Documentation

README

Excerpt

When this skill is invoked:

Parse the argument for an optional genre/theme hint (e.g., roguelike, space survival, cozy farming). If open or no argument, start from scratch. Also resolve the review mode (once, store for all gate spawns this run):
1. If --review [full|lean|solo] was passed → use that
2. Else read production/review-mode.txt → use that value
3. Else → default to lean
See .claude/docs/director-gates.md for the full check pattern.
Check for existing concept work:
- Read design/gdd/game-concept.md if it exists (resume, don't restart)
- Read design/gdd/game-pillars.md if it exists (build on established pillars)

This is the opening of the README. Read the full README on GitHub.
