ras-commander: Skill for Claude Code

.claude/skills/hecras_export_cloud-native/SKILL.md

hecras_export_cloud-native is a skill for Claude Code from gpt-cmdr/ras-commander. It costs 48 tokens per session (219 once invoked), scanned A, original, MIT.

A command-line tool for exporting HEC-RAS model geometry and simulation results into cloud-friendly mapping formats. GeoParquet is a file format for geographic data, PMTiles is a portable map-tile format, and PostGIS stores geographic data in PostgreSQL.

In plain words
What is it for?
Use it to export mesh cells, cross sections, centerlines, depths, water-surface results, and other HEC-RAS data to GeoParquet, PMTiles, or PostGIS.
Why use it?
HEC-RAS results are not always in formats that modern data pipelines and web maps can use directly. This converts model data into formats suitable for analysis, databases, and map delivery.

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

hecras_export_cloud-native 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 25d 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.

What it actually says

HEC-RAS Cloud Native Export

Use Cloud Native GIS for the current canonical export workflow. Select ras2cng for RAS inputs, discover the installed public API/CLI and matching release guidance, and use only the dependencies needed for the requested operation. Do not preserve a historical command catalog as a current package contract.

Geometry, binary results, raster/gridded data, export-file generation, and database writes use the fuller Python/CLI path, never the informational MCP. Preserve source data, quantity/units, CRS/datum, time basis, output identity, and provenance. Export completion does not authorize upload or publication.

Changes

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.
