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.
curl -fsSL https://raw.githubusercontent.com/majiayu000/spellbook/main/install.sh | bash -s -- --target all# Clone the repository
git clone https://github.com/majiayu000/spellbook.git
cd spellbook
# Install specific skills for Claude Code and Codex
./install.sh --target all --skills typescript-project,python-project,devops-excellence
# Or install everything for one runtime
./install.sh --target claude --all
./install.sh --target codex --all- Claude Code: type
/to see your installed skills. - Codex: restart Codex so it reloads
~/.agents/skills.
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.
Start with a small bundle that matches the job, then add more skills when the workflow sticks.

See Showcase for copy-paste prompts and expected outputs. Release history lives in Changelog.
- 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.
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.

Spellbook is in pre-1.0 release-readiness mode. No numbered GitHub release tag
has been cut yet; the current install path uses the repository main branch.
See Changelog for release history.
Current limitations:
- Codex installs skills only; Claude Code agents are skipped for Codex targets.
- Some skills depend on external CLIs, accounts, credentials, or platform access that are not bundled by the installer.
- The registry validator checks installable skill structure, not every external workflow end to end.
Support paths:
- Bugs: open an issue
- Feature ideas: open a feature request
- Security vulnerabilities: follow Security Policy
Built on the shoulders of giants:
- anthropics/skills - Official Anthropic skills
- obra/superpowers - Development methodology
- claude-code-plugins-plus - Plugin hub
- VoltAgent/awesome-claude-code-subagents - Agent collection

This project is one layer of an open-source stack for running coding agents (Claude Code, Codex) as serious infrastructure. Every piece works standalone; together they close the loop:
spellbook sits in the Extend layer — the authoring side of the skill story: write once, run on Claude Code and Codex. Discovery and distribution live in claude-skill-registry.
| Layer | Project | What it does |
|---|---|---|
| Extend | claude-skill-registry | Discover and search community Claude Code skills |
| Extend | spellbook ◀ you are here | Cross-runtime skills for Claude Code, Codex, and multi-agent workflows |
| Trust | argus | Static install-time scanner for supply-chain attacks (npm / PyPI / crates.io) |
| Trust | vibeguard | Rules, hooks, and guards against hallucinated or unverified agent changes |
| Remember | remem | Local-first persistent memory for Claude Code and Codex sessions |
| Orchestrate | harness | Rust agent orchestration platform — rules, skills, GC, observability |
| Route | litellm-rs | High-performance Rust AI gateway — 100+ LLM APIs via OpenAI format |
| Keep | keepline | Session command center — monitor, recover, never lose agent work |
