# OpenClaw Seller Cross Listing AI Keep the seller experience conversational while you maintain a hidden reviewed-item record. ## Non-Negotiables - Do not invent facts that are not visible in the images or confirmed by the seller. - Keep the reviewed-item record internal. Surface concise natural-language summaries, not JSON. - Use this phase flow exactly: `intake -> extract -> clarify -> price -> confirm -> generate -> revise`. - Do not enter `price` until you have enough identity and condition detail to research comps responsibly. - Do not enter `generate` until the blocking missing facts are resolved or the seller explicitly chooses to skip a marketplace. - Default pricing posture is `priced to sell` unless the seller asks for a different goal. - Only generate `TCGPlayer` output when `card name`, `game`, and `set` are known. ## Reference Routing - Open `references/workflow.md` first for the end-to-end seller flow and the hidden reviewed-item record. - Open `references/extraction.md` when you are turning images into item facts, condition notes, missing facts, or uncertainties. - Open `references/pricing.md` when you are ready to research live comps and suggest a price. - Open `references/final-output.md` immediately before drafting the final seller-facing response. - Open only the marketplace briefs the seller selected: - `references/marketplaces/ebay.md` - `references/marketplaces/mercari.md` - `references/marketplaces/facebook-marketplace.md` - `references/marketplaces/craigslist.md` - `references/marketplaces/tcgplayer.md` - Open `references/examples.md` only when you need a compact model for tone, sequencing, or edge-case handling. ## Working Rules - Start at `intake`: confirm what the item is, what photos are available, which marketplaces the seller wants, and whether they care more about speed or margin. - Move to `extract`: inspect the images and build a provisional internal record with facts, missing fields, and uncertainties. - Move to `clarify`: ask only the highest-value follow-up questions needed to resolve identity, condition, completeness, and marketplace gating. - Move to `price`: use live comps first, then heuristics only when the market data is thin. - Move to `confirm`: summarize the reviewed item and price recommendation in prose, then invite corrections. - Move to `generate`: produce copy-paste-ready output for each selected marketplace using `references/final-output.md` plus the relevant marketplace briefs. - Move to `revise`: if the seller changes facts, price, or marketplaces, update the internal record first and regenerate only the affected output.

Meeting Prep
Never walk into a meeting unprepared again. Your agent researches all attendees before calendar events—pulling LinkedIn profiles, recent company news, mutual connections, and conversation starters. Generates a briefing doc with talking points, icebreakers, and context so you show up informed and confident. Triggered automatically before meetings or on-demand. Configure research depth, advance timing, and output format. Walking into meetings blind is amateur hour—missed connections, generic small talk, zero leverage. Use when setting up meeting intelligence, researching specific attendees, generating pre-meeting briefs, or automating your prep workflow.
