Use **`/opsx:apply`** to implement tasks from a change. The agent reads `tasks.md`, works through tasks one by one, writes code, creates files, runs tests as needed, and checks off completed items wit

Use **`/opsx:archive`** to finalize a completed change. Archives by merging delta specs into the main `openspec/specs/` directory and moving the change folder to `openspec/changes/archive/`.

Use **`/opsx:bulk-archive`** to archive multiple completed changes at once. Validates each change, detects spec conflicts across changes, and resolves them by checking what is actually implemented.

Manage OpenSpec configuration at two levels: **project config** (`openspec/config.yaml`) for project-specific context and rules, and **global CLI config** (`openspec config` subcommands) for user-leve

Use **`/opsx:continue`** to create the next artifact in the dependency chain. This builds a change incrementally — one artifact at a time — giving the user control to review and edit before proceeding

Use **`/opsx:explore`** to think through ideas, investigate problems, compare options, and clarify requirements — all without creating any artifacts or committing to a structure. When insights crystal

Use **`/opsx:ff`** to fast-forward through all planning artifact creation at once. Creates all artifacts in dependency order (proposal -> specs -> design -> tasks) in a single pass.

Run **openspec init** to initialize OpenSpec in a project: creates the `openspec/` directory (specs, changes, config) and configures AI tool integrations (skills and slash commands). This skill assume

Install the [OpenSpec CLI](https://github.com/Fission-AI/OpenSpec) so that `openspec` is available globally. This skill covers only **installing the CLI**; it does not run `openspec init`. For project

Use **`/opsx:new`** to start a new change. This creates the change folder structure under `openspec/changes/<name>/` with metadata (`.openspec.yaml`) and prepares the first artifact for creation.

Use **`/opsx:onboard`** for a guided, interactive tutorial through the complete OpenSpec workflow. The tutorial uses the user's actual codebase — finding real improvement opportunities, creating a rea

Use **openspec schema** subcommands to create and manage custom workflow schemas. Schemas define what artifacts exist and their dependencies. The default `spec-driven` schema provides proposal -> spec

Use **`/opsx:sync`** to merge delta specs from a change into the main `openspec/specs/` directory without archiving the change. The change remains active after sync. This is optional — **openspec-arch
