Usage Guidance
This skill appears coherent and implements a simple uptime checker in pure Python. Before installing/using: (1) review and run the included script locally to confirm behavior; (2) be careful when supplying Authorization or other sensitive headers via --header (those are sent to the checked URLs); (3) note the default history file (uptime_history.json) is written to the current directory—restrict filesystem permissions if that matters; (4) avoid --no-verify-ssl unless you trust the endpoint (it disables SSL checks). If you need the agent to run this skill autonomously, consider where it will run and what URLs/headers it will be given.
Capability Analysis
Type: OpenClaw Skill
Name: uptime-checker
Version: 1.0.0
The uptime-checker skill is a standard utility for monitoring website availability and response times using Python's standard library (urllib). The code in scripts/uptime_check.py is well-structured, lacks external dependencies, and performs only the actions described in SKILL.md, such as making HTTP requests, measuring latency, and maintaining a local history file.
Capability Assessment
Purpose & Capability
Name/description align with included Python script: it performs HTTP(S) checks, measures response time, follows redirects, validates SSL, and tracks history. No unrelated credentials, binaries, or services are requested.
Instruction Scope
SKILL.md instructs running the bundled script with CLI flags; the script only reads URLs from arguments or a provided file and reads/writes a local history file. It does not attempt to scan other parts of the filesystem, exfiltrate data to third parties, or access unspecified environment variables.
Install Mechanism
No install spec is provided and the skill is instruction-only aside from the included Python script. The script uses only the Python standard library (urllib, ssl, json, pathlib), so no external packages or downloads are required.
Credentials
The skill requests no environment variables or credentials, which is appropriate. Caution: the CLI supports custom headers (e.g., Authorization) and these will be sent to target endpoints if supplied; the tool also writes a local history file (default uptime_history.json) which could contain result metadata. Ensure you don't pass secrets via --header unless intended and protect the history file if it will contain sensitive target metadata.
Persistence & Privilege
The skill is not always-enabled and does not modify other skills or global agent settings. It does persist check results to a local history file when --save is used, which is expected behavior for a monitor tool.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install uptime-checker - After installation, invoke the skill by name or use
/uptime-checker - Provide required inputs per the skill's parameter spec and get structured output
