docs-publish — Push a local docs folder to GitHub

The actual work is done by the docs-publisher subagent (Haiku, pinned model).

Workflow#

1. Run gh auth status as the first step. If it fails, return manual instructions and exit — do not attempt to recover.
2. Derive the repo name from the folder name (which upstream skills set from the site brand or source repo — not a guess). If the folder name looks placeholder-ish or generic (e.g. docs-output, untitled, a timestamp), ask the user for a real name instead of publishing under it. Also ask if there is a genuine collision with an existing repo on their account.
3. If the folder is not already a git repo, run git init and make an initial commit. If .git already exists, skip init and reuse the current branch.
4. Create a new public GitHub repo without --source. Add the remote manually, then push main.
5. Use HTTPS with the gh auth token for the push, not SSH.
6. Report the GitHub URL, computed Docsbook URL, file count, and any warnings.

Guardrails#

• Never overwrite an existing repo — if the name is taken, bail with a clear error.
• Never push over SSH as a fallback; HTTPS with the gh token is the only supported transport.
• If gh is not installed, return the equivalent manual git and gh commands rather than failing silently.
• Keep _branding.json in the repo — it is consumed by downstream workspace configuration.

Acceptance Criteria#

• gh auth status verified before any git operation
• Repo name derived automatically; user only prompted on collision
• Repo created as public with no force-push
• Push completed over HTTPS using the gh token
• GitHub URL and Docsbook URL reported in the result
