Add Claude Opus 4.7 support

## What changed OpenClaw added default support for Claude Opus 4.7 on 18 May 2026. Anthropic model selections now route to Opus 4.7 by default. CLI aliases and configuration files updated to point at the new model without extra flags.

The change improves output quality on reasoning tasks and long context work. Users who connect an Anthropic key see the switch automatically after the next update.

## Why it matters Better default models raise the floor for what a self-hosted agent can handle without constant prompt tweaks. Vibe Builders gain more reliable browser control and skill writing, yet they also face higher per-token costs from Opus usage.

The move pressures competing agents that still default to lighter models. It bets that users will accept the spend for fewer failed runs on complex jobs.

## How to use it Pull the latest OpenClaw release through the existing CLI command. Edit the YAML file to confirm anthropic.model equals opus-4-7 or leave it blank to accept the new default. Restart the agent and test a single scheduled task to verify the model switch.

Set a hard spend cap in the Anthropic console before running heavier sessions. Monitor the first week of token usage through the provider dashboard.

## Watch for Confirm the bet by measuring fewer task retries on form-filling and research jobs. Watch for monthly bills above $50 as the signal to add usage alerts or switch back to a lighter default. Expect a follow-up release that adds cost controls inside the YAML file itself.
