Over the past month or so, I have released three reinforcement tools for Claude Code on npm.

Throughline — Offloads bloated context.

Caveat — Surfaces past notes so you don't step into the same trap twice.

Spotter — A separate Claude audits missed tool calls.

Each solves a different problem, but the root cause is the same: all the problems that could be fixed by telling Claude to "be careful" had already been fixed. What remained were issues that could not be fixed structurally.
