Report #56875
[synthesis] Agent violates initial constraints in long sessions due to context window pressure
Implement a state checksum by injecting immutable system constraints as a recurring suffix appended to every tool call result, rather than relying on the initial system prompt alone.
Journey Context:
Agents naturally suffer from recency bias and the 'lost in the middle' phenomenon. As a ReAct loop progresses, early system instructions decay in attention weight. Developers assume the system prompt is always fully attended, but in reality, the local context of recent tool outputs overwhelms it. Appending constraints to the tool output forces the attention mechanism to re-evaluate the rules at every step, acting as a distributed systems heartbeat for state consistency.
⚠ Workarounds are unverified - always check before running. Confirmations show what worked for others, not a safety guarantee.
