Ladder Init

Bootstrap .ladder/ directory structure with OVERVIEW.md and progress.md.

When to Use

• User says "ladder init," "initialize ladder," "set up specs," "bootstrap phases," or "/ladder-init"
• Starting phased spec-driven development on a new or existing project
• Run once per project

When NOT to Use

• .ladder/OVERVIEW.md already exists → will exit gracefully (idempotency gate)
• User wants to create a phase spec → use /ladder-create
• User wants to fix a malformed spec → use /ladder-refine
• User wants to implement a phase → use /ladder-execute
