使用说明 (SKILL.md)

Corespeed Excalidraw Rendering — Browser Rendering CLI

Render Excalidraw files to PNG and capture web page screenshots using headless Chrome.

Workflow

Ensure brow is installed
Install the managed browser: brow browser install
Run brow --help to see all available options
Run the rendering command

Prerequisites

If brow is not installed:

curl -fsSL https://raw.githubusercontent.com/corespeed-io/brow/main/install.sh | bash

Before first render, install the managed browser (safe to re-run):

brow browser install

Usage

Run brow --help for the full CLI reference. Quick examples:

# Render Excalidraw to PNG
brow -m excalidraw -i drawing.excalidraw -o output.png

# Screenshot a web page
brow -u https://example.com -o screenshot.png

Notes

Browser auto-managed. brow browser install downloads Chrome to a local cache. No system Chrome required.
Use timestamps in filenames: yyyy-mm-dd-hh-mm-ss-name.png.
Do not read generated images back; report the saved path only.

安全使用建议

This skill appears to do what it says: invoke the 'brow' CLI to render Excalidraw files and take screenshots. The main thing to watch for is the install method: the SKILL.md recommends running a remote install script via 'curl ... | bash', which will execute code from the internet on your machine and then download a managed Chrome binary. Before installing, consider: (1) review the install script at https://raw.githubusercontent.com/corespeed-io/brow/main/install.sh yourself instead of piping it directly to a shell; (2) prefer installing 'brow' from a package manager or official release artifacts if available; (3) run the install in a sandbox/container or on a machine where a managed Chrome download is acceptable; (4) verify the GitHub repo and project reputation (signatures, checksums, or release tags if available); and (5) ensure you are comfortable with the tool downloading browser binaries to your user cache. If you cannot or do not want to run arbitrary install scripts, do not install the CLI and avoid using this skill.

功能分析

Type: OpenClaw Skill Name: corespeed-excalidraw-rendering Version: 1.0.0 The skill employs a high-risk installation pattern in SKILL.md, using 'curl | bash' to execute a remote script from GitHub (raw.githubusercontent.com/corespeed-io/brow/main/install.sh). While the stated functionality of rendering Excalidraw files and capturing screenshots is plausible, the use of unverified remote code execution for installation and the subsequent automated download of browser binaries ('brow browser install') are significant security risks that lack transparency and auditability.

能力评估

✓ Purpose & Capability

The name/description match the actions described in SKILL.md. Requiring the 'brow' binary is appropriate for a skill that renders Excalidraw files and captures screenshots; no unrelated binaries, credentials, or config paths are requested.

✓ Instruction Scope

SKILL.md only instructs installing/using the 'brow' CLI, running 'brow browser install', and calling brow commands to render files or take screenshots. It does not instruct reading unrelated files, accessing other environment variables, or transmitting data to unexpected endpoints.

ℹ Install Mechanism

The provided install instruction pipes a script from raw.githubusercontent.com into bash (curl ... | bash). GitHub raw is a known host, but piping a remote install script to a shell executes arbitrary code on the machine and is a moderate-risk install pattern. The skill also relies on 'brow browser install' which downloads a managed Chrome binary into a local cache — expected for the tool but worth being aware of.

✓ Credentials

No environment variables, credentials, or config paths are requested. The lack of extra secrets is proportional to the stated purpose.

✓ Persistence & Privilege

The skill is instruction-only (no install spec that writes persistent configuration for the agent) and 'always' is false. It does not request permanent presence or claim to modify other skills or system-wide settings.

如何使用

确保已安装 OpenClaw（本地或 Docker 部署）
