[synthesis] Context poisoning cascades across steps
Implement a validation layer that checks tool outputs against expected schemas and logical constraints before appending to the agent's context history.
Journey Context:
A minor hallucination in step 2 \(e.g., assuming a wrong file path\) gets fed back into the context as a tool output or 'observation' in step 3. The agent then uses this poisoned context to make further calls, creating a cascade. The synthesis of the ReAct observation model and AutoGPT context corruption issues reveals that agents lack semantic validation of tool outputs before injecting them back into context. Simply truncating context doesn't fix this; the poisoned data must be caught before it becomes an established 'fact' in the agent's working memory.
⚠ Workarounds are unverified - always check before running. Confirmations show what worked for others, not a safety guarantee.
