Continue working on an OpenSpec change by creating the next artifact. Use when the user wants to progress their change, create the next artifact, or continue their workflow.
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.
Start a new OpenSpec change using the experimental artifact workflow. Use when the user wants to create a new feature, fix, or modification with a structured step-by-step approach.

How to write and maintain commands in .opencode/commands/<name>.md.
A command defines a repeatable process kicked off by a slash command. It should be self-contained: everything needed to execute the workflow is in the command file.
| Command (workflow) | Not a command |
|---|---|
| /ship -- verify, commit, PR | Answering "what should I work on?" (agent) |
| /work -- pick issue, set up env | How to write good commit messages (skill) |
| /prune -- clean merged worktrees | Deciding priority order (agent) |

Phase-based flow: Break workflows into numbered phases with clear boundaries. Each phase has a single responsibility. This makes commands easy to follow, debug, and modify.
Decision trees over prose: Use tables and if/then structures for branching logic. Commands often have multiple paths -- make them explicit, not buried in paragraphs.
Delegate to agents: Commands compose agents, they don't duplicate agent logic. If an agent knows how to create PRs, the command delegates to it rather than reimplementing PR creation.
Explicit stop points: Define exactly when to STOP and ask the user. Especially at:
Report at the end: Every command ends with a summary of what happened. The user should know what changed without re-inspecting.
Commands are the most brittle extension point because they hard-code workflows that compose agents and tools. When an agent's interface changes, commands that delegate to it may break.
When updating a command:
When an agent changes:
