Report #53596

[synthesis] Context window summarization causes agent amnesia, leading to non-idempotent destructive tool calls \(e.g., overwriting or dropping existing resources\)

Externalize state mutations to an append-only ledger outside the LLM context, and enforce idempotency constraints \(e.g., IF NOT EXISTS\) in all generated tool calls or scripts, regardless of the agent's belief about current state.

Journey Context:
When context is truncated or summarized, the agent loses track of side effects. It then re-executes initialization steps. If the tool is a shell command or SQL query that fails on duplicates or overwrites, the agent crashes or destroys data. Developers try to fix this by improving summarization, but summarization is lossy by definition. The robust fix is to assume amnesia is inevitable: all tool calls must be idempotent, and state must be verified via a read-before-write ledger, not relied upon from memory.
