portless-local skillF

portless-local is agent-read markdown (skill) from jellydn/my-ai-tools: Replace port numbers with stable named .localhost URLs for local development.

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

What the file says

# Portless - Named .localhost URLs

Replace port numbers with stable, named `.localhost` URLs for local development. For humans and agents.

> **Note:** By default, use HTTP (`http://myapp.localhost`). Only enable HTTPS (`--https` or `PORTLESS_HTTPS=1`) if the user specifically requests it (e.g., for OAuth, secure cookies, or HTTPS-only features).

## Why Portless?

Local dev with port numbers is fragile. Portless fixes that by giving each dev server a stable, named `.localhost` URL.

| Problem                    | With Ports                                              | With Portless                                   |
| -------------------------- | ------------------------------------------------------- | ----------------------------------------------- |
| **Port conflicts**         | Two projects on :3000 = EADDRINUSE                      | Auto-assigned ports, named URLs - no collisions |
| **Memorizing ports**       | "Was the API on 3001 or 8080?"                          | Always `http://api.localhost`                   |
| **Wrong app on refresh**   | Stop one server, start another on same port = confusion | Named URLs eliminate this                       |
