Design Debate is an agent skill from Owl-Listener/designpowers. Use when a design direction is uncertain, when the team could go multiple ways, or when the user wants to see competing approaches argued before committing — orchestrates structured debate between agents who advocate for different directions
Its SKILL.md is about 2.1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Frontend & Design. The repository describes itself as: An agent design team you control: 10 agents that run an inclusive design process while you direct. The licence is MIT.
7 steps, taken from the step headings in SKILL.md.
Read from SKILL.md and the folder at commit cb00757. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
No scripts in the folder and no shell commands in SKILL.md (its code samples are markdown).
From the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Design Debate loads about 2.1k tokens when it runs. Until then it costs about 64 tokens; SKILL.md has 740 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

.claude/skills/design-debate/SKILL.md (or your agent's skills folder).Good design decisions come from tension, not consensus. When agents converge too quickly, they optimise for agreement instead of the best answer. This skill creates productive conflict — agents argue for competing directions with real trade-offs, and the user decides.
Define the design question precisely. A debate without a clear question produces noise.
Format:
DESIGN QUESTION: [Specific, answerable question]
CONTEXT: [Brief context from design-state.md]
CONSTRAINTS: [Non-negotiable requirements from brief, accessibility, taste profile]
STAKES: [Why this decision matters — what it affects downstream]Example:
DESIGN QUESTION: Should the onboarding flow use a multi-step wizard or a single scrollable page?
CONTEXT: App for first-time pet owners, ages 25-45. Primary persona has mild anxiety about "doing it right."
CONSTRAINTS: Must be completable in under 3 minutes. Must work on mobile. Must not require account creation upfront.
STAKES: Sets the interaction pattern for all future multi-step flows in the app.Select 2-3 agents to argue for different directions. Each agent argues FOR their assigned position — they are advocates, not neutral analysts.
| Role | What They Argue |
|---|---|
| Advocate A | The case for Direction A — strengths, evidence, personas it serves best |
| Advocate B | The case for Direction B — strengths, evidence, personas it serves best |
| Advocate C (optional) | A third direction, a hybrid, or a "neither — here's why" position |
Assign agents based on their expertise:
| Agent | Best suited to advocate for |
|---|---|
| design-strategist | UX patterns, information architecture, user flow approaches |
| design-lead | Visual directions, layout models, component architecture |
| content-writer | Content strategy approaches, tone directions, naming conventions |
| motion-designer | Interaction paradigms, feedback models, transition approaches |
| accessibility-reviewer | The most inclusive option, cognitive load implications |
| design-scout | Evidence-backed positions from competitive research |
Each advocate delivers their argument in this format:
## [Agent Name] argues for: [Direction]
### The Case
[2-3 paragraphs making the strongest possible argument for this direction.
Be specific — reference the brief, personas, principles, and evidence.]
### Who This Serves Best
[Which personas benefit most and why]
### Who This Serves Least
[Which personas might struggle and why — be honest]
### Trade-Offs
[What you give up by choosing this direction]
### Evidence
[Research, patterns, competitive examples, or design principles that support this]Rules for advocates:
After all advocates present, each gets one round of rebuttal:
### [Agent Name] responds to [Other Agent]:
[1-2 paragraphs directly addressing the strongest point of the opposing argument.
Concede what is true. Challenge what is weak.]This prevents echo-chamber advocacy — each agent must engage with the other side's best arguments.
Before presenting to the user, the accessibility-reviewer evaluates all proposed directions:
## Accessibility Assessment
| Direction | Accessibility Impact | Concern Level |
|-----------|---------------------|---------------|
| Direction A | [Assessment] | Low / Medium / High |
| Direction B | [Assessment] | Low / Medium / High |
[If any direction creates accessibility barriers, flag it clearly.
This is not an argument for a direction — it is a constraint check.]If a direction has High accessibility concern, it should be flagged prominently in the presentation to the user. The user can still choose it, but they should know the cost.
Show the debate to the user in a structured format:

DESIGN DEBATE
Question: [The design question]

DIRECTION A: [Name]
Argued by: [agent]
[2-3 sentence summary of the case]
Best for: [personas]

YOUR CALL: Which direction do you want to take?

or propose a hybrid.)

design-state.md Decisions Log with rationaledesign-memoryNot every debate needs the full process. Scale the depth to the stakes:
| Stakes | Debate Format |
|---|---|
| High (sets architectural pattern) | Full debate: 2-3 advocates, cross-examination, accessibility review |
| Medium (affects multiple screens) | Quick debate: 2 advocates, no cross-examination, accessibility flag |
| Low (affects one component) | Micro debate: 2 options presented as a simple comparison table, user picks |

|---|---|
| Debating after the user has decided | Wastes time. If the user has a direction, execute it |
| Debating trivial decisions | 8px vs 12px padding is not a debate — it's a design system decision |
| Agents being polite instead of advocating | "Both options are great!" is not a debate. Agents must argue to win |
| Presenting a debate without accessibility review | Every direction must be evaluated for inclusion before the user chooses |
| Running a debate in auto mode without pausing | Debates ALWAYS pause for user decision — they are inherently direct-mode moments |
| More than 3 directions | Too many options cause decision paralysis. If there are more than 3, narrow down first |

A skill your agent uses when a design direction is uncertain, when the team could go multiple ways, or when the user wants to see competing approaches argued before committing — orchestrates…. Design Debate is an agent skill from Owl-Listener/designpowers.
Design Debate fits situations like: A design direction is uncertain; the team could go multiple ways.
Run `npx skills add Owl-Listener/designpowers --skill design-debate -a claude-code`. Or copy the skill folder (skills/design-debate in Owl-Listener/designpowers) into .claude/skills/design-debate in your project. Claude Code loads it when a task matches its description.
Run `npx skills add Owl-Listener/designpowers --skill design-debate -a codex`. Or copy the skill folder (skills/design-debate in Owl-Listener/designpowers) into .agents/skills/design-debate in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add Owl-Listener/designpowers --skill design-debate -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/design-debate, .gemini/skills/design-debate, .github/skills/design-debate and .opencode/skills/design-debate in your project.
SKILL.md names no scripts, command-line tools or credentials: Design Debate is instructions for the agent only.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Design Debate is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 2.1k tokens (SKILL.md is roughly 8.3k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
