pragma-stack AGENTS.md

A project guide for a full-stack application with a Python FastAPI backend and a Next.js frontend. It explains how to install, run, test, and understand the main parts of the project.

In plain words
What is it for?
Use it to start the application, run backend and frontend tests, generate an API client, open API documentation, or find the code for authentication, users, organizations, and administration.
Why use it?
It saves developers from guessing which tools, commands, URLs, and folders the project uses. It also provides important setup details, including a default administrator account that should be changed before production use.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

pragma-stack AGENTS.md 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.

Quick Start

# Backend (Python with uv)
cd backend
make install-dev              # Install dependencies
make test                     # Run tests
uv run uvicorn app.main:app --reload  # Start dev server

# Frontend (Node.js)
cd frontend
bun install                   # Install dependencies
bun run dev                   # Start dev server
bun run generate:api          # Generate API client from OpenAPI
bun run test:e2e              # Run E2E tests

Critical Implementation Notes

Authentication Flow

  • JWT-based: Access tokens (15 min) + refresh tokens (7 days)
  • OAuth/Social Login: Google and GitHub with PKCE support
  • Session tracking: Database-backed with device info, IP, user agent
  • Token refresh: Validates JTI in database, not just JWT signature
  • Authorization: FastAPI dependencies in api/dependencies/auth.py
    • get_current_user: Requires valid access token
    • get_current_active_user: Requires active account
    • get_optional_current_user: Accepts authenticated or anonymous
    • get_current_superuser: Requires superuser flag

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.
