One Complete Devin Design Task
A Devin Design Task, From Brief to Interface
A single task, shown end to end: the brief and constraints you hand over, the artifact that comes back, and the checks you still run before it is done. The interface below is an illustrative example built for this page, not a recorded Devin run.
1Design Brief and Constraints
BriefDesign the getting-started section of a developer docs site: navigation, an article with a callout and code, and an on-this-page rail. Hand the whole section back as one reviewable file. Desktop and phone.
- Design systemOpenDesign paper canvas: Albert Sans, one green accent
- Breakpoints1440px desktop and 390px mobile, no horizontal scroll
- InteractionsSidebar navigation, copy code, on-this-page highlight
- OutputOne self-contained HTML file with stable
data-od-idhooks
2Division of Work: You, Devin and OpenDesign
- You
Write the brief, select the design system and define the acceptance criteria.
- Devin
Plans the layout, writes the HTML, CSS and JavaScript and revises it on request.
- OpenDesign
Provides the design system and skill, renders the preview and stores every version as a file in the project.
- Review
Visual hierarchy, spacing on the 8px grid, both breakpoints and every interaction are checked before handoff.

4Review Before Handoff
Layout
Grid and Spacing
Three columns on the 8px grid; the article measure stays under 72 characters.
Hierarchy
Visual Hierarchy
Title, callout, then steps; the accent marks the active navigation item only.
Responsive
Mobile Layout
Navigation becomes a sheet; the on-this-page rail folds into a jump menu.
Interaction
Interaction Checks
Copy the code, jump to a heading, open the navigation sheet.
Fit
When Devin Fits the Task, and When It Does Not
Devin Fits When
- Autonomous multi-step builds. Devin plans and executes whole front-end tasks — scaffolding, wiring components, running and testing — instead of stopping at a snippet.
- Sandboxed cloud handoff. Longer builds can hand off to a cloud agent with its own computer and keep running after you step away.
- Project rules + browser verification. Project context carries your conventions; a real-browser render checks output across breakpoints against your references.
- Account-based, model choice. Sign in with a Devin account; Devin runs on frontier models, including Cognition’s own SWE-1.6.
Choose Another Workflow When
- You need editable vector files. The artifact is HTML, not an editable design document. Check a separate vector workflow for your required asset format.
- You have no reference and no constraints. Without a design system or examples the output tends toward a generic look; write the brief first.
- You do not have the credential this agent needs. Required: Devin (Cognition) account — account-based sign-in, not BYOK. OpenDesign does not provide or proxy credentials.
- Your team works in Codex or Claude Code. Those agents have their own pages; the workspace is the same, the setup differs. See related agents.
Compatibility
Devin Requirements Before You Start
This guide covers Devin as connected through the OpenDesign desktop app. Published references checked on 6 September 2026.
Tool ScopeDevin, by Cognition
Devin for Terminal is the command-line version of Devin, Cognition’s autonomous AI software engineer. It runs as a local coding agent with access to your codebase, tools, and environment, planning and executing multi-step tasks on its own. This page is about designing interfaces with Devin through OpenDesign, not about Devin’s own interface. OpenDesign’s setup notes list the available agents.
Accounts and AuthenticationDevin (Cognition) account — account-based
Devin (Cognition) account — account-based sign-in, not BYOK. Authenticate with your Devin (Cognition) account — credentials stay with your agent on your machine. This page does not promise a quota or price.
System and VersionsDesktop app or source
Check the download page for desktop builds. The Node.js and pnpm requirements in the source quickstart apply to running from source, not to installing a desktop package. Minimum compatible Devin version: not verified here.
Connection CheckThe success signal
Follow the connection instructions shown by your installed version, then run a small task. Confirm that Devin handled it and that the artifact opens. A download alone does not establish a working connection.
Start with the desktop app
Devin Setup in Three Steps
Download first, complete the Devin setup for your installed version, then check a small result. You do not need to build OpenDesign from source to follow this path.
- 1
Download the OpenDesign Desktop App
Choose the package for your computer, install it and open the app.
Download OpenDesignCHECKPOINTThe desktop app opens. Already installed? Move to the next step; there is no need to download again. - 2
Prepare Your Devin Connection
Follow the Devin instructions in your installed version. Authenticate with your Devin (Cognition) account — credentials stay with your agent on your machine.
Devin documentation# 1. Install Devin for Terminal curl -fsSL https://cli.devin.ai/install.sh | bash # 2. Start it in your project and sign in on first run cd your-project devin # sign in with your Devin (Cognition) accountFrom the Devin setup notes in the published guide; check the vendor documentation for the current command.
CHECKPOINTConfirm the intended agent and account. If it is unavailable, check compatibility before trying a larger task. - 3
Run One Small Devin Task
Use a small brief so you can judge the whole loop, including one revision.
