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.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00052 | $0.00846 |
| Opus 5 | $0.00026 | $0.00423 |
| Sonnet 5 | $0.00010 | $0.00169 |
| Haiku 4.5 | $0.00005 | $0.00085 |
Grade A, and why
seismic-picker-selection 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 7d 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.

Seismic Event Detection & Phase Picking Method Selection Guide
Overview: Method Tradeoffs
When choosing an event detection and phase picking method, consider these key tradeoffs:
| Method | Generalizability | Sensitivity | Speed, Ease-of-Use | False Positives |
|---|---|---|---|---|
| STA/LTA | High | Low | Fast, Easy | Many |
| Manual | High | High | Slow, Difficult | Few |
| Deep Learning | High | High | Fast, Easy | Medium |
| Template Matching | Low | High | Slow, Difficult | Few |
- Generalizability: Ability to find arbitrary earthquake signals
- Sensitivity: Ability to find small earthquakes
Key insight: Each method has strengths and weaknesses. Purpose and resources should guide your choice.
STA/LTA (Short-Term Average / Long-Term Average)
Advantages
- Runs very fast: Automatically operates in real-time
- Easy to understand & implement: Can optimize for different window lengths and ratios
- No prior knowledge needed: Does not require information about earthquake sources or waveforms
- Amplitude-based detector: Reliably detects large earthquake signals
Limitations
- High rate of false detections during active sequences
- Automatic picks not as precise
- Requires manual review and refinement of picks for a quality catalog
Template Matching
Advantages
- Optimally sensitive detector (more sensitive than deep-learning): Can find smallest earthquakes buried in noise, if similar enough to template waveform
- Excellent for improving temporal resolution of earthquake sequences
- False detections are not as concerning when using high detection threshold
Limitations
- Requires prior knowledge about earthquake sources: Need template waveforms with good picks from a preexisting catalog
- Does not improve spatial resolution: Unknown earthquake sources that are not similar enough to templates cannot be found
- Setup effort required: Must extract template waveforms and configure processing
- Computationally intensive
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-picker-selection is a skill published in the GitHub repository benchflow-ai/skillsbench (1,757 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 52 tokens to every session and 846 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.
