SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? It removes the guesswork of turning an OpenSpec change proposal into working code by reading the change's tasks, context files, and status directly from the openspec CLI and guiding implementation task by task. ## Core Features & Use Cases - Change Selection: Infers the target change from conversation context or lists available changes via openspec list --json when ambiguous. - Status-Aware Implementation: Parses openspec status and openspec instructions apply output to understand the schema, progress, and remaining tasks before writing code. - Task Loop with Guardrails: Implements each pending task, marks checkboxes complete in the tasks file, and pauses on ambiguity, design issues, or errors instead of guessing. - Use Case: You have an approved OpenSpec change with a tasks file. Invoke this skill to work through all remaining tasks, updating checkboxes as each one is completed, until the change is ready to archive. ## Quick Start Ask the assistant to start implementing the tasks for your current OpenSpec change, optionally naming the change explicitly.

FAQPage Schema
How do I implement tasks from an OpenSpec change?

Invoke the apply workflow with an optional change name. It runs openspec status and openspec instructions apply to load context files and the task list, then implements each pending task and marks its checkbox complete.

What happens if I don't specify a change name?

The skill infers the change from conversation context or auto-selects when only one active change exists. If ambiguous, it runs openspec list --json and asks you to pick from the available changes.

Does openspec-apply-change require the openspec CLI?

Yes, the openspec CLI is a hard requirement. The skill depends on commands like openspec status, openspec instructions apply, and openspec list to discover schemas, context files, and task progress.

What happens when a task is unclear or implementation hits an error?

The skill pauses instead of guessing. It reports the issue, shows current progress, and presents options such as clarifying the requirement or updating the change's artifacts before continuing.

Can I apply a change before all its artifacts are complete?

Yes, the workflow is fluid and can be invoked anytime tasks exist. If required artifacts are missing, the status shows a blocked state and suggests continuing artifact creation first.
