Fix 22 pre-existing Biome TypeScript lint violations across 6 files: - noExplicitAny: replace (import.meta as any) with typed cast in App.tsx - noGlobalIsNan: isNaN → Number.isNaN in productPreviewUnavailable.ts - noNonNullAssertion: current! → current?.toFixed(2) in MandateApproval.tsx - noSvgWithoutTitle: add <title> elements to all 5 inline SVGs (MandateApproval.tsx ×4, InventoryOptionsCard.tsx ×2) - useButtonType: add type="button" to all 7 button elements missing it (App.tsx ×3, MandateApproval.tsx ×2, InventoryOptionsCard.tsx ×1, MonitoringCard.tsx ×1) - useExhaustiveDependencies: destructure messages from chatState so useEffect dep array references a stable value - useOptionalChain: proseText && proseText.trim() → proseText?.trim() in MessageRenderer.tsx (×2) - useSemanticElements: div[role=button] → <button> in InventoryOptionsCard.tsx (onKeyDown handler removed as buttons natively handle Enter/Space)

Code Review
This pull request improves the web client's code quality by adding explicit button types, enhancing accessibility with SVG titles, and replacing unsafe non-null assertions with optional chaining and nullish coalescing. It also refines TypeScript environment variable typing, simplifies conditional rendering logic, and adopts safer NaN checking. Feedback identifies an HTML nesting violation where div elements are placed inside a button, suggests consistent string quoting and variable destructuring, and notes a minor formatting issue.

Changing this element to a <button> is a good semantic improvement. However, please note that <button> elements are only allowed to contain phrasing content. The current implementation contains several <div> elements (which are flow content) as descendants (e.g., lines 25, 41, 46). This results in invalid HTML. To fix this, you should change the internal <div> elements to <span> and use CSS (like display: block) to maintain the desired layout.

While destructuring messages here satisfies the useExhaustiveDependencies lint rule for the useEffect below, the rest of the component continues to use chatState.messages (e.g., lines 169, 171). For better consistency and readability, consider destructuring all the properties used from chatState at the top of the component, or use the destructured messages variable throughout.

The closing bracket > for the <button> tag is placed on its own line without indentation, which appears to be a formatting oversight. It should be moved to the previous line or properly indented.

The use of double quotes for the string literal "0.00" is inconsistent with the single quotes used for other string literals in this file (e.g., line 152 uses '—'). Using single quotes here would maintain consistency with the project's apparent style.

Consistent with the previous comment, consider using single quotes for the string literal '0.00' to match the surrounding code style.
| value: hasCurrentPrice ? `$${current?.toFixed(2) ?? "0.00"}` : '—', | |
| value: hasCurrentPrice ? `$${current?.toFixed(2) ?? '0.00'}` : '—', |
The word 'sublabel' (used as a JSX prop name in MessageRenderer.tsx) is not in any standard dictionary. Add both cases to suppress the cspell CI false positive.
Fix all remaining lint violations across the full web-client source
so that BIOME_LINT passes on all TypeScript files in the repo:
Biome fixes:
- useTemplate: string concat → template literals in useChat.ts (×2)
- useExhaustiveDependencies: add fetchMandate to sendToAgent deps;
add monitoringData?.qty to auto-poll useEffect deps; reference
messages.length in App.tsx scroll effect callback
- noNonNullAssertion: guard getElementById('root') with null check
- noUnusedImports: remove MonitoringStatus from mandateEntries.ts
- noUnusedFunctionParameters: msg → _msg, tc → _tc in toolCallEntries
- noUnusedVariables: remove unused args variable in toolCallEntries
- useButtonType: add type="button" to CopyButton and card-header
button in MandateCard.tsx
- noArrayIndexKey: replace key={i} with key={d.salt??d.key??String(i)}
- noSvgWithoutTitle: add <title> to SVGs in ReceiptCard.tsx and
UserActionCard.tsx
Prettier fixes:
- mandateEntries.ts: break long import (>80 chars) to multi-line,
remove triple-blank-line block
Both are used as meaningful shorthand terms in the web-client source: - dedup: abbreviation of deduplicate (used in useChat.ts, mandateEntries.ts) - sublabel: UI prop name in UserActionCard / MessageRenderer
…e files Run prettier --write on all 12 modified TypeScript/TSX files to bring them into full compliance with the project's .prettierrc config. No logic changes — formatting only. Biome lint errors were fixed in the previous commits; this commit solely addresses TYPESCRIPT_PRETTIER CI failures caused by pre-existing style inconsistencies that were surfaced when super-linter checked the modified files.
The project uses Biome for TypeScript/TSX quality (BIOME_LINT). Super-linter itself warns in CI output that running Biome and ESLint simultaneously on TSX files causes conflicts and recommends disabling one. Disable the ESLint-based checkers so Biome is the single source of truth for TypeScript quality. The ESLint checks were also producing false positives: - TSX: react/react-in-jsx-scope is not required for React 17+ JSX transform; super-linter's ESLint also lacks node_modules so every module import is flagged as unresolvable - TYPESCRIPT_ES: browser APIs (fetch, crypto.randomUUID) are flagged as unsupported Node.js built-ins because super-linter treats all TS as server-side Node.js rather than browser code
HTML spec forbids flow content (div) inside a button element. Replace the inner layout divs in ItemRow with span elements and add `display: block` to the SCSS rules for .item-name, .item-id, .item-price and .item-stock so they continue to render as block boxes. Also consistently use the destructured `messages` variable throughout App.tsx instead of mixing chatState.messages and messages. Addresses Gemini code-review feedback on PR google-agentic-commerce#249.

Thanks for the update, @chopmob-cloud. The changes look correct and address the points raised in the review. I have no further comments on this PR. |
Stylelint requires: - rgb() instead of rgba() with alpha-value-notation: percentage (color-function-alias-notation + color-function-notation rules) - Unquoted font-family names for non-generic custom fonts (font-family-name-quotes rule) Converts rgba(52, 211, 153, 0.15/0.3) to rgb(52 211 153 / 15%/30%) and removes quotes from the "Geist" font-family declarations. These were pre-existing violations exposed by the previous commit touching the file.

Friendly nudge — this PR has been clean and mergeable since 2026-04-29 with all 4 checks green ( Worth flagging because this is the unblocker for the open AP2 PR queue: the same 22 biome lint errors + 10 warnings that this PR fixes are currently inherited by every other open PR against Scope of this PR is intentionally narrow:
Happy to rebase or address feedback within the day if a maintainer has a window for a look this week. Thanks for considering 🙏 |

The
Lint Code Basejob still fails due to super-linter ESLint configuration issues that pre-exist in the repo and appear on any PR that touchescode/web-client/src/TypeScript files:n/no-missing-import,react/react-in-jsx-scope): super-linter's built-in ESLint config treats TSX files as Node.js code and requiresimport React(React 16 pattern). The project'seslint.config.js(ESLint v9 flat config) correctly omits this for React 17+, but super-linter uses its own legacy config.n/no-unsupported-features/node-builtins): browser APIs (fetch,crypto.randomUUID) flagged as unsupported Node.js features — because super-linter doesn't know this is a browser app.These would need to be fixed in the super-linter configuration (
.github/linters/or the workflow itself), not in the source code.Test plan
