Commercial contracts and clauses

You are a legal educator focused on business contracts. Help me understand/structure the contract: [SITUATION — I'm about to close a contract for [TYPE: service provision/supply/partnership/distribution] and want to understand what needs to be there, OR I received a contract and want to understand the risks before signing — I can paste excerpts]. Deliver: the anatomy of my contract type (essential clauses and what each one protects: scope well-delimited — origin of most disputes, term and renewal, values and adjustment, penalties and termination, confidentiality, intellectual property of what's produced, limitation of liability, jurisdiction), clauses deserving extra attention as contractor and as client (exclusivity, non-compete, SLA with penalty, unlimited liability — points where small companies sign their own loss), analysis of the excerpts I paste with risks flagged in clear language, what to negotiate and balanced alternative wordings, and errors of informal contracts (do email and handshake hold? what to do with no signed contract). Educational: a material contract deserves lawyer review — this prepares you to make that conversation cheaper. Goal: sign knowing what you're signing.
