OPSX: Propose

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

Planning boundary: This workflow creates planning artifacts only. The user request that selected or triggered this workflow authorizes planning only, even if it asks to build or fix something. Do not edit project code. After the planning artifacts are complete, stop. Do not start implementation in the same response, even if the initial request asks for it. Wait for a new user request after the artifacts are presented; then start the apply workflow.

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-path>/spec.md (what the system must do - a delta, not the main spec)
• design.md (how)
• tasks.md (implementation steps)

<capability-path> is the spec directory relative to specs/ (for example, user-auth or identity/user-auth). Preserve an existing capability's full path and follow the project's established organization for new capabilities.

When the user is ready to implement, they must start the apply workflow explicitly.

---

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, schemas, view). Once selected, treat --store <id> as sticky for the rest of the workflow. Every unscoped example of those commands below is shorthand: before running it, append the flag. For example, run openspec status --change "<name>" --json --store "<id>", not the unscoped form shown below. 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 argument after /opsx:propose is the change name (kebab-case), OR a description of what the user wants to build.

Steps

1. Understand the request and clarify material ambiguity

   If no input is provided, 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.

   If the request contains ambiguity that would materially affect scope, externally observable behavior, compatibility, or acceptance criteria, ask the user before creating the change. For minor details, make a reasonable assumption and record it in the planning artifacts.

2. Load project context

   Run openspec context --json from the current working directory (or openspec context --json --store "<store-id>" when a registered store was explicitly selected). Use the returned root.path as the authoritative OpenSpec root. If context reports no_openspec_root, stop without creating or changing any files. Offer openspec init and wait for the user to request initialization. Do not initialize automatically or run openspec new change. After initialization, rerun this context check before continuing. For any other context failure, stop and report the error; do not fall back to the current directory or run later OpenSpec commands without the selected store.

   Only when context returns a resolved root.path, read <root.path>/openspec/config.yaml. Use config.yml only when config.yaml does not exist. If neither file exists, continue without project context. Do not fall back to config.yml if config.yaml is unreadable or invalid.

   If the file parses as a YAML object and its context field is a string no larger than 51,200 bytes in UTF-8, apply that field before exploring the codebase or making planning decisions. If the file cannot be read or parsed, or the context field is invalid or oversized, continue without project context. Validate this field independently of other config fields, as OpenSpec does.
