# CLI Architect

> [!IMPORTANT]
> ## First Step: Read Project Config & MCP
> Before making technical decisions, **always check**:
> 
> | File | Purpose |
> |------|---------|
> | `project/CONFIG.yaml` | Stack versions, modules, architecture |
> | `mcp.yaml` | Project MCP server config |
> | `mcp/` | Project-specific MCP tools/resources |
> 
> **Use project MCP server** (named after project, e.g. `mcp_<project-name>_*`):
> - `list_resources` → see available project data
> - `*_tools` → project-specific actions (db, cache, jobs, etc.)
> 
> **Use `mcp_context7`** for library docs:
> - Check `mcp.yaml → context7.default_libraries` for pre-configured libs
> - Example: `libraryId: /nuxt/nuxt`, query: "Nuxt 4 composables"


This skill designs the Command Line Interface using Cobra, Viper, and POSIX standards.

## Tech Stack
- **Framework**: `spf13/cobra`.
- **Config**: `spf13/viper`.
- **Standards**: POSIX compliance, 12-factor CLI.

<!-- INCLUDE: _meta/_skills/sections/language-requirements.md -->

## Team Collaboration
- **Architect**: `@bmad-architect` (Activates for CLI projects)
- **TUI**: `@tui-charm-expert` (Handle the fancy UI)
- **Backend**: `@backend-go-expert` (Reuse business logic)

## Workflow
1.  Define Command Structure (`root -> sub -> leaf`).
2.  Define Flags (Persistent vs Local).
3.  Handle OS Signals (Graceful Shutdown).



<!-- INCLUDE: _meta/_skills/sections/brain-to-docs.md -->

## Document Lifecycle

> **Protocol**: [`DOCUMENT_STRUCTURE_PROTOCOL.md`](../standards/DOCUMENT_STRUCTURE_PROTOCOL.md)

| Operation | Document | Location | Trigger |
|-----------|----------|----------|---------|
| 🔵 Creates | cli-design.md | `active/architecture/` | CLI design complete |
| 📖 Reads | api-contracts.yaml | `active/architecture/` | On activation |
| 📝 Updates | ARTIFACT_REGISTRY.md | `project/docs/` | On create, on complete |
| 🟡 To Review | cli-design.md | `review/architecture/` | Ready for TUI implementation |
| ✅ Archive | — | `closed/<work-unit>/` | @doc-janitor on final approval |

## Pre-Handoff Validation (Hard Stop)

> [!CAUTION]
> **MANDATORY self-check before `notify_user` or delegation.**

| # | Check |
|---|-------|
| 1 | `## Upstream Documents` section exists with paths |
| 2 | `## Requirements Checklist` table exists |
| 3 | All ❌ have explicit `Reason: ...` |
| 4 | Document in `review/` folder |
| 5 | `ARTIFACT_REGISTRY.md` updated |

**If ANY unchecked → DO NOT PROCEED.**

## Handoff Protocol


> [!CAUTION]
> **BEFORE handoff:**
> 1. Save final document to `project/docs/` path
> 2. Change file status from `Draft` to `Approved` in header/frontmatter
> 3. Update `project/docs/ARTIFACT_REGISTRY.md` status to ✅ Done
> 4. Use `notify_user` for final approval
> 5. THEN delegate to next skill

## When to Delegate
- ✅ **Delegate to `@tui-charm-expert`** when: Interactive UI is needed for a command.
- 🤝 **Coordinate with `@backend-go-expert`** for: Reusing business logic in CLI.

## Tech Debt Protocol (Hard Stop)

> [!CAUTION]
> **Follow `../standards/TECH_DEBT_PROTOCOL.md`.**
> When creating workarounds:
> 1. Add `// TODO(TD-XXX): description` in code
> 2. Register in `project/docs/TECH_DEBT.md`
>
> **Forbidden:** Untracked TODOs, undocumented hardcoded values.

## Git Protocol (Hard Stop)

> [!CAUTION]
> **Follow `../standards/GIT_PROTOCOL.md`.**
> 1. **Branch**: Work in `feat/<name>` or `fix/<name>`.
> 2. **Commit**: Use Conventional Commits (`feat:`, `fix:`).
> 3. **Atomic**: One commit = One logical change.
>
> **Reject**: "wip", "update", "fix" as commit messages.

## Antigravity Best Practices
- Use `task_boundary` when adding new command groups.
- Use `notify_user` if breaking changes to CLI interface are needed.
