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 | $0.00032 | $0.00288 |
| Opus 5 | $0.00016 | $0.00144 |
| Sonnet 5 | $0.00006 | $0.00058 |
| Haiku 4.5 | $0.00003 | $0.00029 |
Grade A, and why
OpenST Skills Index 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.
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
OpenST Skills
Open-ST is an open-source spatial transcriptomics method that captures transcriptome-wide expression at sub-cellular resolution using sequencing-based spatial barcoding on Illumina flow cells.
Available Skills
Computational Analysis Pipeline
Complete end-to-end computational workflow for processing Open-ST data, covering all 6 stages from raw data to analysis-ready objects.
Skill file: openst_computational.md
When to use:
- Processing raw Open-ST BCL/FASTQ files
- Running spacemake for transcriptomic alignment
- Aligning spatial coordinates to tissue images
- Segmenting cells and assigning transcripts
- Reconstructing 3D spatial data from serial sections
- Performing downstream exploratory analysis on Open-ST data
Using Skills
- Read the computational pipeline skill for the full step-by-step workflow
- Follow stages sequentially: Each stage depends on the previous one
- Check system requirements: 128 GB RAM recommended, GPU for segmentation/alignment
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

OpenST Skills Index is a skill published in the GitHub repository aristoteleo/PantheonOS (484 stars, last pushed today), licensed BSD-2-Clause. It adds 32 tokens to every session and 288 once invoked, about $0.0002 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.
