Figma Weave Forgetting Design System Rules: How to Fix

When using Figma Weave to generate layouts, edit components, or apply variables, the AI can suffer from "context drift." You may notice that during the first few prompts of a session, Weave accurately respects your published design systems, auto layout rules, and component libraries. However, as the session goes on, the model begins to forget these constraints, hallucinating custom colors, ignoring nested components, or applying hardcoded values instead of your defined design tokens.

This behavior is typically caused by a saturated context window, local cache bottlenecks, or broken schema mapping between Figma's canvas and the Weave AI engine.

Why Figma Weave forgets your design system rules

Figma Weave relies on a context window that holds your active file schema, imported library metadata, and prompt history. Every time you issue a new prompt, Weave processes the entire current state of your canvas selection along with your instruction history.

If you are working in a large file with thousands of layers, or if your session has been active for a long time, the context window fills up. When this happens, Weave prioritizes your immediate instructions and begins dropping "older" context—which often includes your global style libraries, variable collections, and brand guidelines.

How to fix Figma Weave context loss

Follow these troubleshooting steps to clear Weave's memory cache, rebuild its local index, and force the model to respect your design system constraints.

1. Reset the Weave session context To fix immediate model drift, you need to clear the active conversation memory. This flushes the accumulated token history without affecting your actual canvas design.

1. Locate the Weave panel or floating bar in your Figma workspace.
2. Click the More options (three dots) icon or the settings cog.
3. Select Reset Session or Clear Chat History.
4. Close and reopen the Weave panel.

This forces Weave to re-scan your current canvas selection and library mappings with a clean slate.

2. Isolate the target frame Feeding an entire complex page into Figma Weave degrades performance and dilutes the model's focus. Restrict the data Weave has to process by isolating your working assets.

1. Select only the specific frame or component you want Weave to modify.
2. Right-click the selection and choose Copy link to selection or isolate it on a clean draft page.
3. Use the "Selected Layers Only" option in Weave (if visible) to ensure it does not scan the rest of your file's layer tree.

3. Force-reload your library connections If Weave is generating components that ignore your active libraries, the background schema sync may have stalled.

1. Open your Figma file and press Ctrl + / (Windows) or Cmd + / (macOS) to open the Quick Actions menu.
2. Type Manage Libraries and press Enter.
3. Toggle your primary design system library Off, wait 5 seconds, and toggle it back On.
4. Reload your Figma tab or restart the Figma Desktop App (Cmd + R or Ctrl + R).

4. Structure prompts with explicit variable calls When Weave's automatic library detection fails, you can force compliance by explicitly referencing your tokens in the prompt. Weave responds better to structured, declarative constraints than to vague, conversational requests.

• Weak prompt: "Make this card look like our brand style."
• Effective prompt: "Apply our primary brand variables to this card. Use the color token brand/primary-blue for the background and the text style body/medium for the copy."

5. Clear Figma's local cache Corrupted local cache files can prevent Weave from reading updated component schemas and variables.

• On macOS: Quit Figma. Open Finder, press Cmd + Shift + G, paste ~/Library/Application Support/Figma/ and delete the files inside. Restart Figma.
• On Windows: Close Figma. Open the Run dialog (Win + R), type %APPDATA%\Figma and press Enter. Delete the contents of this folder and relaunch the app.

When to escalate

If Figma Weave continues to generate styles outside of your design system even after a full cache clear and session reset, there may be a platform-level issue or a bug in the Weave API library parser.

Check with your organization's Figma Administrator to ensure your seat has the proper library permissions and that your design system variables are fully published to your team space. If admins confirm everything is configured correctly, submit a support ticket via Figma's Help Center, providing the specific file URL and details about which library styles Weave is failing to recognize.
