Maintenance, license and trust

  • We could not determine when the repository was last updated.
  • Our last check on 2026-10-20 found the source still online.
  • No license is declared. By default that means all rights are reserved: you can read it, but reusing or redistributing it is not clearly permitted. Ask the author before building on it commercially.
  • Its trust signals score 68/100, with 3 cautions from licensing, adoption, age or documentation. These come from repository metadata, not a code audit — read the skill file before letting an agent act on it.

Safety scan

No issues found

Our scan of the whole file found no instruction hijacking, hidden characters, credential access, data exfiltration or destructive commands. An AI review of the same text found nothing harmful.

AI review by kimi-k2.7-code on 2026-09-24. Automated pattern scan on 2026-09-24. It catches known dangerous patterns, not every risk — read a skill before letting an agent act on it.

Frequently asked questions

How do I install project?
Run npx skills add heller007/Liveboard. The install tabs above show the steps for each supported agent.
Which AI agents does project work with?
It is written for Cursor, as a Cursor Rules file. Other agents that read the same format can often use it too.
Is project safe to use?
Our scan of the whole file found no instruction hijacking, hidden characters, credential access, data exfiltration or destructive commands. An AI review of the same text found nothing harmful. It declares no license and scores 68/100 on trust signals. Skills are instructions an agent will follow, so read the file before installing it and do not approve commands you do not understand.
Is project still maintained?
We could not determine when the repository was last updated.

Project: Live Lecture Board

One educator annotates PDFs/slides in handwriting; many remote viewers watch ink appear in near-real-time; sessions are recorded for faithful stroke-by-stroke replay. Single-writer INK broadcast — NOT symmetric multi-writer. Vector strokes, never video.

Stack (fixed — do not substitute)

  • pnpm monorepo. Frontend: React + Vite + TypeScript. Backend: Node + Fastify + TypeScript.
  • Realtime: raw ws (NOT Socket.IO). Drawing: Excalidraw (@excalidraw/excalidraw, MIT).
  • Shared wire protocol lives in packages/types and is the SINGLE source of truth.
  • Persistence (Postgres) and object storage (R2/S3) added ONLY when a subsystem needs them.

Architecture rules

  • Modular monolith: one server process, clean module boundaries. No microservices, no k8s.
  • Coordinates: store ink/cursor positions in NORMALIZED 0–1 document-page space, never pixels.
  • Two traffic classes: committed ink/scene = reliable + ordered; live cursor/laser = lossy, latest-wins (drop stale).
  • Capture-time timestamps: stamp events on the ADMIN machine, ms since session start. Never use server-arrival time for anything that gets recorded.

Guardrails (do NOT do these unless the active prompt says so)

  • No Redis, no auth/JWT, no database until the subsystem that introduces it.
  • No localStorage/sessionStorage anywhere.
  • Build each subsystem against FAKE neighbors first; keep the app runnable at every step.
  • TypeScript strict mode, ESM, no any. Small focused files. No premature abstraction.
  • When unsure about scope, prefer the smallest thing that passes the stated Acceptance test.

Feature / protocol tracking

  • Keep FEATURES.md updated when adding session features or changing wire messages (compat notes).
