Guidance the server publishes about itself, which clients place ahead of the tool catalog so the model reads it before choosing anything.

Tools

Functions exposed to the LLM to take actions

NameDescription
search_imageryA

List satellite scenes covering a place and date range (newest first).

Give either bbox = [west, south, east, north] or a point (lon, lat), in WGS84 degrees. Dates are YYYY-MM-DD (inclusive). collection is "sentinel-2-l2a" or "landsat-c2-l2". max_cloud is the scene-level cloud cover limit in percent; limit caps results (1-50). Returns scene IDs, acquisition times, cloud cover and tile, plus sources/checks/notes.

ndvi_timeseriesA

Sentinel-2 L2A NDVI at a point for every usable scene between start and end (YYYY-MM-DD).

NDVI is averaged over clear 10 m pixels within buffer_m metres (0-500) of the point; clouds, cloud shadow and cirrus are masked with the Scene Classification Layer. Fully cloudy dates are skipped and listed. max_scene_cloud (percent) pre-filters scenes before pixel masking. Each date reports ndvi_mean, ndvi_std, clear_pixels, clear_fraction, item_ids and a low_confidence flag (clear_fraction < 0.5) and a suspect_dip flag (one-date drop > 0.2 that recovers, usually missed haze). Ranges longer than 2 years are refused.

land_coverA

ESA WorldCover 2021 (10 m) land-cover class at a point, e.g. 40 = Cropland.

With buffer_m > 0 (max 500) also returns the percent share of each class within that radius.

elevationA

Copernicus DEM GLO-30 elevation (metres, EGM2008) at a point, plus slope in degrees (Horn 3x3 on a 30 m grid) and local relief in a 150 m window.

area_summaryA

Quick report for a small box [west, south, east, north] (max 25 km^2): 2021 land-cover shares, elevation and slope statistics, and NDVI from the most recent Sentinel-2 scene in the last days_back days (15-365) in which at least 60% of the box is clear.

verifyA

Independent sanity checks at a point. Recomputes NDVI for the latest clear scene (last days_back days) directly from the raw B04/B08/SCL bands on the scene's native grid and compares it with the ndvi_timeseries pipeline; compares native vs regridded elevation and land cover; and checks land cover against NDVI. Returns status pass / warn / fail with each check's detail.

TDQS

A3.9/5.0

Scored across 6 tools

Disambiguation4/5

Each tool has a distinct purpose: scene search, NDVI time series, land cover, elevation, area report, and verification. The only mild overlap is area_summary, which composites land_cover/elevation/NDVI outputs, but its description clearly frames it as a small-box quick report, distinguishing it from the point-based tools.

Naming Consistency3/5

All names are snake_case, but conventions are mixed: some are verb_noun (search_imagery, verify) and others are bare nouns (land_cover, elevation, ndvi_timeseries, area_summary). Readable but not a predictable pattern.

Tool Count5/5

Six tools is well-scoped for an Earth-observation analysis server; each tool covers a distinct analysis primitive with no filler.

Completeness4/5

Core workflows—scene discovery, NDVI, land cover, elevation, summary, and verification—are covered. However, search_imagery returns scene IDs without any tool to fetch actual assets/pixels or download URLs, which is a notable gap for an imagery server, though analysis workflows are not blocked.
