From 47f3bfecfcd6c6786e72701309840bc766477217 Mon Sep 17 00:00:00 2001 From: chiguyong Date: Tue, 23 Jun 2026 15:05:01 +0800 Subject: [PATCH] feat(documents): add document processing capability (U1-U9) Implements end-to-end document generation, template filling, and reading: - DocumentService: unified business layer for create/query/download - Renderers: Word (Markdown->docx), Excel (Markdown/JSON->xlsx), PDF (Markdown->pdf with CJK font), Template (Jinja2 sandbox .docx fill) - DocumentLoader: read PDF/Word/Excel/Markdown/HTML/text -> Document - DocumentTool: Agent tool with action=create|read - REST API: /api/v1/documents (create, upload-template, list, download) - Frontend: DocumentPanel, DocumentCard, documents Pinia store, chat store tool_result detection - Security: path traversal guard (Path.resolve + relative_to), SSTI guard (SandboxedEnvironment), API key auth, 50MB upload limit - Bug fixes: template path traversal (400 not 500), TemplateRenderer lazy-load (no external registration dependency) - Tests: 168 tests (unit + security + E2E F1/F2/F3 + bug hunt) - Docs: README section 17, requirements + plan + test-plan docs Requirements R1-R28 verified, F1-F3 user flows pass. --- README.md | 81 +++ ...ment-processing-capability-requirements.md | 152 +++++ ...06-23-002-feat-document-processing-plan.md | 405 +++++++++++++
