sigilmakes

Build or modify Rust4D primitives and tetrahedral meshes. Use when touching rust4d_math::Mesh4D, primitives, Tesseract4D, ShapeTemplate geometry variants, or any code that creates 4D tetrahedra for slicing.

Run autonomous visual checks for Rust4D rendering changes. Use after touching WGSL shaders, RenderUniforms, camera projection, slice pipeline, primitives, or examples that affect rendering.

Final quality gate for Rust4D feature branches. Use before PRs, releases, or after broad engine changes. Covers formatting, tests, clippy, rustdoc, visual captures, docs, and scratchpad handoff.

Rust4D math, matrix, rotation, and GPU layout conventions. Use when editing rust4d_math, Camera4D, WGSL shaders, projection matrices, GPU uniform structs, or anything passing matrices between Rust and the GPU. Prevents convention-mismatch bugs (row/column major, depth range, rotation planes, struct layout).

Verify the slice-plane invariant when changing Rust4D camera, movement, physics, or rendering code. Use before and after touching Camera4D, CharacterController4D, SimulationSystem, the slice shader, projection, or movement input handling. Explains the invariant, why it breaks, the regression tests, and the headless visual verification workflow.

Use the gh CLI for GitHub issues, PRs, comments, checks, and Actions state in this repo (sigilmakes/hades). Use whenever reading or writing GitHub state from an agent session.

Hades is a Kubernetes-native agent OS kernel, not an app. Use when editing src/, adding a resource kind, or wiring a capability. Encodes the kernel/userland boundary, the HTTP capability model, and the branch/test rules.

Commit and open a pull request against feature/integration (never main). Use when you have changes ready to submit — after implementing, testing, and self-reviewing.

Review changes against feature/integration before opening a PR or when the user asks for review. Checks correctness, the kernel/userland boundary, edge cases, regressions, test gaps, and resource-kind checklist compliance.

Persistent JavaScript REPL for orchestration — async subagents in tmux sessions, file I/O, tool wrappers, MCP server integration. Use when chaining operations, spawning parallel agents, calling MCP tools, or transforming data programmatically.

Execute a plan autonomously using sub-agent loops in spindle. Takes a plan (markdown task list, kanban board, or scratchpad plan), parses it into tasks, and loops sub-agents over them with review cycles and git-backed state. Use when asked to "work through this plan", "ralph over this", "autopilot", "execute this plan autonomously", or "loop over these tasks".
