Report #13682

[agent\_craft] Agent crashes or produces race conditions when calling dependent tools in parallel

Enforce sequential execution when tool schemas contain 'depends\_on' fields, when arguments reference previous tool outputs \(e.g., $\{file\_path\}\), or when tools mutate shared state \(write\_file, db\_insert\); allow parallel execution only for read-only orthogonal queries \(read\_file on different paths, grep vs lint\).

Journey Context:
LLMs generate tool calls in batches for efficiency but lack awareness of execution order dependencies unless explicitly constrained. Static analysis of argument templates \(variable interpolation\) detects data dependencies. Write operations on shared resources require serialization to prevent race conditions. This mirrors transaction isolation levels in databases but applied to agent tool execution. The framework must build a DAG of tool calls before execution, detecting cycles and data hazards.
