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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.02210 | $0.02210 |
| Opus 5 | $0.01105 | $0.01105 |
| Sonnet 5 | $0.00442 | $0.00442 |
| Haiku 4.5 | $0.00221 | $0.00221 |
Grade A, and why
mediagateway CLAUDE.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 5d 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.

CLAUDE.md
This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
Project Overview
MediaRouter is an open-source unified API gateway for AI video generation providers (OpenAI Sora, Runway, Kling AI). It provides an OpenAI-compatible API with BYOK (Bring Your Own Keys) model, built with FastAPI backend and React frontend.
Development Commands
Quick Start (Recommended - Uses Pre-built Images)
./setup.sh # Initial setup - pulls pre-built images automatically
docker compose up -d # Start all services
docker compose down # Stop all services
docker compose pull # Update to latest images
docker compose restart backend # Restart backend only
docker compose logs -f backend # View backend logs
Pre-built Docker images are automatically pulled from GitHub Container Registry (ghcr.io). No build time required!
Local Development (Building from Source)
For development when you need to modify code:
# Use local build compose file
docker compose -f docker-compose.local.yml up --build
# Or uncomment "build:" lines in docker-compose.yml and:
docker compose build
docker compose up -d
Local Development (Without Docker)
Backend:
cd backend
python -m venv venv
source venv/bin/activate # Windows: venv\Scripts\activate
pip install -r requirements.txt
python run.py # Runs on http://localhost:3001
Frontend:
cd frontend
npm install
npm run dev # Runs on http://localhost:5173 or :3000
Backend with hot reload:
cd backend
uvicorn src.main:app --reload --port 3001
Testing
# Backend tests
cd backend
pytest
# Frontend linting
cd frontend
npm run lint
# Frontend build
npm run build
Architecture Overview
Provider System
Adding a new video provider:
- Create new file in
backend/src/providers/newprovider.py - Inherit from
VideoProviderbase class (seebackend/src/providers/base.py) - Implement required methods:
namepropertymodelspropertyvalidate_key()- Validate API keygenerate_video()- Start video generationcheck_status()- Poll generation statusget_supported_features()- Declare provider capabilities
- Register in
backend/src/providers/__init__.py:- Add to
PROVIDERSdict - Add models to
MODEL_PROVIDER_MAP
- Add to
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.

mediagateway CLAUDE.md is an instructions file published in the GitHub repository samagra14/mediagateway (12 stars, last pushed 11mo ago), licensed MIT. It adds 2,210 tokens to every session, about $0.0111 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
