This skill should be used when working on Godot Engine projects. It provides specialized knowledge of Godot's file formats (.gd, .tscn, .tres), architecture patterns (component-based, signal-driven, resource-based), common pitfalls, validation tools, code templates, and CLI workflows. The `godot` command is available for running the game, validating scripts, importing resources, and exporting builds. Use this skill for tasks involving Godot game development, debugging scene/resource files, implementing game systems, or creating new Godot components.

Validate spec-implementation-test alignment and convergence for spec groups. Checks spec completeness, atomic spec coverage, implementation evidence, test evidence, and traceability. Use after implementation and tests are complete.

Use when a template-source change needs a safe, low-risk smoke test. Render scaffold into a temporary instance, then run validate_agent_docs.sh and doctor.sh on the rendered target without touching backend runtime execution.

Generate an ML-centric PRD for ML-Ralph. Use when planning an ML project, experiment plan, or when asked to create an ML PRD. Triggers on: create a prd, write prd for, plan this ML feature, requirements for, spec out.

Refactor code structure while preserving behavior, filling test gaps as needed

Run the Firegame catann test workflow (start dev server, run test script, and collect screenshots/logs).

Set up or refine open-source .NET code-quality gates for CI: formatting, `.editorconfig`, SDK analyzers, third-party analyzers, coverage, mutation testing, architecture tests, and security scanning. Use when a .NET repo needs an explicit quality stack in `AGENTS.md`, docs, or pipeline YAML.

Keep ICN gateway API behavior, exported OpenAPI spec, and generated TypeScript SDK types in sync. Use when modifying icn-gateway routes, request/response models, auth behavior, or any API shape that can cause OpenAPI/SDK drift.

Use this skill when editing src/parsers, src/instruments, src/domain, or parser-backed normalization code and tests. Trigger on tasks involving trace export parsing, normalization, ranking inputs, adapter contracts, or schema stability. Do not use for unrelated CLI or documentation-only changes.

Use when working on nex-editor architecture or implementation, especially the Rust editor core, runtime facade, WASM bridge, browser playground, or cross-platform rendering protocol.

Invoke parallel document-specialist agents for external web searches and documentation lookup

Handle Netlify Forms in TanStack Start. Use when implementing contact forms, signup forms, or any form submission handling on Netlify-hosted TanStack Start sites.

academic-search

Performs GraphQL introspection queries to discover schema, types, queries, mutations, and subscriptions. Assesses schema completeness and identifies security concerns.

Automated security scanning for dependencies, code, containers with Trivy, Snyk, npm audit. Use for CI/CD security gates, pre-deployment audits, compliance requirements, or encountering CVE detection, outdated packages, license compliance, SBOM generation errors.

Maintain the Station Terraform module itself (not test authoring). Use this skill whenever the user asks to add, change, refactor, or troubleshoot Station module behavior in root *.tf files or child module folders (application/, group/, user_assigned_identity/, hashicorp/tfe/), update variables/outputs/validations, or adjust provider/resource wiring for module consumers.

ML pipeline orchestrator — single entry point for ML-related tasks. Coordinates ML Engineer (analysis, modeling, recommendations), SRE Engineer (production data extraction), and Product Manager (task formulation). Domain context from CLAUDE.md. MVP flow: define data requirements → extract from prod → analyze → model → recommend → feature plan.

Validates directory naming conventions for titles, assemblies, and modules. Use when restructuring content or adding new directories.

Generate comprehensive R tutorials for specialized applications (health economics, qualitative research, signal processing, environmental epidemiology) with theory + practice workflow. Use when: (1) User requests domain-specific tutorials, (2) File names match [number]-[topic].rmd pattern, (3) Keywords: TreeAge, CEA, text mining, wavelet, VMD, DLNM, WQS, BKMR.
