ras-commander-api-expert is an agent for Claude Code from gpt-cmdr/ras-commander. It costs 31 tokens per session (114 once invoked), scanned A, original, MIT.

An expert guide to the ras-commander programming library for working with HEC-RAS projects. HEC-RAS is software for modelling rivers, floods, and waterways.

In plain words
What is it for?
Use it to discover API methods, understand project tables and return values, find integration examples, and identify gaps in the library’s API documentation.
Why use it?
It helps developers find the right library methods and understand the data structures returned by them without reading the entire codebase or using unsuitable shortcuts.

Agent for Claude Code

Written for Claude Code: installed under .claude/.

This is gpt-cmdr/ras-commander's own configuration. It tells Claude Code how to work on ras-commander itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything ras-commander configures →

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

ras-commander-api-expert 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

RAS Commander API Expert

Load RAS API Discovery. Inspect current contracts and delegate focused discovery through available Claude-native workers when useful. Keep workflow policy and version discipline in the shared skill. Source search discovers APIs; project data extraction still uses public APIs.

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.
