Help your team write AI-assisted code the way a senior team would.

Most teams adopt Cursor, Copilot, and Claude Code months before they adopt the review habits, repo instructions, and CI gates that should sit around them. Post Code Labs works alongside your developers to put those pieces in place — on real pull requests in the repository you are already shipping from.

What an engagement actually changes

Six concrete things we put in place. None of them are deliverables we hand over and walk away from.

01 · Constitution

A project constitution your agents read

An AGENTS.md (with CLAUDE.md or .cursor/rules bridges) naming architecture boundaries, source-of-truth files, forbidden patterns, and verification commands.

02 · Review

Review heuristics your team can apply themselves

We pair on the next handful of pull requests, name the heuristics out loud, and leave the checklist your developers will keep using.

03 · CI

A CI pipeline that is authoritative, not decorative

Install from the lockfile, typecheck, lint, tests, build, and migration validation — required on the merge path.

04 · Release

Branch protection and a release path you can describe

A default branch nobody pushes to directly, short-lived feature branches, preview deploys, and a release habit the team owns.

05 · Tests

Regression tests around the workflows worth protecting

Unit tests on the domain logic where an AI rewrite would hurt most, one integration test on the critical path, and a smoke test against a preview.

06 · Cadence

Working sessions on the real backlog

Two sessions a week on tickets the team would have shipped anyway, with asynchronous pull request review in between.

Once shipping is no longer the bottleneck, the same three doubts show up

After the first few months of agent-assisted work, the harder problems rarely come from the agent. They come from the workflow around it.

Review is the part we are least sure about

Reading an agent's diff is a different skill than reading a colleague's

Type drift, missed validation, duplicated logic, schema and code disagreements, stale agent instructions — a handful of patterns show up over and over. A short checklist catches most of them.

The same bugs keep coming back

When an agent reintroduces the same mistake, the prompt is rarely the right place to fix it

Recurring agent bugs are usually missing context, not missing instructions. The fix lives in types, lint rules, regression tests, and AGENTS.md — not in a longer prompt.

Nothing in the release path is blocking a bad change

There is plenty of automation. None of it is stopping a broken change from reaching production

A required merge path with install, typecheck, lint, tests, build, and migration validation — plus removing the silent paths that push to production from cron jobs or scripts on a server.

What the first month usually looks like

Most engagements run on roughly this shape. We adapt it to what the team is actually shipping.

Week 1

Read the repo, pair on real changes

  • Review the open pull requests with the team
  • Walk the architecture together
  • Ship a first AGENTS.md and a draft CI pipeline

Weeks 2 to 3

Wire the gates, do the work together

  • Required CI checks live, branch protection on
  • Pair on the next handful of pull requests
  • First regression tests on the riskiest workflows
  • A written review checklist, committed to the repo

Week 4 and onward

Hand it back

  • The team runs the workflow without us
  • Fortnightly review, ADRs, agent-instruction updates
  • We stop when the cadence is no longer adding much

Frequently asked questions

Practical answers for teams thinking about bringing us in.

    • Will you write code for us, or just teach us?

      Both, in practice. We write code with the team on real pull requests in the same repository, and the lessons from that work go into the review checklist, the CI gates, and the agent instructions the team keeps. There is no parallel sprint of contractor code that gets thrown over a wall at the end.

    • How long is a typical engagement?

      Four to six weeks of active work, then a lighter fortnightly cadence for as long as it is useful. We try not to overstay. The engagement is working when the team can run the same cadence without us.

    • What is in the team's hands at the end?

      A committed AGENTS.md and any tool-specific bridges, a CI pipeline that is required on merge, branch protection on the default branch, a regression suite around the riskiest workflows, and a review checklist your developers actually use. The artifacts live in your repo, not in our notes.
