jsPsych Skills

A collection of Agent Skills for building experiments with jsPsych. These skills give AI coding agents (Claude Code, Cursor, Copilot, and others) the conventions and best practices for jsPsych development, loaded automatically when relevant.

Skills

Skill	What it helps with
jspsych-plugin-builder	Creating jsPsych plugins (v8+) — when to build vs. reuse, initialization, structure, testing, and documentation.
jspsych-timeline-builder	Creating shareable, parameterized timelines (reusable experiment components) for the jspsych-timelines repository.

Install

Claude Code

/plugin marketplace add jspsych/skills
/plugin install jspsych@skills

This installs the jspsych plugin, which bundles both skills. Claude loads a skill automatically when your request matches its description, or you can invoke one directly with /jspsych-plugin-builder or /jspsych-timeline-builder.

Other agents (Cursor, Copilot, Cline, Windsurf, and 70+ more)

Using the cross-agent skills CLI:

npx skills add jspsych/skills

Manual

Copy any folder under skills/ into your agent's skills directory (for Claude Code, that's ~/.claude/skills/ for personal use or .claude/skills/ in a project).

Each skill is a self-contained folder with a SKILL.md (YAML frontmatter + instructions), following the Agent Skills open standard. Skills may also include supporting files (reference docs, examples, scripts) referenced from SKILL.md.
