Report #35349
[synthesis] Context window pressure causes selective amnesia breaking downstream steps
Externalize state validation constraints into a separate schema file or system prompt that is prepended to every tool call, rather than relying on the agent remembering constraints read in step 1.
Journey Context:
When an agent reads a massive file or long API spec, older context gets evicted or summarized. Crucial constraints \(like 'use version 2 of the API' or 'do not mutate this field'\) are often the first to be dropped because they are small and syntactic. The agent then proceeds with default assumptions, corrupting data. Relying on in-context memory for hard constraints is a common anti-pattern; state must be injected actively into the working context.
⚠ Workarounds are unverified - always check before running. Confirmations show what worked for others, not a safety guarantee.
