What's inside
Skill(105 skills)
/idea-analogist想法群聊室 — 类比者角色。被 idea-team 主编排器调用，或用户单独说"类比一下"、"别的行业有没有"、"yes-and 扩展"、"X 让你想到什么"、"跨界启示"时触发。**专门做跨界类比 + yes-and 扩展——不评判、不挑刺、不要求事实证据**。Do NOT use when 用户要数据（用 `idea-research`）、要反方意见（用 `idea-devils-advocate`）、或要严谨论证（类比是启发，不是论证）。/idea-devils-advocate想法群聊室 — 反方角色。被 idea-team 主编排器调用，或用户单独说"反方意见"、"挑这个想法的刺"、"为什么会失败"、"找漏洞 / 反例"、"devil's advocate"时触发。**专门挑漏洞、找隐藏假设、给反例——不安慰、不"也许可以这样"、不全盘否定**。Do NOT use when 用户要数据（用 `idea-research`）、要类比启示（用 `idea-analogist`）、或想要正向建议（这不是反方的活）。/idea-research想法群聊室 — 调研员角色。被 idea-team 主编排器调用，或用户单独说"调研一下 X"、"X 的现状/竞品/数据"、"找 2026 数据"、"事实底"时触发。**用 WebSearch 拉真实 2026 数据、列竞品、引来源——只给事实，不评判，不建议**。Do NOT use when 用户要评价想法好坏（那是反方）、或要跨界启示（那是类比者）、或已有 PRD 在跑（不需要这种调研）。插件内 skill 会由 `idea-coach` namespace 路由；catalog 用户直接按 skill 名调用。

README
Rename notice: Spellbook was formerly Claude Arsenal. Claude Code remains a first-class target; the new name reflects the broader roadmap for Claude Code, Codex, and cross-runtime agent skills. See the migration note for details.
Quick Start
Start with one job-shaped workflow. The maintained skills CLI lets you choose
the supported coding agents during installation and installs only these four
skills:
npx skills add majiayu000/spellbook --skill frontend-design --skill app-ui-design --skill ui-design-system --skill figma-to-react
Use npx skills add majiayu000/spellbook --list to inspect the catalog before
installing. See Pick a Workflow for four other focused
starting points.
Advanced Cross-Runtime Installer
install.sh remains available when you want explicit Claude Code/Codex target
paths or need to install the repository's Claude Code agents as well as skills.
# Install all skills and supported agents into both maintained runtimes
curl -fsSL https://raw.githubusercontent.com/majiayu000/spellbook/main/install.sh | bash -s -- --target all
# Or clone the repository and select skills explicitly
git clone https://github.com/majiayu000/spellbook.git
cd spellbook
./install.sh --target all --skills typescript-project,python-project,devops-excellence
Verify Installation
- Claude Code: type
/to see your installed skills. - Codex: restart Codex so it reloads
~/.agents/skills.
Runtime Targets
Spellbook keeps the skill source in one place and installs it into the runtime you use.
| Target | Installed To | Status |
|---|---|---|
| Claude Code | ~/.claude/skills plus ~/.claude/agents | Skills and agents supported |
| Codex | ~/.agents/skills | Skills supported; agents skipped |
| All | Both Claude Code and Codex paths | Recommended for multi-tool users |
Claude Code remains a first-class target and search entry. The project was formerly known as Claude Arsenal; the new Spellbook name reflects the broader goal: reusable skills that can travel across coding agents.
Older Spellbook versions installed Codex skills under ~/.codex/skills; reinstall with the current installer to use the documented Codex user-level skill path.
Pick a Workflow
Start with a small bundle that matches the job, then add more skills when the workflow sticks.
| Workflow | Install | Good for |
|---|---|---|
| Frontend and UI | npx skills add majiayu000/spellbook --skill frontend-design --skill app-ui-design --skill ui-design-system --skill figma-to-react | Product UI, landing pages, design systems, Figma handoff |
| Code quality | npx skills add majiayu000/spellbook --skill codebase-audit --skill flowguard --skill systematic-debugging --skill review-gate | Audits, guarded delivery, root-cause debugging, pre-landing review |
| Ops and release | npx skills add majiayu000/spellbook --skill release-engineering --skill server-security --skill clash-doctor --skill system-doctor | Release planning, server hardening, and local or network diagnosis |
| Product and docs | npx skills add majiayu000/spellbook --skill product-discovery --skill prd-master --skill technical-spec --skill product-analytics | Discovery, PRDs, technical specs, metrics plans |
| Agent workflows | npx skills add majiayu000/spellbook --skill codex-agent --skill multi-ai-research --skill flowguard --skill vibeguard | Cross-review, multi-AI research, context handoff, anti-hallucination checks |
High-signal individual skills to try first: github-trending, harmonyos-app, app-ui-design, product-discovery, xiaohongshu, codebase-audit, and server-security.
See Showcase for copy-paste prompts and expected outputs. Use the Spellbook Skill Browser for curated first-party skills, or the Claude Skills Registry for broader community discovery. Release history lives in Changelog.
Why Spellbook
- Cross-runtime install: one source tree can install into Claude Code and Codex.
- Validated registry: every installable skill is checked by
python3 scripts/validate_skills.py --check. - Progressive disclosure: larger skills use
references/,templates/,scripts/, and eval files instead of one giant prompt. - Practical coverage: engineering, operations, product, UI, content, and agent workflows live in one catalog.
Skills
The generated full skill inventory lives in Skill Registry. Skill layout rules live in Skill Format Policy. Skill authoring quality rules live in Skill Quality Playbook.
Search the Registry
# Free-text query (AND semantics across name, description, category, tags)
python3 scripts/validate_skills.py search rust testing
# Filter by tag
python3 scripts/validate_skills.py search --tag agent
# Restrict to a description language
python3 scripts/validate_skills.py search --language zh deploy
# Machine-readable output
python3 scripts/validate_skills.py search --tag react --json
The tag index lives in registry/tags.json for tooling and dashboards. Curated overrides for skills the keyword heuristic cannot infer live in registry/tag_overrides.yml.
Audit non-blocking skill quality signals:
python3 scripts/audit_skill_quality.py
python3 scripts/audit_skill_quality.py skill-creator
