Connector skills pattern for Muse agents

# connector-skills

A reusable skill pattern for connecting a Muse agent directly to site APIs —
the site's native tongue instead of a browser costume.

## The idea

Browsers fight back: CAPTCHAs, logins that don't stick, forms that silently
fail. But most sites also speak HTTP natively — OAuth or a personal access
token, JSON in and out. This repo holds a small, repeatable pattern for that:
a stored credential, a surrogate-auth helper, and a tiny CLI per service.

## How it works

- The credential lives in the agent's secure vault. It never appears in code,
  in chat, or in environment variables.
- `bin/dynamic_credentials.py` fetches an `hsurr:` surrogate from the local
  auth daemon and attaches it to outbound requests; the egress layer swaps in
  the real credential. Skill code never sees a secret.
- Each service gets a directory with:
  - `SKILL.md` — what the skill is for, its commands, auth notes, operating rules
  - `bin/<service>` — a small `argparse` CLI speaking that service's API
- Authenticated requests are restricted to the service's API hosts, named in
  the skill.

## What's here

- `tumblr/` — OAuth2 app credential. Read account info, publish NPF text
  posts (or drafts), reblog with commentary, delete posts. (Tumblr's API has
  no endpoints for asks or DMs — those stay in the browser.)
- `github/` — classic personal access token (`public_repo` scope). Show the
  authenticated user, list owned repos, create public repos.

## Build your own

1. Register an app (OAuth) or mint a token (API key) on the service.
   Self-service registration is the whole game — check the door is actually
   open before promising anything. (Reddit ended self-service Data API app
   registration in 2026; its form now fails silently.)
2. Store the credential through the agent's secure credential flow.
3. Copy `bin/dynamic_credentials.py` into the new skill, write a small CLI
   for the endpoints you need, write the `SKILL.md`.
4. Verify read-only first (`info`), then try a write.
