senior-fullstack

A full-stack development toolkit for creating projects with Next.js, FastAPI and React, MERN, or Django and React. It also reviews code quality, security, complexity, and technology choices.

In plain words
What is it for?
Use it to scaffold project boilerplate, select among supported stacks, and analyze code for quality or security issues.
Why use it?
It reduces the setup work for common web application stacks and gives structured guidance when choosing a stack or reviewing an existing codebase.

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

senior-fullstack 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 2d 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.

Origin

This is a copy

89% identical to senior-fullstack — 38 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

  • fastapi-react - FastAPI backend + React frontend + PostgreSQL
  • mern - MongoDB, Express, React, Node.js with TypeScript
  • django-react - Django REST Framework + React frontend

Usage:

# List available templates
python scripts/project_scaffolder.py --list-templates

# Create Next.js project
python scripts/project_scaffolder.py nextjs my-app

# Create FastAPI + React project
python scripts/project_scaffolder.py fastapi-react my-api

# Create MERN stack project
python scripts/project_scaffolder.py mern my-project

# Create Django + React project
python scripts/project_scaffolder.py django-react my-app

# Specify output directory
python scripts/project_scaffolder.py nextjs my-app --output ./projects

# JSON output
python scripts/project_scaffolder.py nextjs my-app --json

Parameters:

Parameter Description
template Template name (nextjs, fastapi-react, mern, django-react)
project_name Name for the new project directory
--output, -o Output directory (default: current directory)
--list-templates, -l List all available templates
--json Output in JSON format

Output includes:

  • Project structure with all necessary files
  • Package configurations (package.json, requirements.txt)
  • TypeScript configuration
  • Docker and docker-compose setup
  • Environment file templates
  • Next steps for running the project

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.
