mcp-playwright-browser: Instructions file for Gemini CLI

GEMINI.md

mcp-playwright-browser GEMINI.md is an instructions file for Gemini CLI from Mhrnqaruni/mcp-playwright-browser. It costs 957 tokens per session, scanned A, original, ISC.

Project instructions for Gemini CLI, a command-line AI assistant, that require browser actions through a Playwright MCP server and set rules for reading job-application files.

In plain words
What is it for?
Use them when applying for jobs with browser automation, CVs, cover letters, and job descriptions stored in project folders.
Why use it?
They give the agent a consistent way to inspect browser pages and CV or job files while choosing document-structure checks before visual inspection.

Instructions file for Gemini CLI

Written for Gemini CLI: the file is GEMINI.md.

This is Mhrnqaruni/mcp-playwright-browser's own configuration. It tells Gemini CLI how to work on mcp-playwright-browser itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything mcp-playwright-browser configures →

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

mcp-playwright-browser GEMINI.md 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 2mo 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.

Gemini Project Instructions (Auto)

Always Use MCP Server

Use MCP server playwrightBrowser for all browser actions.

Reading CV / Job Files

  • Prefer MCP file tools (avoid built-in ReadFile/Shell because workspace restrictions can fail unexpectedly):
    • Use files.list_dir to locate CV/cover letter/jobdescription under Applied Jobs/<job-folder>/.
    • Use files.read_text for *.md/*.txt.
    • Use files.read_pdf_text for *.pdf.
    • If the needed info is missing/unreadable: ask the user (do not hunt/scan across folders).

DOM vs Visual

  • Prefer DOM actions first.
  • Set capture profile at start of work:
    • Call browser.set_capture_profile with profile: "light" unless the user asks for debug-level detail.
  • Follow this capture ladder (least expensive first):
    1. browser.snapshot with detail: "low"
    2. browser.list with detail: "low"
    3. browser.query_dom with detail: "low" for targeted reads
    4. browser.take_snapshot with detail: "low" only when uid targeting is needed
    5. browser.visual_snapshot with detail: "low" only as last resort
  • Use detail: "high" only when low detail is insufficient.
  • Do not repeat browser.take_snapshot / browser.visual_snapshot unless one of these is true:
    • domVersion changed
    • you intentionally scrolled and need a fresh scan of newly visible content
    • MCP returned STALE_REF
    • target cannot be found after browser.wait_for
    • user explicitly asked for a fresh visual check
  • If browser.list reports needsScrollForMore: true or hasOffViewportCandidates: true, scroll and run browser.list again before concluding the page is complete.

Element IDs (Critical)

  • elementIds are short-lived. After any click, dropdown, or navigation:
    • call browser.list (or browser.visual_snapshot) again
    • do not reuse old element IDs
  • Waiting: use browser.wait_for (selector/text/uid) instead of fixed sleeps.

Multi-Tab / Popups

  • Popup tools do not auto-select new tabs by default.
  • If a popup/new tab opens, always use:
    • browser.list_pages
    • browser.select_page
    • browser.close_page

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.
