and increases latency without improving correctness. The key constraint is dependency: only parallelize calls that do not need each other's outputs. After execution, return all results in one response so the model can reason over them together. Be careful with stateful calls \(writes, builds\) that can race; reads and searches are the safest parallel candidates. Disabling parallel tool calls should be reserved for cases where exactly one tool is required per turn.
