cost-lean
Manage context profiles for lean sessions.
This skill helps you reduce context bloat by creating and managing profiles that
selectively enable/disable MCP servers and skills based on actual usage patterns.
Usage
The skill runs: node "${CLAUDE_PLUGIN_ROOT}/skills/cost-lean/scripts/lean.js" $ARGUMENTS
Available Commands
- (no args) or status - Show current context load breakdown with token
counts and costs for all skills/MCPs, plus what's currently disabled
- profiles - List all saved context profiles
- save - Save current active configuration as a named profile
- recommend - Analyze usage data and generate recommended profiles based on
actual usage patterns (lean, recent, project-specific)
- restore - Restore full configuration (re-enable all skills/MCPs)
Workflow
- Run
recommend to see what you're actually using
- Choose a recommended profile or save your own
- Tell the user to run
npx cost-lean --profile <name> before their next session
to apply the profile
- Profiles take effect on NEXT session start, not the current session
Examples
- "Show me my context load" → runs status
- "What profiles do I have?" → runs profiles
- "Save this as my work setup" → runs save work
- "Find what I actually use" → runs recommend
- "Go back to full config" → runs restore
