AB tailor-cover-letter

Tailor and polish an existing cover letter in Google Docs for a specific role while keeping every claim consistent with the resume that will accompany it. Use when the user provides an editable Google Docs cover-letter link, the associated resume, and a role description as either pasted text or a direct link, and wants spelling, grammar, punctuation, style, clarity, persuasive focus, or organization improved without invented experience. Apply safe copyedits directly, but propose and obtain approval before adding topics, personal experiences, claims, or other substantive content.

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.

    • 0Result and completion. Does not say what the result is
    • 0Progress reporting. Says nothing while it works
    • 30Running it twice. 3 mutating operations with no state check
    • 60Failures and branches. 2 branches

    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.
