Claude Code Skills Collection

A production-ready library of 262 skills and 75 orchestrating agents for Claude Code — covering thinking frameworks, research, writing, design, data/ML, corporate finance, game theory, fantasy baseball, an evolutionary 10-agent FIFA World Cup fantasy backroom, household personal finance, a 9-agent team for growing a Substack publication, and a 9-agent learning studio for becoming a contributor to ML-driven crop genetics / genomic selection. Also included: five reusable primitives for gated, verifiable research pipelines, and a 3-agent narrative team that turns researched evidence into structured long-form nonfiction.

Install in 30 seconds:

/plugin marketplace add lyndonkl/claude
/plugin install thinking-frameworks-skills

Note: Two skills need something installed separately: markdown-to-pdf needs pandoc and a LaTeX engine, and readability-check needs the textstat Python package. See Optional dependencies below. Every other skill works out of the box.

I want to…

Pick the fastest entry point for what you’re trying to do. Most users start with an agent (which orchestrates many skills); power users invoke skills directly.

Orchestrating Agents

Agents detect your need and route to the right skills. Each agent’s page documents the skills it orchestrates and the workflow it runs.

---

Optional native dependencies

A small number of skills wrap native command-line tools and only work if those tools are installed on the user’s machine. All such skills are optional. If a required tool is missing, the skill exits immediately with the exact install commands; nothing breaks silently and the rest of the library continues to work normally.

If you do not want to install the tools below, simply do not invoke the skills that need them. Every other skill in this repository, and every agent that does not include one of these skills in its pipeline, works without any additional native dependencies.

Skills with native dependencies

basictex on macOS is about 90 MB. Do not install mactex unless you specifically need the full LaTeX stack (~5 GB).

Agents that invoke these skills

Currently only one agent pipeline includes a dependency-requiring skill:

• product-strategist calls markdown-to-pdf in its final step to render the finished strategist report.

If you run product-strategist without pandoc or xelatex installed, the agent still produces its primary markdown report; only the PDF rendering step is affected, and the agent will surface the install instructions in that case. You can install the tools later and re-render any past markdown report on demand.

Installation

Option 1 — Plugin (recommended)

/plugin marketplace add lyndonkl/claude
/plugin install thinking-frameworks-skills

All 261 skills become available immediately. Claude invokes them automatically based on your request and each skill’s trigger description.

---

Using Skills

Skills activate automatically when you use matching trigger phrases — no manual invocation needed.

"Help me decide between three options..."      → decision-matrix
"I need to run user interviews..."              → discovery-interviews-surveys
"Value this company for acquisition..."         → acquisition-analyst (agent)
"What should I stream at pitcher this week?"    → mlb-streaming-strategist (agent)
"My chicken keeps coming out dry..."            → chef-assistant

---

Contributing

Fork, branch, and PR. Follow the skill structure above — SKILL.md under 300 lines, self-assess against the rubric (target ≥ 3.5), and include trigger phrases in the YAML description so Claude can auto-invoke.
