Milestone Skill

This skill instructs AI agents on how to drive implementation forward incrementally, tracking LOC count, running tests, and creating milestone checkpoints when the 800 LOC threshold is reached without completion.

Skill Purpose

The milestone skill enables AI agents to implement large features step-by-step in manageable increments. It:

• Implements incrementally: Works in chunks of 100-200 LOC per iteration
• Tracks progress: Monitors total LOC count across the session
• Runs tests continuously: Executes tests after each implementation chunk
• Creates checkpoints: Generates milestone documents at 800 LOC threshold
• Signals completion: Returns success when all tests pass

This skill is the core implementation driver used by /issue-to-impl and /miles2miles commands.
