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.

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 | $0.00079 | $0.04477 |
| Opus 5 | $0.00039 | $0.02239 |
| Sonnet 5 | $0.00016 | $0.00895 |
| Haiku 4.5 | $0.00008 | $0.00448 |
Grade A, and why
hvplot 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 6d 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.
How it starts
The opening of the file, as written. The whole thing — 339 lines — stays where its author put it; the contents beside it link to each section on GitHub.
hvPlot
This skill provides correct patterns and common pitfalls for hvPlot to visualize data interactively.
Before plotting, consider: what story does the data tell? What comparison matters most? Then choose the plot type, encoding, and labels that make that story obvious. For publication-quality figures needing fine-grained control, use HoloViews directly with the Matplotlib backend instead of Bokeh.

Read these for specialized topics. Each is a standalone document you can load on demand.
- Composing Exploratory Plots — layered marks (violin/box/scatter), shared-axis layout for comparison, overlay discipline, faceting around the nested-categorical-axis limit, ordered categoricals, cross-filtering with linked selections
- Distilling Explanatory Plots — one-message charts for an audience: takeaway title, gray context + one highlight, direct inline labels, in-place annotation, killing chart junk, assuming no interaction
Lookup
- Plotting options by group (axes, geographic, styling, resampling):
https://hvplot.holoviz.org/en/docs/latest/ref/plotting_options/{group}.html - Anything else: web-search
https://hvplot.holoviz.org/search.html?q=<topic>.
Dependencies
Activate the .hvplot accessor with the appropriate backend import: import hvplot.pandas, hvplot.polars, hvplot.xarray, hvplot.duckdb, or hvplot.dask. Backends like Polars and DuckDB must be installed separately. Optional: datashader for resampling, geoviews or geopandas for geographic data. Prefer the Bokeh backend (default) for interactivity, Matplotlib for static/print output, Plotly as a last resort.
What ships with it
2 files 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.

hvplot is a skill published in the GitHub repository holoviz-dev/holoviz-skills (5 stars, last pushed 4d ago), licensed BSD-3-Clause. It adds 79 tokens to every session and 4,477 once invoked, about $0.0004 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 2026-08-31.
