## TASK-001 - Create Python CLI project skeleton
Status: Done

Goal: Create the initial package structure, CLI entry point, and markdown-first bootstrap.

Acceptance Criteria:
- `rdb --help` runs
- `rdb init` creates project files
- README exists

## TASK-002 - Run initial project discovery
Status: Todo

Goal: Run `rdb discover` and capture the core project answers.

Acceptance Criteria:
- all 10 core questions are answered
- discovery-log.md contains ledger entries
- low-confidence answers are marked for follow-up

## TASK-003 - Review generated context files
Status: Todo

Goal: Review the generated markdown files and fill in obvious gaps.

Acceptance Criteria:
- product-brief.md reviewed
- architecture.md reviewed
- open-questions.md updated

## TASK-004 - Implement ask-more command
Status: Todo

Goal: Add a command that finds weak answers and asks deeper follow-up questions.

Acceptance Criteria:
- command reads discovery-log.md
- low-confidence answers are detected
- follow-up answers are appended to discovery-log.md
