How to add a design review gate to your pull requests
Install the TheDesignAgent GitHub App, or add one GitHub Actions workflow, and every pull request's preview deploy gets its changed pages reviewed for UX and visual quality, with one updating PR comment and a check that fails below your threshold.

Twelve MCP servers worth connecting to Claude Code, Codex or Cursor when you build UI, grouped by the job they do: design context, components, up-to-date docs, the browser, quality checks, generation and deploys.
8 min readConceptsTheDesignAgent vs Claude Design: designing before the build, reviewing during it
Claude Design is where you design with Claude before you build: prototypes, slides and one-pagers using your brand, handed off to Claude Code. TheDesignAgent works inside the coding agent's loop on every screen it builds: a brief before, scored UX and visual reviews after. They cover different moments, and they work together.
4 min readConceptsTheDesignAgent vs Figma MCP: which does your coding agent need?
Figma MCP tells your coding agent what the design is. TheDesignAgent briefs the build and checks whether the result fits the user's job and holds up visually. They work on opposite sides of the build, and most teams that have a Figma file benefit from both.
4 min readConceptsWhy does AI-generated UI look AI-generated?
Because coding agents design from defaults instead of from the job. They don't know who uses the screen, what that person is trying to do, or what your product has already decided, so they reach for the most common pattern. Here are the tells, why they happen, and what actually fixes them.
6 min readConceptsThe best AI design agents in 2026, and which job each one does
AI design tools now do five different jobs: generating UI from a prompt, bridging design files and code, shaping how a site looks, checking one layer such as accessibility, and working as a design agent inside the coding agent's loop. Here are ten worth knowing, grouped by job, with where each fits and where it stops.
8 min readWorkflowAdding design review to your agent: what the workflow looks like
How to add a design judgment step to Claude Code, Cursor, or any agent that builds UI. What to call, when to call it, how to read the response, and what the loop looks like across multiple builds.
5 min readPatternsAffordance density: how much belongs on a row before it stops being readable
Agents solve row density in one of two ways: everything visible (unreadable) or almost nothing visible and everything behind a click (high-ceremony). The right answer is a calibrated three-tier model.
5 min readConceptsCognitive load is three things, not one
Most design principles treat cognitive load as a single dial to turn down. It isn't. CLT has three sources that behave differently — and reducing the wrong one makes a screen worse.
6 min readConceptsComponent grammar: when shadcn defaults stop being neutral
Shadcn's defaults are a position, not a blank slate. When agents apply them unchanged, the result reads as AI-built before the user consciously registers why.
5 min readAnti-patternsConfirm everything: why agents wrap routine actions in "Are you sure?"
The confirmation dialog is the agent's safety net. Applied to every action, not just destructive ones, it creates an interrupt-heavy experience that slows down every workflow it was meant to protect.
4 min readConceptsDay-shape: why one persona has many jobs, and your UI needs to know which one is loaded
Most users don't have one job — they have several, and they shift between them across the workday. Designing for 'the user' without day-shape means designing for the average of all their jobs, which usually fits none of them well.
5 min readPatternsDecision surfaces: putting the action where the eye already is
A decision surface is a layout where each row is a unit of decision and the action is on the record. It's what agents should build when the job is deciding, not watching.
5 min readConceptsWhy order fulfillment punishes friction harder than financial review
Extraneous load is near-fatal in warehouse operations and tolerable in loan underwriting. Good UX isn't universal — the same pattern can be right in one domain and wrong in another.
5 min readConceptsJTBD lives in three places: corpus, project profile, and score
Jobs-to-be-Done isn't a single lookup. In TheDesignAgent it shows up in three distinct places — and the evaluation only makes sense when all three are in play.
5 min readAnti-patternsModals all the way down: why agents bury decisions you'd put on the row
The modal reflex is one of the most consistent patterns in agent-built UI. A button opens a dialog. The action lives in the dialog. Save closes it. It compounds in batch workflows.
