## Install

```sh
agentstack add skill-ntk148v-skills-summarize
```

Requires the [AgentStack CLI](https://agentstack.voostack.com/docs/cli). Works with Claude Code, Cursor, and any MCP-compatible agent.

## About

Turn “things” (URLs, PDFs, Word docs, PowerPoints, HTML pages, text files, etc.) into **Markdown** so they can be inspected/quoted/processed like normal text.

`markitdown` can fetch URLs by itself; this skill mainly wraps it to make saving + summarizing convenient.
For PDF inputs, use the `markitdown[pdf]` extra (or the wrapper below, which now does this automatically).

## When to use

Use this skill when you need to:

- pull down a web page as a document-like Markdown representation
- convert binary docs (PDF/DOCX/PPTX) into Markdown for analysis
- quickly produce a short summary of a long document before deeper work

## Quick usage

### Convert a URL or file to Markdown

Run from **this skill folder** (the agent should `cd` here first):

```bash
uvx --from 'markitdown[pdf]' markitdown 
```

To write Markdown to a temp file (prints the path) use the wrapper:

```bash
node to-markdown.mjs  --tmp
```

Tip: when summarizing, the script will **always** write the full converted Markdown to a temp `.md` file and will **always** print a final "Hint" line with the path (so you can open/inspect the full content).

Write Markdown to a specific file:

```bash
uvx --from 'markitdown[pdf]' markitdown  > /tmp/doc.md
```

### Convert + summarize with haiku-4-5 (pass context!)

Summaries are only useful when you provide **what you want extracted** and the **audience/purpose**.

```bash
node to-markdown.mjs  --summary --prompt "Summarize focusing on X, for audience Y. Extract Z."
```

Or:

```bash
node to-markdown.mjs  --summary --prompt "Focus on security implications and action items."
```

This will:

1. convert to Markdown via `uvx --from 'markitdown[pdf]' markitdown`
2. write the full Markdown to a temp `.md` file and print its path as a "Hint" line
3. run `pi --model claude-haiku-4-5` (no-tools, no-session) to summarize using your extra prompt
