WalkthroughAdds new design-token API endpoints and utilities: GET /api/{version}/tokens, GET /api/{version}/tokens/{category}, GET /api/{version}/tokens/all, plus token utilities, OpenAPI entries, and Jest tests covering success, filtering, and error cases. Changes

In `@src/utils/tokens.ts`:
- Around line 129-149: Update the function comment for filterTokensByCategory to
accurately describe its behavior: it filters tokens within each category by
token name (case-insensitive) using filterTokens and returns only categories
that still have matching tokens; replace the current misleading lines about
matching the category name and ensure the docstring references TokensByCategory
and the filter parameter semantics.
🧹 Nitpick comments (3)
src/pages/api/[version]/tokens.ts (1)
15-30: Serialize error details to avoid{}responses.
JSON.stringify(Error)drops message/stack. Consider normalizing to a string for consistent debug info.♻️ Proposed adjustment
- } catch (error) { - return createJsonResponse( - { error: 'Failed to load tokens', details: error }, - 500, - ) - } + } catch (error) { + const details = error instanceof Error ? error.message : String(error) + return createJsonResponse( + { error: 'Failed to load tokens', details }, + 500, + ) + }src/pages/api/[version]/tokens/all.ts (1)
35-38: Avoid returning raw error objects in API responses.
details: errorcan leak internals or serialize unpredictably; return a sanitized message instead.🔧 Suggested adjustment
- } catch (error) { - return createJsonResponse( - { error: 'Failed to load tokens', details: error }, - 500, - ) - } + } catch (error) { + const message = error instanceof Error ? error.message : String(error) + return createJsonResponse( + { error: 'Failed to load tokens', details: message }, + 500, + ) + }src/utils/tokens.ts (1)
85-103: Optional: sort tokens within each category for deterministic output.
This can make responses stable and easier to diff/consume.♻️ Suggested refinement
for (const token of tokens) { const category = getCategoryFromTokenName(token.name) if (!byCategory[category]) { byCategory[category] = [] } byCategory[category].push(token) } + + for (const categoryTokens of Object.values(byCategory)) { + categoryTokens.sort((a, b) => a.name.localeCompare(b.name)) + }

Fix docstring: filtering is by token name, not category name.
The comment conflicts with the implementation and could mislead readers.
📝 Suggested doc fix
- * Filters tokens by category (case-insensitive)
- * Matches against the category name
+ * Filters tokens by name across categories (case-insensitive)
+ * Matches against the token name field📝 Committable suggestion
