Running Claude Code in Production: What Worked
A developer describes three weeks of running Claude Code on a production bilingual booking bot (Telegram + WhatsApp, Postgres, Google Calendar). Practical configuration that proved valuable included a repo-root CLAUDE.md that captures project rules grown from failures, two custom agents (notably a 'code-reviewer'), one checklist-style skill (/add-feature), and two lightweight hooks (blocking edits to secrets and running typechecks after edits). The setup took about two hours total and materially reduced defects, caught a midnight edge case before users did, and cut the frequency of “it said done but nothing compiles” incidents to about zero.
Practical, reproducible guidance for running LLM-based developer tooling in production; useful to engineering teams adopting agent workflows but not industry-shifting.

Key Takeaways & Evidence Grounding
- The author ran Claude Code for three weeks on a bilingual booking bot integrating Telegram, WhatsApp, Postgres, and Google Calendar.
- The production setup that proved useful comprised a CLAUDE.md file, two custom agents, one reusable skill (/add-feature), and two hooks.
- A custom 'code-reviewer' agent (tools: Read, Grep, Glob, Bash) enforces correctness, security checks, and CLAUDE.md rules and caught bugs including a midnight booking bug and an unvalidated webhook input.
- Hooks implemented: a PreToolUse hook that prevents edits to secrets files, and a PostToolUse hook that runs the project's typecheck after every file edit and feeds errors back into the session.
- The author reports the full setup took about two hours spread over days and materially improved shipping velocity and code quality.

Using Claude Code in Full‑Stack Development Workflow
An individual full‑stack engineer describes five months of daily use of Claude Code (alongside Gemini AI and GitHub Copilot) to accelerate full‑stack SaaS development. The author reports building six production applications with an 87% implementation acceleration, ~80%+ test coverage, and no critical production issues from AI‑generated code after human review. The post outlines a four‑phase workflow (architecture & design; server‑side implementation; frontend implementation; testing & security), lists high‑ROI tasks for the AI (boilerplate, error handling, database optimization, security review, documentation), and describes areas where the agent struggles (business logic, custom integrations, performance profiling, architectural trade‑offs). The author emphasizes mandatory human review, testing, staging, canary rollouts, and feature flags before production deployment.
Claude Code Transforms Freelance Developer Workflow
A freelance developer describes running seven Claude Code agents across 16 projects on a single machine, coordinating them without external frameworks by using file-based inboxes, simple shell scripts, and Claude Code’s hook system. The post details a minimal message bus implemented in ~/.claude/bus (inbox files, send.sh, broadcast.sh, audit.log, check-inbox.sh), hook-driven lifecycle scripts (SessionStart, UserPromptSubmit, PreToolUse, PreCompact) and a shared error database that propagates operational knowledge between agents. The system manages real workloads—crypto trading, marketing pipelines, a multiplayer game server and home automation—and has run in production for three months. The article is a technical how-to and case study that explains architecture, example scripts, failure modes (latency, concurrent edits, tightly coupled workflows) and step-by-step instructions to reproduce a two-agent setup.
Running a Claude Code Agent in Production
A developer describes operating a Claude Code agent named Koda as a 24/7 daemon on a MacBook Pro for two weeks, performing scheduled work (posting to X and Bluesky, drafting blog posts, syncing Skool to Airtable, analyzing YouTube, and publishing via Discord approval). The architecture prioritizes a thin runtime (pm2 + cron) and a filesystem-first state under ~/.koda/ (soul.md, skills, scripts, tasks.json, data/), avoiding vector DBs or orchestration layers. The post documents production failures (context/token limits, silent config inheritance via SDK settingSources, sub-task turn caps, expired cookies) and operational fixes, plus a self-healing diagnostic skill that restarts processes, classifies errors, applies fixes, verifies health, and reports to Discord. Cost and rate-limit realities are covered: Koda runs on a Claude Max subscription with no additional per-token billing but is subject to daily rate limits; occasional Gemini API calls incur small variable costs.
