elodin

Author, instantiate, and execute agentic QA test case plans for Elodin releases. Use when the user asks to create a QA plan, test case plan, or release test checklist, add or edit test cases, or run/execute a QA test plan for a release.

Develop and calibrate simulations against experimental truth data using elodin monte-carlo. Use when vendoring real telemetry as a reference profile, adding a truth-replay ghost entity, writing campaign specs/hooks and run scoring, reconstructing missing data channels from physics, or iterating on guidance and physics models with campaign feedback.

Deploy and configure AlephOS on flight computers, write flight software services, and manage NixOS modules for the Aleph platform. Use when working with aleph/, deploying to Jetson Orin hardware, writing NixOS modules, flashing firmware, or composing a flight software stack.

Contribute to the Elodin Editor, the 3D viewer and graphing tool. Use when editing files in libs/elodin-editor/ or apps/elodin/, working on the Bevy/Egui UI, modifying viewport rendering, telemetry graphs, video streaming, KDL schematics, or the command palette.

Create and modify physics simulations using the Elodin Python SDK. Use when writing or editing simulation Python files, defining components or systems, spawning entities, configuring 6DOF physics, setting up visualization, or integrating with SITL/HITL workflows.

Work with the Cranelift JIT MLIR backend. Use when modifying libs/cranelift-mlir/, adding new StableHLO ops, debugging simulation correctness issues, running the checkpoint diagnostic tool, or working on the pointer-ABI tensor runtime.

Develop and contribute to the Elodin codebase. Use when building Elodin from source, running tests, modifying core libraries, working on the Rust workspace, or onboarding as a contributor.

Reduce the size of glTF/GLB 3D assets to cut Git LFS bandwidth/storage while keeping them loadable by the editor's Bevy 0.18 glTF loader. Use when shrinking .glb/.gltf files in assets/, addressing LFS quota/bandwidth, or when a model is too large. Produces plain glTF 2.0 (no Draco/meshopt/quantization, which Bevy cannot read).

Tips for working with a Bevy application

Profile Elodin with Tracy. Use when profiling the editor, simulation, building with tracy features, capturing traces, analyzing performance, or adding custom instrumentation.

Contribute to the Elodin Python SDK (nox-py). Use when editing PyO3 bindings in libs/nox-py/, adding new Python API surface, modifying the JAX integration, working on component/system compilation, or changing the Python package in python/elodin/.

Work with the Nix development environment and NixOS configurations in Elodin. Use when troubleshooting nix develop, modifying flake.nix, adding Nix packages, setting up OrbStack VMs for Linux builds on macOS, or developing Aleph NixOS modules.

Work with Elodin-DB, the time-series telemetry database. Use when running elodin-db, writing client integrations (C, C++, Rust, Python), configuring replication/follow mode, querying data via the Lua REPL, or connecting the Elodin Editor to a database.
