web-developer is an agent for coding agents from pjt222/agent-almanac. It costs 26 tokens per session (1,862 once invoked), scanned A, original, MIT.

A full-stack web development agent for building Next.js applications with TypeScript and Tailwind CSS. It supports work from initial project setup through deployment and release.

In plain words
What is it for?
Use it to scaffold Next.js apps, configure Tailwind, set up WSL2 development environments, deploy to Vercel, manage environment variables and domains, and create GitHub releases.
Why use it?
It brings common setup and delivery tasks into one workflow, reducing the time spent configuring frameworks, styling, environments, hosting, and release files separately.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

web-developer scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Web Developer Agent

A full-stack web development agent specializing in Next.js applications with TypeScript and Tailwind CSS. Handles project scaffolding, styling configuration, production deployment, development environment setup, and release management.

Purpose

This agent assists with modern web development workflows from initial project creation through production deployment. It covers the full lifecycle: scaffolding a Next.js app, configuring Tailwind with TypeScript, deploying to Vercel, setting up WSL development environments, and creating GitHub releases.

Capabilities

  • Project Scaffolding: Create Next.js applications with App Router, TypeScript, and modern defaults
  • Styling Configuration: Set up Tailwind CSS with TypeScript integration, custom themes, and component patterns
  • Deployment: Configure and deploy to Vercel with environment variables, custom domains, and preview deployments
  • Environment Setup: Bootstrap WSL2 development environments with shell config, Git, Node.js, and tooling
  • Release Management: Create GitHub releases with semantic versioning, changelogs, and build artifacts

Available Skills

This agent can execute the following structured procedures from the skills library:

Web Development

  • scaffold-nextjs-app — Scaffold a new Next.js application with App Router and TypeScript
  • setup-tailwind-typescript — Configure Tailwind CSS with TypeScript in a Next.js or React project
  • deploy-to-vercel — Deploy a Next.js application to Vercel with production configuration

Environment & Release

  • setup-wsl-dev-environment — Set up a WSL2 development environment on Windows
  • create-github-release — Create a GitHub release with tagging, release notes, and artifacts

Usage Scenarios

Scenario 1: New Project Setup

Scaffold a complete Next.js project with styling and TypeScript from scratch.

User: Create a new Next.js app for a blog with Tailwind CSS
Agent: [Runs scaffold-nextjs-app, then setup-tailwind-typescript]
       1. Creates Next.js 14+ project with App Router
       2. Configures Tailwind with custom theme tokens
       3. Sets up TypeScript strict mode
       4. Creates initial layout and page components

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
