Use Nextbrowser cloud API to spin up cloud browsers for Openclaw to run autonomous browser tasks. Primary use is creating browser sessions with profiles (persisted logins/cookies) that Openclaw can control to manage social media and other online accounts. Secondary use is running task subagents for fast autonomous browser automation under residential proxy, browser stealth, and CAPTCHA solving capability. Docs at docs.nextbrowser.com.

How to improve

  1. The text references files that are not there: add them or drop the references.
For the model run — optional
  • Your own cases (evals/evals.json, 4–6 real requests with expected answers): the full check would then run those instead of a model-drafted suite.
  • A spec.yaml with trigger phrases and assertions — a behaviour contract for CI; `skilltest init` writes a template.

Process rating: all ten parameters 43/100

Will not run. References files that are not bundled: references/api.md
  • 0Tools and files. 1 referenced file(s) missing: references/api.md
  • 0Inputs and preconditions. Does not say what the process needs to start
  • 0Failures and branches. Linear process with no failure handling
  • 20When it triggers. No condition that starts the skill
  • 30Running it twice. 1 mutating operations with no state check
  • 60Result and completion. Output format stated, no completion criterion
  • 100Steps. 9 steps
  • 100Consistency. Name and required fields are in place
  • 100Execution cost. Instruction body is 1749 tokens
  • 100Progress reporting. Reports progress

Everything here is measured from the skill text rather than judged by a model, so the numbers are checkable. A parameter weighs more when it is a more common reason for the process to stall.
