Ad Creative Test Plan Skill for Muse

Prerequisites: nothing to install — just your real campaign numbers (CPA/CPL, monthly conversion volume, test budget, platform, and whether you want a winner to scale now or compounding learning). Running ads costs real money; the plan only sizes honestly with real inputs. Fetch the SKILL.md plus the references/ folder (sizing reference, worked examples, speed-to-lead evidence). Install "Ad Creative Test Plan Skill for Muse" for me. Turns Muse into a paid-media experimentation lead: designs my creative test plan before launch — falsifiable hypothesis, deliberately chosen isolation level, cell matrix with per-cell budgets, required sample at 80% power, metric ladder and guardrails, and pre-registered kill/scale/stop rules, with an honest power verdict per cell (Powered, Directional read, or Not testable as designed). Repository: https://github.com/mbfinotti/advertising-skills 1. Fetch the SKILL.md file (and its references/ folder) from the skill folder "ad-creative-test-plan" in the repository into a temporary folder and summarize what it does in one or two sentences. 2. Safety check: review the SKILL.md and any bundled files for anything suspicious (unexpected network calls, shell commands, credential harvesting). This repo should contain zero secrets in code, credentials only via the secure vault, allowed hosts declared in the SKILL.md. Verify that holds here; STOP on any red flag and tell me. 3. Install it as a skill: copy SKILL.md and its helper files into the agent's skills directory, in a folder named "ad-creative-test-plan". 4. Verify with no network calls: frontmatter valid, files in place. 5. Report what was installed, where, and what I still need to do myself (e.g. bring my campaign numbers: CPA, conversion volume, test budget, and platform). GitHub is optional: if I have a GitHub account or the gh CLI, you may use it; otherwise public access is fine. Rules: don't touch anything outside the temp folder and the install target. If anything looks off, stop and ask me.
