Implement tasks from an OpenSpec change. Use when the user wants to start implementing, continue implementation, or work through tasks.
Archive a completed change in the experimental workflow. Use when the user wants to finalize and archive a change after implementation is complete.
Archive multiple completed changes at once. Use when archiving several parallel changes.
Continue working on an OpenSpec change by creating the next artifact. Use when the user wants to progress their change, create the next artifact, or continue their workflow.
Enter explore mode - a thinking partner for exploring ideas, investigating problems, and clarifying requirements. Use when the user wants to think through something before or during a change.
Fast-forward through OpenSpec artifact creation. Use when the user wants to quickly create all artifacts needed for implementation without stepping through each one individually.

Start a new change using the experimental artifact-driven approach.
Input: The user's request should include a change name (kebab-case) OR a description of what they want to build.
Steps
If no clear input provided, ask what they want to build
Use the AskUserQuestion tool (open-ended, no preset options) to ask:
"What change do you want to work on? Describe what you want to build or fix."
From their description, derive a kebab-case name (e.g., "add user authentication" → add-user-auth).
IMPORTANT: Do NOT proceed without understanding what the user wants to build.
Determine the workflow schema
Use the default schema (omit --schema) unless the user explicitly requests a different workflow.
Use a different schema only if the user mentions:
--schema <name>openspec schemas --json and let them chooseOtherwise: Omit --schema to use the default.
Create the change directory
openspec new change "<name>"
Add --schema <name> only if the user requested a specific workflow.
This creates a scaffolded change at openspec/changes/<name>/ with the selected schema.
Show the artifact status
openspec status --change "<name>"
This shows which artifacts need to be created and which are ready (dependencies satisfied).
Get instructions for the first artifact
The first artifact depends on the schema (e.g., proposal for spec-driven).
Check the status output to find the first artifact with status "ready".
openspec instructions <first-artifact-id> --change "<name>"
This outputs the template and context for creating the first artifact.
STOP and wait for user direction
Output
After completing the steps, summarize:
