Agent Skills: OpenSpec Fast-Forward Skill

OpenSpec Fast-Forward Skill

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.

When to Use

• The user has a clear picture of what to build and does not need incremental review.
• The user says "fast forward", "create everything", "generate all planning docs".
• Small to medium features where step-by-step review is unnecessary.

Prerequisites

• An active change exists (created via openspec-new or /opsx:new).
• Or use /opsx:ff <change-name> to create and fast-forward in one step.

Workflow

1. Run fast-forward

   • /opsx:ff — fast-forward the current/inferred change.
   • /opsx:ff <change-name> — fast-forward a specific change.

2. Artifacts are created in dependency order

   • In the default spec-driven schema:
     1. proposal.md — why and what
     2. specs/**/*.md — delta specs (requirements and scenarios)
     3. design.md — technical approach
     4. tasks.md — implementation checklist
   • Each artifact reads its dependencies before being created.

3. Review

   • All planning artifacts are now available. The user can edit any of them before proceeding.

Outputs

• All planning artifacts created in openspec/changes/<name>/:
  • proposal.md
  • specs/**/*.md
  • design.md
  • tasks.md

Next Steps

• Review and edit artifacts if needed.
• Use openspec-apply to implement tasks.
• Or use openspec-verify after implementation to validate.

Troubleshooting

• "Change not found": Specify the name: /opsx:ff add-dark-mode.
• Artifact quality issues: Use /opsx:continue instead for more control; add project context in openspec/config.yaml (see openspec-config).
