browser-debug

browser-debug is a skill for Claude Code from atagon-GmbH/kogiqa-mcp. It costs 45 tokens per session (323 once invoked), scanned A, original, MIT.

A browser-based debugging procedure for investigating layout problems, broken pages, console errors, and failed network requests in a running web app.

In plain words
What is it for?
Use it to inspect console and network activity, reproduce interactions, examine page structure, test viewport sizes, and verify minimal source changes.
Why use it?
It turns a vague browser problem into reproducible steps, observed behavior, a likely cause, and a checked fix.

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

browser-debug 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 2d 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

Debug a web app in the browser

Use the kogiQA browser tools to reproduce, inspect, and diagnose front-end problems. The browser is selector-free: describe what you want in natural language, then act on the tool results.

Workflow

  1. browser_navigate to the page under test.
  2. browser_get_console_log to read the current console messages. Clear the picture by revisiting the page after a reload if the log is stale.
  3. browser_get_network_history to spot failed requests (4xx/5xx) and slow endpoints.
  4. Reproduce the issue with browser_click, browser_type, browser_scroll, browser_hover, and browser_keypress.
  5. Inspect layout with browser_check_structure on the element that looks wrong, and browser_resize to test other viewport widths.
  6. browser_screenshot only when you need a visual record; prefer text tools to save tokens.

Reporting

Report findings in this order: the repro steps, the observed behavior, the likely cause, and a concrete fix. When you edit source files, keep the change minimal and re-run the repro with the browser tools to confirm the fix.

Never invent console output or network responses. Only report what the tools returned.

Changes

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.
