# ByteLyst Ecosystem — Reusable AI Prompts

> **Location:** `AI.dev/PROMPTS/`
> **Audience:** Claude Code, Codex, Cursor, Copilot, Windsurf Cascade, Gemini, and any AI coding agent.
> **Scope:** All 37 repos in `D:\BYTELYST\CODE\` — common platform, product repos, tooling repos.

## How to Use

Copy-paste a prompt into your AI assistant, or reference it by path:

```
@file AI.dev/PROMPTS/roadmap-execution.md
```

Each prompt is **self-contained** — it includes the context the agent needs without
requiring you to manually explain the ecosystem every time.

## Conventions

- **Agent-agnostic:** Prompts work across Claude, Copilot, Cursor, Windsurf, Gemini.
- **Ecosystem-aware:** Each prompt embeds the key ByteLyst conventions (productId, Fastify module pattern, @bytelyst/* packages, pnpm workspace).
- **Commit-friendly:** Prompts that produce code changes include commit message guidance.
- **Incremental:** Each prompt favors small, validated, committed steps over big-bang changes.

## Adding a New Prompt

1. Create `AI.dev/PROMPTS/<prompt-name>.md`
2. Include a YAML-style header with `name`, `description`, `argument-hint`
3. Add it to this index
4. Commit: `docs(prompts): add <prompt-name> reusable prompt`
