sipcode-regress

Check the user's own local Claude Code and Codex logs for regressions after an update (prompt-cache misses, 5-minute cache TTL, uncached context, hourly cache rebuilds, Codex usage limit draining faster per token) and pin each one to the version that introduced it, using the Sipcode CLI. Use when the user asks whether Codex or Claude Code got worse or more expensive after an update, why their usage limit burns faster than before, or whether an update changed their costs.
