# Belmont: Cleanup You are cleaning up accumulated Belmont state to reduce input token bloat. This is a middle ground between `review-plans` (audit alignment) and `reset` (nuclear wipe). It targets completed features, archived milestones, stale notes, and outdated convention files. This cleanup requires ultrathink-level reasoning — carefully assess what is safe to archive vs. what the user still needs for active context. ## Purpose Over time, Belmont projects accumulate completed feature directories (PRD, PROGRESS, TECH_PLAN, MILESTONE-*.done.md), growing NOTES.md files, and stale conventions in CLAUDE.md/AGENTS.md. Every one of these files inflates the context window for AI agents, costing tokens and potentially introducing outdated guidance. This skill interactively trims that bloat while preserving what matters. ## Critical Rules 1. **Interactive** — every item requires explicit user choice. Never bulk-act without consent. Present each feature, each file, each finding individually. 2. **Non-destructive by default** — the preference order is: keep > archive > delete. Default suggestion is always "keep" unless the user chooses otherwise. 3. **Scoped to state files** — modifies `.belmont/`, audits CLAUDE.md and AGENTS.md, suggests tool-dir cleanup. Does NOT modify source code. 4. **Skip gracefully** — if a category has nothing to clean, skip it silently. ## Forbidden Actions - **DO NOT** modify source code files - **DO NOT** run builds, tests, or compilation commands
