Building an AI agent harness in public. Working with enterprise agent-builders. Threads on what actually works in agentic systems.

I'm building motors & sensors in public — an open-source, local-first harness that makes your coding agent get better the more you use it. Not a new agent; a layer on the one you already run (Claude Code / Codex / Gemini). How it works 🧵

robotics for personal / casual consumption is sooner than it appears.

wait for chatgpt moment or build it?

Today I'm publishing a new essay, Policy on the AI Exponential. AI is progressing extremely fast—much faster than the policy process was built to handle. The essay lays out where I think the technology is now, and the action needed to close the gap: https://t.co/Lh6PWae178

Is SF that good? It most probably is.

I feel so left out and given the 100K entry lot - it's so difficult to even start the plan for SF dream.

Maybe maybe not..

harness diary · day 2 — motors & sensors

yesterday: 4 hosts traced. today: made it installable.
→ npm i -g motorsandsensors — zero deps, 33 kB
→ mns init scaffolds your agent's faculty home (.mns/) — works like git init
→ repo went professional: 4 living docs, one build journal, one test home
→ publishing is now token-free (npm OIDC trusted publishing) + provenance-attested and the pipeline earned its keep in hour one: first CI run caught a Linux bug my mac was hiding. 0.1.1 shipped the same hour.

lesson: the registry + CI find what your laptop hides.

harness diary · day 1 — motors & sensors

this morning: design docs, zero code. tonight: pushed to github: https://t.co/VtwYzwGkQb

→ host-agnostic trace capture (OpenTelemetry): any coding-agent session
→ a trace you own
→ mns, a git-native CLI — enable once, capture goes invisible
→ 4 hosts, all verified on REAL sessions: Claude Code · Gemini · Codex · OpenCode

the bet: wrap the agent you already run, never drive it. one tiny adapter per host, zero changes to the core — proved it 4×.

biggest lesson (full thread Thursday): the vendor docs lied twice. build adapters from real wire
data, not docs.

I'm using it for a personal project on agent harness shell around terminal agents (codex, cc, gemini, opencode)

And it's local-first — the whole thing runs on your machine, nothing leaves by default. Open source from commit zero. I'll post the wins, the dead-ends, and the learnings here as I build. Follow along 👇

The twist: these faculties graduate. It watches your real runs (the sensors), scores how each one performed, and proposes upgrades — a sharper tool, a promoted memory, a tighter guardrail. You approve. It pins a new generation. Rollback = flip a pointer.

is vibe really a new concept? - This made me think otherwise.

[aj @ajlkn]

Vibes are what separate us from the machines

The biggest problem with @AnthropicAI Claude Desktop is the 'Chat window' limit.

"Please start a new chat" FML!

[Harshit Choudhary @h1902y]

@im_roy_lee seriously?

no 'cheat-coder' or 'vibe-coder' or even 'vibe-operator' (non-engineer) role.

I'm building an open-source tool for same - https://t.co/WTNgxEnkPn

hire me on trial and fire me if you don't see value - [email protected] or twitter dm.

In a future where a lot more can be done by AI agents, here is how the future of work could look like:

At 1:45 AM last night, a heinous crime took place on our campus. 2 of our students were physically and sexually molested by 3 goons on motorbike. This is not isolated incident, and it's time for change.

@1108King sounds like an interesting read to me.

else do 'pain by pain'
