Does it integrate with CLI tools?

Yes, it utilizes the 'openspec' CLI for listing active changes, validating specifications with strict checks, and archiving completed work.

What is a Spec Delta?

Spec Deltas are granular change markers used to track whether requirements are ADDED, MODIFIED, REMOVED, or RENAMED within your project specifications.

What is the 7-stage pipeline in OpenSpec?

The pipeline consists of Discovery (scope), Planning (Change ID), Specification (Deltas), Design (Technical decisions), Implementation (Tasks), Verification (Testing), and Archive (Cleanup).

When can I skip the proposal process?

Proposals can be skipped for minor bug fixes, typo corrections, non-breaking dependency updates, configuration changes, or adding tests to existing behavior.

How does this skill handle task tracking?

It manages a tasks.md file using a specific parsing format that supports Phases, Sections, and sub-tasks with 2-space indentation for clear progress visualization.

Productivity & Workflow

Manages the full Spec-Driven Development (SDD) lifecycle through a structured 7-stage pipeline and automated documentation.

The OpenSpec skill implements a rigorous Spec-Driven Development (SDD) workflow within Claude Code, guiding developers through a standardized process from initial discovery to final archival. It automates the generation of proposals, manages hierarchical task checklists in Markdown, and tracks granular specification changes (Deltas) to ensure every code change is intentional, documented, and validated. This skill is perfect for teams and solo developers who prioritize architectural integrity and require a clear audit trail for complex software projects.
