feat(marketplace): command consolidation + 8 new plugins (v8.1.0 → v9.0.0) [BREAKING]

Phase 1b: Rename all ~94 commands across 12 plugins to /<noun> <action>
sub-command pattern. Git-flow consolidated from 8→5 commands (commit
variants absorbed into --push/--merge/--sync flags). Dispatch files,
name: frontmatter, and cross-reference updates for all plugins.

Phase 2: Design documents for 8 new plugins in docs/designs/.

Phase 3: Scaffold 8 new plugins — saas-api-platform, saas-db-migrate,
saas-react-platform, saas-test-pilot, data-seed, ops-release-manager,
ops-deploy-pipeline, debug-mcp. Each with plugin.json, commands, agents,
skills, README, and claude-md-integration. Marketplace grows from 12→20.

+
+# /debug-mcp inspect
+
+Deep inspection of an MCP server's configuration, dependencies, and tool definitions.
+
+## Skills to Load
+
+- `skills/visual-header.md`
+- `skills/venv-diagnostics.md`
+- `skills/mcp-protocol.md`
+
+## Agent
+
+Delegate to `agents/mcp-debugger.md`.
+
+## Usage
+
+```
+/debug-mcp inspect <server_name> [--tools] [--deps] [--config]
+```
+
+**Arguments:**
+- `server_name` - Name of the MCP server from .mcp.json
+
+**Options:**
+- `--tools` - List all registered tools with their schemas
+- `--deps` - Show dependency analysis (installed vs required)
+- `--config` - Show configuration files and environment variables
+- (no flags) - Show all sections
+
+## Instructions
+
+Execute `skills/visual-header.md` with context "Server Inspection".
+
+### Phase 1: Configuration
+
+1. Read `.mcp.json` and extract the server definition
+2. Display:
+   - Server name
+   - Command and arguments
+   - Working directory
+   - Environment variable references
+
+```
+## Server: gitea
+
+### Configuration (.mcp.json)
+- Command: /path/to/mcp-servers/gitea/.venv/bin/python
+- Args: ["-m", "mcp_server.server"]
+- CWD: /path/to/mcp-servers/gitea
+- Env file: ~/.config/claude/gitea.env
+```
+
+### Phase 2: Dependencies (--deps)
+
+Apply `skills/venv-diagnostics.md`:
+
+1. Read `requirements.txt` from the server's cwd
+2. Compare with installed packages:
+   ```bash
+   cd <cwd> && .venv/bin/pip freeze
+   ```
+3. Identify:
+   - Missing packages (in requirements but not installed)
+   - Version mismatches (installed version differs from required)
+   - Extra packages (installed but not in requirements)
+
+```
+### Dependencies
+
+| Package | Required | Installed | Status |
+|---------|----------|-----------|--------|
+| mcp | >=1.0.0 | 1.2.3 | OK |
+| httpx | >=0.24 | 0.25.0 | OK |
+| pynetbox | >=7.0 | — | MISSING |
+
+- Missing: 1 package
+- Mismatched: 0 packages
+```
+
+### Phase 3: Tools (--tools)
+
+Parse the server source code to extract tool definitions:
+
+1. Find Python files with `@mcp.tool` decorators or `server.add_tool()` calls
+2. Extract tool name, description, and parameter schema
+3. Group by module/category if applicable
+
+```
+### Tools (42 registered)
+
+#### Issues (6 tools)
+| Tool | Description | Params |
+|------|-------------|--------|
+| list_issues | List issues from repository | state?, labels?, repo? |
+| get_issue | Get specific issue | issue_number (required) |
+| create_issue | Create new issue | title (required), body (required) |
+...
+```
+
+### Phase 4: Environment Configuration (--config)
+
+1. Locate env file referenced in .mcp.json
+2. Read the file (mask secret values)
+3. Check for missing required variables
+
+```
+### Environment Configuration
+
+File: ~/.config/claude/gitea.env
+| Variable | Value | Status |
+|----------|-------|--------|
+| GITEA_API_URL | https://gitea.example.com/api/v1 | OK |
+| GITEA_API_TOKEN | ****...a1b2 | OK |
+
+File: .env (project level)
+| Variable | Value | Status |
+|----------|-------|--------|
+| GITEA_ORG | personal-projects | OK |
+| GITEA_REPO | leo-claude-mktplace | OK |
+```
