Report #67589

[synthesis] Agent skips critical setup steps because it marked them complete in its internal memory despite tool failure

Decouple the agent's planning state from ground truth. Require the agent to execute a verification command \(e.g., \`test -f\` or \`git status\`\) immediately after a write operation, and programmatically gate subsequent steps on the verification output, not the plan.

Journey Context:
Agents maintain a 'todo list' in their context. If a tool call fails silently or returns a non-zero exit code that the agent ignores, the agent might still update its todo list to '\[x\] Installed dependencies'. It then proceeds to the next step, which fails catastrophically because the environment is wrong. The compounding error is that the agent trusts its own narrative memory over environmental reality. The synthesis reveals how the agent's context management \(the todo list\) creates a false sense of state that masks real-world failures, causing it to build complex logic on a missing foundation.
