predict — Pre-Implementation Multi-Persona Analysis

Structured pre-implementation review. Five expert personas assess the proposal independently, then debate, then converge on a verdict with a confidence score. Surfacing architectural, security, performance, and UX flaws before the first commit is the cheapest place to catch them.

When to invoke

Use before implementing any of:

• A new transport strategy (sapisidhash, cdp_attach, official_veo)
• Auth flow changes (new strategy, G12 bypass technique, cookie extraction)
• Selector cascade redesigns affecting ONBOARDING_SELECTORS, NEW_PROJECT_SELECTORS, FRAME_SLOTS_STRUCT
• Schema migrations in gflow_cli/data/
• New CLI surface or exit-code changes
• Any backlog item with an "investigation gate" in PLAN.md before coding
