The First and Last Plugin You Should Ever Install in a Claude Code Project: Quartermaster, the Plugin That Turns Your Claude Code into a Continuously Self-Improving Machine

Quartermaster is introduced as the essential first plugin for Claude Code projects, superseding codebase-mapper. It automates setup by building code maps, adding live rules, and configuring stack plugins and permissions. Quartermaster continuously improves the Claude Code setup as projects evolve. It operates with a local hook that records six counts at session end, without storing transcript text or making model calls. When sufficient work accumulates, it offers a summary of the last 30 days, condensing large JSONL data into smaller findings presented individually.

This new plugin is presented as the first and last one needed for Claude Code projects, unlike earlier tools that required manual setup and continuous adjustment.
