OpenCode Zen - Check Free Models

Monitors the OpenCode Zen pricing page for new free models and offers to update your default configuration.

When this skill is triggered, follow this logic to keep the user's environment updated with the best available free models:

1. Fetch Pricing Page

Fetch the HTML content of the OpenCode Zen pricing documentation:

curl -sL [https://opencode.ai/docs/zen/#pricing](https://opencode.ai/docs/zen/#pricing)

2. Extract Free Models

Parse the webpage content (specifically looking at the pricing tables or lists) to identify available models. Extract the names/IDs of any models where the input/output cost is listed as "Free", $0.00, or models with names containing "free" (as well as known free stealth models like big-pickle).

3. State Comparison

Check the extracted list of free models against the state file located at ./zen_seen_models.json within the current workspace.

• If no changes are detected: Exit silently. Do not notify the user unless they manually invoked this skill.
• If a new free model is detected:
  1. Alert the user: "🚀 OpenCode Zen Update: I found a new free model on the pricing page: [Model ID]. It is now available."
  2. Ask: "Would you like me to set [Model ID] as your new default model for OpenClaw (for all Agents, Compaction, and Heartbeat)?"

4. Execution

• If the user confirms: Update the local OpenClaw configuration file in the workspace (e.g., config.yaml) or set the relevant environment variables to the new model ID.
• Finalize: Save the newly updated list of free models as a JSON array to ./zen_seen_models.json in the workspace to ensure the user is not prompted again for these specific models.
