AI agent skills for better second-hand decisions

Budna Marketplace released Recommerce, a set of six portable agent skills — Buy, Kits, Inspect, Collect, Keep and Second Look — for researching second-hand purchases, installable via the Skills CLI with the command "npx skills add budna-marketplace/recommerce". Each skill runs independently on evidence the host can access, such as listings, specifications, measurements and quotes, and outputs a source-backed shortlist, inspection card or change report that separates seller claims from product documentation and unresolved condition; Budna MCP is an optional integration.

Agent skills for better second-hand decisions. Portable agent skills for researching second-hand purchases. Recommerce covers discovery, complete setups, inspection, collection planning, repair-versus-replacement decisions, and reassessment before commitment. A listing is incomplete, changing evidence. The skills distinguish what a seller claims, what product documentation supports, and what still needs verification. The objective is a suitable purchase at a supported total cost—including the option to keep an existing item. | Skill | Purpose | Output | |---|---|---| | Buy https://github.com/budna-marketplace/recommerce/blob/main/skills/recommerce-buy/SKILL.md | Find and compare potential purchases. | A source-backed shortlist with fit, complete costs, tradeoffs, and decisive unknowns. | | Kits https://github.com/budna-marketplace/recommerce/blob/main/skills/recommerce-kits/SKILL.md | Assemble a working setup from multiple items. | A compatible bill of materials, required accessories, alternatives, and one shared budget. | | Inspect https://github.com/budna-marketplace/recommerce/blob/main/skills/recommerce-inspect/SKILL.md | Assess an item before purchase or collection. | A listing-specific inspection card separating claims, useful checks, and unresolved condition. | | Collect https://github.com/budna-marketplace/recommerce/blob/main/skills/recommerce-collect/SKILL.md | Determine whether collection is practical. | A route and transport plan with measurements, disassembly constraints, costs, and blockers. | | Keep https://github.com/budna-marketplace/recommerce/blob/main/skills/recommerce-keep/SKILL.md | Compare keeping, repairing, upgrading, or replacing. | A conditional comparison of future costs, suitability, downtime, and uncertainty. | | Second Look https://github.com/budna-marketplace/recommerce/blob/main/skills/recommerce-second-look/SKILL.md | Reassess an earlier recommendation before committing. | A change report and updated decision: what changed, what remains supported, and what was not rechecked. | Each skill works independently with evidence the host can access: listings, specifications, measurements, quotes, or a previous assessment. Available read-only tools can supply current evidence; Budna MCP https://github.com/budna-marketplace/mcp is an optional integration. After installing, ask your assistant: Find a complete used cordless drill delivered to Gothenburg for under 1,000 SEK. I need it for furniture assembly and already own suitable bits. Build a two-person podcast setup from these used listings. I have a laptop and headphones; include every required connection within 2,000 SEK. Inspect this drill listing before tomorrow's viewing. Give me the checks that could change my decision, distinguishing seller claims, model documentation, and observed condition. Can I collect this wardrobe in my van? Check both access routes, packed dimensions, payload, disassembly requirements, and total collection cost. Compare this laptop repair quote with these used replacements. I need it for another year; account for downtime and costs still unconfirmed. Take a second look at yesterday's shortlist before I commit. Recheck the decisive facts and show what changes the recommendation. Provide the intended use and constraints you know. The assistant should ask only for missing information that changes the decision. See an illustrative inspection card https://github.com/budna-marketplace/recommerce/blob/main/examples/drill-inspection.md . Install directly from GitHub with the Skills CLI https://github.com/vercel-labs/skills : npx skills add budna-marketplace/recommerce The installer lets you choose the skills and supported agents. To install only Buy: npx skills add budna-marketplace/recommerce --skill recommerce-buy Add --global to make the skill available across projects. No manual clone or repository-level check tooling is needed. For other Agent Skills-compatible hosts with GitHub import, select the relevant folder in skills/ https://github.com/budna-marketplace/recommerce/tree/main/skills . Import the complete folder, including its references. Hosts without skill support cannot install these as persistent skills. - Claims retain their sources. Model specifications do not certify a particular used unit; ratings and identity badges do not establish condition. - Compare usable totals. Required accessories, fees, delivery, and collection costs belong in the decision. A current auction bid is not a guaranteed purchase price. - Respect the buyer's constraints. Do not silently relax requirements, invent availability, or fill a shortlist with unsuitable options. - Keep assessment separate from transactions. The skills do not contact sellers, reserve items, bid, or purchase. They do not certify condition, authenticity, or future availability. These are general decision workflows; examples rely on supplied or verified specifications and quotes. No workflow certifies physical condition, safe handling, repair success, or future availability. Recommerce Checks https://github.com/budna-marketplace/recommerce/blob/main/checks/README.md contains synthetic regression cases and an offline evaluation workflow. These support development, not a claim of general reliability. See CONTRIBUTING.md https://github.com/budna-marketplace/recommerce/blob/main/CONTRIBUTING.md for repository structure, development checks, and how to contribute cases or improvements.
