D3.js Visualization

Mon, 01 Jan 0001 00:00:00 +0000

This skill teaches Claude to build D3.js charts and interactive data visualizations, handling D3’s verbose selection-and-binding API on the model’s behalf.

Why a skill for this

D3’s power comes with a steep, idiosyncratic API that’s easy to get subtly wrong. A skill that already knows D3’s conventions produces working visualizations faster than re-deriving the pattern from documentation each time.

CSV Data Summarizer

Mon, 01 Jan 0001 00:00:00 +0000

The CSV Data Summarizer skill automatically profiles a CSV file and produces insights with visualizations, without needing a detailed prompt describing what to look for.

Why a skill for this

Most CSV exploration starts with the same handful of questions — distributions, outliers, missing data, obvious correlations. Automating that first pass saves the back-and-forth of asking for it column by column.

Claude Scientific Skills

Mon, 01 Jan 0001 00:00:00 +0000

This is a collection of ready-to-use skills for working with specialized scientific libraries and databases, packaging domain knowledge that’s otherwise scattered across niche documentation.

Why a skill for this

Scientific computing libraries often have small, specialist user bases and thin documentation. Bundling working knowledge of them as skills saves re-deriving usage patterns from source code or sparse docs each time.

Postgres Query Skill

Mon, 01 Jan 0001 00:00:00 +0000

This skill executes safe, read-only SQL queries against PostgreSQL databases, with multi-connection support and defense-in-depth safeguards against destructive statements.

Why a skill for this

Letting a model run arbitrary SQL against a real database is risky without hard guardrails. Restricting the skill to read-only queries with explicit safeguards makes database exploration usable without risking accidental writes.

Jupyter Notebook Skill

Mon, 01 Jan 0001 00:00:00 +0000

This curated Codex skill authors and edits Jupyter notebooks programmatically, handling the notebook’s cell-and-metadata JSON structure correctly.

Why a skill for this

Notebook files are structured JSON with execution metadata and outputs, not plain text — editing them without understanding that structure easily corrupts the file. A skill that knows the format keeps notebooks valid while editing.
