About
Spences10 Claude Code Toolkit is a compact Claude Code plugin bundle for developers who treat agent setup as part of the product, not an afterthought. Eight plugins center on self-improving skills, performance visibility, and MCP essentials so you can stand up reliable tool access, measure session cost, and refine skills without forked one-off scripts. Typical use is mid-build when you are debugging agent behavior, authoring new SKILL.md files, or enforcing test-driven loops while multiple branches run in worktrees. The toolkit names explicit practices—red-green-refactor, secret redaction, omnisearch, sqlite tooling—so you pick plugins that match how you already ship with Claude Code. It is narrower than giant marketplaces but deeper on meta-work: how the agent remembers, recalls context, parallelizes tasks, and loads MCP servers safely. Install the marketplace, enable skill-creator and mcp-essentials first, then add analytics or team-mode plugins when collaboration or tuning becomes the bottleneck.
- 8 plugins in one toolkit focused on self-improving skills and MCP essentials
- skill-creator and evaluation patterns for iterating agent capabilities
- MCP tooling including mcp-essentials and selection helpers (mcpick)
- Session analytics, token usage, reflection, and team-mode orchestration hooks
- TDD and red-green-refactor workflows with worktree and tmux-friendly dev flows
