Dependency Mapping
Generate Mermaid flowcharts that visualize GitHub issue dependencies, blocking relationships, and critical paths through your project. This skill parses issue descriptions and labels for dependency keywords, builds a relationship map, and produces clear diagrams with phases and critical path highlighting.

How to use it⌗
Use this skill when:
- You want to see which issues block others
- Mapping issue dependencies or visualizing blocking chains
- During sprint planning to identify the critical path
- After issue decomposition to visualize relationships
Features⌗
Automatic dependency detection Parses issue bodies and labels for dependency keywords like “blocked by,” “depends on,” “after,” and “prerequisite” to build the relationship map.
Critical path highlighting Identifies the longest chain of dependencies and highlights it with thick arrows and color styling to show what determines minimum project duration.
Phased subgraph organization Groups issues into logical phases using Mermaid subgraphs for clear visual separation of foundation, feature, and integration work.
Multiple graph layouts Supports linear dependencies (left-to-right), parallel work (top-to-bottom), and complex multi-branch layouts with consistent issue node naming conventions.
Requires the gh CLI (or an equivalent GitHub MCP server) to gather issue data.
