# spk-doctrine-spdd-reasons

Use this skill when a mission opts into SPDD, REASONS Canvas work, or structured
prompt rationale review.

## Flow

1. Confirm SPDD is selected by charter or mission context.
2. Author or review the REASONS Canvas before downstream prompts depend on it.
3. Keep rationale tied to mission decisions, not generic process commentary.
4. Return approved rationale to specify, plan, or implementation steps.

## Legacy Alias

For detailed REASONS workflow, use `spec-kitty-spdd-reasons` when available.
