Summary

gemini-3.1-pro-preview launched today (Feb 19, 2026) and is available via the Gemini CLI (gemini -m gemini-3.1-pro-preview), but the google-gemini-cli provider in OpenClaw rejects it with Unknown model: google-gemini-cli/gemini-3.1-pro-preview.

Steps to Reproduce

1. Set an agent model to google-gemini-cli/gemini-3.1-pro-preview
2. Send a message to that agent
3. Error: Unknown model: google-gemini-cli/gemini-3.1-pro-preview

Expected Behavior

The model should be recognized and routed to the Gemini CLI, same as gemini-3-pro-preview.

Environment

• OpenClaw: 2026.2.19-2
• OS: macOS (arm64)
• The standalone Gemini CLI works fine: gemini -m gemini-3.1-pro-preview "hello" responds successfully.

Notes

The model catalog appears hardcoded in the gateway binary. Adding the model via models.json (per-agent registry) or models.providers in openclaw.json did not resolve the issue — the provider-level validation rejects the ID before it reaches the CLI.
