Workspace & Semantic Memory

The Workspace provides a full-featured, sandboxed file management environment and integrated IDE combined with an automated Semantic Memory (RAG) indexing engine.

1. Integrated IDE & Viewersโ€‹

ActonOS includes specialized viewers tailored for different file formats:

  • Code Editor (CodeMirror): Syntax highlighting, auto-indentation, line numbers, and error linting for 50+ programming languages.
  • Markdown Live Preview: Split-pane or full-width rendering with GitHub-flavored tables, task lists, and LaTeX equations.
  • Interactive JSON Viewer: Collapsible tree navigation with key search and type annotations.
  • Data Table Viewer: Spreadsheet-like tabular viewer for .csv and .tsv files with sorting and filtering.
  • Media & Document Viewer: Inline previewing of images (.png, .jpg, .svg), audio, video, and PDF documents.

2. File Operations & Batch Managementโ€‹

  • Upload & Download: Upload single files or entire folders. Download individual items or export multi-file selections as a compressed .zip archive.
  • Context Menus: Right-click any file to Rename, Duplicate (_copy), Move, or Delete.
  • Storage Statistics: The Workspace stats bar displays total storage used, file counts, and storage breakdown by category (Code, Documents, Data, Media).

3. Automated Semantic Memory (Local Vector RAG)โ€‹

Every text document, markdown file, or source code file placed in /data/workspace/ is automatically processed into the Hybrid Semantic Memory index:

  1. Debounce Queue (1-Minute): Edits are enqueued in a durable SQLite debounce table to avoid thrashing during rapid file modifications.
  2. Chunking: Text is split into semantic paragraphs with sliding window overlaps.
  3. Local ONNX Embeddings: Chunks are vectorized using the local multilingual-e5-small model running in the loopback embeddingd daemon.
  4. Hybrid Retrieval: Agents can query /api/workspace/chunks or execute hybrid search across SQLite FTS5 (lexical) and Chromem-go (vector).
  5. Manual Reindex: Click the Reindex Semantic Memory button anytime to force a complete re-embedding of the workspace.
