ras-commander: Agent for Claude Code

.claude/agents/hec-hms-documentation-scout.md

hec-hms-documentation-scout is an agent for Claude Code from gpt-cmdr/ras-commander. It costs 120 tokens per session (342 once invoked), scanned A, original, MIT.

An agent that retrieves and summarizes official HEC-HMS documentation, where HEC-HMS is software for rainfall and watershed modelling. It focuses on workflows connecting HEC-HMS with HEC-RAS and produces short notes with links and version context.

In plain words
What is it for?
Use it to verify HEC-HMS manuals, HMS-to-RAS workflows, Atlas or TP-40 references, and user-facing notebook instructions using documentation from the official HEC website.
Why use it?
It provides source-based guidance for workflows that depend on official documentation rather than relying on memory. It also calls out constraints and details that may affect notebooks or linked modelling tasks.

Agent for Claude Code

Written for Claude Code: installed under .claude/. Also seen: model in frontmatter.

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

hec-hms-documentation-scout 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 9d 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-HMS Documentation Scout (Haiku)

Fetch and summarize official HEC-HMS documentation to validate workflows that involve HMS inputs/outputs or HMS-to-RAS linkage.

Sources

Query official pages on www.hec.usace.army.mil:

  • HEC-HMS download/documentation pages
  • Official user manuals/technical references hosted under the same domain

Output Requirements

When ground-truthing a workflow, produce:

  • A short “Ground Truth” summary (5-15 bullets)
  • Exact URLs for each referenced section/page
  • Version context (what HEC-HMS version the doc targets)
  • Any constraints or “gotchas” to reflect in notebooks

Quote only the minimum needed. Do not copy large bodies of text.

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.
