code-quality

code-quality is a cursor rule for Cursor from inventwo/ioBroker.life360ng. It costs 0 tokens per session (399 once invoked), scanned A, original, MIT.

A set of coding rules for a JavaScript project that connects to Life360, a location-sharing service. It covers cleanup, error handling, logging, HTTP requests, and dependency choices.

In plain words
What is it for?
Use it when changing the Life360 adapter or related Node.js code, especially around polling, API calls, shutdown handling, and linting.
Why use it?
It helps prevent timers and network activity from being left running and gives failures a predictable, diagnosable treatment.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

code-quality scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Code Quality

Style

  • async/await for asynchronous operations
  • JSDoc on public methods
  • Use this.log.* / adapter logging — never console.log in production code
  • Tabs, double quotes (see prettier.config.mjs)
  • ESLint via @iobroker/eslint-config (eslint.config.mjs) — run npm run lint after every change; CI treats warnings as errors (--max-warnings 0)

Resource cleanup

Stop polling, timers, and tracker in onUnload(); always call callback():

onUnload(callback) {
  try {
    life360Connector.disablePolling();
    life360DbConnector.clearTimers();
    this.tracker?.stop();
    callback();
  } catch {
    callback();
  }
}

Error handling

  • Wrap async/API work in try/catch; log errors, do not crash the adapter
  • Use adapter log levels: error, warn, info, debug
  • Handle network failures gracefully; set info.connection accordingly
  • HTTP 401 from Life360 → treat as expired token; set info.connection false, log warning
  • Do not retry failed API calls in a tight loop — wait for the next poll cycle

HTTP

  • Preferred: native node:https (used in lib/life360CloudConnector.js)
  • Avoid: axios, request, or other HTTP libraries

Dependencies

  • Use npm ci in CI; commit package-lock.json with package.json
  • Use @iobroker/adapter-core; avoid deprecated packages
  • Update dependencies in separate PRs only
  • Prefer built-in Node.js modules where possible

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
