BC headspin-migration-skill

Migrate test automation from HeadSpin to TestMu AI (formerly LambdaTest) in any language or framework. Covers HeadSpin per-device Appium and Selenium endpoints (token in URL), headspin: capabilities, User Flows, the automation-config API, hs connect browser for Playwright and Puppeteer. Use this whenever someone wants to move, switch, port, migrate or point tests from HeadSpin to TestMu AI or LambdaTest, asks what the TestMu or LT:Options equivalent is for a capability, config, CLI flag or API from HeadSpin, mentions headspin.io, /v0/TOKEN/wd/hub, headspin:capture, headspin:testName, headspin:selector, headspin:quitSession, automation-config, hs connect browser, or wants a migration plan, estimate, PR or checklist for a repo currently on HeadSpin, even without the word migrate.

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.

Will not run. References files that are not bundled: ../shared/testmu-cloud-reference.md
  • 0Tools and files. 1 referenced file(s) missing: ../shared/testmu-cloud-reference.md
  • 0Inputs and preconditions. Does not say what the process needs to start
  • 60Result and completion. Output format stated, no completion criterion
  • 70When it triggers. States when to use, but not when not to
  • 70Execution cost. Instruction body is 4464 tokens
  • 85Steps. 45 steps, 1 vague phrases
  • 100Failures and branches. 2 branches, has a failure section
  • 100Consistency. Name and required fields are in place
  • 100Running it twice. Mutating operations check current state
  • 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.
