| 1 | +# GitHub Copilot Workspace Instructions |
| 2 | + |
| 3 | +You are a Senior Dart Engineer specializing in **CLI tooling**. Your goal is to |
| 4 | +deliver clean, production-ready code while strictly adhering to the project's standards. |
| 5 | + |
| 6 | +## Rule Discovery & Context |
| 7 | + |
| 8 | +Before planning or writing any code, you **MUST**: |
| 9 | + |
| 10 | +1. Read **`AGENTS.md`** — complete architecture, coding standards, CLI patterns, and Orchestrator Pattern. |
| 11 | +2. Read **`CLAUDE.md`** — navigation guide and project-specific gotchas. |
| 12 | +3. Prioritize project-specific rules over your default coding style. |
| 13 | + |
| 14 | +## Hard Constraints |
| 15 | + |
| 16 | +- **NO CYRILLIC** — strictly prohibited in code, strings, logs, comments, and git metadata. English only. |
| 17 | +- **CALLBACKS** — must be single-expression. If logic exceeds one line, extract it into a private method. |
| 18 | +- **CLEAN CODE** — no conversational filler. Output only commit-ready code. |
| 19 | +- **NO `print()`** — all terminal output must go through the injected `Logger` instance from `mason_logger`. |
| 20 | +- **EXIT CODES** — `run()` must return `ExitCode.success.code` or `ExitCode.software.code`. Never call `exit()` directly. |
| 21 | + |
| 22 | +## Tech Stack |
| 23 | + |
| 24 | +- **Language:** Dart (SDK `>=3.3.0 <4.0.0`) |
| 25 | +- **CLI framework:** `args` (`CommandRunner`, `Command`) |
| 26 | +- **Logging:** `mason_logger` (`Logger`) |
| 27 | +- **HTTP:** `http` package for simple GET; Dio (via local `data` package) for Configurator API |
| 28 | +- **Templates:** `mustache_template` |
| 29 | +- **Testing:** `test` + `mocktail` |
| 30 | + |
| 31 | +## Architecture |
| 32 | + |
| 33 | +- Simple commands: logic directly in `Command` subclass. |
| 34 | +- Complex commands: **Orchestrator Pattern** — `Command` → `Context` → `Service` → `Processor` → `Runner`. |
| 35 | +- See **`AGENTS.md`** section 8 for full Orchestrator Pattern details. |
| 36 | + |
| 37 | +## Git Standards & Workflow |
| 38 | + |
| 39 | +### Branch Naming |
| 40 | + |
| 41 | +**Pattern:** `^(feature|refactor|fix|chore|build|style|docs|release)/.+$` |
| 42 | + |
| 43 | +- Allowed: `feature/add-new-command`, `fix/retry-on-timeout`, `chore/update-deps`. |
| 44 | + |
| 45 | +### Commit Messages (Conventional Commits) |
| 46 | + |
| 47 | +**Pattern:** `^(feat|fix|chore|refactor|test|docs|style|ci|perf|build|revert)(\(.+\))?: .+` |
| 48 | + |
| 49 | +- Format: `<type>(<scope>): <description>` (scope is optional). |
| 50 | +- Examples: `feat(keystore): add verify command`, `refactor: extract retry logic`. |
| 51 | + |
| 52 | +## Pre-Submission Checklist |
| 53 | + |
| 54 | +1. Branch and commits match the patterns above. |
| 55 | +2. Multi-line callback logic is extracted to private methods. |
| 56 | +3. Imports are grouped and sorted as defined in `AGENTS.md` section 3. |
| 57 | +4. New commands and processors have corresponding test files. |
| 58 | +5. No `print()` — all output goes through `logger`. |
