lmiranda 2e65b60725 refactor(projman): extract skills and consolidate commands
Major refactoring of projman plugin architecture:

Skills Extraction (17 new files):
- Extracted reusable knowledge from commands and agents into skills/
- branch-security, dependency-management, git-workflow, input-detection
- issue-conventions, lessons-learned, mcp-tools-reference, planning-workflow
- progress-tracking, repo-validation, review-checklist, runaway-detection
- setup-workflows, sprint-approval, task-sizing, test-standards, wiki-conventions

Command Consolidation (17 → 12 commands):
- /setup: consolidates initial-setup, project-init, project-sync (--full/--quick/--sync)
- /debug: consolidates debug-report, debug-review (report/review modes)
- /test: consolidates test-check, test-gen (run/gen modes)
- /sprint-status: absorbs sprint-diagram via --diagram flag

Architecture Cleanup:
- Remove plugin-level mcp-servers/ symlinks (6 plugins)
- Remove plugin README.md files (12 files, ~2000 lines)
- Update all documentation to reflect new command structure
- Fix documentation drift in CONFIGURATION.md, COMMANDS-CHEATSHEET.md

Commands are now thin dispatchers (~20-50 lines) that reference skills.
Agents reference skills for domain knowledge instead of inline content.

viz-platform MCP Server

Model Context Protocol (MCP) server for Dash Mantine Components validation and visualization tools.

Overview

This MCP server provides 21 tools for:

  • DMC Validation: Version-locked component registry prevents Claude from hallucinating invalid props
  • Chart Creation: Plotly-based visualization with theme integration
  • Layout Composition: Dashboard layouts with responsive grids
  • Theme Management: Design token-based theming system
  • Page Structure: Multi-page Dash app generation

Tools

DMC Tools (3)

Tool Description
list_components List available DMC components by category
get_component_props Get valid props, types, and defaults for a component
validate_component Validate component definition before use

Chart Tools (2)

Tool Description
chart_create Create Plotly chart (line, bar, scatter, pie, histogram, area, heatmap)
chart_configure_interaction Configure chart interactions (zoom, pan, hover)

Layout Tools (5)

Tool Description
layout_create Create dashboard layout structure
layout_add_filter Add filter components to layout
layout_set_grid Configure responsive grid settings
layout_get Retrieve layout configuration
layout_add_section Add sections to layout

Theme Tools (6)

Tool Description
theme_create Create new theme with design tokens
theme_extend Extend existing theme with overrides
theme_validate Validate theme completeness
theme_export_css Export theme as CSS custom properties
theme_list List available themes
theme_activate Set active theme for visualizations

Page Tools (5)

Tool Description
page_create Create new page structure
page_add_navbar Add navigation bar to page
page_set_auth Configure page authentication
page_list List available pages
page_get_app_config Get full app configuration

Configuration

Environment Variables

Variable Required Description
DMC_VERSION No Dash Mantine Components version (auto-detected if installed)
VIZ_DEFAULT_THEME No Default theme name
CLAUDE_PROJECT_DIR No Project directory for theme storage

Theme Storage

Themes can be stored at two levels:

  • User-level: ~/.config/claude/themes/
  • Project-level: {project}/.viz-platform/themes/

Project-level themes take precedence.

Component Registry

The server uses a static JSON registry for DMC component validation:

  • Pre-generated from DMC source code
  • Version-tagged (e.g., dmc_2_5.json)
  • Prevents hallucination of non-existent props
  • Fast, deterministic validation

Registry files are stored in registry/ directory.

Tests

94 tests with coverage:

  • test_config.py: 82% coverage
  • test_component_registry.py: 92% coverage
  • test_dmc_tools.py: 88% coverage
  • test_chart_tools.py: 68% coverage
  • test_theme_tools.py: 99% coverage

Run tests:

cd mcp-servers/viz-platform
source .venv/bin/activate
pytest tests/ -v

Dependencies

  • Python 3.10+
  • FastMCP
  • plotly
  • dash-mantine-components (optional, for version detection)

Usage

This MCP server is used by the viz-platform plugin. See the plugin's commands in plugins/viz-platform/commands/ for usage.
