Context for developing and debugging Hubitat Elevation apps, drivers, and hub environment — sandbox constraints, lifecycle idioms, capability contracts, plus grounded deploy/log-tail/lint mechanisms.

Demo plugin one for scope/agent install testing

Demo plugin two for scope/agent install testing

Age gate bypass test plugin

Closing the intent-to-code chasm - specification-driven development with BDD verification chain

Provides database health diagnostics via slow query analysis, bottleneck identification, and Postgres inspection.

Prevents directory traversal in Supabase Storage via path validation functions and storage RLS.

Configures database INSERT triggers that offload document chunking and embedding to Edge Functions.

Quickstart example: Express.js API coding standards (rules)

Gemini Enterprise A2A configuration and rules.

Teaches coding agents how to build TUIs with TamboUI correctly: API-level selection, render-thread discipline, display-width safety, CSS-aware element authoring, and JFR conventions.

Ground truth for Shelly Duo GU10 RGBW smart bulb (Gen1): LAN HTTP REST contract, mDNS discovery (with the non-loopback-IPv4-bind gotcha), color/temp endpoints, off semantics, latency expectations. Language-agnostic facts; Kotlin/Ktor reference example.

Build terminal chat UIs with TUI4J - Elm Architecture chat client for AI agent demos with Spring Boot integration

Prevents silent WebSocket disconnections via Web Worker heartbeats and reconnection strategies.

Adds spec-as-source enforcement to any project using spec-driven development

Decision-Linked Development (DLD) — a workflow for recording, linking, and maintaining development decisions alongside code. Skills for planning, recording, implementing, auditing, and documenting decisions via @decision annotations.

Ground truth for Govee Flow Plus Light Bars (H6056): phantom segments, bar-to-segment mapping, API auth and rate limits. Language-agnostic facts; Kotlin/Ktor reference example.

Agent-native E2E runtime with verifiable safety. 16 MCP tools including alethia_propose_tests (agent generates tests from a URL), alethia_assert_safety (proves destructive actions are blocked), and the expect block: NLP primitive unique to Alethia. Zero-IPC; 2-5x faster than Playwright MCP per flow; signed evidence packs. Works with Claude Code, Cursor, Cline.

Run quality checks on Java code before committing. Validates against best practices, enterprise standards, and common issues.
