Agent Skills Marketplace

Personal collection of Agent Skills - a unified agentic development system that works across Claude Code, Cursor, VS Code Copilot, OpenAI Codex, and 20+ other AI tools.

Repository: https://github.com/thesimpleapp/agent-skills


Quick Install (Fresh Machine)

Install the complete Universal Cursor Bundle (agents, rules, skills, templates):

# Clone the repo
git clone https://github.com/thesimpleapp/agent-skills ~/.cursor/skills/agent-skills

# Run the installer (standard install - merges with existing config)
~/.cursor/skills/agent-skills/scripts/install-cursor.sh

# OR: Clean install (backs up and removes old config first)
~/.cursor/skills/agent-skills/scripts/install-cursor.sh --clean

Installer Options

Option Description
--clean Clean install: backup & remove existing agents, rules, skills, templates
--no-backup Skip backup (use with --clean for nuclear option)
--no-claude Skip Claude Code symlink setup
-v, --verbose Show detailed output

What Gets Installed

~/.cursor/
├── agents/           # 8 subagents (verifier, debugger, planner, etc.)
├── rules/            # 3 universal rules (coding-standards, agentic-workflow, openmemory)
├── templates/        # Project .cursor/ template
├── skills/
│   ├── agent-skills/ # This repository (40+ skills)
│   └── specialized/  # Specialized skills (d3js, etc.)

~/.claude/            # Claude Code compatibility
├── agents → ~/.cursor/agents (symlink)
└── skills → ~/.cursor/skills (symlink)

Project Setup

Configure agent-skills in any project:

# Setup in any project
cd your-project && ~/.cursor/skills/agent-skills/scripts/setup.sh .

# Windows PowerShell
~/.cursor/skills/agent-skills/scripts/setup.ps1 -ProjectDir .

This links skills, creates configs (with claude-flow MCP), and sets up Cursor compatibility.


Uninstall

To remove the Universal Cursor Bundle:

~/.cursor/skills/agent-skills/scripts/uninstall-cursor.sh

This removes agents, rules, templates, and specialized skills. The agent-skills repository itself is preserved.


Power User Setup (Claude Code Max)

For maximum capability with Claude Code CLI:

# Clone the repo
git clone https://github.com/thesimpleapp/agent-skills ~/.claude/skills/agent-skills

# Copy power mode config to your project
cp -r ~/.claude/skills/agent-skills/claude-code/* your-project/

This gives you:

  • Auto Model Selection: Opus for planning, Sonnet for code, Haiku for simple tasks
  • Parallel Agent Swarm: Up to 10 concurrent agents (64-core optimized)
  • Full Access Mode: Browser, filesystem, desktop, 500+ Rube integrations
  • Ultimate Onboard: Drop into any project and fully analyze/cleanup/document

Installation

Option 1: Just Paste the URL

Most AI coding tools can auto-detect and use skills from a GitHub URL:

https://github.com/thesimpleapp/agent-skills

Paste this URL into your AI coding assistant and ask it to install/use the skills.

Option 2: Claude Code (CLI)

# Clone to your skills directory
git clone https://github.com/thesimpleapp/agent-skills ~/.claude/skills/agent-skills

# Or register as a marketplace (if supported)
/plugin marketplace add thesimpleapp/agent-skills

Option 3: Cursor

# Clone to Cursor's skills folder
git clone https://github.com/thesimpleapp/agent-skills ~/.cursor/skills/agent-skills

Option 4: VS Code / GitHub Copilot

# Clone to your preferred location
git clone https://github.com/thesimpleapp/agent-skills ~/.vscode/skills/agent-skills

Option 5: Any CLI Tool

# Clone anywhere and point your tool to it
git clone https://github.com/thesimpleapp/agent-skills ~/agent-skills

# The skills are in the /skills folder
ls ~/agent-skills/skills/

Verify Installation

After installing, test by asking your AI assistant:

"Use the sprint-planning skill to plan my next feature"

The Unified Workflow

PROJECT INIT → CODEBASE ANALYSIS → SPRINT PLANNING → IMPLEMENT → SHIP
     ↓               ↓                    ↓              ↓
  CLAUDE.md     Architecture       Task Breakdown    Parallel
  Standards     Documentation      Batched for       Agents
                                   Agent Swarms

For New Projects

1. /project-init        → Establish standards and CLAUDE.md
2. /sprint-planning     → Plan first features
3. /flutter-excellence  → Build Flutter features
   /react-excellence    → Build React features
4. /supabase-mastery    → Optimize database

For Existing Projects

1. /project-init        → Assess current state
2. /codebase-analysis   → Deep dive analysis
3. /architecture-cleanup → Fix issues
4. /sprint-planning     → Plan improvements

For Complex Tasks

1. /context-loader      → Load project context
2. /orchestrator        → Analyze and spawn specialized agents
3. Parallel agents      → Execute batched tasks
4. /code-review         → Quality gate

After Client Meetings

1. Paste meeting URL (Fireflies, Fathom, Loom, etc.)
2. /meeting-to-tasks    → Smart detection:
   - Fireflies URL? → Try API first → Fallback to scrape
   - Fathom/Loom?   → Scrape public page
3. Generates MEETING_NOTES.md + SPRINT_TASKS.md
4. /sprint-planning     → Organize into batches

Parallel Agent Execution

These skills support parallel execution with multiple agents:

Task Batching

## Batch 1 (Parallel Safe)
Agent A: Feature module A
Agent B: Feature module B
Agent C: Feature module C

## Batch 2 (Sequential - depends on Batch 1)
Shared utilities update

## Batch 3 (Parallel Safe)
Agent A: Tests for A
Agent B: Tests for B
Agent C: Tests for C

Safe Parallelization Rules

  • ✓ Different features/modules
  • ✓ Independent components
  • ✗ Shared utilities (sequential)
  • ✗ Core architecture (sequential)

Templates

Starter templates for new projects:

Template Purpose
CLAUDE.md.template Project context file
business-logic.md.template Domain rules template
.mcp.json.template Portable MCP config
.env.template Environment variables

Using Templates

# Copy templates to new project
cp templates/CLAUDE.md.template my-project/CLAUDE.md
cp -r templates/.claude my-project/.claude
cp templates/.mcp.json.template my-project/.mcp.json
cp templates/.env.template my-project/.env.local

# Edit and replace {{VARIABLES}}

MCP Credential Portability

The .mcp.json.template uses environment variables for secrets:

{
  "mcpServers": {
    "supabase": {
      "env": {
        "SUPABASE_URL": "${SUPABASE_URL}",
        "SUPABASE_SERVICE_KEY": "${SUPABASE_SERVICE_KEY}"
      }
    }
  }
}

Config is portable (version controlled), secrets stay local (gitignored).


Rube Integration (Recommended)

Use Rube/Composio as the primary integration layer for 500+ apps.

Already Connected

  • Supabase - 12 projects, direct SQL access
  • GitHub - TheSimpleApp org, repos/issues/PRs
  • Notion - Simple. workspace

Available (One-Time OAuth)

RUBE_MANAGE_CONNECTIONS toolkit="vercel"     # Deployments
RUBE_MANAGE_CONNECTIONS toolkit="fireflies"  # Meeting transcripts
RUBE_MANAGE_CONNECTIONS toolkit="slack"      # Messaging
RUBE_MANAGE_CONNECTIONS toolkit="linear"     # Project management

Benefits Over Individual MCPs

  • One connection per service (not per project)
