Propose a new change - create the change and generate all artifacts in one step.
I'll create a change with artifacts:
- proposal.md (what & why)
- design.md (how)
- tasks.md (implementation steps)
When ready to implement, run /opsx:apply
Input: The user's request should include a change name (kebab-case), a description of what they want to build, OR an epic name plus a candidate change to propose.
Steps
-
If an epic is provided, resolve the change from the epic first
- Read
openspec/epics/<epic-name>/epic.md
- Find the
Candidate Changes section
- If the user already named a candidate change, use it
- If there is only one strong candidate, use it
- If there are multiple viable candidate changes, ask the user to choose one
Derive the change name from the chosen candidate if needed.
Before finishing, update the chosen candidate row in the epic ledger to reflect:
Status: proposed
Linked Change: openspec/changes/<name>
- any brief note that helps future follow-up
IMPORTANT: When working from an epic, keep the resulting change scoped to a single candidate change, not the whole epic.
-
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.
-
Create the change directory
openspec new change "<name>"
This creates a scaffolded change at openspec/changes/<name>/ with .openspec.yaml.
-
Get the artifact build order
openspec status --change "<name>" --json
Parse the JSON to get:
applyRequires: array of artifact IDs needed before implementation (e.g., ["tasks"])
artifacts: list of all artifacts with their status and dependencies
-
Create artifacts in sequence until apply-ready
Use the TodoWrite tool to track progress through the artifacts.
Loop through artifacts in dependency order (artifacts with no pending dependencies first):
a. For each artifact that is ready (dependencies satisfied):
b. Continue until all applyRequires artifacts are complete
- After creating each artifact, re-run
openspec status --change "<name>" --json
- Check if every artifact ID in
applyRequires has status: "done" in the artifacts array
- Stop when all
applyRequires artifacts are done
c. If an artifact requires user input (unclear context):
- Use AskUserQuestion tool to clarify
- Then continue with creation
-
Show final status
openspec status --change "<name>"
Output
After completing all artifacts, summarize:
- Epic used (if any)
- Change name and location
- List of artifacts created with brief descriptions
- What's ready: "All artifacts created! Ready for implementation."
- Prompt: "Run
/opsx:apply or ask me to implement to start working on the tasks."
Artifact Creation Guidelines
- Follow the
instruction field from openspec instructions for each artifact type
- The schema defines what each artifact should contain - follow it
- Read dependency artifacts for context before creating new ones
- Use
template as the structure for your output file - fill in its sections
- IMPORTANT:
context and rules are constraints for YOU, not content for the file
- Do NOT copy
<context>, <rules>, <project_context> blocks into the artifact
- These guide what you write, but should never appear in the output
Guardrails
- When an epic is provided, always read the epic before drafting artifacts
- Treat the epic as planning context and the candidate change as the implementation unit
- When an epic is provided, update its candidate change ledger so future sessions can see progress
- Create ALL artifacts needed for implementation (as defined by schema's
apply.requires)
- Always read dependency artifacts before creating a new one
- If context is critically unclear, ask the user - but prefer making reasonable decisions to keep momentum
- If a change with that name already exists, ask if user wants to continue it or create a new one
- Verify each artifact file exists after writing before proceeding to next
