name: openspec-ff-change
description: Fast-forward through OpenSpec artifact creation. Use when the user wants to quickly create all artifacts needed for implementation without stepping through each one individually. Also use when the user says "openspec ff" or "opsx ff".

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.
**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**: 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)
- **Inspect the relevant project before drafting**: Read `context` and `rules` first, then inspect relevant implementation, nearby tests, configuration, and docuTrust audit

Questions
What does the openspec-ff-change — fission-ai/openspec skill do?
Spec-driven development (SDD) for AI coding assistants.
Is openspec-ff-change — fission-ai/openspec safe to install?
The audit found nothing in the source that contradicts what it says it does, and graded it B (89/100). Grade A is held back for packages that have also passed a sandboxed behavioural run, which is why a clean skill reads B.
What can openspec-ff-change — fission-ai/openspec access on my machine?
The audit observed no filesystem, network or shell use at all in its source.
How current is this page?
The grade is for one exact copy of the source (6cfcf327ccd6), read on 2026-10-26. The repository is watched, and a new audit runs when it changes — this is the first audit.
