Problem

Potential Problems:Building UI components blind: Without a way to preview how a component will look in context, developers commit to a full build cycle before knowing whether the layout, placement, or content actually works as intended.Expensive feedback loops for UI changes: In a traditional workflow, seeing the result of a UI change requires building, deploying, and testing, which is slow and costly for what is often an iterative, visual process.Misalignment between design intent and implementation: Stakeholders and developers often have different mental models of what a component will look like. Without a visual preview to anchor the conversation, misunderstandings persist until the component is already built.Risky manifest changes with no pre-flight check: Modifying or removing existing UI components without previewing the effect can introduce layout breaks or missing information that only become visible after deployment.No approval gate before committing to a build: Starting a manifest build without a confirmed, reviewed preview means effort can be invested in a direction that gets changed or rejected partway through.Difficult to communicate UI proposals to non-technical stakeholders: Describing a proposed UI change in words or static mockups is less effective than showing an annotated before-and-after screenshot of the actual live application.

Example

You've planned a new UI component or manifest change and want to verify how it will look in the live app before committing to the full build cycle.

Solution Overview

Previewing a UI component before building it begins with a plain-language description of what needs to be added, changed, or removed on a specific page. The tool interprets this instruction and constructs a preview specification that defines the component type, its data sources, its layout, and where in the page it should appear.To make the preview accurate, the tool reads the current structure of the live application page, giving it the context needed to position the component correctly within the real environment rather than against a generic template. The component is then injected into the page using JavaScript, meaning no manifest changes or deployments are required at this stage.Before and after screenshots are captured automatically, with the affected area visually annotated to make the change immediately clear. These screenshots serve as a shared reference point for the team and any stakeholders involved in reviewing the proposal.If the initial result is not quite right, feedback can be given in plain language and the tool adjusts and re-injects the component accordingly. This refinement loop continues until the preview reflects the intended outcome, without any of the overhead of a formal build cycle at each iteration.Once the preview is approved, that approval is recorded and acts as the gate for the next stage: the formal manifest build. This ensures that effort invested in building and deploying the component is only committed once there is a confirmed, reviewed visual to build from, rather than midway through a direction that may change.
