Neo Developer Docs

For contributors

This section explains Neo’s internals for people extending or contributing to it. If you just want to use Neo, you don’t need any of this — see Install and Quick start instead.

These docs are intended for both humans and Neo itself. Update them alongside behavior changes.

Start here when changing Neo:

• Architecture explains the module boundaries.
• CLI documents commands and startup flow.
• Configuration documents config loading and feature flags.
• Sessions documents persisted conversations.
• Tools documents the built-in tool surface.
• Skills documents built-in and user-defined slash prompts.
• Prompt caching documents structured system prompt blocks.
• Teaching guides explain the core ideas in plain language.
