之前: Evening radar, Tue 2026-10-13, 20:00 America/New_York. Window 08:00 to 20:00. 214 signals: HN 61, Product Hunt 19, YC 6, GitHub 38, Reddit 44, X 41, new sites 5. Builder profile: solo, Next.js and Supabase, 10 hours a week.
之后: Build candidate, 16/20: per-developer cost tracking for AI coding agents, seen in 3 runs. Today: a Show HN at 142 points, an r/SaaS thread on a $4,000 monthly agent bill (88 comments), an X post asking for this at 1,900 likes, and a repo up 870 stars. The 2 tools found track one agent each. First version, about 3 weeks at your hours: import usage from 3 agents and flag runaway runs. 2 Watch ideas follow.
