How good is your vibe coding, really? Most developers have no idea how their prompting actually performs. No score. No signal. Just the next session — and a quietly burning token bill. Optra Prism is the first scoring layer for AI-assisted coding. We sit silently behind your Claude Code session, log every prompt, and grade the work. When the session ends, you get a PRISM score (0–10), one specific fix to try next time, and a turn-by-turn replay that shows exactly where the tokens leaked. No interruptions while you code. No dashboards to babysit. The signal arrives after the work is done — in your inbox or Slack, the same way a great code review does. Built for the Claude Code developer first. Codex and Gemini are next. What you get: — PRISM Score after every session, with the one anti-pattern most worth fixing — Session replay annotated turn-by-turn — see the prompt that triggered the retry storm — Token efficiency analysis: where your plan is being burned, and how to recover ~30% of the waste — Weekly digest by email or Slack — Free forever for individual developers For teams, Prism rolls up into a Team Score dashboard, a coaching digest that names who needs a 1:1 and the exact pattern to address, and cost attribution by developer, project, and team — the first time AI spend has a breakdown your CFO can actually read. Why this exists: — 73% of developers have no idea how their prompts actually perform — ~30% of token spend is wasted on vague, over-injected prompts — Zero tools score the work — until now Stop vibing blind. Start measuring. → Free forever for individuals. No credit card.
