安全使用建议
This skill appears internally consistent and low-risk: it includes a small Python script that parses cron expressions and prints human-friendly descriptions and next run times. Before installing, note that you need Python 3 available to run the script (SKILL.md uses 'python3' even though 'required binaries' metadata is empty). If you plan to let an agent execute it autonomously, confirm the agent has Python 3 and run the script in a restricted environment if you want extra caution. If you want to be thorough, you can open the included scripts (they are short and readable) and run them locally on sample cron expressions to verify behavior; the code does not perform network I/O or read/write system files or secrets.
功能分析
Type: OpenClaw Skill
Name: cronexplain
Version: 1.0.0
The skill is a legitimate utility for parsing and explaining cron expressions. The Python script (cronexplain.py) uses standard libraries (argparse, datetime) to process input and contains no network access, file system operations, or shell execution logic. No evidence of prompt injection or malicious intent was found in the instructions or code.
能力评估
Purpose & Capability
Name/description match the delivered artifacts: the repository contains a cron expression parser/explainer and a next-run calculator. There are no unrelated environment variables, binaries, or external services requested.
Instruction Scope
SKILL.md instructs running the included Python script (python3 scripts/cronexplain.py). The skill metadata lists 'zero dependencies' but does not declare 'python3' as a required binary — this is a minor inconsistency (practical requirement: Python 3 must be available to run the script). The instructions do not ask the agent to read unrelated files, access environment variables, or transmit data externally.
Install Mechanism
No install spec / no downloads. This is an instruction-only skill that ships its Python files with the skill bundle. Nothing will be fetched from external URLs or written to system paths during install.
Credentials
The skill requests no environment variables, no credentials, and no config paths. The code does not access os.environ or other secrets. There is no indication of disproportionate credential or env access.
Persistence & Privilege
always is false and the skill does not attempt to modify other skills or system-wide configuration. It only prints explanations and computed run times when executed.
