neqsim-firewater-deluge-design

neqsim-firewater-deluge-design is a skill for Claude Code, Codex from equinor/neqsim-community-skills. It costs 97 tokens per session (4,105 once invoked), scanned A, original, Apache-2.0.

An educational calculator for screening fire-water and deluge coverage. It estimates water demand, fixed-nozzle counts and spacing, and alternatives such as protecting individual equipment or using fire monitors.

In plain words
What is it for?
Use it to scope water demand for a process area, check dedicated equipment protection, or compare a deluge grid with fire monitors.
Why use it?
It turns an early protection requirement into rough sizing figures before a full hydraulic network calculation.

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

neqsim-firewater-deluge-design 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 19d ago.

The scan reads SKILL.md. This mod also ships 4 executable files (examples/basic_firewater_deluge_design.py, src/firewater_deluge_design/__init__.py, src/firewater_deluge_design/model.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Fire-water and Deluge Coverage Design

Use this skill for public, educational fire-water coverage screening. It turns a protected area and an application rate into a water demand, a nozzle count and a grid pitch, and it tests the two alternatives that get proposed whenever a fixed deluge net is inconvenient: protecting the individual items instead of the area, and using fire monitors instead of a fixed system.

When to Use

  • A verification finding says an area lacks active fire protection and the demand must be scoped.
  • A modification adds hydrocarbon-bearing equipment to an area and the fire-water demand changes.
  • Somebody proposes fire monitors, or passive fire protection, in place of deluge.
  • You need a first nozzle count and grid pitch before a hydraulic network calculation.

Inputs

  • protected_area_m2: plan area for general area coverage, m².
  • area_rate_lpm_per_m2: application rate, (l/min)/m². Public minima are 10 for process areas and equipment surfaces and 20 for wellhead areas and riser balconies.
  • objects: tuple of (tag, surface_area_m2, rate_lpm_per_m2) for dedicated protection.
  • duration_min, foam_concentrate_percent, simultaneous_area_factor.
  • Nozzle: nozzle_k_lpm_per_sqrt_bar, nozzle_min_pressure_barg, max_spacing_m, operating_pressure_barg, coverage_efficiency.
  • Monitor: monitor_count, monitor_flow_lpm, wind_speed_m_s, fall_height_m, characteristic_dimension_m, line_of_sight_obstructed.

Outputs

  • area_demand_lpm, object_demand_lpm, total_demand_lpm, total_demand_m3_per_h, water_volume_m3, foam_concentrate_m3, object_to_area_ratio.
  • nozzle_count_from_flow, nozzle_count_from_coverage, nozzle_count, governing_criterion, grid_spacing_m, delivered_density_lpm_per_m2, pressure_adequate, density_met.
  • nominal_density_lpm_per_m2, drift_displacement_m, wind_coverage_fraction, effective_density_lpm_per_m2, verdict.
  • assumptions on every result.

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.
