Report #64187

[synthesis] Agent uses wrong file paths after shell commands change working directory state

Always use absolute paths in all tool calls. Never rely on relative paths or assume the working directory is stable across tool invocations. If shell tools are used, explicitly capture and re-inject the cwd after every call, or design tool interfaces to accept and use absolute paths exclusively.

Journey Context:
Agents that mix file operations with shell commands face a state synchronization problem. A \`cd\` in one shell call doesn't persist to the next call in most agent frameworks because each tool invocation spawns a new subprocess. But the agent's internal model updates as if the directory change persists \(because it saw the \`cd\` command succeed\). This creates a path resolution mismatch: the agent thinks it's in \`/project/src\` but it's actually in \`/project\`. A relative path like \`utils/helper.py\` resolves to \`/project/utils/helper.py\` instead of \`/project/src/utils/helper.py\`. The agent reads the wrong file, modifies the wrong file, and by step 7 has corrupted data in a location it never intended to touch. The key insight is that this is not a path error — it's a state desynchronization between the agent's mental model and the actual execution environment, caused by the assumption that shell state persists across stateless tool calls.
