Requires detailed type annotations for all Python functions, methods, and class members.
Generate code to assign cell type labels to single-cell RNA-seq clusters using CellTypist, SingleR, marker-based annotation, or reference label transfer (scANVI/ingest). Triggers on requests to "annotate cell types", "label clusters", "run CellTypist", "SingleR annotation", "marker gene dotplot", "transfer labels from reference atlas", "cell identity", "automated annotation", "reference mapping", "scANVI label transfer", "canonical markers", "immune cell types", "hierarchical annotation", "majority voting CellTypist", "over-clustering annotation".
Use when converting an existing JavaScript Lightning Web Component (.js, .html, .css) to TypeScript with full type annotations and a matching `.d.ts` file that exposes only the component's `@api` surface. TRIGGER when the user says "convert LWC to TypeScript", "migrate LWC to TS", "rename .js to .ts for this component", "add types to my LWC", "generate .d.ts for this LWC", "type-annotate @api properties", or "produce declare module 'c/componentName' definitions". DO NOT TRIGGER when the user is authoring a brand-new LWC from scratch (use experience-lwc-generate), generating Jest tests for an existing LWC (use experience-lwc-generate), or migrating an Aura component to LWC.
Use when experimenting with TypeScript. Use when migrating JavaScript gradually. Use when adding types to JS files. Use when teams are learning TypeScript. Use when validating JavaScript with types.
Python type checking expertise using ty - the extremely fast type checker by Astral. Use when: (1) Adding type annotations to Python code, (2) Fixing type errors reported by ty, (3) Migrating from mypy/pyright to ty, (4) Configuring ty for projects, (5) Understanding advanced type patterns (generics, protocols, intersection types), (6) Setting up ty in editors (VS Code, Cursor, Neovim, PyCharm).
Migrate a file to use stricter Pyrefly type checking with annotations required for all functions, classes, and attributes.
Fix PHPStan static analysis errors by adding type annotations and PHPDocs. Use when encountering PHPStan errors, type mismatches, missing type hints, or static analysis failures. Never ignores errors without user approval.
Use when writing type annotations on variables. Use when TypeScript can infer the type. Use when code feels cluttered with types.
Systematic resolution of pyright/mypy type errors with categorization and fix templates. Use when pyright fails, type errors are reported, adding type annotations, or enforcing type safety. Analyzes Python type errors, categorizes them (missing annotations, incorrect types, generic issues, Optional/None handling), and applies fix patterns. Works with .py files and pyright output.
Interactively fix any type checking issues in Python code
Luau type system: annotations, generics, narrowing, inference philosophy, sealed/unsealed tables, exports, and Roblox-aware typing.
Expert Python developer specializing in Python 3.11+ features, type annotations, and async programming patterns. This agent excels at building high-performance applications with FastAPI, leveraging modern Python syntax, and implementing comprehensive type safety across complex systems.
