Claude Code thinking skills 28 portable Agent Skills for structured reasoning in Claude Code, GitHub Copilot, Codex, Cursor, and other compatible tools Claude Code Thinking Skills is a public catalog of Agent Skills. Use it for decisions, diagnosis, systems, risk, strategy, and innovation. Each skill gives an agent a clear procedure. Use a skill when its mechanism fits the task. Jump to why use this catalog , quick start , use a skill , skill catalog , evidence , repository layout , checks and contribution , questions , or license . Use these skills when a problem needs a clear reasoning frame. The catalog covers diagnosis, decisions, creation, risk, execution, product, and strategy. Read the catalog audit before making performance claims. npx skills add tjboudreaux/cc-thinking-skills Install all skills without prompts: npx skills add tjboudreaux/cc-thinking-skills --all /plugin marketplace add tjboudreaux/cc-thinking-skills /plugin install thinking-skills@thinking-skills-marketplace git clone https://github.com/tjboudreaux/cc-thinking-skills.git mkdir -p /path/to/project/.agents/skills cp -R cc-thinking-skills/skills/ * /path/to/project/.agents/skills/ Claude Code can also load the same directories from ~/.claude/skills/ or .claude/skills/ . Start with the router when the right frame is unclear: Use thinking-model-router to choose the right framework for this problem. Invoke a leaf skill when the match is clear: Use thinking-scientific-method to localize this bug. Use thinking-reversibility to classify this architecture decision. Use thinking-pre-mortem to stress-test this launch plan. Use thinking-theory-of-constraints to find the binding bottleneck. The Claude Code plugin uses thinking-skills:thinking-model-router as the exact router ID. The router can return NONE , one skill, or up to three complementary skills. The 28 active skill IDs match the directories under skills/ Manage risk and execution The catalog audit reports: 28 active skills, all manual-only no automatic-retain verdict portfolio-v1 with zero model calls and an unmeasured result a provisional thinking-scientific-method row at +4.0 percentage points The +4.0-point row is below the +5-point utility margin and has evidence gaps. Treat it as directional evidence, not an accuracy claim.

External datasets follow their license limits. Validate skill structure: node scripts/validate-skills.js Run the local structural gate: EVAL_RUN=local node evals/run-structural.js Run routing evaluation with the authenticated droid CLI: EVAL_RUN=local node evals/run-routing.js Read the evaluation harness guide and CONTRIBUTING.md before changing the catalog. To add a skill, create skills/thinking-{name}/SKILL.md with Agent Skills YAML front matter, a precise trigger, a non-trigger boundary, a procedure, and checks. Run validation and the relevant evaluation before submitting. Which skill should I start with? Use thinking-model-router when the fit is unclear. Use a leaf skill when the task already names its mechanism. Can I use a skill without the router? Yes. Invoke any skill directly when its trigger matches. Do these skills guarantee better model accuracy? No. The evidence supports structured procedures, not a guaranteed accuracy gain. MIT License. See LICENSE for the full text.
