Sidebar tools provide cross-cutting capabilities beyond the lens paradigm.
Automated linter running 16+ rules across nodes, requirements, interfaces, and trace links. Shows health score and actionable findings with navigate-to-source.
A live agentic Python notebook (Pyodide, in-browser). Seeded from the project model’s real parameters, an AI analyst writes and runs cells, reads its own figures, and pressure-tests findings — power, mass, mission timelines, and more. Notebooks save as portable .ipynb assets; published result files become first-class outputs. BYOK or managed.
Full ChangeSet history with operation-level detail. Every AI edit and manual change is recorded with timestamps, specialist identity, and undo capability.
AI cost tracking ledger. Shows total estimated spend, breakdowns by provider/category/model, recent API calls with token counts, and CSV export. Updated automatically on every API call.
Trace link explorer showing satisfies, verifies, derives, and depends_on relationships between requirements, verifications, and nodes.
Unit system management with SI base units, derived units, and custom type definitions for interface signals and properties.
Asset browser for all generated files — images, meshes, scripts, simulation results. Stored locally in IndexedDB via Dexie.js.
API key configuration (Anthropic, Gemini), model preferences, project metadata, naming conventions, and export options.
