SDD Spec Modifier FAQs

Question 1

When should I use sdd-modify instead of sdd-update?

Accepted Answer

Use sdd-modify for heavyweight structural changes, such as adding/removing tasks, updating task descriptions, or applying review feedback. Use sdd-update for lightweight progress tracking, like changing task statuses (e.g., in_progress, completed) or adding journal entries.

Question 2

What safety features does the SDD Spec Modifier provide?

Accepted Answer

It provides three layers of safety: Dry-run previews to visualize changes before they happen, strict schema validation to prevent specification corruption, and automatic backups with rollback support to protect against unintended modification errors.

Question 3

What does the SDD Spec Modifier skill do?

Accepted Answer

The SDD Spec Modifier is a Claude Code capability that systematically applies structural changes, review feedback, and bulk updates to specification files. It ensures project integrity through built-in schema validation, dry-run previews, and automatic rollback support.

Question 4

Can I use this skill to apply changes to multiple tasks at once?

Accepted Answer

Yes, sdd-modify supports bulk modifications. You can provide a JSON file containing multiple operations—such as updating task metadata, adding verification steps, and restructuring phases—and apply them all in a single validated transaction.

Question 5

How does this skill improve my AI coding workflow?

Accepted Answer

It closes the feedback loop between review and implementation. By automatically parsing markdown review reports into structured JSON modifications, it eliminates manual editing errors and ensures that specifications stay in sync with review findings and architectural changes.
