Openspec Propose

Propose a new change - create the change and generate all artifacts in one step.

I'll create a change with the artifacts your schema defines. With the default spec-driven schema that is:

• proposal.md (what & why)
• specs/<capability>/spec.md (what the system must do - a delta, not the main spec)
• design.md (how)
• tasks.md (implementation steps)

When ready to implement, run /opsx-apply

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, view). 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: The user's request should include a change name (kebab-case) OR a description of what they want to build.

Steps

1. If no clear input provided, ask what they want to build

   Ask the user (open-ended, no preset options):

   "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.

2. Create the change directory

   openspec new change "<name>"
   

   This creates a scaffolded change in the planning home resolved by the CLI with .openspec.yaml.

3. 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, each with its status and its requires edges (the artifact IDs it directly depends on)
   • planningHome, changeRoot, artifactPaths, and actionContext: path and scope context. Use these instead of assuming repo-local paths.

4. Create every artifact in the required set

   Use a todo list 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):

   • Get instructions:

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

   • The instructions JSON includes:
     • 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 for this artifact type
     • skipped/warning: present when the change declares skip_specs and this artifact must NOT be created - stop and pick another artifact
     • resolvedOutputPath: Resolved path or pattern to write the artifact
     • dependencies: Completed artifacts to read for context
   • Read any completed dependency files for context - always re-read them from disk, even if you saw them earlier in the conversation (the user may have edited them)
   • If the instruction field delegates creation to a specific skill or command, invoke it to produce the artifact instead of writing the file yourself, then verify the artifact file exists at resolvedOutputPath
   • Otherwise create the artifact file using template as the structure and write it to resolvedOutputPath. If resolvedOutputPath is a glob, follow instruction to choose the concrete file path
   • Apply context and rules as constraints - but do NOT copy them into the file
   • Show brief progress: "Created "

   b. Continue until every artifact in the required set exists (not just apply.requires)

   • After creating each artifact, re-run openspec status --change "<name>" --json
   • The required set is applyRequires plus every artifact reachable from those by following the requires edges in status --json - walk them transitively (spec-driven closes over proposal, specs, design, tasks). Leave artifacts outside that set alone
   • status is file-existence only, so an applyRequires artifact reading done does NOT mean its dependencies exist - writing tasks.md early marks tasks done while specs was never written. Use each artifact's requires edges, not its status, to build the required set: a done artifact still lists what it depends on
   • An artifact already reading status: "skipped" is satisfied: the change declares skip_specs in .openspec.yaml, so its files must NOT exist. Never try to create one
   • Create every artifact in the required set that is missing, then re-check - creating one can unblock others
   • Skip one only when status already reports it skipped, or when its own instruction says it is conditional: run openspec instructions <artifact-id> --change "<name>" --json and skip only if its instruction field marks it optional (e.g. "create only if..."). Spec-driven's design.md qualifies; specs qualifies only via the skipped status above, never by your own judgment. Tell the user, and do not reconsider it
   • Dependencies are enablers, not gates: if a required artifact is still blocked only because you skipped a conditional dependency, write it anyway
   • Stop when every artifact in the required set is done, skipped, or was deliberately skipped

   c. If an artifact requires user input (unclear context):

   • Ask the user to clarify
   • Then continue with creation

5. Show final status

   openspec status --change "<name>"
   

Output

After completing all artifacts, summarize:

• Change name and location
• List of artifacts created with brief descriptions, plus any conditional artifact you skipped and why
• What's ready: "All artifacts needed for implementation are ready."
• 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 - it is the authoritative guidance, even for familiar artifact names
• If the instruction field directs you to use a specific skill or command to create the artifact, invoke it instead of writing the artifact directly
• 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

• Create every artifact the apply phase transitively depends on, not just the ids listed in apply.requires
• Always read dependency artifacts before creating a new one - re-read from disk, not from conversation memory (files may have changed since you last saw them)
• 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
