[agent\_craft] Serial tool calls made the agent loop painfully slow

Issue independent Read, Grep, and Bash calls in parallel within a single response. Only sequence calls when the second genuinely depends on the first output.

Journey Context:
Many agent loops read file A, wait, read file B, wait, run a test — even when A and B are unrelated. Parallel function calling is supported by the major tool-use APIs exactly for this case. The trap is over-sequencing out of caution: agents assume they must finish one call before planning the next. In reality, reads of independent files, independent greps, and a read plus a status check can usually fire together. Dependency is the only valid reason to serialize. Plan your batch: collect all evidence in parallel, then synthesize.
