Use Spec Kitty in OpenCode

Tier: supported. Citation (accessed 2026-05-21): https://opencode.ai/docs

Prerequisites

  • Spec Kitty CLI installed. See Install Spec Kitty.
  • Project initialized for this harness: 
    spec-kitty init --ai opencode
  • OpenCode installed and configured. Follow the OpenCode documentation for installation and authentication.

Where Spec Kitty installs files

Per the supported-harnesses matrix, OpenCode uses the slash-command mechanism. Spec Kitty installs:

  • Directory: .opencode/command/ (note: singular command, not commands)
  • Files: spec-kitty.specify.md, spec-kitty.plan.md, spec-kitty.tasks.md, spec-kitty.implement.md, spec-kitty.review.md, spec-kitty.accept.md, spec-kitty.merge.md, spec-kitty.dashboard.md, spec-kitty.status.md, spec-kitty.charter.md, spec-kitty.analyze.md, spec-kitty.research.md.

Canonical invocation

Inside OpenCode, slash commands are invoked as:

/spec-kitty.specify "<one-line mission description>"
/spec-kitty.plan
/spec-kitty.tasks
/spec-kitty.implement WP01

Worked example

  1. From your project root, launch OpenCode.
  2. At the prompt, type: 
    /spec-kitty.specify "a hello world page"
  3. Spec Kitty's interview prompts appear — answer them inline.
  4. When asked for a kebab-case slug, supply something short, e.g. hello-world-page.
  5. The mission spec lands at kitty-specs/hello-world-page-<mid8>/spec.md.

Troubleshooting

  • /spec-kitty.* commands do not appear. Run spec-kitty agent config sync from the repo root. This rewrites .opencode/command/ from the canonical source templates. Restart OpenCode.

  • Profile not loading. Run inside OpenCode:

    /ad-hoc-profile-load researcher-robbie

    Use the profile id from the work-package frontmatter.
