Codex CLI for Elixir and Phoenix Development: Tidewave, ElixirLS MCP, HexDocs, and Runtime-Aware Agent Workflows
Elixir occupies a unique position in the language ecosystem. Its macro-heavy metaprogramming, runtime-defined schemas, OTP supervision trees, and the BEAM's.
Codex CLI for C/C++ Development: Clangd MCP Servers, CMake Integration, and Systems Programming Agent Workflows
C and C++ codebases present unique challenges for AI coding agents: complex build systems, header dependency graphs, platform-specific preprocessor.
Codex CLI for Astro Development: Docs MCP, Agent Skills, and Edge-First Workflows on Cloudflare Workers

Agent Observability Dashboard Patterns: OpenTelemetry, Traces, and Cost Monitoring for Codex CLI
Running a single Codex CLI session is straightforward. Running dozens across a team — batch migrations, multi-agent pipelines, nightly codex exec sweeps.
Migrating from LangChain to Native Agent SDKs: A Codex CLI Perspective
By mid-2026, a quiet exodus is underway. Production teams that adopted LangChain in 2023–2024 are rewriting their agent code against vendor-native SDKs.
Codex CLI for SQLite Development: MCP Servers, Turso/libSQL, and Local-to-Edge Database Workflows
SQLite is the most deployed database engine in existence . It runs inside every smartphone, browser, and IoT device.
Codex CLI for Solidity and Smart Contract Development: Foundry MCP, Security Auditing, and Agent-Driven Contract Workflows
Smart contract development occupies a peculiar niche in software engineering: the code is immutable once deployed, bugs can drain millions in minutes.
Codex CLI for Pulumi Infrastructure-as-Code: MCP Server, Neo Delegation, and Agent-Native Workflows
Terraform dominated the infrastructure-as-code conversation for a decade, but Pulumi's bet on real programming languages — TypeScript, Python, Go, C#.
Codex CLI for Performance Profiling and Optimisation: MCP-Driven Flamegraphs, Bottleneck Analysis, and Automated Fix Loops
Performance profiling has always been a two-phase problem: first you collect data, then you interpret it. The interpretation phase — staring at flame.
Codex CLI for OCaml Development: ocaml-mcp-server, Merlin via LSP-MCP, and Type-Driven Agent Workflows
OCaml occupies a distinctive position in the programming language landscape: a strict, statically-typed functional language with a mature compiler.