Starter briefBuild a settings screen with a profile form and a save confirmation. Use my design rules. Check it at desktop and mobile widths.
CHECKPOINTOpen the result, test the save state and request one specific change. A generated file is the beginning of review, not the end.
To run OpenDesign from source, follow the technical quickstart instead.
The Devin design workflow
The Devin Design Workflow in Five Steps
The same docs page task, followed from brief to verified file. Each step lists what you provide, what Devin does, what OpenDesign contributes and what you check.
- 1
Design Brief
Plain language, three to six lines. Name the audience, the job of the screen and the platforms.
- YouWrite the brief; attach a reference screenshot if you have one.
- DevinReads the brief and the project’s instruction file; asks when something is ambiguous.
- OpenDesignProvides the project, the prompt surface and the skill for the artifact type.
- CheckConfirm the brief states the acceptance criteria. Adding them now is cheaper than after generation.
- 2
Design Constraints
A design system and a few hard rules. This is what separates on-brand output from a generic look.
- YouPick a design system; state breakpoints and any must-use components.
- DevinLoads the DESIGN.md tokens and posture rules into context before writing a line.
- OpenDesignShips the design-system library and binds the chosen one into the skill template.
- CheckThe tokens match your brand. One accent, the right fonts, the right radius.
- 3
Generate the Interface
Devin writes a self-contained HTML file: layout, styles, interactions and stable hooks.
- YouWait, or answer a clarifying question. Nothing to configure.
- DevinPlans the sections, writes the HTML, CSS and JavaScript, runs the file and fixes what fails.
- OpenDesignSaves the artifact into the project folder and indexes it for preview.
- CheckNothing yet. Judge the file after it is rendered, not from the source.
- 4
Preview
The file renders inside OpenDesign at the widths you asked for. This is where the design is judged.
- YouSwitch widths, click through the interactions, leave comments on elements.
- DevinReads your comments on the preview and prepares the next revision.
- OpenDesignRenders the preview, exposes
data-od-idtargets for comments and edits. - CheckHierarchy, contrast, overflow at 390px, focus states, and whether the accent is used sparingly.
- 5
Revise and Verify
Request changes by pointing at elements in the preview. Every revision is a new file; nothing is overwritten silently.
- YouTurn comments into requests; decide when the task is done.
- DevinApplies the changes in place and re-runs the file.
- OpenDesignKeeps versions side by side; exports an image or the HTML when you are done.
- CheckRe-check only the area that changed, then the whole page once at each breakpoint.

Limitations
Devin Limitations, Manual Checks and Fallbacks
- ScopeIt can hand a session off to a sandboxed cloud agent that keeps working asynchronously, so longer builds finish after you close your laptop. This page covers Devin as an agent connected to OpenDesign, not every Devin feature.
- Usage LimitsUsage limits and cost follow the credential you use (Devin (Cognition) account — account-based sign-in, not BYOK). This page makes no claim about free quotas.
- NetworkLocal project files do not mean offline inference. Review your agent’s provider settings and data policies before sharing sensitive inputs.
- Output Is HTMLArtifacts are HTML files, not vector design files.
- Manual ReviewAccessibility, real content, brand fit and interaction correctness are reviewed by you in the preview. Treat any self-check by the agent as a first pass.
- FallbackIf the agent is unavailable or a task fails, check the installed version’s connection instructions and authentication. Preserve the error and the last working artifact before changing configuration.
FAQ
Common Questions About Devin and OpenDesign
Can Devin for Terminal Really Do Design Work?
Yes — with an aesthetic skill, a design system, and real reference images in context, Devin produces production-quality, responsive UI, and as an autonomous agent it can build, run, and verify the result against your references. Without that context it tends to default to a generic look, which is the gap OpenDesign fills.
How Do I Sign in to Devin?
Devin is account-based: you sign in with a Devin (Cognition) account rather than bringing your own model key. Install Devin for Terminal, run it in your project, and authenticate on first run. OpenDesign never proxies your credentials — your agent uses them directly.
What Makes Devin Good for Design Specifically?
It is a fully autonomous software engineer: it plans and executes multi-step front-end builds end to end, and can hand a session off to a sandboxed cloud agent that keeps working after you step away. Taste still comes from the design system, skill, and references you supply.
Devin or Claude Code for Frontend Design?
Both are strong. Claude Code is known for specific, codebase-aware design decisions; Devin’s edge is fully autonomous, end-to-end execution with a sandboxed cloud handoff. Many teams use both — OpenDesign lets you switch agents without changing your design workflow.
Does Devin Run in a Sandbox?
Devin for Terminal runs locally with access to your codebase and environment, and it can hand a session off to a cloud agent that runs in its own sandboxed environment — useful for longer builds, tests, and PR creation that continue asynchronously.
