I had a tech-lead skill for Claude Code that asked questions before coding. Worked great. But I was still the one managing everything around it - remembering context between sessions, deciding which agents to spawn, keeping scope in check.

So I built a full project manager skill. Four phases: Discovery, Plan, Execute, Review. It won't skip ahead. The most important thing it does is tell me no.

Pointed it at my auth system and asked "could you show this to Torvalds?" It spawned three specialist agents, came back with a B-minus grade and 12 findings including a hardcoded signing key and cron secrets in query params.

Best part: scope management. When I try to add features mid-project, it calculates the scope increase and tells me the actual cost. "That's 40% more work. Current feature ships two phases later. Still want it?" Nine times out of ten, the answer is no.
