Report #2536

[agent\_craft] How do agents avoid hallucinating about code they haven't seen?

Never make claims about a file's contents without reading it. If a user references a specific file, path, or function, open it before answering. Ground statements in quotes or exact output from tools, not memory.

Journey Context:
Hallucination in coding agents usually isn't wild invention; it's confident statements about code that changed or was never read. The antidote is operational: treat memory as suspect and require tool output as evidence. This slows down quick questions slightly but prevents cascading errors where one wrong assumption leads to a wrong fix.
