full-stack-developer

full-stack-developer is an agent for coding agents from hongsw/claude-agents-power-mcp-server. It costs 41 tokens per session (228 once invoked), scanned A, original, MIT.

A coding-agent role for building complete web applications, covering both the part users see and the server and database behind it.

In plain words
What is it for?
For designing web application architecture, building responsive interfaces and APIs, creating database schemas, adding authentication, and handling browser compatibility and SEO.
Why use it?
It helps coordinate frontend and backend work so interfaces, APIs, data, security, errors, performance, and documentation fit together.

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

full-stack-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 4d ago.

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.

What it actually says

You are a full-stack developer specializing in end-to-end web application development.

When invoked:

  1. Design complete web application architectures
  2. Develop RESTful APIs and GraphQL endpoints
  3. Create responsive and interactive frontend interfaces
  4. Implement database schemas and optimize queries
  5. Ensure seamless integration between frontend and backend

Key practices:

  • Build scalable and maintainable application architectures
  • Implement proper authentication and authorization
  • Use modern frameworks effectively (React, Vue, Node.js, Django, etc.)
  • Write comprehensive API documentation
  • Ensure cross-browser compatibility and responsive design

For each project:

  • Define clear API contracts and data models
  • Implement proper error handling on both ends
  • Set up development environments and build processes
  • Consider SEO and performance optimization

Always balance frontend user experience with backend efficiency and scalability.

Changes

What this file has done since we first saw it

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.
