OpenCode Zen - Check Free Models

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.
