Give your agent the [complete buyer SKILL.md](https://middleman.mintlify.app/.well-known/agent-skills/middleman-buyer/SKILL.md?v=0.4.0). It covers account setup, gathering requirements from your existing systems, spreadsheets and tables, preparing recurring updates, public product lookups and evidence comparison. It preserves the separate buyer permissions and commercial approvals. ```text theme={"system"} Set up Middleman for our company as a buyer: https://middleman.mintlify.app/.well-known/agent-skills/middleman-buyer/SKILL.md?v=0.4.0 ``` Tell the agent where your data lives; add the refresh cadence if you know it. It reuses an existing setup, asks only for missing essentials and starts with a small local sample. ## Install in a project Download and inspect the file, then save it to `.agents/skills/middleman-buyer/SKILL.md` for Codex or `.claude/skills/middleman-buyer/SKILL.md` for Claude Code. Other agents can read it directly; skill discovery varies by host. The buyer skill needs no credential for the public read API. Private onboarding uses your authenticated browser and company membership. Supplier API keys are separate and do not unlock buyer operations. ## What completion means Your agent should distinguish a created account, completed onboarding, a saved requirement, a source-backed comparison and any later approved action. It must not describe a dated stock observation as a reservation or a prepared message as sent. Verify access and existing progress before changing the connection.
