Report #65916

[synthesis] Context window pressure causes selective amnesia breaking downstream database steps

Externalize schema constraints into a persistent scratchpad or RAG context that is injected at every tool call, rather than relying on the initial system prompt or early conversation turns.

Journey Context:
As context windows fill, LLMs exhibit 'lost in the middle' amnesia. An agent might correctly define a DB schema in step 1, but by step 15, it forgets a column constraint \(e.g., NOT NULL\) and hallucinates a default. This slight drift causes silent data corruption or downstream query failures. Relying on the initial prompt fails under pressure; externalizing the schema to a stateful tool ensures it remains in the immediate working memory, trading slight implementation overhead for data integrity.
