earthquake-phase-association

earthquake-phase-association is a skill for Claude Code, Codex from EtaYang10th/spark-skills. It costs 0 tokens per session (6,466 once invoked), scanned A, original, no licence file.

A workflow for turning seismic wave recordings into a catalogue of earthquakes. It detects P- and S-wave arrivals and groups those detections into individual events.

In plain words
What is it for?
Use it with MiniSEED waveform files and station metadata to pick seismic phases, associate them into events, and write the results to a CSV catalogue.
Why use it?
Separate arrival detections do not automatically reveal which earthquake they belong to, so event grouping is needed to build a usable catalogue.

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

earthquake-phase-association 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 13d 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.

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.

earthquake-phase-association is a skill published in the GitHub repository EtaYang10th/spark-skills (111 stars, last pushed 3mo ago), with no licence file. It costs nothing until one of its globs matches a file; then it loads 6,466 tokens. 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.
