SpacetimeDB TypeScript server module SDK reference. Use when writing tables, reducers, or module logic in TypeScript.

io.github.NVIDIA/skills/vss-deploy-detection-tracking-3d

Deploy and operate the RTVI-CV-3D microservice as MV3DT (`MODE=mv3dt`): per-camera DeepStream perception plus BEV Fusion over calibrated cameras. Supports the bundled sample dataset, custom video files, and RTSP streams, and chains to `vss-generate-video-calibration` when calibration is missing. Use `vss-deploy-profile` for the full warehouse blueprint and `vss-deploy-detection-tracking-2d` for single-camera 2D detection.

TypeScript coding standards — apply when writing, reviewing, or refactoring .ts/.tsx, or naming/renaming .ts files (camelCase casing).

io.github.abhigyanpatwari/GitNexus/gitnexus-impact-analysis

Use when the user wants to know what will break if they change something, or needs safety analysis before editing code. Examples: "Is it safe to change X?", "What depends on this?", "What will break?"

io.github.abhigyanpatwari/GitNexus/gitnexus-guide

Use when the user asks about GitNexus itself — available tools, how to query the knowledge graph, MCP resources, graph schema, or workflow reference. Examples: "What GitNexus tools are available?", "How do I use GitNexus?"

io.github.abhigyanpatwari/GitNexus/gitnexus-exploring

Use when the user asks how code works, wants to understand architecture, trace execution flows, or explore unfamiliar parts of the codebase. Examples: "How does X work?", "What calls this function?", "Show me the auth flow"

io.github.abhigyanpatwari/GitNexus/gitnexus-debugging

Use when the user is debugging a bug, tracing an error, or asking why something fails. Examples: "Why is X failing?", "Where does this error come from?", "Trace this bug"

io.github.abhigyanpatwari/GitNexus/gitnexus-cli

Apply when adding new test cases, debugging test failures, or setting up test infrastructure.

io.github.exceptionless/Exceptionless/backend-architecture

io.github.PostHog/posthog/writing-evals

Teaches how to write and run evals on the `products/posthog_ai/eval_harness/` harness — sandboxed agent suites that execute the real coding agent in a Docker or Modal sandbox against a seeded Hedgebox project, and one-shot suites that score a single in-process model invocation per case. Use when adding or changing eval suites, cases, scorers, seeders, or synthesizers under `products/posthog_ai/evals/` or `products/*/evals/`, when touching the harness under `products/posthog_ai/eval_harness/`, or when running or debugging those evals (`hogli evals`).
