openspec-continue-change

Continue working on a change by creating the next artifact.

Store selection: If the user names a store (a store is a standalone OpenSpec repo registered on this machine) or the work lives in one, run openspec store list --json to discover registered store ids, then pass --store <id> on the commands that read or write specs and changes (new change, status, instructions, list, show, validate, archive, doctor, context). Other commands do not take the flag. Hints printed by commands already carry the flag; keep it on follow-ups. Without a store, commands act on the nearest local openspec/ root.

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

1. If no change name provided, prompt for selection

   Run openspec list --json to get available changes sorted by most recently modified. Then use the AskUserQuestion tool to let the user select which change to work on.

   Present the top 3-4 most recently modified changes as options, showing:

   • Change name
   • Schema (from schema field if present, otherwise "spec-driven")
   • Status (e.g., "0/5 tasks", "complete", "no tasks")
   • How recently it was modified (from lastModified field)

   Mark the most recently modified change as "(Recommended)" since it's likely what the user wants to continue.

   IMPORTANT: Do NOT guess or auto-select a change. Always let the user choose.

2. Check current status

   openspec status --change "<name>" --json
   

   Parse the JSON to understand current state. The response includes:

   • schemaName: The workflow schema being used (e.g., "spec-driven")
   • artifacts: Array of artifacts with their status ("done", "ready", "blocked")
   • isComplete: Boolean indicating if all artifacts are complete
   • planningHome, changeRoot, artifactPaths, and actionContext: path and scope context. Use these instead of assuming repo-local paths.

3. Act based on status:

   ---

   If all artifacts are complete (isComplete: true):

   • Congratulate the user
   • Show final status including the schema used
   • Suggest: "All artifacts created! You can now implement this change or archive it."
   • STOP

   ---

   If artifacts are ready to create (status shows artifacts with status: "ready"):

   • Pick the FIRST artifact with status: "ready" from the status output
   • Get its instructions:

     openspec instructions <artifact-id> --change "<name>" --json
     

   • Parse the JSON. The key fields are:
     • context: Project background (constraints for you - do NOT include in output)
     • rules: Artifact-specific rules (constraints for you - do NOT include in output)
     • template: The structure to use for your output file
     • instruction: Schema-specific guidance
     • resolvedOutputPath: Resolved path or pattern to write the artifact
     • dependencies: Completed artifacts to read for context
   • Create the artifact file:
     • Read any completed dependency files for context
     • Use template as the structure - fill in its sections
     • Apply context and rules as constraints when writing - but do NOT copy them into the file
     • Write to the resolvedOutputPath specified in instructions. If it is a glob pattern, choose the concrete file path using the schema instruction and the change's context
   • Show what was created and what's now unlocked
   • STOP after creating ONE artifact

   ---

   If no artifacts are ready (all blocked):

   • This shouldn't happen with a valid schema
   • Show status and suggest checking for issues

4. After creating an artifact, show progress

   openspec status --change "<name>"
   

Output

After each invocation, show:

• Which artifact was created
• Schema workflow being used
• Current progress (N/M complete)
• What artifacts are now unlocked
• Prompt: "Want to continue? Just ask me to continue or tell me what to do next."
