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

FastAPI framework with Pydantic v2 patterns, PII sanitisation, and practical workflows

Gemini Enterprise A2A configuration and rules.

Ground truth for Govee Flow Plus Light Bars (H6056): phantom segments, bar-to-segment mapping, API auth and rate limits.

Database architecture skills, docs, and rules for high-demand multi-tenant commerce platforms (PostgreSQL source of truth, Neo4j as derived GraphRAG projection, transactional outbox, RLS-based tenant isolation). Includes live schema introspection workflow via Postgres MCP.

Configures Prometheus scraping, log drains, and observability for Supabase infrastructure monitoring.

Reference tile for Themis, a Node.js and TypeScript unit test framework designed for AI coding agents. Covers unit-test authoring, Jest/Vitest migration, agent-readable failure output with repair hints, and first-class integrations for Claude Code, Cursor, and generic agents.

Injects tenant ID and RBAC permissions into JWT via Postgres Auth Hooks during token issuance.

Configures server-side session synchronization via secure HTTP-only cookies for SSR frameworks.

Rego is the declarative policy language used by Open Policy Agent (OPA). This tile covers writing and testing Rego policies for Kubernetes admission control, Terraform and infrastructure-as-code plan validation, Docker container authorization, HTTP API authorization, RBAC and role-based access control, data filtering, metadata annotations with opa inspect, and OPA policy testing with opa test.

Orchestrates long-running Edge Function work via waitUntil, pg_cron, and pgmq patterns.

Configures Postgres triggers and database webhooks for event-driven architectures in Supabase.

Secures Supabase Realtime private channels via RLS policies on the realtime.messages table.

Fuses semantic vector search with lexical full-text search using Reciprocal Rank Fusion in a PL/pgSQL RPC.

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

Enforces absolute data boundaries between tenants in shared schema via RLS policies on tenant_id.

Enforces PKCE-based OAuth code flow replacing implicit auth flows for modern Supabase auth.

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.

Automatically monitor GitHub Actions workflows after git push operations. Tracks workflow progress and reports pass/fail results.

Comprehensive documentation and best practices for building Terraform providers with terraform-plugin-framework (v1.17.0). Covers providers, resources, schemas, types, validators, testing, and common pitfalls.
