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"

File	Purpose
`project/CONFIG.yaml`	Stack versions, modules, architecture
`mcp.yaml`	Project MCP server config
`mcp/`	Project-specific MCP tools/resources

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.

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

Define Command Structure (root -> sub -> leaf).
Define Flags (Persistent vs Local).
Handle OS Signals (Graceful Shutdown).

Document Lifecycle

Protocol: 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:

Save final document to project/docs/ path

Change file status from Draft to Approved in header/frontmatter

Update project/docs/ARTIFACT_REGISTRY.md status to ✅ Done

Use notify_user for final approval

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:

Add // TODO(TD-XXX): description in code

Register in project/docs/TECH_DEBT.md

Forbidden: Untracked TODOs, undocumented hardcoded values.

Git Protocol (Hard Stop)

[!CAUTION] Follow ../standards/GIT_PROTOCOL.md.

Branch: Work in feat/<name> or fix/<name>.

Commit: Use Conventional Commits (feat:, fix:).

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.
