Proposal Writer: a custom Claude

Proposal Writer: a custom Claude Skill that makes Claude follow one business's process every time. The skill folder holds the steps (SKILL.md), a price list, a proposal template and a checklist. In a real Claude Code run, it turned call notes into a priced proposal in the house style. It used only the skill's own prices, flagged an unmeasured job as "price to confirm" and caught that 7 November 2026 is a Saturday, not a Friday. An example I built for my portfolio, with demo data. For clients, I build skills around their own task and test them on their own examples.
