Opinionated multi-agent skill pack for Claude Code, Codex, and Cursor: deep skills for Stripe, Supabase, Plaid, Expo, copywriting frameworks, and agent meta-tooling, plus a TOON command wrapper for input-token savings.

Package Exports

  • create-agent-starter
  • create-agent-starter/src/index.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (create-agent-starter) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

agent-starter

An opinionated multi-agent skill pack for Claude Code, Codex, and Cursor. Deep, handwritten skills for fintech, SaaS, mobile, copywriting, agent tooling, code cleanup, and TOON token savings.

No orchestration framework. No aspirational YAML. Just agent-native project files generated from one shared skill source.

npm version License: MIT

Agent Targets

Agent Generated output Notes
Claude Code .claude/ Native Claude skills, settings, TOON slash commands, optional hooks.
Codex AGENTS.md + .codex/skills/*/SKILL.md Root Codex guidance points to project-local skill files.
Cursor .cursor/rules/*.mdc Cursor project rules generated as Agent Requested rules, plus an always-applied skill-selection rule.

Claude remains the default for backwards compatibility. Use --agent all to install all supported targets.

Install

# Claude Code only (default)
npx create-agent-starter@3.0.1

# Codex only
npx create-agent-starter@3.0.1 --agent codex

# Cursor only
npx create-agent-starter@3.0.1 --agent cursor

# Claude Code + Codex + Cursor
npx create-agent-starter@3.0.1 --agent all

# Backwards-compatible aliases still work
npx create-claude-starter@3.0.1 --agent all

For Claude TOON commands, add the runtime deps to your project:

npm i @toon-format/toon gpt-tokenizer

Profiles

npx create-agent-starter@3.0.1 --profile web-saas --agent all
npx create-agent-starter@3.0.1 --profile fintech --agent codex,cursor
npx create-agent-starter@3.0.1 --skills stripe,copywriting-frameworks --agent cursor

Profiles select a skill set. Agent targets decide where that skill set is installed.

Structure

.claude/
  skills/<skill>/skill.md
  commands/
  utils/toon/cli.mjs

.codex/
  skills/<skill>/SKILL.md
AGENTS.md

.cursor/
  rules/agent-starter.mdc
  rules/<skill>.mdc
  rules/<skill>/references/

The package keeps one shared source of truth in templates/.claude/skills/ and generates Codex/Cursor formats from that source during install.

Documentation Pulls

The docs command is Claude-specific because external docs are stored under .claude/skills/*/docs.

npx create-agent-starter@3.0.1 docs pull stripe
npx create-agent-starter@3.0.1 docs status

Benchmarks

Real measured token counts for representative workloads are in bench/. Numbers use gpt-tokenizer, not a claimed heuristic.

Requirements

  • Node.js >= 18
  • Claude Code, Codex, or Cursor, depending on the selected target
  • Optional: @toon-format/toon and gpt-tokenizer for Claude TOON slash commands
