obspy-data-api

obspy-data-api is a skill for Claude Code, Codex from benchflow-ai/skillsbench. It costs 65 tokens per session (1,509 once invoked), scanned A, original, Apache-2.0.

A guide to ObsPy, a Python framework for reading and working with seismological data. It explains how waveform files become streams of time-series traces with measurements and recording metadata.

In plain words
What is it for?
Use it to load, inspect, filter, taper, and resample seismic recordings, or prepare them for earthquake-analysis models.
Why use it?
It removes the need to learn how each common earthquake waveform file format is represented before using signal-processing tools.

About the project

SkillsBench is a benchmark for measuring how effectively AI agents use modular skills—folders containing instructions, scripts, and resources—to complete specialized tasks. It helps researchers and developers evaluate both skill quality and agent behavior, including tasks that require combining multiple skills. The catalogue’s skills and instructions are evaluated as part of this workflow.

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

obspy-data-api 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 4d 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.

ObsPy Data API

Waveform Data

Summary

Seismograms of various formats (e.g. SAC, MiniSEED, GSE2, SEISAN, Q, etc.) can be imported into a Stream object using the read() function.

Streams are list-like objects which contain multiple Trace objects, i.e. gap-less continuous time series and related header/meta information.

Each Trace object has the attribute data pointing to a NumPy ndarray of the actual time series and the attribute stats which contains all meta information in a dict-like Stats object. Both attributes starttime and endtime of the Stats object are UTCDateTime objects.

A multitude of helper methods are attached to Stream and Trace objects for handling and modifying the waveform data.

Stream and Trace Class Structure

Hierarchy: StreamTrace (multiple)

Trace - DATA:

  • data → NumPy array
  • stats:
    • network, station, location, channel — Determine physical location and instrument
    • starttime, sampling_rate, delta, endtime, npts — Interrelated

Trace - METHODS:

  • taper() — Tapers the data.
  • filter() — Filters the data.
  • resample() — Resamples the data in the frequency domain.
  • integrate() — Integrates the data with respect to time.
  • remove_response() — Deconvolves the instrument response.

Example

A Stream with an example seismogram can be created by calling read() without any arguments. Local files can be read by specifying the filename, files stored on http servers (e.g. at https://examples.obspy.org) can be read by specifying their URL.

>>> from obspy import read
>>> st = read()
>>> print(st)

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.
