claude-slim
You're burning thousands of tokens before you even say "hello."
Every Claude Code session auto-loads every skill, memory file, and plugin instruction into the system prompt — even the ones you never use. If you run OMC, marketplace plugins, or a custom skill stack, you're paying for context you'll never touch. claude-slim finds and removes that waste.

Where the bloat hides:
| Source | Typical overhead |
|---|
| 60+ registered skills | ~3,000 tokens |
| CLAUDE.md (plugin instructions) | ~5,000 tokens |
| Memory files | ~2,500 tokens |
| Deferred tools list | ~1,500 tokens |
| Total | ~12,000 tokens |
That's slower responses. Hitting your usage cap faster. Paying for context you're not using.
One command. Five steps.

Scan — Measures everything: local skills, plugin skills, CLAUDE.md, memory files, MCP servers. Token counts are measured with js-tiktoken, not guessed.
Classify — Finds the waste automatically:
| What it catches |
|---|
| Broken symlinks | Dead links from uninstalled skill packs |
| Duplicates | Same skill registered from multiple sources |
| Empty templates | Placeholder skills with no content |
| Oversized files | SKILL.md over 10KB |
| Unused skills | Local skills never invoked in your last N days of sessions (default 60d) |
| Stale memory | Large memory files loaded every session |
| Disabled plugins | Installed but disabled plugins still in cache |
| Stale projects | Project memory untouched for 90+ days |
| Temp caches | Failed plugin install remnants (temp_local_*) |
Propose — Three tiers, you decide:
| Tier | Action | Example |
|---|
| Auto | Pre-selected | Broken symlinks, empty templates, temp caches |
| Recommended | Suggested | Duplicates, stale memory, disabled plugins, stale projects |
| Optional | Your call | Oversized skills you might still use |
Clean — Moves selected items to ~/.claude/skills.disabled/. Nothing is deleted. Ever.
Report — Shows exactly what changed:
