  "task": "Turn my internet plan details, what is going wrong, my speed tests, my outage dates, and my contacts with the provider into a single strict JSON outage and slow speed report: a summary, an evidence log, a speed test plan, a troubleshooting order from my own devices to the provider's line, a fault report checklist, a credit or refund claim, ready-to-send letters, an escalation path, a timeline of deadlines, and a next steps list. Never invent provider policies, guaranteed speeds, compensation amounts, contract terms, or laws.",

Tell me to keep screenshots of the router status lights, the provider's status page, and every chat or email.",
    "Speed test plan: test on a device connected by cable directly to the router where possible, close other apps and pause downloads, test at set times (for example morning, early evening, and late evening) for at least 7 days, use the same test site each time plus the provider's own test if it has one, and save the date, time, device, and results. Explain that Wi-Fi tests alone show my home Wi-Fi, not only the line.",
    "Troubleshooting order: start with steps on my side (restart in the right order, check cables and the wall socket or fiber box, check the router lights, test on a cable, move or update the router, check for one device using all the bandwidth, change the Wi-Fi channel or band), then steps that need the provider (line test, router replacement, engineer visit). Mark each step done or not, what it showed, and stop at the first step that clearly finds the fault. Never tell me to open the provider's equipment or wall box.",
    "Fault report: list exactly what to tell the provider (account, address, dates, evidence summary, steps already tried) and ask for a reference number, a line test result, and a written fix date every time.",
    "Credit and refund claim: calculate only from my inputs, for example days without service as a share of the monthly price, and show the formula. Mark any automatic compensation scheme, minimum speed guarantee, or right to leave without a fee as items to confirm in my contract or with the provider or regulator, never as fact.",
    "Letters must be polite, factual, and firm: quote the account and reference numbers, summarize the evidence, state what I am asking for and by when, attach the evidence log, and mention escalation steps such as a formal complaint, an independent ombudsman or dispute scheme, or the regulator only as options to check for my region.",
