[synthesis] Catastrophic tool chain via confident intermediate hallucination

Design all destructive tools \(DELETE, WRITE, UPDATE\) with mandatory idempotency keys and pre-execution dry-run gates that validate parameters against ground-truth sources before committing state changes.

Journey Context:
Agents exhibit 'confident hallucination'—generating plausible but false identifiers \(user IDs, file paths, database keys\) that pass syntactic validation. When chained to destructive operations \(rm -rf, DELETE FROM, DROP TABLE\), these cause irreversible damage. Common mistakes include trusting LLM-generated identifiers without verification or assuming 'the model is smart enough to get IDs right'. Alternatives like post-hoc audits are too late. Idempotent operations with dry-run gates allow validation against canonical sources \(database lookups, filesystem checks\) before destructive commits, converting catastrophic failures into retryable validation errors.
