Critical issue: The enablePdfMultimodal parameter is being passed to parseMentions() but it's not defined anywhere in this function. This will cause a runtime error. Did you mean to get this from the provider state or pass it as a parameter to processUserContentMentions?

Using any type here bypasses TypeScript's type safety. Could we define a proper interface for the document block structure instead?
| const documentBlock: any = { | |
| interface PdfDocumentBlock { | |
| type: 'document'; | |
| source: { | |
| type: 'base64'; | |
| media_type: 'application/pdf'; | |
| data: string; | |
| }; | |
| cache_control: { type: 'ephemeral' }; | |
| } | |
| const documentBlock: PdfDocumentBlock = { |
| // interact with the file system and would require actual PDF files | ||
| // or mocking to test properly. Since the project doesn't use mocking | ||
| // in its test suite, these would be better tested as integration tests | ||
| // with actual test PDF files. |

The comment acknowledges that extractPDFAsBase64 and validatePDFForMultimodal need testing but doesn't include them. These are critical functions handling file I/O and validation. Could we add at least basic tests with mock PDF data or test fixtures?

The function checks if the file exists with fs.stat but doesn't verify if it's readable before attempting to open it for magic byte validation. Consider adding a try-catch around the file operations or checking read permissions:
| const fileHandle = await fs.open(filePath, "r") | |
| try { | |
| const fileHandle = await fs.open(filePath, 'r') | |
| const buffer = Buffer.alloc(5) | |
| await fileHandle.read(buffer, 0, 5, 0) | |
| await fileHandle.close() | |
| const magicBytes = buffer.toString('ascii') | |
| if (magicBytes !== '%PDF-') { | |
| return { valid: false, error: 'File does not appear to be a valid PDF (invalid magic bytes)' } | |
| } | |
| } catch (error) { | |
| return { | |
| valid: false, | |
| error: `Failed to read PDF file: ${error instanceof Error ? error.message : String(error)}` | |
| } | |
| } |

The function now returns a union type that could be confusing for callers. Consider adding JSDoc to clarify when each type is returned, or perhaps create a discriminated union with a type field to make it clearer:
| export async function extractTextFromFile( | |
| /** | |
| * Extracts text content from a file, with support for various formats including PDF, DOCX, XLSX, and plain text. | |
| * For large text files, can limit the number of lines read to prevent context exhaustion. | |
| * | |
| * @param filePath - Path to the file to extract text from | |
| * @param maxReadFileLine - Maximum number of lines to read from text files. | |
| * Use UNLIMITED_LINES (-1) or undefined for no limit. | |
| * Must be a positive integer or UNLIMITED_LINES. | |
| * @param multimodal - When true and file is PDF, returns base64 encoded content for multimodal analysis | |
| * @returns Promise resolving to either: | |
| * - String with line-numbered text content (default) | |
| * - Object with base64 PDF data when multimodal=true and file is PDF | |
| * @throws {Error} If file not found, unsupported format, or invalid parameters | |

I don't think this implementation is correct |
Summary
This PR implements native PDF multimodal analysis support in Roo Code, enabling users to upload PDFs that will be analyzed for both text and visual content (charts, diagrams, tables) by AI models that support this capability.
