Skill Value Report

Show whether each installed skill is earning the context-window tokens it costs.

Overview

Combine token cost and usage tracking into a single view of every installed skill, sorted with the heaviest unused skills at the top. The report splits each skill's cost into what is permanently loaded (the description) and what only loads on demand (the body), then cross-references recent invocations so the user can see which skills are dead weight.

Replaces the v1.2 split between /janitor-tokens (cost only) and /janitor-usage (usage only).

Prerequisites

• Claude Code with the skills-janitor plugin installed (provides scripts/value.sh)
• bash 3.2+ (the stock macOS bash works; no external dependencies)
• Read access to ~/.claude/skills, ~/.claude/agents, and local Claude Code session history
• No authentication or API keys required — the script reads local files only
