Editor-selected existing cases and prompts, separate from AI news. Selection dates use Hong Kong time.
Oct 31: 5 existing cases rechecked: unit prices, export reconciliation, learning hints, bookmark indexes and manual lookup. Supplied text; not new/tested or source integrations. Gemini web lists HK/MO/TW and TC/SC/English; eligibility/limits apply. TW Free NT$0; HK/MO paid prices and language quality unverified. App/API differ. No shopping, data edits, code execution or car control. Human review.
Compare supplied quotes while separating volume, count, member prices and bundle conditions; unknown fees are not zero.
Prompt
Using only [supplied quotes: sources, check times, specifications, pack volume/count, currency, prices and promotion terms], draft a comparison for [product/acceptable substitutes/required quantity/comparison unit/collection method]. Check comparability first, then show unit-price calculations and the total outlay actually required. Separate membership, bundles, deposits, delivery and taxes. Unknowns are not zero; do not mix currencies or invent exchange rates. Do not rank insufficiently specified offers or call old quotes current. Return a draft and verification questions only, without browsing, signing in, shopping or paying.
Evidence limits and cautions
A single report is not an independent price audit. Historical quotes are not live prices, and a lower unit price need not mean a lower required outlay.

Compare two de-identified text tables record by record, checking nulls, duplicate keys and field changes even when totals match.
Prompt
Compare [de-identified source and exported text tables: row IDs, fields and values] using [expected field mappings, types, date/timezone, multivalue and null rules]. Draft additions, omissions, duplicate IDs and changed values by ID. Flag ambiguous duplicates rather than matching them arbitrarily. Distinguish blank, null, zero and missing input; retain original dates without guessing timezones or truncating multivalues. Equal totals do not establish parity. Identify source rows for human checks. Process pasted text only, without reading files, calling APIs, changing records, connecting accounts or sharing.
Evidence limits and cautions
The source does not expose complete reproducible data; one successful transfer does not establish lossless exports generally.

Define what you want to learn and have AI wait for your attempt before giving partial hints and feedback.
Prompt
For [an authorized, ungraded exercise] and [my current knowledge/learning goals/parts I want to complete/language], act as a text tutor. First ask for my reasoning and wait. Then give partial hints or an incomplete scaffold at [my chosen hint depth], waiting for my attempt before each round of feedback. Identify specific reasoning gaps and ask me to explain with a new example. Working answers do not establish understanding. Mark absent tool results as unverified. Do not complete the entire exercise, submit coursework, write files, install or execute code.
Evidence limits and cautions
An author’s experience is not a learning-outcomes experiment. A completed answer does not establish understanding; this exercise is untested.

Draft an index from supplied excerpts, separating updates, possible duplicates and unresolved links.
Prompt
From [existing index and new records: IDs, public URLs, titles, dates, authorized short excerpts and read status], draft updates using [category preferences/version-retention rules/language]. Preserve original URLs and excerpt locations. Separate confirmed matches, possible duplicates and versions; similar titles do not establish the same page, and do not strip query parameters to assume equivalence. Mark unreadable or absent excerpts unknown rather than guessing. Explain proposed additions, merges and retained items without actually overwriting, deleting, opening links, creating files or syncing. Include no token-bearing URLs or private data.
Evidence limits and cautions
The author’s report does not establish long-term retrieval accuracy. A draft does not mean records were saved, synchronized or updated.

Use supplied manual excerpts with model, year, market and page references, without diagnosing or controlling a vehicle.
Prompt
I am safely parked. Using only [authorized short manual excerpts: model, year, sales market, version, page references and complete relevant warnings], help me understand [a non-urgent, non-safety-critical cabin-operation question/language]. Check version applicability first, then explain only supported steps and conditions, retaining warnings and gaps. Stop if uncertain; invent no pages or cross-model assumptions. Do not diagnose faults, recommend repairs, judge driving safety or infer sensor/live vehicle data. Refer warning-light, brake, tyre or other safety issues to the manufacturer or qualified personnel. Do not connect to the car, change settings or install hardware; return text for human checking only.
