apply-style

A command that applies formatting and presentation standards to a data-science notebook or script, including colors, layout, and printed output.

In plain words
What is it for?
Use it to route a notebook or script through the data-science styling procedure. It is intended for fixing visual formatting and print patterns.
Why use it?
It removes repetitive manual cleanup when code or notebook output is difficult to read or does not follow the project's style.

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

apply-style 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 2d 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

Apply Rich Styling

Invoke the datascience:apply-style skill and follow it exactly. It owns the whole procedure; this command only routes into it.

Pass the remainder of this invocation through unchanged as the skill's arguments.

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.
