Agentic Loops

Tokens are the new developer currency. Scroll down to get started.

The New TDD

What is the new TDD?

Token-Driven Development

Tokens = currency

Your input is now in tokens, not hours.

Maximise impact

Generate more value per token invested.

2x-10x leverage

One engineer, amplified through agents.

The Spec-Driven Framework

Spec-Driven Agentic Loop

A1

Spec

Structured spec → docs/specs/ Prior art research

model: sonnet

A2

Architect

HLD + LLD + Data Flow diagrams Multiple approaches

agent: architect model: opus

A3

Orchestrate + Implement

Orchestrator → decides which tasks can be done serially vs parallely, generates Linear/Jira issue & sub issues Feature builder → builds feature layer by layer

agents: orchestrator, feature-builder model: sonnet

A4

Verify

Task marked as done → build + lint + test all pass If any of them fail → agent makes changes and verifies again and this loop keeps going until the output is right

agents: test-writer, code-reviewer model: sonnet

Each phase = dedicated sub-agent  ·  specialist model  ·  domain-specific rules

Changing landscape

What do you think about the following statement?

“Coding is largely solved.”— Boris Cherny

It's natural to feel scared.

That reaction is understandable — and worth sitting with.

We are software engineers.

Requirements, arch, tests, monitoring — coding is one part.

Let's build.
