What is skillkit CLAUDE.md?

Repository instructions for Skillkit, a desktop application that manages reusable instructions, called skills, for AI coding tools. It is organized as a pnpm-workspace monorepo, meaning one repository contains multiple related packages managed together.

It helps maintain the Electron desktop client, shared TypeScript definitions, workspace commands, and integrations that install or share skills across coding tools.

It explains the desktop app, shared types, external server, and required commands, helping developers know where a change belongs and what must stay synchronized.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.02722	$0.02722
Opus 5.5	$0.01089	$0.01089
Sonnet 5.5	$0.00544	$0.00544
Haiku 4.5	$0.00272	$0.00272

Security

Grade B, and why

skillkit CLAUDE.md scanned grade B with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

CLAUDE.md

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

What this is

Skillkit — manage "skills" across AI coding tools (Claude Code, Codex, Cursor, Trae, Workbuddy): browse the skills.sh marketplace, install/uninstall from market/GitHub/zip, and share installed skills via short links. A pnpm-workspace monorepo with two parts:

apps/desktop — Electron desktop client (React 18 + TypeScript + Vite + better-sqlite3). This is what's open-sourced here.
packages/types — @skillkit/types: cross-process shared types & constants (single source of truth).

The server (share short-link API + web 个人中心, Next.js 16) used to live here as apps/server but has moved to a separate repo at ../skillkit.net (the product 官网 + backend). The desktop client talks to it over HTTPS at https://skillkit.net (share + auth endpoints; login = https://skillkit.net/login, no account. subdomain). packages/types is mirrored (vendored) into that repo so the wire contract stays in sync — when you change share/auth types or the tool list here, update the vendored copy in skillkit.net/lib/shared-types.ts too.

Commands

Run from the repo root.

pnpm install                 # workspace install (links @skillkit/types, installs apps/desktop deps)

# Desktop (apps/desktop)
pnpm --filter desktop run rebuild   # REQUIRED: rebuilds better-sqlite3 against Electron's ABI. Run after install / Electron bumps.
                                   # ⚠️ Must use `run rebuild` — `pnpm rebuild` is a pnpm built-in that reruns install scripts against the *system* Node ABI (→ NODE_MODULE_VERSION mismatch); only the `scripts.rebuild` entry (`electron-rebuild -f -w better-sqlite3`) compiles against Electron's headers.
pnpm --filter desktop dev       # Full Electron app in dev (vite-plugin-electron launches Electron + watches all 3 bundles)
pnpm --filter desktop build     # tsc -p both tsconfigs (typecheck, noEmit) + vite build
pnpm --filter desktop pack      # build + electron-builder --dir (unpacked, for debugging)
pnpm --filter desktop dist      # build + electron-builder → release/ (mac dmg/zip, win nsis)

# Repo-wide (turbo)
pnpm dev        # turbo dev — runs desktop dev
pnpm build      # turbo build
pnpm typecheck  # turbo typecheck

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
