- Name the file
- Read the source
- Explain the project
Turn a named project file into an explanation you can check against the source.
Keep project-specific instructions in a reusable agent instead of repeating them in every conversation.
The outcome
Section titled “The outcome”Input: A project file and a question.
Output: An explanation with file references.
Run the starting example
Section titled “Run the starting example”Follow the file-tool tutorial. Its complete bundle
contains reader.chatmd and the fictional Lantern project reference. Ask the
agent to explain that file and identify information the file does not contain.
Adapt it to a real repository
Section titled “Adapt it to a real repository”Replace the sample with a file you are authorized to share with the configured provider. Keep questions concrete and ask for file references. Add directory listing when the agent needs to discover files; add indexed retrieval when reading named files is no longer enough.
The bundled example reads one reference file. It does not automatically map an entire repository. The tools guide explains additional capabilities, and search and indexing explains Markdown retrieval and OCaml-specific code indexing.
