Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00040 | $0.05001 |
| Opus 5.5 | $0.00016 | $0.02000 |
| Sonnet 5.5 | $0.00008 | $0.01000 |
| Haiku 4.5 | $0.00004 | $0.00500 |
Grade A, and why
browserwing scanned grade A with 1 finding 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 1mo 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

86% identical to browserwing-executor — 1,059 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

BrowserWing Executor API
Overview
BrowserWing Executor provides comprehensive browser automation capabilities through HTTP APIs. You can control browser navigation, interact with page elements, extract data, and analyze page structure.
Configuration
API Base URL: The BrowserWing Executor API address is configurable via environment variable.
- Environment Variable:
BROWSERWING_EXECUTOR_URL - Default Value:
http://127.0.0.1:8080 - How to get the URL: Read from environment variable
$BROWSERWING_EXECUTOR_URL, if not set, use defaulthttp://127.0.0.1:8080
Base URL Format: ${BROWSERWING_EXECUTOR_URL}/api/v1/executor or http://127.0.0.1:8080/api/v1/executor (if env var not set)
Authentication: Use X-BrowserWing-Key: <api-key> header or Authorization: Bearer <token> if required.
Important: Always construct the API URL by reading the environment variable first. In shell commands, use: ${BROWSERWING_EXECUTOR_URL:-http://127.0.0.1:8080}
Core Capabilities
- Page Navigation: Navigate to URLs, go back/forward, reload
- Element Interaction: Click, type, select, hover on page elements
- Data Extraction: Extract text, attributes, values from elements
- Accessibility Analysis: Get accessibility snapshot to understand page structure
- Advanced Operations: Screenshot, JavaScript execution, keyboard input
- Batch Processing: Execute multiple operations in sequence

curl -X GET "${EXECUTOR_URL}/api/v1/executor/help?command=extract"
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.
