安全使用建议
This appears to be a legitimate STAC-based Sentinel downloader, but take these precautions before running: 1) Run the scripts in a Python virtual environment (or container) to avoid global pip installs. 2) Test with small --limit values and a small bbox to confirm behavior before large downloads. 3) Verify the STAC API endpoint you use — pointing to an untrusted custom STAC can cause the tool to download data from arbitrary hosts. 4) Ensure you have sufficient disk space and bandwidth; downloads may be large. 5) If you need access to protected data sources, prefer to supply credentials manually and review or extend the code to handle auth securely (the skill currently does not manage secrets). 6) Review the included sentinel-download.py if you want to confirm there is no additional telemetry or hidden network behavior (the provided code shows only the expected STAC/search and asset GET requests).
功能分析
Type: OpenClaw Skill
Name: sentinel-downloader-skill
Version: 1.0.2
The skill is a legitimate utility designed to search and download Sentinel satellite imagery using standard SpatioTemporal Asset Catalog (STAC) APIs from providers like Microsoft and AWS. The implementation in `sentinel-download.py` and its shell wrapper `sentinel-download.sh` uses standard libraries (requests, pystac-client) and follows the stated functionality without any evidence of malicious intent, data exfiltration, or prompt injection. While the shell script automatically installs dependencies if missing, this is a documented behavior consistent with the tool's purpose.
能力评估
Purpose & Capability
Name/description match the delivered files and behavior: the scripts query STAC endpoints and download assets. Declared/default STAC endpoints (Microsoft Planetary Computer, AWS Earth Search) are appropriate. No unrelated credentials, binaries, or config paths are requested.
Instruction Scope
SKILL.md and the bash wrapper instruct the agent to run the included Python script which: posts to a STAC /search endpoint, parses results, and downloads asset URLs to disk. This stays within the stated purpose. Notes: the tool can download large files and will write them to the filesystem; it accepts a custom --stac-api so if the user points to an arbitrary or malicious STAC endpoint it could download assets from arbitrary hosts. The scripts also attempt to pip-install dependencies if missing (global installs).
Install Mechanism
No formal install spec in registry; this is instruction/code-only. Dependencies are installed via pip as documented and the bash wrapper will auto-install missing Python packages. This is common but performs network fetches and writes to disk (global Python package installation unless the user uses a virtualenv). There are no downloads from obscure URLs or archive extracts in the package itself.
Credentials
The skill declares no required environment variables or credentials, which matches the code. The README notes some data sources may require registration; the tool does not embed or request secrets—if users need authenticated STAC access they would need to supply credentials separately (not handled automatically by the skill).
Persistence & Privilege
The skill does not request always:true and does not modify other skills or system-wide agent settings. Its persistent effects are limited to installing Python packages (if user runs check/install) and writing downloaded imagery to chosen output directories.
