Mobile Debugging Methodology

A playbook for capturing JavaScript console errors on phones and tablets when desktop DevTools isn't available.

Dev & CodingIntermediate★ 401⑂ 64AI score 9/10Last updated: Sep 23, 2026

What it does

Gives Claude a situation-by-situation map of mobile web debugging options.

  • Native remote inspection: Android Chrome chrome://inspect, iOS Safari Web Inspector, Firefox about:debugging, plus Android 11+ wireless adb pair / adb connect flow
  • In-page consoles: conditional loading of Eruda and vConsole, with a feature comparison table
  • Security guardrails: never load injected consoles from a public CDN; pin packages, copy them into a same-origin /debug folder, and verify with SHA256SUMS
  • Automation: Playwright/Puppeteer mobile emulation capturing console, pageerror, and requestfailed events
  • Production monitoring: Sentry (v8 functional integrations) and LogRocket session replay
  • Extras: scrcpy screen mirroring, iOS debugging without a Mac (ios-webkit-debug-proxy, Inspect.dev), cloud real devices (LambdaTest, BrowserStack)

Who it's for

  • Frontend developers building responsive sites or mobile web apps
  • Anyone chasing a "only breaks on my phone" bug report
  • Windows/Linux users who need iOS debugging without a Mac
  • QA/CI engineers who want console logs from real devices

Example uses

  1. "Let me open my localhost:3000 dev server on a real Android phone and see the console" → guided chrome://inspect port forwarding setup
  2. "A client tablet can't be plugged in over USB but I need the errors" → conditional ?eruda=true loader plus the same-origin asset checklist
  3. "Script a capture of all console errors at an iPhone 15 viewport" → Playwright device emulation with JSON log output

Let Claude do it — paste this into Claude Code

Install the skill I found on Claude Skill Mart.
Copy the dev-toolkit/skills/mobile-debugging folder from the GitHub repo jamditis/claude-skills-journalism into my ~/.claude/skills/mobile-debugging/.
When it's done, tell me in one line what this skill can do.

Install with a command instead

git clone https://github.com/jamditis/claude-skills-journalism.git && mkdir -p ~/.claude/skills && cp -r claude-skills-journalism/dev-toolkit/skills/mobile-debugging ~/.claude/skills/

⚠ This is a third-party skill. Check the source repository before installing.

  1. Open a terminal.
  2. Clone the repository: git clone https://github.com/jamditis/claude-skills-journalism.git
  3. Create the skills folder: mkdir -p ~/.claude/skills
  4. Copy the skill: cp -r claude-skills-journalism/dev-toolkit/skills/mobile-debugging ~/.claude/skills/
  5. Verify that ~/.claude/skills/mobile-debugging/SKILL.md exists.
  6. Restart Claude Code and ask something like "help me debug console errors on my phone" to trigger it.
  7. (Optional) Install adb (Android Platform Tools) for Android work, and Node.js plus npx playwright install for the automation recipes.
