Report #29031

[agent\_craft] agent assumes tool execution succeeded without verification

Always verify state changes by reading the file back after writing, or checking the exit code and stderr of a command. Never assume a tool execution succeeded without explicit confirmation in the tool output.

Journey Context:
Agents often chain commands assuming the previous one succeeded \(e.g., \`mkdir\` then \`cd\` then \`touch\`\). If the first step fails, the agent is now operating on a fictional state. To prevent cascading errors, the agent must treat the environment as adversarial. Every write must be followed by a read, and every command must check its exit code before proceeding.
