Implement tasks from an OpenSpec change. Use when the user wants to start implementing, continue implementation, or work through tasks.
Implement tasks from an OpenSpec change.
When operating in this repository, follow these core principles for AI interaction:
Input: Optionally specify a change name. If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
Steps
Select the change
If a name is provided, use it. Otherwise:
openspec list --json to get available changes and use the AskUserQuestion tool to let the user selectAlways announce: "Using change: <name>" and how to override (e.g., /opsx:apply <other>).
Check status to understand the schema
openspec status --change "<name>" --json
Parse the JSON to understand:
schemaName: The workflow being used (e.g., "spec-driven")Get apply instructions
openspec instructions apply --change "<name>" --json
This returns:
Handle states:
state: "blocked" (missing artifacts): show message, suggest using openspec-continue-changestate: "all_done": congratulate, suggest archiveRead context files
Read the files listed in contextFiles from the apply instructions output.
The files depend on the schema being used:
