[agent\_craft] The agent re-reads the same files repeatedly instead of caching extracted facts

After reading a file, extract and store structured facts in a working-memory scratchpad keyed by path and version. Subsequent turns should reference the scratchpad unless the file changed or a new question requires a re-read.

Journey Context:
Read operations are cheap in token terms but expensive in context and latency. A common anti-pattern is re-running grep or cat on every turn because the agent no longer trusts its own previous summary. The fix is a read-through cache with explicit versioning: the first read produces a structured note, and later turns use the note. Re-read only when the file hash changes, when the note is insufficient for a new task, or when the agent detects inconsistency. This sounds obvious but requires discipline: the agent must label each stored fact with its source and confidence, otherwise the cache becomes a fiction generator.
