Your harness makes a hundred small judgements a turn. Jev makes them typed.

Jev does not generate text. You hand it a state and a map of typed questions, and it hands back typed answers with calibrated probabilities, every …

Agents made code cheap. Simple, fast, correct software still costs what it always did.

The claim that software engineering dies with agents is a sci-fi plot, not a forecast. What is happening instead looks familiar: a new abstraction …

A $45B fund was long the AI bottleneck at 400% leverage. We built an agent that finds the bottleneck and refuses the leverage.

On July 31 the Situational Awareness fund was forced to sell its leveraged book, SK Hynix and CoreWeave among the names, and fell from $45 billion to …

RAG works on one PDF. Production hands you eleven thousand.

Every retrieval tutorial ends at the moment the hard part begins: a corpus you did not curate, a thousand users you did not simulate, and no way to …

MCP versus APIs is the wrong fight. Both sides want the same layer.

Harness as a Service sells you the box. The harness is the verifier.

A new category is forming around agent runtimes, sandboxes and microVMs, and the word every pitch leans on is harness. The isolation is real and …

Skip the Agentic AI course. Build the harness first.

Every agent framework you will ever use is a variation on a loop you can write yourself in an afternoon. Here is the order I would learn things in …

The best case for agentic coding is the software you build only for yourself.

The standard objection to agent-written code is security, and it is correct for anything networked and multi-tenant. It mostly evaporates for a local …

Spec-driven development is not a silver bullet. It is the new Scrum.

Writing the requirements down before the agent starts is a real upgrade over vibe coding. It is also a process, not a solution. The spec is prose, …

Agents can finally squash decades of technical debt, if you stop treating the old code as the source of truth.

Agentic coding is at its best inside a legacy system: rewrite a service into a better technology fit, swap the database engine, carve up the monolith …
