Self-improving learning system that detects friction signals and proposes rule updates. This skill should be used when Claude needs to learn from mistakes, when users repeatedly correct behavior, when tool failures indicate missing knowledge, or when reviewing learning candidates via /coach commands.
/plugin marketplace add netresearch/claude-coach-plugin/plugin install coach@netresearch-claude-code-marketplaceThis skill inherits all available tools. When active, it can use any tool Claude has access to.
Coach enables Claude to learn from friction and improve over time. It detects learning opportunities (user corrections, repeated instructions, tool failures, tone escalation), extracts actionable improvement candidates, and proposes changes requiring explicit user approval.
Core Principle: No silent writes. All improvements require user approval via /coach approve.
Activate this skill when:
/coach commands| Type | Description | Example |
|---|---|---|
rule | Stable constraint | "Never edit generated files" |
checklist | Workflow step | "Run tests after code change" |
snippet | Repeatable command | "Preflight check script" |
skill | Skill update suggestion | "Add X guidance to Y skill" |
antipattern | Things to never do | "Never assume tool exists" |

Creating algorithmic art using p5.js with seeded randomness and interactive parameter exploration. Use this when users request creating art using code, generative art, algorithmic art, flow fields, or particle systems. Create original algorithmic art rather than copying existing artists' work to avoid copyright violations.
Applies Anthropic's official brand colors and typography to any sort of artifact that may benefit from having Anthropic's look-and-feel. Use it when brand colors or style guidelines, visual formatting, or company design standards apply.
Create beautiful visual art in .png and .pdf documents using design philosophy. You should use this skill when the user asks to create a poster, piece of art, design, or other static piece. Create original visual designs, never copying existing artists' work to avoid copyright violations.
