v1.0.25 — arxiv MCP + tool-toggle settings (whiteboard)
What's new in the whiteboard
The whiteboard panel now has a small gear icon in its top-right corner. Tap it to control which tools the whiteboard agent can reach for during generation:
- Web search — default on (existing behaviour). Lets the agent look up cited prior work or unfamiliar terms.
- arXiv — default off. Flip it on and the agent can fetch papers from arxiv.org by id or query, useful when a paper directly cites a prior work whose mechanism the diagram needs to name correctly. Downloaded papers land next to the paper's index files (per-paper, never your home dir).
Settings persist across reloads. Changes take effect on the next "Generate" or "Refine" without cancelling anything in flight.
Under the hood Fathom now picks up fathom-whiteboard 0.1.14, which ships the vendored arxiv stdio MCP and the cache-friendly system-prompt boundary.
