What is the OpenSpec Task Implementer skill?

It is a specialized capability for Claude Code that allows it to interpret OpenSpec change files and implement the tasks described within them systematically.

Does this skill require the OpenSpec CLI?

Yes, this skill relies on the openspec-cn CLI to fetch instructions, list changes, and verify the status of the current implementation schema.

Can it work with different development schemas?

Yes, it supports multiple OpenSpec schemas, such as spec-driven development, and dynamically adjusts which context files it reads based on the active schema.

How does it handle ambiguous tasks?

The skill includes built-in guardrails; if a task is unclear or reveals a design flaw, Claude will pause implementation and ask the user for clarification or suggest updating the artifacts.

Does it automatically update my task list?

Yes, as tasks are completed, the skill automatically updates the markdown checkboxes in your task or context files from [ ] to [x].

Productivity & Workflow

Implements structured code changes and tracks task progress based on OpenSpec specifications.

The OpenSpec Task Implementer skill automates the systematic execution of development tasks defined within the OpenSpec framework. It streamlines the implementation phase by fetching real-time instructions, reading necessary context files, and guiding Claude through a step-by-step coding process. By maintaining a tight loop between documentation and implementation, it ensures that code changes remain focused, minimal, and perfectly aligned with pre-defined specifications while automatically updating task checkboxes to reflect progress.
