The author built four Claude Code mods to address common AI coding frustrations: secret-guard hides API keys from output, done-gate warns when tasks are marked complete without testing, plan-meter displays progress above the prompt, and context-meter shows context window usage. These mods run inside Claude Code’s process, unlike traditional hooks that launch separate processes, resulting in up to 100× less overhead. Built from session history analysis, the mods were tested with 135 passing tests.
Between August and October 2026, the author repeated secret warnings in 20 of 60 sessions and observed 408 plan file edits across 27 sessions. The mods offer a more reliable, automated alternative to manual reminders and chat-based instructions.
