name: "OPSX: Apply" description: Implement tasks from an OpenSpec change (Experimental) category: Workflow
Implement tasks from an OpenSpec change.
Input: Optionally specify a change name (e.g., /opsx:apply add-auth). If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
Steps
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: " 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")planningHome, changeRoot, and actionContext: planning scope and edit constraintsGet apply instructions
openspec instructions apply --change "<name>" --json
This returns:
contextFiles: artifact ID -> array of concrete file paths (varies by schema)Handle states:
state: "blocked" (missing artifacts): show message, suggest using /opsx:continuestate: "all_done": congratulate, suggest archiveWorkspace guard: If status JSON reports actionContext.mode: "workspace-planning" and allowedEditRoots is empty, explain that full workspace apply is not supported in this slice. Treat linked repos and folders as read-only context, ask the user to select an affected area through an explicit implementation workflow, and STOP before editing files.
Read every file path listed under contextFiles from the apply instructions output.
The files depend on the schema being used:

Output During Implementation
## Implementing: <change-name> (schema: <schema-name>)
Working on task 3/7: <task description>
[...implementation happening...]
✓ Task complete
Working on task 4/7: <task description>

✓ Task complete
Output On Completion
## Implementation Complete
**Change:** <change-name>
**Schema:** <schema-name>
**Progress:** 7/7 tasks complete ✓
