seismic-workflow

seismic-workflow is a command for Claude Code from SteadfastAsArt/geoscience-skills. It costs 11 tokens per session (450 once invoked), scanned A, original, MIT.

A guided workflow for analysing seismic data, which records vibrations travelling through the ground. It takes the work from loading files through signal processing, rock-physics calculations, and visualisation.

In plain words
What is it for?
It is for loading SEG-Y and other seismology files, filtering and analysing signals, studying rock and fluid properties, examining surface-wave dispersion, and creating 2D or 3D plots.
Why use it?
It helps choose the right tool and order of steps for different seismic file formats and analysis goals.

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

seismic-workflow 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 8d 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

Seismic Data Analysis Workflow

Guide the user through a seismic data analysis pipeline. Determine the appropriate skill chain based on their data and goals.

Decision Tree

  1. What format is the data?

    • SEG-Y (.sgy, .segy) → Use segyio skill for loading
    • MiniSEED / SAC / other seismological formats → Use obspy skill for loading
    • Already loaded as numpy array → Skip to processing
  2. What processing is needed?

    • Filtering, detrending, spectral analysis → Use obspy skill
    • Rock physics (AVO, fluid substitution, elastic moduli) → Use bruges skill
    • Surface wave dispersion → Use disba skill
  3. Visualization needs?

    • 2D section / wiggle plots → matplotlib (built-in)
    • 3D seismic volume rendering → Use pyvista skill

Skill Chain

segyio (load SEG-Y) → obspy (signal processing) → bruges (rock physics) → pyvista (3D viz)
                                                  ↘ disba (dispersion)

Step Prompts

For each step, invoke the relevant domain skill and follow its guidance.

Step 1: Data Loading

  • Load seismic data and inspect geometry
  • Check trace headers, inline/crossline ranges
  • Validate sample rate and trace length

Step 2: Quality Control

  • Check for dead traces and amplitude anomalies
  • Validate geometry consistency
  • Review amplitude statistics

Step 3: Processing

  • Apply filters (bandpass, notch) as needed
  • Detrend and remove DC offset
  • Apply gain corrections if needed

Step 4: Analysis

  • Rock physics: AVO analysis, fluid substitution
  • Surface waves: compute dispersion curves
  • Attributes: amplitude, phase, frequency

Step 5: Visualization

  • 2D: seismic sections, amplitude maps
  • 3D: volume rendering, horizon surfaces

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.

seismic-workflow is a command published in the GitHub repository SteadfastAsArt/geoscience-skills (57 stars, last pushed 5mo ago), licensed MIT. It adds 11 tokens to every session and 450 once invoked, about $0.0001 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 2026-08-30.
