BC playground-snapshot-release

Publish a Playground UI snapshot (`@mastra/playground-ui` and its workspace dependencies) from `main` or the current branch via the `playground-snapshot` mode of the Publish to npm workflow, wait for it to finish, then open a PR on `mastra-ai/platform` bumping the frontend to the published snapshot version. Use when asked to release, publish, or ship a playground/studio UI snapshot to the platform frontend.

How to improve

    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 59/100

    • 0Result and completion. Does not say what the result is
    • 20When it triggers. No condition that starts the skill
    • 30Inputs and preconditions. Does not say what the process needs to start
    • 30Running it twice. 25 mutating operations with no state check
    • 60Tools and files. Uses tools (git) that frontmatter does not declare
    • 100Steps. 7 steps
    • 100Failures and branches. 1 branches, has a failure section
    • 100Consistency. Name and required fields are in place
    • 100Execution cost. Instruction body is 1612 tokens
    • 100Progress reporting. Reports progress
    • low The response is described with custom markup (4 tags): a typed call is more reliable

    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.

    • +5Description has no quoted example phrases that should trigger the skill
    • +4Description does not say when NOT to use the skill (false activations)
    • +3Output format is not stated: the model decides each time
    • +1No license
    • +2Single-language instructions
