AI is a calculator. You still own the code.

How I actually use AI to build: the mindset, the tips and hacks I use day to day, and the opinions about MCP, skills, autonomy, and shipping that I will argue with you about.

I built my own dictation app instead of renting one

Why I built Quill, a local-first voice dictation app: on-device Whisper and embedded llama.cpp polish, full privacy, free, with cloud sync and models reserved for Pro.

I love Claude Code. I built my own runner anyway.

Why CorvidLabs runs Merlin and Ollama day to day and keeps Claude Code and Codex for contract work: ownership, any provider, and a runner built on our own tools.

I wanted a confidence rating without asking an AI

augur scores the risk of a diff with no LLM: eight signals from git and the filesystem, one score, one verdict. A deterministic baseline a human or an AI can tune.

One command for every project

fledge is the dev CLI I wanted: one gate across every language, a tiny core, a sandboxed plugin protocol, and no AI required, which is exactly why an agent can use it too.

I wanted my specs checked both ways, so I built spec-sync

spec-sync is my own take on spec-driven development: a CLI that checks spec and code against each other in both directions and fails CI when they drift.

Who reviewed this commit, and how sure were they?

attest records who or what reviewed each commit, at what confidence, signed and stored in git notes. It captures the augur verdict and gates the merge on a policy.

Building a flock in the open

Why CorvidLabs ships a family of small, sharp dev tools that feed each other, and why we are writing about it here.

Why agents want a CLI, not an MCP

Why the command line is the interface I build for AI agents in development, and where MCP and skills actually belong.

Stop meeting, start building

AI made building cheap, so the excuse to sit in meetings instead of shipping is gone.

Give the agent its own VM

Where you let an autonomous AI agent run matters more than what you let it do, and isolation is what buys you the freedom to give it real autonomy.

A conversation is a path

How I steer an AI session by treating the conversation as a path: retrace wrong turns, keep steering instead of restarting, and fan out once the context is rich.

Getting an AI up to speed

Getting good output from an AI is mostly an onboarding problem, so here is how I build context and set the target before it does any real work.

Trusting code I didn't read

How I trust AI-written code I never read line by line, using confidence ratings and a stack of cheap verification signals.
