Sort Tasks

Topological Task Sorter

Sort task files by their dependencies to determine optimal execution order. Detects circular dependencies and validates dependency references.

Usage

/sort-tasks                              # Sort tasks in current phase
/sort-tasks <path>                       # Sort tasks in specific path
/sort-tasks --json                       # JSON output (for programmatic use)
/sort-tasks --markdown                   # Markdown table (for documentation)

Arguments

• $1 - Path to phase folder (default: specification)
• --json - Output as JSON
• --markdown - Output as Markdown table

Process

Step 1: Run the Sort Script

Execute the topological sort script:

node .claude/scripts/sort-tasks.mjs "<path>" [--json|--markdown]

Step 2: Present Results

For human-readable output (default):

• Show numbered list of tasks in execution order
• Highlight entry points (tasks with no dependencies)
• Report any circular dependencies as errors
• Show warnings for missing dependency references

For markdown output (--markdown):

• Generate a table suitable for inclusion in documentation
• Include Order, Task ID, Name, and Dependencies columns

For JSON output (--json):

• Return structured data for programmatic use

Output Format

Human-Readable (Default)

✅ Topological order (N tasks):

1. task-01 - Solution Setup
2. task-02 - Shared Kernel (depends on: task-01)
3. task-03 - Contracts (depends on: task-01)
4. task-04 - Common (depends on: task-02)

⚡ Entry points (no dependencies): task-01

❌ Circular dependencies detected: task-05, task-06  (if any)
⚠️ Warnings:
   - Task "task-07" references unknown dependency "task-99"

Markdown Table

## Execution Order (Topological Sort)

| Order | Task ID | Name | Dependencies |
|-------|---------|------|--------------|
| 1 | task-01 | Solution Setup | - |
| 2 | task-02 | Shared Kernel | task-01 |
...

Error Handling

• No tasks found: Report that no task files were found in the specified path
• Circular dependencies: List all tasks involved in cycles, exit with error
• Missing dependencies: Warn about referenced but non-existent task IDs

Integration with dotnet-tech-lead

This skill is automatically called by the dotnet-tech-lead agent after:

1. Creating new task files
2. Modifying task dependencies
3. User requests re-sorting

The markdown output is included in the task summary presented to the user.

Safety Rules

1. This is a read-only operation - no files are modified
2. Only reads task metadata from markdown files
3. Safe to run at any time without side effects
