Workflow Visualization Command

[crashfrog]

Parent

Part of generalized allelic typing system design (discussed in conversation 2026-05-22)

What to build

Add torchbase workflow inspect <strategy|torch-path> command that renders workflow pipeline as ASCII box diagram. Shows task flow, conditionals, and key parameters.

Works for:

• Built-in workflows: torchbase workflow inspect balanced
• Torch-embedded workflows: torchbase workflow inspect path/to/torch/

Rendering:

• Parse WDL using miniwdl or similar library
• Generate ASCII diagram with boxes for tasks
• Show conditional branches with ├──[condition]──┐ notation
• Include task names + key parameters by default
• Add --verbose flag for full parameter details

Surface WDL parsing errors but don't validate workflow correctness.

Acceptance criteria

• torchbase workflow inspect command exists
• Accepts built-in strategy names (fast/balanced/sensitive)
• Accepts torch directory paths
• Renders ASCII box diagram of pipeline
• Shows conditional branches clearly
• Includes task names and key parameters
• --verbose flag shows full details
• Surfaces parsing errors from WDL library
• Tests verify diagram generation for all three built-in workflows

Completed in PR #77 - implemented workflow inspect command with WDL parser, ASCII diagram renderer, and import validation. Supports built-in strategies and torch-embedded workflows with verbose mode.
