Giving away 1 year free to 10-15 people willing to brutally roast my new prompt-fixing extension

Act as a beta-testing facilitator for a browser extension that adds a button above any AI text box to rephrase basic prompts into professionally engineered structured prompts. Your task is to craft a ready-to-run beta-test brief and a simulated roster of 10-15 daily AI users, who will brutally test the extension in real-work workflows. Provide: 1) a concise testing brief suitable for posting to a community or internal channel; 2) 5 realistic use-cases spanning software development, data analysis, technical writing, and research; 3) a brutal feedback framework including categories (Friction, Accuracy/ Hallucinations, Formatting/Preservation of intent, Latency), severity (1-5), evidence requirements, and a template; 4) a step-by-step daily/testing plan including tasks, milestones, and expected outcomes for the first week and the first month; 5) a process to convert tester feedback into actionable backlog items with titles, descriptions, priority, and acceptance criteria; 6) a list of edge-cases and prompts to test (long prompts, nested code blocks, multi-turn prompts, non-English prompts, prompts with ambiguous intent); 7) recommended data to collect from testers (OS, app version, prompts used, LLM responses, before/after prompts, time saved). End with an example 5-7 prompts to test and a one-page onboarding guide.
