description: Update an OpenSpec change by revising its existing planning artifacts and keeping them coherent with one another. Use when the user wants to revise a change's plan, fold new decisions into it, or reconcile its artifacts after an edit. Also use when the user says "openspec update change" or "opsx update". If the user means the openspec update CLI command, which refreshes generated files, run that command instead. Never edits code.

Revise a change's existing planning artifacts and keep them coherent. Never edit code.

**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.

**Project check:** These steps expect a project that already uses OpenSpec. Before the first step that writes anything (`new change`, `archive`, `sync specs`, or authoring an artifact file), confirm the project has a root: run `openspec list --json` (with `--store <id>` when a store is selected, since the store is then the root) and read `root`. A root object means the project is set up. `"root": null` means it is not - there is no `openspec/` directory here, and a write such as `openspec new change` would create one as a side effect. The command also exits non-zero, which is that answer rather than a broken CLI, so read the JSON instead of retrying or working around it.

One `"root": null` is not about setup: when a `status` error message starts with `Declared in` or `Invalid store declaration in` and names this project's `openspec/config.yaml` (or `config.yml`), the project does use OpenSpec through a store it declares, which this machine cannot resolve (the store is not registered, or the `store:` line is malformed). Do not treat it as uninitialized and skip the branches below: stop before writing and show the user that error's `message` and `fix`.

Otherwise, with no root, what happens next depends on how this workflow was reached:

- **Auto-selected**: you chose this workflow yourself, without the user naming OpenSpec, naming this skill, or running its slash command. Stop using OpenSpec and answer the request normally, as you would with no OpenSpec installed. Do not ask them to set anything up and do not mention OpenSpec setup.
- **Explicit OpenSpec request**: the user named OpenSpec, named this skill, or ran its slash command. Stop before writing and ask how to proceed: set this project up (`openspec init`), target a store they already have (`--store <id>`), or continue without OpenSpec for this request. Wait for their answer.

In both branches, never create the root as a side effect: do not run `openspec init` until the user asks for it, do not hand-create `openspec/` files, and do not let a command create it.

**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.

This workflow revises artifacts that already exist; `/openspec-continue-change` is what creates the ones that do not.

**Steps**

1. **Select the change**

   If a name is provided, use it. Otherwise:
   - Infer from conversation context if the user mentioned a change
   - Auto-select if only one active change exists
   - If ambiguous, run `openspec list --json` to get available changes sorted by most recently modified, and ask the user to select one

   When prompting, present the top 3-4 most recently modified changes as options, showing:
   - Change name
   - 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 update.

   Always announce: "Using change: <name>" and how to override (e.g., `/openspec-update-change <other>`).

2. **Get the change's artifacts**
   ```bash
   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", "skipped", "ready", "blocked")
   - `isPlanningComplete`: Boolean indicating if all planning artifacts are complete. Older CLI versions expose the same value as `isComplete`.
   - `planningHome`, `changeRoot`, `artifactPaths`, and `actionContext`: path and scope context. Use these instead of assuming repo-local paths.

   The artifact ids and paths come from the active schema - do NOT assume them, and do NOT branch on hardcoded artifact names. Custom schemas must work unchanged.

   The files to edit are `artifactPaths.<id>.existingOutputPaths` - the concrete files that exist on disk, already glob-expanded for glob artifacts (e.g. `specs/**/*.md`), plus any confirmed concrete path allowed under a partly populated glob artifact (step 4). Do NOT write to `resolvedOutputPath`: for a glob artifact it is still the glob pattern, not a real file.

3. **Understand the request**
   - If the user asked for a specific revision ("the design now uses X"), that is the starting edit.
   - If they
