Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00043 | $0.00495 |
| Opus 5.5 | $0.00017 | $0.00198 |
| Sonnet 5.5 | $0.00009 | $0.00099 |
| Haiku 4.5 | $0.00004 | $0.00049 |
Grade A, and why
noaa-coops-water-level scanned grade A with 0 findings 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 1mo 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.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 25 lines — stays where its author put it; the contents beside it link to each section on GitHub.
NOAA CO-OPS observed water level
- Require the exact seven-digit NOAA CO-OPS station id, an explicit vertical datum, a unit system, and a timezone-qualified interval whose endpoints resolve to exact minutes and span no more than 31 days.
- Call
fetch_noaa_coops_water_levels. Usenormalize_noaa_coops_water_level_jsononly for a user-downloaded response and supply the same station, interval, datum, and units that produced it. - Preserve
provenance.requestUrl,requestSha256,responseUrl,httpStatus,rawResponseSha256,rawResponseBytes,normalizedSha256,retrievedAt, and the nested network receipt. - Keep coordinates in EPSG:4326, observation times in UTC ISO form, and water-level and standard-deviation units exactly as returned for the requested unit system. Never infer or convert the vertical datum.
- Keep missing values as null. Keep NOAA
preliminary/verifiedstate and quality flags; do not interpolate, predict, or silently promote preliminary data. - Use
vegaLitewith itscontentReceipts.timeSeriesFigurefor an installed Vega renderer,stationGeojsonfor a compatible map renderer, ortablefor data inspection. If no renderer exists, retain these deterministic artifacts and report the host-renderer boundary.
Verification
source.endpointandprovenance.responseUrlremain on the exact officialapi.tidesandcurrents.noaa.gov/api/prod/datagetterendpoint with redirects denied.- The response station matches the requested station; longitude and latitude are finite EPSG:4326 coordinates.
- Every observation is inside the requested UTC interval, timestamps are unique after normalization, and the unit plus vertical datum are explicit.
- Recompute each content receipt from canonical JSON before treating its corresponding table, GeoJSON, or Vega-Lite object as renderable evidence.
Boundary
This workflow retrieves NOAA CO-OPS observed water level only. It does not retrieve predictions, currents, meteorology, monthly means, climate grids, remote-sensing products, or causal/forecast models.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

noaa-coops-water-level is a skill published in the GitHub repository agentlas-ai/agentlas-desktop (6 stars, last pushed yesterday), licensed Apache-2.0. It adds 43 tokens to every session and 495 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-04.
