A diff cannot replay a Claude Code run
A Claude Code diff shows the final change, but it leaves out the starting state, failed commands, MCP results, skipped tests, and plan changes. Capture a compact replay record before the run disappears.

A Claude Code diff shows the final change, but it leaves out the starting state, failed commands, MCP results, skipped tests, and plan changes. Capture a compact replay record before the run disappears.
Claude Code can produce a clean patch from a messy run. Production teams need a flight recorder: the task contract, tool calls, permission pressure, tests, assumptions, and rollback notes that explain how the patch was made.
A latency chart will not explain why an AI answer was wrong. Production LLM systems need traces, sources, tool calls, prompt versions, eval results, and human decisions.
A Claude Code diff is not enough evidence for production review. Ask for the objective, permission boundary, tool trace, tests, failures, cost, and rollback path before approving agent work.

If a Claude Code agent changes production code, the useful artifact is not the chat transcript. It is a flight recorder: intent, boundaries, commands, diffs, tests, approvals, and rollback notes.
