omp-zai-coding-plan

An Oh My Pi plugin that adds Z.AI GLM Coding Plan browser sign-in (OAuth).

Run /login, pick "Z.AI (GLM Coding Plan · Sign in)", finish the sign-in in your browser, and the plugin provisions a durable Z.ai id.secret API key for you. No key to paste. Ships a /glm-usage command to read your remaining plan quota.

The provider id is zai-coding-plan, independent from the paste-key zai provider, so both can be configured at once.

Models

Model	Context	Max output	Thinking
zai-coding-plan/glm-5.2	1,000,000	131,072	high, max
zai-coding-plan/glm-5-turbo	200,000	131,072	on (single tier)

How sign-in works

Mirrors the ZCode desktop "Individual Plan" browser flow:

1. Authorize — opens chat.z.ai (authorization code, no PKCE) and hosts a loopback callback server on port 54548.
2. Token exchange — trades the returned code for a short-lived OAuth access token.
3. Business login — exchanges that token for a durable biz token.
4. Key mint — resolves your default org/project, finds or creates an oh-my-pi-named API key, and reads its secret, yielding the durable apiKey.secretKey bearer.

If the browser can't reach this machine, paste the final redirect URL (or the code/state) when prompted.
