Description

Goal

Component to split Markdown/semantic text into offset chunks for chunked retrieval (RAG). Might use headings/paragraphs as boundaries or basic token counts with overlaps.

Scope/Features

  • Input: string
  • Output: structured array of chunks (text, offset/indices)
  • Configurable: chunk size, overlap, min paragraph, etc.

Rough WIT shape

  • split(input: string, params: chunk_params) -> list<chunk>
  • Chunk struct: {text, start, end, ...}

Labels

  • good first issue

Contributor guide

Research direction
Study the existing WIT definitions and component implementations in the repository. Understand the chunker requirements: configurable chunk size, overlap, and handling of Markdown boundaries. Implement the split function in Rust, test it, and ensure it fits the component model. Document the parameters and output format.
