Workflow

This is the recommended end-to-end flow — from a blank project to a committed feature:

1. Install the plugin

/plugin marketplace add jgamaraalv/ts-dev-kit
/plugin install ts-dev-kit@ts-dev-kit

Run once after installing to align agents and skills with your actual stack, package names, paths, and MCPs:

/codebase-adapter

The skill reads your package.json, lockfile, .claude/agents/, and MCP config, then surgically patches the plugin's agent and skill files to match your project — without touching any workflow logic.

3. Define what to build

Generate a PRD from a description:

/generate-prd Add a user notification system that sends emails and in-app alerts

Then break it into agent-ready task files:

/generate-task

This produces structured task files with acceptance criteria, affected packages, quality gate commands, and a suggested agent.

4. Execute the task

/execute-task tasks/notifications-api.md

The skill picks the right execution mode (single-agent or multi-agent), dispatches the appropriate agents, and runs quality gates (typecheck, lint, test) before declaring the task done.

5. Commit

/conventional-commits

The skill pre-injects your staged diff and the last 8 commits so Claude sees the actual changes before suggesting a message — no copy-pasting needed.


Installation

Method 1: Claude Code Plugin (agents + skills)

/plugin marketplace add jgamaraalv/ts-dev-kit
/plugin install ts-dev-kit@ts-dev-kit

Or via CLI:

claude plugin install ts-dev-kit --scope user

Method 2: skills.sh (skills only — works with Claude Code, Cursor, Windsurf)

# Install all skills
npx skills add jgamaraalv/ts-dev-kit

# Install a specific skill
npx skills add jgamaraalv/ts-dev-kit --skill fastify-best-practices

# Install globally
npx skills add jgamaraalv/ts-dev-kit --global

Note: skills.sh installs skills only, not agents.

Method 3: npm

npm install -g @jgamaraalv/ts-dev-kit
claude --plugin-dir ./node_modules/@jgamaraalv/ts-dev-kit

Method 4: Direct from GitHub

git clone https://github.com/jgamaraalv/ts-dev-kit.git
claude --plugin-dir ./ts-dev-kit

Some agents and skills reference external MCP tools for documentation lookup, browser debugging, E2E testing, and web fetching. These are optional — skills degrade gracefully without them — but installing them unlocks the full experience.

MCP Server Used by Purpose
context7 Most skills (doc lookup) Query up-to-date library docs
playwright playwright-expert, debugger, test-generator Browser automation and E2E testing
chrome-devtools debugger Frontend debugging, screenshots
firecrawl execute-task Web fetching and scraping
sentry debugger, debug skill Error tracking and stack traces
posthog debugger User impact and error frequency

Installing as Claude Code plugins

claude plugin add context7
claude plugin add playwright
claude plugin add firecrawl

Installing as standalone MCP servers

# context7 — no API key required
claude mcp add context7 -- npx -y @upstash/context7-mcp@latest

# playwright — no API key required
claude mcp add playwright -- npx -y @playwright/mcp@latest

# firecrawl — requires FIRECRAWL_API_KEY
claude mcp add firecrawl --env FIRECRAWL_API_KEY=your-key -- npx -y firecrawl-mcp

chrome-devtools requires Chrome running with remote debugging enabled (--remote-debugging-port=9222). Refer to the Chrome DevTools MCP docs for setup instructions.


Dynamic Context Injection

Several skills use the !command`` syntax to pre-inject live data before Claude receives the prompt. This means Claude already has the real context when it starts — no manual copy-pasting required.

Skill What gets injected
/conventional-commits Staged diff summary, full staged diff, last 8 commit messages
/debug Last 10 git commits, working tree status
/codebase-adapter Working directory, lockfile, installed agents, MCP servers, package.json
/yolo Project root, devcontainer presence, Docker status, VS Code installation
