neqsim-bathymetry-profile-screening

neqsim-bathymetry-profile-screening is a skill for Claude Code, Codex from equinor/neqsim-community-skills. It costs 60 tokens per session (1,403 once invoked), scanned A, original, Apache-2.0.

A seabed-depth screening tool that interpolates water depth along a route from supplied soundings, which are measured depth points. It also calculates seabed slopes and flags steep sections.

In plain words
What is it for?
It helps build a depth profile, estimate slopes between soundings, and identify sections needing further subsea engineering review.
Why use it?
It gives an early view of route shape and possible problem areas before detailed seabed-span, stability, or hydraulic design.

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-bathymetry-profile-screening 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.

The scan reads SKILL.md. This mod also ships 4 executable files (examples/basic_bathymetry_profile_screening.py, src/bathymetry_profile_screening/__init__.py, src/bathymetry_profile_screening/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.

Bathymetry Profile Screening

Use this skill for a quick, public screening of a seabed bathymetry profile along a route. Given a set of sounding points (distance along route and water depth), it sorts and linearly interpolates depth at requested distances, computes seabed slopes between soundings, and flags candidate steep sections. It is intentionally simple and should guide users toward validated free-span, on-bottom-stability, and NeqSim hydraulic workflows.

When to Use

  • When a user supplies seabed soundings along a route and wants an interpolated depth profile.
  • When an engineer needs slope screening and candidate steep-section flags for early planning.
  • When an agent should explain that validated span and stability analyses are required for design-grade work.

Inputs

  • soundings: a list of seabed points, each with distance_m (along route) and depth_m (water depth, positive downwards).
  • query_distances: optional list of distances at which to interpolate depth.
  • max_slope_deg: configurable public seabed-slope guideline (constructor, default 10 degrees).

Outputs

  • sorted_soundings: the soundings sorted by distance.
  • interpolated: depth at each requested query distance (linear interpolation).
  • slopes: per-interval seabed slope between consecutive soundings.
  • steep_sections: intervals whose slope is at or above the guideline.
  • max_slope_deg: the steepest interval slope.
  • min_depth_m and max_depth_m: shallowest and deepest soundings.
  • slope_warning: ok, watch, or high against the public slope guideline.
  • neqsim_available: whether the optional NeqSim package is importable.
  • assumptions: public assumptions and required follow-up.

Engineering Method

Soundings are sorted by along-route distance. Depth at a query distance is found by linear interpolation between the two bracketing soundings; query distances outside the sounding range are clamped to the nearest end and flagged. The slope of each interval is atan2(|depth_change|, distance_change) in degrees. Any interval at or above the max_slope_deg guideline is reported as a candidate steep section. The slope warning compares the steepest interval to the guideline: at or above is high, above 80 % is watch, otherwise ok.

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.

neqsim-bathymetry-profile-screening is a skill published in the GitHub repository equinor/neqsim-community-skills (2 stars, last pushed yesterday), licensed Apache-2.0. It adds 60 tokens to every session and 1,403 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
