ras-commander: Skill for Claude Code

.claude/skills/hecras_compute_plans/SKILL.md

hecras_compute_plans is a skill for Claude Code from gpt-cmdr/ras-commander. It costs 119 tokens per session (3,075 once invoked), scanned A, original, MIT.

A tool for running HEC-RAS simulation plans, which are saved sets of model settings and inputs. It supports single-plan runs, batches of plans, parallel processing, test runs, progress reporting, and output folders.

In plain words
What is it for?
Use it to run one plan or many plans, process plans in parallel or in sequence, choose CPU usage and destinations, and monitor progress.
Why use it?
Running plans manually is repetitive, and large plan sets are harder to monitor. This organizes execution and lets developers track results as simulations finish.

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_compute_plans 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 11d 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.

Executing HEC-RAS Plans

When the user asks to run HEC-RAS plans, use RasCmdr.compute_plan() for single plans or RasCmdr.compute_parallel() for multiple. Read the primary sources below for complete parameter details.

Primary Sources

1. Execution Patterns (AGENTS.md)

Location: ras_commander/AGENTS.md

Read these sections:

  • "Plan Execution" - Core execution methods and parameters
  • "Execution Modes" - Four modes: single, parallel, sequential, remote
  • "Plan Execution Parameters" - Complete parameter reference
  • "Common Workflow Pattern" - Initialize, Execute, Extract

Key execution modes:

# Single plan
RasCmdr.compute_plan("01", dest_folder="run1", num_cores=4)

# Parallel local
RasCmdr.compute_parallel(["01", "02", "03"], max_workers=3)

# Sequential test
RasCmdr.compute_test_mode(["01", "02"])

2. Working Examples (Jupyter Notebooks)

Core execution notebooks:

  • examples/110_single_plan_execution.ipynb - Complete single plan workflow
  • examples/111_executing_plan_sets.ipynb - Plan sets and batch processing
  • examples/112_sequential_plan_execution.ipynb - Test mode execution
  • examples/113_parallel_execution.ipynb - Parallel execution with performance analysis

Advanced workflows:

  • examples/500_remote_execution_psexec.ipynb - Distributed execution
  • Real-time monitoring examples (search for stream_callback usage)

3. Code Documentation (Docstrings)

Location: ras_commander/RasCmdr.py

Read these docstrings:

  • RasCmdr.compute_plan() - Lines 139-250+ (comprehensive parameter docs)
  • RasCmdr.compute_parallel() - Parallel execution details
  • RasCmdr.compute_test_mode() - Sequential debugging mode

Callback protocol: ras_commander/callbacks.py

  • ExecutionCallback - Protocol definition
  • ConsoleCallback, FileLoggerCallback, ProgressBarCallback - Implementations

Quick Reference

Single Plan Execution

Basic pattern:

from ras_commander import init_ras_project, RasCmdr

# Initialize
init_ras_project("path/to/project", "7.0")

# Execute
RasCmdr.compute_plan("01")

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.
