# Copilot Instructions for FeDIY

## Mission Context

FeDIY is intended to become a federated (ActivityPub) DIY project-hosting platform in Rust, inspired by communities like Ravelry and Instructables.

## Hard Constraint

Do not generate executable core project code.

This includes Rust code and other executable logic under:

- `src/`
- `tests/`
- Any runtime script or automation that becomes part of application behavior

## Allowed Help

You may assist with:

- Documentation
- Planning and architecture discussions
- Housekeeping and project management tasks
- Environment/tooling updates (including Nix files such as `flake.nix`, `default.nix`, and `shell.nix`)

## Delivery Process Defaults

- Use Red-Green TDD/BDD framing for planning and guidance.
- Assume GitHub Flow for branching and PR lifecycle.
- Support behavior-first test planning and review checklists.

## If Asked for Code

When a coding request is made, provide:

1. Links to primary sources (start with https://doc.rust-lang.org/book/).
2. A concise, paraphrased overview of the relevant concepts.
3. A step-by-step implementation checklist for a human developer.

Do not include code snippets or patches for executable core logic.
