emem-locate-and-recall

emem-locate-and-recall is a skill for Claude Code from Vortx-AI/emem. It costs 109 tokens per session (1,345 once invoked), scanned A, original, Apache-2.0.

A location lookup and recall tool for Earth-observation measurements. It turns a place name into an emem cell64 location code and retrieves signed facts such as weather, vegetation, elevation, or soil data.

In plain words
What is it for?
Use it to answer measurement questions about named places, including temperature, vegetation index, elevation, and soil properties, or to request a location preview when you already have a cell64 code.
Why use it?
It removes the need to find the location code and query the measurement service separately, while flagging fallback place matches as less reliable.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

emem-locate-and-recall scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 13d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

emem-locate-and-recall

This skill turns a place name into signed Earth-observation facts in two REST calls.

When to invoke

The user asks about a measurable geospatial fact at a named place:

  • "What's the current 2 m air temperature in Bengaluru?"
  • "Show me the NDVI in the Sundarbans."
  • "How does the soil pH look in central Iowa?"
  • "What's the elevation of Mount Kilimanjaro?"

If the user has a cell64 already (a string like defi.zb493.xoso.zcb6a), skip the locate step and go straight to /v1/recall. If they want a thumbnail (visual preview) instead of numeric facts, use GET /v1/cells/{cell64}/scene.png directly.

How to invoke

The endpoint is https://emem.dev. Reads are public.

Step 1 — resolve the place name

curl -sf -X POST https://emem.dev/v1/locate \
  -H 'content-type: application/json' \
  -d '{"q":"Bengaluru, India"}' | jq '.cell64, .place_label, .via'

via reports how the name was resolved (embedded, cache, photon, nominatim, fallback). Treat via=fallback as low-confidence and ask the user to clarify.

Step 2 — recall the band(s)

curl -sf -X POST https://emem.dev/v1/recall \
  -H 'content-type: application/json' \
  -d '{"cell":"<CELL64_FROM_STEP_1>",
       "bands":["weather.temperature_2m","indices.ndvi"]}' \
  | jq '.facts[] | {band, value, unit, signed_at}, .receipt.fact_cids[]'

The response carries .facts[] (with value, unit, signed_at, signer_pubkey_b32) and .receipt (Ed25519 signature, fact_cids, schema_cid, registry_cid). The fact_cids[i] is a durable handle — re-fetching that CID from any responder in any year returns the same bytes.

Picking bands

The full band list is at https://emem.dev/v1/bands (124 auto-materializable bands, 1792 total dims). Common picks:

  • Weather: weather.temperature_2m, weather.precipitation_mm, weather.relative_humidity_2m, weather.wind_speed_10m
  • Air quality: cams.pm25, cams.no2, cams.aod_550
  • Climate: era5.t2m, era5.precip (1940→present hourly)
  • Vegetation: indices.ndvi, indices.evi, modis.ndvi_mean
  • Elevation: copdem30m.elevation_mean, gmrt.topobathy_mean
  • Land cover: esa_worldcover.lc_2021
  • Embeddings: geotessera (128-D, default 2024 vintage); the responder also ships geotessera.{2017..2024} for per-year and geotessera.multi_year (1024-D = 8×128 stacked).

emem-locate-and-recall is a skill published in the GitHub repository Vortx-AI/emem (56 stars, last pushed yesterday), licensed Apache-2.0. It adds 109 tokens to every session and 1,345 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
