Restyling components? Check behavior before changing them

Use Devin with component copies, styles and baseline screens to prepare a styling migration and interaction checklist through the test workflow below, then review it. Matching tools and permissions are required.

Execution environment and usage

AI / software

Devin

Where to operate

Devin web workspace: select a test project, plan in Ask and move to Agent only for approved changes.

Getting started

  1. Sign in to the Devin web workspace and select the test project. Start in Ask; switch to Agent only for approved execution.
  2. Supply component copies, styles and baseline screens and the prompt below. Confirm the scope before allowing necessary actions.
  3. Inspect the resulting styling migration and interaction checklist; record anything not run or not verified.

Setup and plan requirements

Requires access to Devin, authorized test data and a matching runtime; file writes and shell commands must stay within approved scope. Preparation: Provide authorized component copies, the target styling system, design rules and baseline views.

Prompt portability limits

Adapt the wording to another coding assistant only after separately configuring files, runtime, test tools and integrations. Renaming the tool does not establish compatibility.

Usage limitations

Start by reading data and proposing changes; no automatic writes or commands are authorized. Approve the runtime and commands separately for subsequent tests.

適用情境 / When to use

Use Devin with component copies, styles and baseline screens to prepare a styling migration and interaction checklist through the test workflow below, then review it. Matching tools and permissions are required. The account emphasizes runnable tests and project conventions.

步驟 / Steps

  1. Provide authorized component copies, the target styling system, design rules and baseline views.
  2. Plan component-level conversion using existing colors and styles rather than redesigning.
  3. Check states, keyboard interaction, semantics, focus and responsive behavior.

提示詞 / Prompt

Before converting [component copy] from [current styling system] to [target system], map styles, states and interactions. Preserve [existing design rules/colors/fonts] rather than choosing a new theme. Implement an approved branch only, validating appearance, keyboard use and focus with [existing tests/manual acceptance]. List unsupported and untested areas; do not merge or deploy automatically.

留意事項 / Cautions

  • Screenshots alone cannot establish behavioral parity.
  • Do not remove interactions or accessibility requirements to pass tests.

來源限制 / Evidence limits

A team experience does not establish lossless conversion; visual similarity does not establish accessibility.

流程說明 / Workflow note

These steps and prompts are original, untested exercises by this site, not the author’s verbatim workflow. Reported results do not guarantee exercise outcomes.
