I built a free Claude Code toolkit — 64 skills, 7 agents, 16 slash commands, and auto-formatting hooks for the full engineering stack
[Original Reddit post](https://www.reddit.com/r/ArtificialInteligence/comments/1tfz2b9/i_built_a_free_claude_code_toolkit_64_skills_7/)
Been using Claude Code daily and kept running into the same gap Claude knows the basics but misses the non-obvious patterns.
So I built claude-spellbook, a toolkit you install once and Claude just knows these things.
Repo:
https://github.com/kid-sid/claude-spellbook
Here's what's in it:
50 Skills, auto-activate when you're working on the relevant task
Every skill has a Red Flags section (7-10 anti-patterns with explanations) and a pre-ship checklist. The kind of stuff you only learn by breaking production.
7 Autonomous Agents
Subagents that run in their own context window with scoped tool access:
11 Slash Commands, prompt templates you invoke with / (e.g /mem_save)
Auto-formatting hooks — wired into settings.json
Every file Claude writes or edits gets auto-formatted instantly:
- .ts / .svelte → prettier + eslint --fix
- .py → black + ruff check --fix
- .go → gofmt + golangci-lint
- .rs → rustfmt + cargo clippy
- .md → markdownlint --fix
- skills/*/skill.md → custom format validator (checks frontmatter, ## When to Activate, ## Checklist)
Install:
# Skills
cp -r skills/* ~/.claude/skills/
# Agents
cp .claude/agents/* ~/.claude/agents/
# Slash commands
cp .claude/commands/* ~/.claude/commands/
Skills activate automatically. No manual invocation needed.
PRs welcome, especially skills for domains I haven't covered yet.

Share if you like it 😊 Let me know if there is something that should be fixed!
