Portfolio Transmission Router
The homepage instrument validates a short text payload, matches explicit operational terms, and routes the visitor to the nearest relevant mission dossier. It runs 100% locally in your browser with zero latency, stores no telemetry, and clearly demonstrates how deterministic input contracts can guide user discovery without requiring an expensive, unpredictable LLM call.
WebMCP Client-Side Search & Schema Inspector
An in-browser WebMCP tool specification tester that parses natural-language developer queries, matching capabilities against structured tool definitions. This allows operators to test tool-calling contracts, required arguments, and JSON return types before deploying agents into production n8n workflows.
Active Research & Forthcoming Prototypes
- n8n Failure-Path Audit Engine: An automated workflow analyzer that parses exported n8n workflow JSON, flagging unhandled node failures, missing error triggers, unauthenticated webhooks, and circular retry loops.
- JSON Schema Input Contract Validator: A real-time payload validator that guarantees LLM tool calls and webhook payloads adhere to strict type specifications prior to executing sensitive API mutations.
- Sub-5ms Realtime Persistence Benchmark: A benchmark utility comparing local-first indexedDB storage against Supabase Realtime synchronization under intermittent packet loss.
Why We Build Open Experiments
At HarLyn Digital Partners, our engineering philosophy is rooted in proof over vocabulary. Building small, visible tools allows us to stress-test architectural ideas, validate edge-case latencies, and share actionable patterns with the engineering community.
