Documentation

README

Excerpt

🫡 Implement a plan phase

[!CRITICAL] Implement ONLY ONE phase per invocation. After completing the current phase, STOP and wait for the user to review the changes. Never proceed to the next phase without explicit user approval.

[!CRITICAL] Never commit or push changes automatically. Only suggest commit messages. The user decides when to commit.

🔍 Determining the current phase

The current phase is the first phase in the plan that has at least one unchecked (- [ ]) to-do item. If all phases are fully checked, inform the user that all phases are complete and do not re-implement.

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