Form 4797
Use this skill when a sole proprietor, single-member LLC, S-corp owner, or rental real estate investor disposes of property used in a trade or business and needs to fill out IRS Form 4797. Triggers on phrases like "sold business equipment", "sold rental property", "sold vehicle used for business", "depreciation recapture", "Section 1231 gain", "1245 recapture", "1250 recapture", "Form 4797", "what tax do I owe on selling my truck", "what tax on selling my rental". Do NOT use for personal stock/crypto sales (use form-8949 skill), Schedule C ordinary inventory sales (Schedule C Line 1 on the schedule-c skill), or like-kind exchanges (Form 8824 — a different form that defers gain rather than recognizes it).

From the source SKILL.md
This skill produces an audit-grade draft of Form 4797 from the user's disposition data, prior depreciation history, and 5-year §1231 history. It walks through the form's three (sometimes four) parts in the right order, applies §1231 / §1245 / §1250 / §179 / §280F rules correctly, and emits a deliverable the user can transcribe to a paper or e-file form with confidence.
