Speedtest.net

Measure internet network speed (download, upload, ping) using speedtest-cli (Speedtest.net). Use when: user asks to "check speed", "run speedtest", "test net...

Security Scan

The skill's code and instructions are consistent with its stated purpose (wrapping speedtest-cli to run network speed tests); it requests no credentials, has no installer, and does not perform unexpected file or network access beyond what a speed test requires.

Purpose & Capability

Name/description match the included script and docs: the skill wraps the standard speedtest-cli tool to measure ping/download/upload. There are no unrelated binaries, env vars, or config paths requested.

Instruction Scope

SKILL.md and scripts/speedtest.py only instruct running the local speedtest-cli and printing results (plain text or JSON). The JSON can include server name/location, ISP, and IP — which is expected for speed tests and is documented in SKILL.md. The instructions explicitly avoid automatic installation and do not read other system files or environment variables.

Install Mechanism

There is no automated install spec bundled with the skill. setup.md recommends installing speedtest-cli via pip/apt/Homebrew — standard, low-risk guidance. The skill will not download or execute arbitrary code itself.

Credentials

The skill requires no environment variables, credentials, or config paths. This is appropriate for a simple client-side network test that uses an external Ookla service via speedtest-cli.

Persistence & Privilege

always is false and the skill does not request persistent/system-wide modifications. It runs only when invoked and does not modify other skills or agent configuration.

Assessment

This skill is internally consistent and minimal: it simply calls your locally installed speedtest-cli. Before installing/use: (1) verify you trust the source owner since repository/homepage is not provided; (2) install speedtest-cli from a trusted package source (pip/homebrew/apt) and avoid running installs as root if you don't trust the package; (3) be aware JSON output contains IP, ISP, and server location — don't share that output if it contains sensitive info; (4) the skill will perform outbound HTTPS connections to Speedtest servers (TCP 443) when run, which is expected for a speed test.

Quick Usage

python3 scripts/speedtest.py [--json] [--server SERVER_ID] [--timeout SECONDS]

Flags

Flag	Default	Description
--json	off	Output raw JSON (download/upload/ping + server info)
--server	auto	Force a specific Speedtest server ID
--timeout	120	Max seconds to wait for the test

Plain text output (default)

Ping: 45.12 ms
Download: 120.45 Mbit/s
Upload: 25.33 Mbit/s

JSON output (--json)

Returns structured data including server name/location, ISP, and IP.

Prerequisites

speedtest-cli must be installed before using this skill. See setup.md for installation instructions.

If the script reports speedtest-cli not found, do not attempt automatic installation — direct the user to setup.md and let them install it manually.

Notes

• Tests connect to the nearest Ookla/Speedtest server by default.
• Results vary by server distance, network congestion, and host resources.
• For repeated monitoring, schedule via cron with JSON output and log results.
