Set up your project

Add OpenSpec to a project: run init, see what it wrote, and adjust it.

Pick where OpenSpec lives

• In your repo (the default): specs and changes sit next to the code they describe and are versioned with it. The rest of this page follows this path.
• In a store: a separate planning repo shared by the repos that use it, for multi-repo setups or keeping planning out of the repo entirely. Stores (beta) covers when that's worth it and how to set one up.

Initialize your project

With the CLI installed (Installation), run init at the root of your project. In your terminal:

cd <your-project>
openspec init

Init asks which AI tools you use, writes the workflow files for the ones you pick, and reports what you got:

OpenSpec Setup Complete

Created: Claude Code
6 skills and 6 commands in .claude/
Config: openspec/config.yaml (schema: spec-driven)

Restart your IDE for the new commands to take effect.

Re-running init is safe:

• Tools you already set up print Refreshed instead of Created.
• Running init again with a new tool selected adds that tool.
• The --tools flag skips the picker (CLI reference).

What init installs

Running init creates two things in your project:

• An openspec/ folder at the repo root
• Workflow files (skills and commands) added to your AI tool's folder (.agents/, .claude/, etc.)

Commit all of it like the rest of your source (FAQ covers why). Init changes nothing else in your repo (if it finds leftovers from an older OpenSpec version, it asks before cleaning them up).

The openspec/ folder

Every OpenSpec artifact lives here, at the root of your project. Here's what that looks like:

openspec/
├── config.yaml     project settings and context for the AI
├── specs/          your specs (empty for now)
└── changes/        in-motion changes (empty for now)
    └── archive/    completed changes move here

Concepts explains both artifacts; Project config covers config.yaml.

The workflow files (skills and commands)

These are the OpenSpec workflows, the actions you'll use as you work. Here they are as installed skills, in the shared .agents/ folder most tools use:

.agents/skills/
├── openspec-explore/              think through an idea first
├── openspec-propose/              propose a change
├── openspec-apply-change/         implement a change's tasks
├── openspec-update-change/        revise a change's plan
├── openspec-sync-specs/           sync a change's spec updates into specs/
├── openspec-archive-change/       move a finished change to the archive
├── openspec-verify-change/        check the implementation matches the plan (not included by default)
└── openspec-bulk-archive-change/  archive several changes at once (not included by default)

This is the default set plus two optional workflows. Profiles lists all twelve.

By default each workflow installs in two forms:

• Skill (openspec-apply-change): instructions your agent picks up on its own when you ask for the work.
• Command (/opsx:apply in Claude Code): a typed entry point for the same workflow, under a shorter name.

The two are functionally identical. A workflow's skill and its command carry the same instructions.

Why two: commands came first, and every tool spells them its own way. Skills are the newer standard shared across tools, but not every tool can invoke a skill directly, so commands stay as those tools' entry point.

Some tools install in skill form only. Where the tool runs skills directly, init skips commands and says so (Commands skipped for: codex (uses skills)).

We prefer skills and expect to retire commands eventually.

Change what gets installed

The interactive picker changes the delivery form and the workflow set (Profiles). In your terminal:

openspec config profile

Here's switching to skills only:

Current profile settings
  Delivery: both

? What do you want to configure? Delivery only
? Delivery mode (how workflows are installed): Skills only

Config changes:
  delivery: both -> skills
? Apply changes to this project now? (Y/n) y

Answering yes applies it to the current project on the spot. Other projects pick it up on their next openspec update. The setting is global, per machine.

Setup is done. The Quickstart takes your first change from here.
