Defines a generic Linter interface and a ShellBasedLinter base class that wraps any CLI linter (ESLint, Pylint, Hadolint, etc.) by running a shell command and parsing its output with regex. The framework provides 19+ concrete linter implementations, each with its own regex-based output parser. This pattern is reusable in any project needing to integrate multiple static analysis tools: just add a new class extending ShellBasedLinter and provide the command and parser. The design is clean, testable, and platform-agnostic (shared across JVM and JS).

Implements a composite scoring model that combines multiple scorers (BM25, TypeScorer, NameMatchScorer, RRF, etc.) with configurable weights. The scorers are independent and can be extracted into any search/ranking system. The CompositeScorer aggregates scores and reranks results. This is a clean, reusable pattern for multi-criteria relevance scoring in search or code retrieval tasks.

Provides a complete parser and renderer for NanoDSL, a spec-driven UI definition language that allows agents to declare UI components (VStack, HStack, Card, Button, etc.) with two-way binding. The DSL is parsed into an intermediate representation (NanoIR) and rendered to platform-specific UI (Compose, React, etc.). This component is self-contained and could be extracted to any project needing dynamic UI generation from AI output, demonstrating non-obvious skill in designing a concise, extensible declarative UI format.

Implements an extensible tool registry where providers (BuiltinToolsProvider, McpToolAdapter, etc.) register themselves with a priority. The registry supports lookup by name, type, and bulk retrieval. This pattern is reusable for any plugin-based system needing dynamic tool discovery. The design uses a clean registry pattern with provider abstraction, avoiding tight coupling to specific tool implementations.
