Unpopular opinion: big skill packs make Claude Code worse for client work. Every extra skill is another chance for the wrong one to trigger, and none of them know which client you're working on. So I went the other way and kept only the 5 procedures I actually use every week, and open-sourced them: 1. client-workspace: one folder per client with its own rules, voice and approved claims, so Client A's tone never ends up in Client B's email 2. scope-guard: checks every "can you just quickly..." against the signed scope, quotes the extra, and drafts a polite reply (offers a paid add-on or a swap) 3. quick-quote: prices a project from 6 numbers about the client's workflow instead of your hours, and tells you when you're underquoting 4. offer-builder: turns "I do AI automation" into a fixed-scope offer with a price ladder 5. cold-email-agency: 4-step outreach sequences for small business owners There's also a full worked example (a fictional plumbing company) so you can see a real scope check end to end: 3 asks in one client email, one in scope, two quoted, reply drafted.
