Design Lab
Use this skill in the current agent. Do not ask the user to switch agents.
When To Use
Use Design Lab when the user asks for:
- Multi-model design or planning
- Multi-model review or critique
- Comparing plans or answers from multiple AI models
- Blind or anonymous review of model plans
- Current-code review with multiple models
How To Run
Prefer native OpenCode Task fanout when possible:
- If you are already running as
design_lab, do not load this skill again or
delegate back to design_lab; run the workflow directly.
- In the current/default agent, do not call
task with subagent_type: "design_lab". That hides the model workers one level down.
- Instead, call native
task directly for each selected design_lab_model_*
agent. Each model worker should appear as a top-level task card in the current
OpenCode session.
- The loaded skill owns model selection, output paths, manifests, and synthesis
when running from the current/default agent.
- If native Task tool fanout is unavailable, call the
design_lab_run tool as a
fallback bridge.
Use workflow: "auto" unless the user clearly requested one of these workflows:
ask: ask every configured model the same prompt
plan: generate independent model plans
revise: revise existing model plans
blind_review: anonymously review existing model plans
code_review: review current code or current changes
Pass each model worker a complete prompt with the user's request, the workflow,
and its exact output_file. Do not ask model workers to call other agents.
Direct Fanout Workflow
Use this path from the normal build or current/default agent:
- Read
.opencode/design-lab.json or .opencode/design-lab.jsonc if present.
- Select matching
design_lab_model_* agents from the native Task tool's
available agent list. Use all model agents unless the user selected a subset.
- Create a run directory under the configured
base_output_dir or .design-lab
using a short timestamp/topic slug.
- Write the original prompt to
prompt.md and write a manifest.json with
selected agent names, output files, skipped agents, and workflow.
- Call native
task once per selected design_lab_model_* agent. Launch all
independent model tasks before waiting when possible.
- Give each worker one exact output file, such as
responses/<agent-suffix>.md,
plans/<agent-suffix>.md, or reviews/code-review-<agent-suffix>.md.
- After tasks finish, verify output files exist and have useful content.
- Write
summary.md with consensus, disagreements, recommended answer or
findings, and failures.
- Reply with a concise summary and paths. Do not paste full model responses into
chat.
Review Safety
For current-code reviews, reviewer subagents must not modify source code. Present
findings first. Only edit source code after the user explicitly asks for fixes.
Fallback
If both native delegation and design_lab_run are unavailable, tell the user to
restart OpenCode after installing or rebuilding the Design Lab plugin. If
configuration is missing, tell the user to run /design-lab:init.
