A typed, inference-capable ontology (TBox + ABox) plugin for DeepSeek Harness — durable domain knowledge the agent declares, asserts against, and queries under schema constraints.
Codex-style attachment formats for the DeepSeek Harness Web GUI: PDF text-layer extraction, Office text extraction, scanned-PDF OCR, long-document spill + index cards, image-to-PNG.
Options plate on the DeepSeek Harness composer's + button — pick files and folders from the project or anywhere on the machine, upload from your device, or run a slash command — with inline path chips and a Claude Code-style attachment preview.
