README (SKILL.md)
Heliospice
Query spacecraft and planetary ephemeris data using SPICE kernels.
Setup
pip install heliospice
What You Can Query
Spacecraft (36+): Parker Solar Probe, Solar Orbiter, Juno, Cassini, Voyager 1/2, Mars 2020, MRO, New Horizons, Europa Clipper, Psyche, BepiColombo, JUICE, Lucy, Galileo, Dawn, MESSENGER, and more...
Planets: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto
Moons: Moon, Titan, Europa, Ganymede, Io, Phobos, Deimos, and many more
Other: Sun, asteroids, comets, Solar System Barycenter
Tools
get_spacecraft_ephemeris— Position at single time or timeseries (with optional velocity)compute_distance— Distance between two bodies over time range (min/max/mean, closest approach)transform_coordinates— Transform vectors between coordinate frames (RTN, J2000, ECLIPJ2000, etc.)list_spice_missions— List all supported spacecraftlist_coordinate_frames— List available coordinate framesmanage_kernels— Check status, download, load, or purge kernel cache
Examples
- "Where is Parker Solar Probe right now?"
- "What's Earth's distance from the Sun?"
- "Show me Juno's trajectory for January 2024"
- "When did Mars get closest to Jupiter in 2024?"
- "Convert this RTN vector to J2000 frame"
- "What's the current Moon position?"
Usage Guidance
This skill appears to do what it claims (SPICE-based ephemeris queries) and does not request credentials or special system access. Before installing, verify the 'heliospice' package provenance: check the PyPI/author page, source repository, and recent release history; prefer packages with an official homepage or repository. Inspect what URLs the library uses to download SPICE kernels (prefer NAIF/PSA or well-known archives) and where it caches files (so you can control disk usage). If you are unsure, install and run it in an isolated environment (virtualenv or container) and review the package source first. If you want higher assurance, ask the skill author for the package repository URL and kernel sources; lacking that, treat pip install of an unknown package as a moderate risk.
Capability Analysis
Type: OpenClaw Skill
Name: heliospice
Version: 0.4.2
The 'heliospice' skill bundle is a legitimate utility for querying spacecraft and planetary ephemeris data using SPICE kernels. The documentation in SKILL.md describes standard astronomical tools and installation via a known Python package (heliospice), with no evidence of malicious instructions, data exfiltration, or suspicious behavior.
Capability Assessment
Purpose & Capability
Name, description, and runtime tools (ephemeris queries, coordinate transforms, kernel management) are coherent for a SPICE-based ephemeris/query tool. No unrelated credentials, binaries, or config paths are requested.
Instruction Scope
SKILL.md is instruction-only and stays on-topic: it recommends 'pip install heliospice' and lists functions (get_spacecraft_ephemeris, compute_distance, manage_kernels, etc.). However, 'manage_kernels' implies downloading and caching SPICE kernels; the SKILL.md does not document where kernels are fetched from, what cache paths are used, or how much data may be downloaded. That network/disk IO is reasonable for the stated purpose but under-specified.
Install Mechanism
There is no formal install spec in the registry; SKILL.md suggests installing via pip. Installing an arbitrary PyPI package executes third-party code locally (moderate-risk action). This is expected for a Python library but the skill lacks provenance (no homepage, unknown source) which raises the need for cautious vetting.
Credentials
The skill requests no environment variables, credentials, or config paths. The lack of extra secrets is appropriate for a read-only ephemeris/query tool.
Persistence & Privilege
always is false and the skill is user-invocable; it does not request persistent/privileged agent settings. Nothing in SKILL.md indicates it will change other skills or system-wide agent settings.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install heliospice - After installation, invoke the skill by name or use
/heliospice - Provide required inputs per the skill's parameter spec and get structured output
