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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00038 | $0.00776 |
| Opus 5 | $0.00019 | $0.00388 |
| Sonnet 5 | $0.00008 | $0.00155 |
| Haiku 4.5 | $0.00004 | $0.00078 |
Grade A, and why
tabz-browser 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 8d 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.

TabzChrome Browser Automation
Control Chrome via MCP tools for screenshots, interaction, debugging, and notifications.
Quick Start
Use mcp-cli to discover and call tools:
# Get tool schema (REQUIRED before calling)
mcp-cli info tabz/tabz_screenshot
# Call tool
mcp-cli call tabz/tabz_screenshot '{}'
Core Workflows
Screenshot a Page
# Get current tab info
mcp-cli call tabz/tabz_get_page_info '{}'
# Take screenshot
mcp-cli call tabz/tabz_screenshot '{}'
# Returns file path - use Read tool to view
Debug Network/API Issues
# 1. Enable capture BEFORE triggering action
mcp-cli call tabz/tabz_enable_network_capture '{}'
# 2. Trigger the action on page
# 3. Get failed requests (status >= 400)
mcp-cli call tabz/tabz_get_network_requests '{"statusMin": 400}'
# 4. Check console for JS errors
mcp-cli call tabz/tabz_get_console_logs '{"level": "error"}'
Test Responsive Design
# Emulate device
mcp-cli call tabz/tabz_emulate_device '{"device": "iPhone 14"}'
# Take screenshot
mcp-cli call tabz/tabz_screenshot '{}'
# Clear emulation
mcp-cli call tabz/tabz_emulate_clear '{}'
Fill and Submit Form

What ships with it
4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

tabz-browser is a skill published in the GitHub repository GGPrompts/TabzChrome (146 stars, last pushed 15d ago), licensed MIT. It adds 38 tokens to every session and 776 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings.
