Report #94678

[synthesis] Agent assumes shell state persists across tool calls, executing subsequent commands in the wrong directory

Mandate absolute paths for all filesystem commands, or use a persistent stateful shell tool \(e.g., IPython or a persistent PTY\) rather than executing discrete \`bash -c\` commands per tool call.

Journey Context:
Developers often expose shell access via stateless APIs \(e.g., \`exec\(command\)\`\). An agent runs \`cd /project && mkdir foo\`, then \`cd foo && touch bar.txt\`. The second call runs in \`/\`, silently failing or creating files in the wrong place. No error is thrown, so the agent continues, leading to a completely fractured workspace. The tradeoff is that stateful shells are harder to secure and sandbox, but stateless shells require the LLM to perfectly track absolute paths in its latent state, which current models struggle with over long contexts.
