The Complete Claude Code Toolkit
Production-ready slash commands, subagents, hooks, MCP integrations, and CLAUDE.md templates โ every one tested, documented, and updated within 48 hours of every Anthropic release.
195 slash commands ยท 113 subagents ยท 52 hooks ยท 108 MCP guides ยท 52 templates
Not another AI blog. The reference library developers bookmark.
AI Code Toolkit exists because Claude Code changes every month, and every Google result for "claude code hook for X" or "claude code MCP for Y" is either outdated, incomplete, or someone's abandoned side project. We fix that. Every page here is production-tested by our editorial team and refreshed within 48 hours of every Anthropic release.
What we build
A definitive, searchable reference for every Claude Code primitive โ slash commands,
subagents, hooks, MCP integrations, CLAUDE.md templates โ plus a paid CLI toolkit
(cctk) that installs any of them into your project in seconds.
Who we build for
Working developers shipping real products with Claude Code โ indie hackers, SaaS founders, platform engineers, and enterprise dev leads. If you use Claude Code daily and want tested configs instead of hallucinated snippets, you're the audience.
Why it works
Claude Code changes fast โ no LLM summary can replace tested, current configs from a trusted source. Our editorial process, community submissions pipeline, and freshness discipline compound. Copy any snippet, ship in production, move on.
Five pillars. 520+ pages. Every Claude Code primitive covered.

Claude Code Weekly #13 โ Custom Skills Ship, MCP OAuth Gets Easier, and the 5 Hooks Every Team Is Using
The biggest release week of the quarter. Anthropic shipped Custom Skills into stable, MCP OAuth setup got a major UX overhaul, and we cover the 5 hooks every mid-size team is rolling out first. Plus: three community submissions we're merging into the library this week, a case study from a Y Combinator W26 team that cut their code review time 68%, and our take on where Claude Code fits in the emerging landscape of agentic coding tools.
Custom Skills โ When to Reach for This Over a Subagent
Anthropic's new Custom Skills feature overlaps subagents and slash commands. Here's the decision tree.

The exact 8 commands, 3 hooks, and 2 subagents they use โ and their monthly cost.
The Real Cost of Running Custom MCP Servers
We ran 5 popular MCP servers for 30 days. Here's what each actually costs โ with receipts.
Everything Anthropic Shipped for Claude Code in Q3 2026
Sixteen features, three deprecations, one pricing change. Our take on what matters.
One command to install every command, agent, and hook.
We're building cctk โ a CLI that installs any of the 520+ tested Claude Code
assets on this site directly into your project in seconds. No hunting through docs, no
copy-pasting between tabs. Just cctk install saas-starter and ship.
saas-starter, fastapi-prod, rails-monolith๐ We'll only email you about the cctk launch. No spam.
๐ก While cctk is being built, everything on the site is 100% free โ every command, agent, hook, MCP guide, template, tool, and guide. Start browsing the library โ
๐ Hit a Claude Code error?
Our sister site AI Error Hub has 120+ pages covering Anthropic API errors, Claude Code stack traces, MCP connection failures, and every "why is this broken?" moment. Cross-referenced with the snippets on this site.
FAQ โ Everything about AI Code Toolkit
Can't find your answer? Get in touch โ we usually reply within 24 hours.
AI Code Toolkit is the definitive reference library and CLI toolkit for Claude Code. It contains 195 slash commands, 113 subagent configs, 52 hooks, 108 MCP integration guides, and 52 CLAUDE.md project templates โ all production-tested by working developers. The paid Claude Code Toolkit CLI (cctk) installs everything into your Claude Code environment with one command.
Yes. All 520+ reference pages, 30 pillar guides, and 15 interactive tools are 100% free to use forever. A paid Toolkit CLI (cctk) is coming later โ it'll install all pre-built commands, agents, hooks, and templates automatically as a time-saving shortcut. Join the waitlist to be notified when it launches.
Working developers building with Claude Code โ indie hackers, SaaS founders, platform engineers, and enterprise dev leads. If you use Claude Code daily and want production-ready, tested configurations instead of building them from scratch, this is your reference. Junior devs also use us as a learning resource since every page shows working code with explanations.
cctk is our upcoming command-line tool. It'll install pre-built Claude Code assets directly into your project โ run cctk install saas-starter and get 40 commands, 15 agents, 8 hooks, Postgres MCP, Stripe MCP, and a CLAUDE.md ready in about 30 seconds. Right now we're focused on shipping the free content library first. Join the waitlist for launch updates and early-access pricing.
Anthropic's docs describe how Claude Code works. AI Code Toolkit gives you the actual code โ production-tested commands, hooks, agents, and MCP configs organized by real developer use cases, not by API surface. Plus the CLI product installs them for you. It's built for search intent ("claude code hook to prevent git push to main") not reference navigation.
In the first 90 days we focus exclusively on Claude Code to build depth โ no half-baked coverage of every tool. After Month 3 we expand to ChatGPT/Codex, Gemini, Perplexity, DeepSeek, Cursor, Copilot, Aider, Cline, and other AI coding tools. Our 40+ comparison pages already cover Claude Code against every serious competitor.
Yes. Every slash command, hook, subagent config, and MCP guide is tested by our editorial team before publishing. Each page shows a "Last tested" date and gets refreshed within 48 hours of every Anthropic Claude Code release. Our editor's job is literally to break code that doesn't work โ pages don't ship until they pass.
Yes. From Month 3 we open a community submissions GitHub repo. Approved contributors get bylines on their pages and rev-share on the marketplace launching in Q4 2026 (70/30 split). Weekly digest features the best community submission of the week.
Enterprise offerings โ SSO integration, on-prem library sync, audit logs, role-based access, and custom command development โ will launch alongside cctk. If you're planning an enterprise Claude Code rollout right now, get in touch and we'll work with you directly on consulting and a custom playbook. Contact us โ
Every Tuesday we ship a weekly digest โ new commands, agent configs, MCP integrations, and community submissions. Anthropic release-day updates ship within 48 hours. All 520+ pages are refreshed on a rolling 90-day freshness cycle. The freshness discipline is our biggest advantage over LLM summaries and abandoned side projects.
