judgment-free checklist (not really)

Does your team use Harness, Spec Driven and OpenSpec โ€” or just repost AI memes?

Be honest. A quick test to see if your company structured its agents or still runs in 'paste into ChatGPT and pray' mode.

At your company, today:

01

Harness

The agent's life jacket

Skills, rules, MCPs and organized context โ€” so AI stops inventing endpoints, tables and business rules nobody asked for.

๐Ÿšจ Classic sign: dev says 'just make it work' and hopes production survives Friday.

02

Spec Driven Development

Spec before code. Groundbreaking, I know.

What first, how second. Fewer review surprises, fewer 'oh but I imagined something else' mid-sprint.

๐Ÿšจ Classic sign: user story with three words, a rocket emoji and zero acceptance criteria.

03

OpenSpec

Open contract between PO, dev and agent

Readable, versioned, living specs โ€” business understands, engineering executes, agent doesn't hallucinate new requirements.

๐Ÿšจ Classic sign: PO sends a 4-minute voice note and the agent interprets it as a Rust microservice.

maturity level

Pick the cards above. No pressure โ€” your Slack already has enough messages.

Whether you scored 0% or 100%, the next step is the same: structure.

Full-time hire

I embed in your team and make it work

For companies that need someone in the trenches: building harness, running Spec Driven and OpenSpec daily, and accelerating real delivery โ€” not just shiny pilots.

  • Full harness: skills, rules, MCPs and context on your real stack
  • Squads shipping faster with less rework and fewer agent hallucinations
  • Spec Driven and OpenSpec as routine, not kickoff slides
  • Knowledge transfer: your team levels up, not stays dependent

Consulting

Surgical consulting, results on a timeline

For companies that want a fixed scope: assessment, roadmap and ready-to-use playbooks so your team keeps going with confidence.

  • Maturity assessment and gap map (you already started here)
  • 30/60/90-day harness roadmap prioritized by impact
  • Skills, rules and templates ready for your product domain
  • Hands-on workshops with tech leads and devs for real adoption
I want consulting

โ€œA well-built harness is not big-tech luxury.
It separates teams that use AI from teams that lose sprints.โ€
