The system · how the work actually gets made

We didn't just adopt AI coding tools. We built a living operating system around them.

Guardrail hooks that block secret leaks and broken pushes. An independent model reviewing every diff before it ships. Cost-tiered routing so cheap tasks run on cheap models. A second brain that keeps itself current on a schedule. None of it waits to be asked — this is what actually sits behind the fixed price.

Guardrails, not vibes

Five hooks that actively block unsafe agent behavior.

Every one of these exists because it closed a real failure mode — and they block, they don't remind. Nothing here is speculative hardening.

  1. A code change
  2. The agent writes it
  3. Every push
    Five blocking gates
  4. Ships to production
  1. 01

    push-guard

    Denies any push to a protected branch if the remote moved on, or if it's a force-push. No exceptions, no --force-with-lease past main.

  2. 02

    senior-review

    Before code reaches a protected branch, an independent, stronger AI model reviews the full diff and can reject it with numbered findings — a second opinion, not a rubber stamp.

  3. 03

    secret-shield

    Scans every push — and every fresh clone — for exposed credentials, including env-var names that leak by themselves regardless of their value.

  4. 04

    quality-gate

    Refuses to let an agent end its turn with code that doesn't typecheck. A green build isn't a suggestion here — it's a requirement.

  5. 05

    env-guard

    Agents can never read a real secret value into their own context — not through the editor, not through a shell trick. Nothing they do legitimately requires it.

Any gate can say no. The change goes back to the agent — nothing reaches the main branch until all five pass.

Cost-tiered routing

Cheap tasks run on cheap models. Hard calls escalate. That's the actual token-burn optimization.

Four tiers, matched to the work — not one expensive model doing everything.

Every task
A task arrives
  1. Fast, low-cost model

    Search

    Read-only breadth search — where is X used, which files import Y — so raw file dumps never land in the expensive context window.

  2. Mid-tier model

    Mechanical work

    Fully-specified, multi-file work: renames, boilerplate, applying a spec that's already been written.

  3. Top-tier model

    Visual work

    Every non-trivial UI decision — cheaper models design poorly, so visual work never runs on anything less.

  4. On-demand senior model

    Architecture calls

    Escalation for hard judgment calls and bugs that failed twice — read-only, returns advice, not edits.

CheapestMost capable
A second brain, not a blank slate

Context survives across projects — and the knowledge base now maintains itself.

A structured, persistent knowledge base means a session never starts from zero, and a lesson paid for on one engagement doesn't get relearned on the next. It no longer waits for anyone to update it either: a scheduled agent distills every week's work into it, whether or not someone is at the keyboard. Four things get written down every time:

  1. 01
    Decisions

    what was chosen, when, and what it ruled out

  2. 02
    Clients & people

    who owns what, and what they've already told us

  3. 03
    Project state

    where an engagement actually stands today

  4. 04
    Gotchas

    the failure we already paid for once

65+ skills on tap

Best practice that fires automatically — not best practice someone has to remember.

Each skill is a scoped capability that activates itself when the work matches it. A payment endpoint pulls in the security checklist whether or not anyone thought to ask for it.

What it hands you

The machinery is ours. The output is yours.

None of the above matters unless it changes what lands in your repository. Four things it changes.

  1. 01

    An audit trail, not a chat log

    Every change arrives as a commit carrying the gate results and the review that let it through. Six months later you can still see what was decided and why.

  2. 02

    Acceptance criteria before the build

    Nothing starts without a written definition of done. If we can't agree on what finished looks like, we don't start — that's cheaper for both of us.

  3. 03

    Written handover as standard

    ADRs for the decisions, runbooks for the operations, documentation for the parts that outlive the engagement. Updates in writing, not in a status meeting.

  4. 04

    No lock-in

    Your repository, your infrastructure, your code. Nothing here runs on a proprietary runtime you'd have to keep paying us to operate.

Public evidence

Gem, our own macOS utility, is built and released on this exact setup — same fleet, same five gates, same senior sign-off. The repository is public, so its commit history is the audit trail described here.
