# Text Summarizer Skill

## Required Environment Variables

- None required.

## Invocation Contract

- Call `run_skill_script` with:
  - `skill_name`: `text-summarizer`
  - `script_name`: `summarize`
- This script requires one input source, passed as `--file` or `--text`.
- Pass those options in `kwargs`.

## Script API

- required input (exactly one):
  - `file`: path to text file, or
  - `text`: inline text to summarize
- optional `kwargs`:
  - `max_sentences`: integer
  - `method`: `extractive | key_points`

## `run_skill_script` Examples

  "kwargs": {
    "file": "document.txt",
    "max_sentences": 5,
    "method": "extractive"
  }

    "method": "key_points",
    "max_sentences": 3
  }
}
