Fast-forward through artifact creation - generate everything needed to start implementation in one go.

**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 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**
   ```bash
   openspec new change "<name>"
   ```
   This creates a scaffolded change in the planning home resolved by the CLI.

3. **Get the artifact build order**
   ```bash
   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:
        ```bash
        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 <artifact-id>"

   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**
   ```bash
   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 `/openspec-apply-change` 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, suggest continuing that change instead
- Verify each artifact file exists after writing before proceeding to next
