[synthesis] Decoupled sequential tool calls mask dependency failures causing agents to debug symptoms instead of root causes

Bundle sequential dependencies into a single atomic shell script tool call, or implement strict exit-code propagation that halts the agent's planning loop on failure.

Journey Context:
Agents often execute 'npm install' and then 'npm run build' as separate tool calls. If the install fails \(e.g., network timeout, exit code 1\), the agent's orchestration layer might still proceed to the build step because the tool call 'completed'. The build fails with missing modules, and the agent spends iterations trying to fix the package.json or source code, completely unaware the install failed. The error compounds because the agent assumes prior steps succeeded. Atomic execution prevents this by tightly coupling the dependency chain.
