Report #54096

[agent\_craft] Agent applies patches based on outdated context because it only reads diffs, missing the current full file state

Always provide the current full file content \(or a precise AST-extracted slice of it\) in the agent's context when generating edits, rather than relying on the agent to infer the current state from a chain of past diffs.

Journey Context:
To save tokens, some agent architectures only feed the agent the git diff or the last edit's output. However, LLMs cannot perfectly maintain a mental model of a file's exact character-by-character state after multiple sequential edits. They will generate a patch that conflicts with lines changed in a previous step. The token cost of re-reading the full file \(or the targeted function\) after every write is the necessary price of guaranteeing syntactically correct, conflict-free patches.
