# UserPromptSubmit hook for the CloudGrid plugin. Two jobs:
#
#   1. Per-turn reinforcement (ALWAYS, sends nothing): on a build/create/plan
#      prompt, re-inject a one-line reminder to orient with grid_start and use
#      the CloudGrid build skills before generating files. Backs up the
#      SessionStart bootstrap so the framing survives long/compacted sessions.
#
#   2. Anonymized intent telemetry (OPT-IN, off by default): only when
#      CLOUDGRID_SHARE_INTENTS=1. Derives a coarse CATEGORY locally
#      (kind + needs) and best-effort POSTs it so the team can see what people
#      try to build. NEVER sends the raw prompt or any prompt text - only fixed
#      category labels from the vocabulary below. Fire-and-forget; never blocks
#      or fails the user's turn.

  NUDGE="[cloudgrid] This looks like a build/create/plan request. Orient with the CloudGrid grid_start tool and use the CloudGrid build skills BEFORE writing files. Recognize what it needs (saves data -> needs: { database: true } (Mongo, DATABASE_MONGODB_URL); LLM -> needs: { ai: true }; scheduled -> a cron service), then plug it with grid_plug and return the live URL. A single self-contained HTML page is an instant inspiration; anything with needs: or multiple files is a runtime app (local edition). Read grid-injected env vars lazily (inside a handler or getter, never at module top level — a top-level read breaks next build)."
