AI coding agents specialist: Claude Code, Codex and vibe coding that holds up in production
I set up AI coding agents for engineering teams so the code they write can be trusted.
Anastasiia Butova, ML engineer in Belgrade, Serbia. I build image-processing software with Claude Code
and Codex every day, and I open-sourced the tooling that made that work in a team: rulebooks the
agents follow, hooks that enforce them, coordination between parallel sessions, and a check that
stops an agent from saying "done" while two languages disagree. Open to contract work and
consulting next to my main line, ComfyUI and image-processing pipelines.
What a team gets
- An audit of how agents work on your codebase. Where they guess, where a green test hides a
broken seam, which instructions they ignore under a long context.
- Rules that hold. CLAUDE.md and AGENTS.md written for the codebase, and the hooks that make the
important ones mechanical: a rule in a prompt is advice, a hook is a gate.
- Seams that are checked. Crossweft maps the hand-written contracts
between Go, TypeScript and Python (an API version, a DTO field, an env var) and fails the change when
one side moves alone.
- Parallel sessions without collisions. mclaude: locks, handoffs and a
mailbox for several Claude Code sessions on one repository.
- Vibe coding with a floor. Prototype fast, but nothing ships on the agent's word: each change
carries a test or a runtime check, and an independent review for anything irreversible.
Evidence
- codex-claude-code-config - 30 architectural principles, 58 skills
and 40+ safety hooks for Claude Code and Codex; MIT, 150★ and 24 forks on
GitHub.
- Crossweft - open-source cross-language contract check with an MCP server,
agent hooks and a GitHub Action (source).
- mclaude - file-based coordination for parallel Claude Code sessions, 193 tests.
- Price index - agent-run market pricing for a jewellery wholesaler: four
agent lanes with explicit allow and forbid lists, where no agent may write a price and only
deterministic validators do.
- Glam.ai - built the multi-agent coordination system the engineering team used,
an AI knowledge base (550+ articles) and pre-configured VMs with AI tooling for engineers.
- happyin.space - 1,287+ reference articles structured for agents to
retrieve from.
Writing on agents
Questions
Can you set up Claude Code or Codex for our team? Yes: an audit of the codebase and how the
team uses agents, then the rulebook, the hooks and the checks, handed over in your repository.
Is vibe-coded code safe to ship? Not on the agent's word. It becomes shippable when every change
is verified by something other than the agent that wrote it: a test that fails without the change, a
runtime check, a contract check across languages.
Do you work remotely? Yes, from Belgrade (CET), in English, Russian or Serbian.
