## What example-plugin does, in the publisher's words

The reference Agent Plugin for this repository, copy it with just new-plugin to start anything new. Repo-wide conventions live in README.md and AGENTS.md.

plugin.json: the closed manifest schema: required $schema and name plus allowed metadata. Nothing else may appear at the top level.

skills/: two skill patterns. example-skill is stdlib-only; table-stats pulls in polars and pydantic through inline PEP 723 metadata, so it needs no install step and the directory stays copyable.

## Skills

- example-skill: Counts words, characters, and lines in text the user provides, using a bundled Python script. Use this as a starting template when adding a new skill to this repository, or when a user asks for a quick word/character/line count of some text.
- table-stats: Summarizes a CSV/TSV file's row count and per-column name, data type, and null count using polars. Use this when the user asks for a quick profile, summary, or overview of a delimited data file (CSV, TSV, etc.), such as "what's in this CSV" or "summarize this data file".

Descriptions come from the frontmatter of each SKILL.md, punctuation lightly normalized.

## MCP servers
