Usage Guidance
This skill is small and appears benign: it prints the current month's calendar and does not access the network, secrets, or other files. Two practical notes before installing: (1) SKILL.md implies a full-featured CLI ('--help', flags, piping) but the provided script ignores arguments and stdin; (2) there is no install step — to run it as 'cal-tool' you must place the script on your PATH and make it executable (or run it directly). Review the script (it’s only a few lines) and be aware it may shadow a system 'cal' if you name it similarly.
Capability Analysis
Type: OpenClaw Skill
Name: cal-tool
Version: 1.0.0
The skill is a simple utility that displays the current month's calendar. The implementation in scripts/cal.py uses standard Python libraries (calendar and datetime) without any network access, file system modifications, or suspicious logic. The SKILL.md documentation is standard and contains no malicious instructions or prompt injections.
Capability Assessment
Purpose & Capability
Name/description promise a CLI 'cal-tool' and the package includes a small Python script that prints the current month's calendar — this is proportionate and expected.
Instruction Scope
SKILL.md advertises flags, arguments, help, piping and shell integration, but the included script simply prints the current month and ignores arguments and stdin. Also there is no install instruction to make a 'cal-tool' binary available on PATH, so the SKILL.md guidance is optimistic and not fully accurate.
Install Mechanism
No install spec (instruction-only). The included script is small and local; nothing is downloaded or written to disk by an installer. Low install risk.
Credentials
No environment variables, credentials, or config paths are requested or used. The Python script uses only standard library modules (calendar, datetime).
Persistence & Privilege
Skill does not request always:true or other elevated persistence. It cannot invoke itself autonomously beyond normal platform behavior.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install cal-tool - After installation, invoke the skill by name or use
/cal-tool - Provide required inputs per the skill's parameter spec and get structured output
