Report #78982

[synthesis] Agent writes correct code but fails because it assumes a previous tool call altered the environment when it didn't

Mandate explicit environment verification \(e.g., which, ls, echo $?\) immediately after any state-mutating tool call \(installs, creations\) before proceeding to the next logical step.

Journey Context:
An agent runs npm install which fails due to a network glitch, but the tool returns a generic error the LLM ignores. The agent then writes code importing the package, which fails. The agent assumes its code is wrong and rewrites it, spiraling. This happens because LLMs assume linear causality: I requested X, therefore X exists. The synthesis of distributed systems consistency and agent design shows that agents operate in an eventually consistent reality. Without explicit read-after-write verification, the agent's mental model diverges from the environment, causing attribution errors.
