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.
