SkillKit

Production observability for AI agent skills. Monitors usage, detects conflicts, analyzes cost, and prunes what you don't use.

Commands

SkillKit is a standalone CLI. Run with npx @crafter/skillkit <command> or install globally (npm i -g @crafter/skillkit ).

Usage & Budget

  • skillkit scan

  • Discover skills + index session data (auto-runs on first use)

  • skillkit stats

  • Usage analytics with sparklines (last 30 days)

  • skillkit stats --all --days 90

  • Full list over 90 days

  • skillkit list

  • Installed skills with size and context budget

  • skillkit health

  • Unused skills + metadata budget check

Cost Analysis

  • skillkit context

  • Context tax: tokens + cost of CLAUDE.md, skills, memory per API call

  • skillkit context --sonnet --turns 60

  • Custom model pricing and session length (default: opus)

  • skillkit burn

  • Daily burn rate, model breakdown, runway projection (40+ models priced)

  • skillkit burn --days 7

  • Custom range

  • skillkit burn --set-plan

  • Interactive plan selector (arrow keys)

  • skillkit burn --claude-plan 200 --cursor-plan 20

  • Per-agent plan flags

Quality & Conflicts

  • skillkit conflicts

  • Detect trigger collisions between skills

  • skillkit coverage <skill-path>

  • Find dead weight (unreferenced sections + files)

Cleanup

  • skillkit prune
  • List unused skills (add --yes to delete)

Trace (Internal)

  • skillkit trace <prompt>
  • Record skill execution trace (powers conflicts + coverage)

Filters

  • Any command with --claude , --cursor , --codex , --gemini , --windsurf , --amp , --goose , --kiro , --roo , or --opencode to filter by agent

When to Use

  • "which skills do I use the most?" -> skillkit stats

  • "are there unused skills?" -> skillkit health then skillkit prune

  • "what's my context tax?" -> skillkit context

  • "how much am I spending?" -> skillkit burn

  • "do any skills conflict?" -> skillkit conflicts

  • "is this skill bloated?" -> skillkit coverage <path>

  • "set my plan/budget" -> skillkit burn --set-plan

Decision Guide

  • First time? skillkit stats -- auto-discovers and indexes everything

  • Full picture? skillkit stats --all --days 90

  • Context tax? skillkit context

  • Cost check? skillkit burn

  • Conflicts? skillkit conflicts

  • Dead weight? skillkit coverage ~/.claude/skills/my-skill/

  • Cleanup? skillkit health then skillkit prune --yes

How It Works

Discovers skills across 12 agents: Claude Code, Cursor, Codex, Gemini CLI, Windsurf, Amp, Continue, Goose, Kiro, Roo Code, Antigravity, OpenCode. Session connectors parse JSONL/JSON traces for Claude, Cursor, Codex, Gemini, and OpenCode. Deduplicates skills by name and inode. All data local in ~/.skillkit/analytics.db . Plan config stored in ~/.skillkit/config.json .

find-skills

Helps users discover and install agent skills when they ask questions like "how do I do X", "find a skill for X", "is there a skill that can...", or express interest in extending capabilities. This skill should be used when the user is looking for functionality that might exist as an installable skill.

pptx

Use this skill any time a .pptx file is involved in any way — as input, output, or both. This includes: creating slide decks, pitch decks, or presentations; reading, parsing, or extracting text from any .pptx file (even if the extracted content will be used elsewhere, like in an email or summary); editing, modifying, or updating existing presentations; combining or splitting slide files; working with templates, layouts, speaker notes, or comments. Trigger whenever the user mentions "deck," "slides," "presentation," or references a .pptx filename, regardless of what they plan to do with the content afterward. If a .pptx file needs to be opened, created, or touched, use this skill.
