For solo builders the binding constraint is usually demand, and a useful receipt needs cost, artifact, and a user-visible before/after.

Senior engineering interviews still gate on whether you can produce a graph traversal cold in 45 minutes. A checkpoint piece, four months into the job search, on the gap between the two.

I built Context Mate as a local experiment to unify traces across Cursor, Claude Code, and Codex. So far it is only partly successful: useful for coarse Cursor buckets and Claude token curves, but not a full inventory by name, and fragile on undocumented storage.

They are hard because the server and client boundary stays invisible at runtime. This post explains why that breaks reasoning, where Next.js dev tooling already helps and where RSC observability could go deeper (dev indicator, MCP), introduces RSC Boundary as the dev overlay I ship today, and sketches a constructive extension point so ecosystem tools could register inside the Next.js dev UI instead of separate chrome.

This post maps the real problems teams face and defines what a reliable debugging workflow should provide.

Golden paths achieve the same compliance goals through self-service and opinionated defaults, and developers actually use them.

However, it is important to secure the webhook endpoint to prevent abuse.

Let's unravel this enigma, from its discovery to its resolution, with the hope that our experiences can assist others in a similar bind. Tue, 24 Oct 2023 00:00:00 GMT Valentin Prugnaud