4 min readPatternsOutputs that update as you decide: the summary is a side-effect, not a dashboard
Decision surfaces need a running total. Not a KPI strip showing system state — a summary that reflects what the user has decided so far. These are different numbers, and agents build the wrong one.
4 min readPatternsProgress rails: layouts that mirror the sequence of work, not its categories
A progress rail is the shape that emerges when a sequential job gets the interface it needs. Not a wizard, not a stepper, not tabs — something closer to a spatial map of the work already done and the work still ahead.
5 min readWorkflowReading the score trajectory: why convergence beats absolute fit
A single fit score tells you where a build is. A score trajectory tells you whether it's getting better, plateaued, or regressing — and which dimensions are moving. The second question is usually the more important one.
5 min readConceptsThe component library was the right answer to a problem agents no longer have
Component libraries exist because building UI was expensive and inconsistency was hard to prevent. AI agents changed the cost equation. The case for building unencumbered — and what you need instead.
5 min readAnti-patternsThe 8-field form: why agents collect what the schema has, not what the job needs
Agents build forms from data models. A schema with twelve fields produces a form with twelve fields. The job usually requires three. This is how to close that gap.
4 min readAnti-patternsThe filter buffet: every column gets a filter, none of them get used
Agents build filters from columns. A table with ten columns gets ten filter controls. The user's actual filtering question involves two of them. The rest is noise that teaches the interface to be ignored.
4 min readWorkflowThe first call is discovery: why the init prompt sets the frame for everything after
The first time a build agent calls TheDesignAgent with no prior context, something different happens. Not just a score — an inference of domain, persona, jobs, and day-shape. Every evaluation that follows is calibrated to what was learned here.
5 min readWorkflowThe full design process, end to end: what an evaluation actually looks at
TheDesignAgent doesn't evaluate one thing. It runs through the same process a skilled human design reviewer would — JTBD, cognitive patterns, visual craft, visual cognitive load, component grammar, accessibility — encoded as a rubric an agent can call mid-build.
6 min readConceptsThe missing design layer: why AI coding agents ship UI without a judgment step
The AI coding stack has linters, test runners, type checkers, and deployment gates. It has no design review step. This isn't an oversight — it's a hard problem. Here's why it's still unsolved and what solving it actually requires.
6 min readConceptsThe tools agents reach for (and the design layer most setups still miss)
Claude Code, Codex and Cursor can reach dozens of MCP tools for code, data, deployment and communication, and a growing set of design tools. Most of those design tools cover one layer: accessibility, a Figma file, or how the site looks. This is what agents have available, and what's still missing from most setups.

The JTBD was correct. The workflow was sound. The screen still felt like work to look at. A visual lens evaluation on a loan review tool where the problem wasn't structure — it was parse cost.
6 min readConceptsVisual cognitive load: when a screen is well-designed and still hard to look at
A screen can be JTBD-aligned, cognitively appropriate for the job, and still be hard to parse. Visual cognitive load is the mental cost of reading the layout itself — paid before any task thinking starts.
6 min readConceptsWhat Figma access gives agents — and what it doesn't
Agents can now read Figma files, extract components, and pull design tokens. This is useful for implementation fidelity. It doesn't solve design judgment. Here's why the gap between 'access to designs' and 'understanding of design intent' is still wide.
5 min readConceptsWhy there's no UX linter (and what it would take to build one)
ESLint catches code that violates rules. There's no equivalent for UI that violates design principles. The reason isn't that nobody tried — it's that design correctness isn't rule-shaped.
5 min readConceptsTwo lenses, one pipeline: why UX and visual review are different jobs
A single rubric kept producing the same shape of answer regardless of what the agent was actually getting wrong. Splitting it in two fixed that.
5 min readAnti-patternsThe dashboard default: why agents build viewers when the job is deciding
Four KPI cards, a table, a date filter. The dashboard is the agent's lowest-effort answer to 'build me a tool for this data.' It's also wrong most of the time.
