What changed and why it matters to you

Four articles completing the developer production path: deploying to production (secrets, rate limits, cost controls, observability checklist), production error handling (API error taxonomy, output format resilience, hallucination detection, user-facing errors), end-to-end Next.js + Claude chatbot (streaming SSE, Vercel deploy, conversation history), and what to actually build with Claude as a first product (the 2x2, structural advantages, the test before you build).

Four new articles: prompt caching implementation (cache_control, multi-block caching, verifying hits, 80% cost reduction patterns), cutting Claude API costs (model routing, batch API, output length control, context management), building a chatbot with persistent memory (user facts, session summaries, extraction patterns), and using Claude for note-taking and knowledge management (Projects, capture workflows, retrieval patterns).

Four articles completing the developer and founder content: tool use implementation deep dive (defining tools, parsing responses, parallel tool calls, production failure modes), multi-agent orchestration basics (orchestrator + subagents, parallelism, state management, checkpoints), customer discovery with Claude (interview simulation, assumption mapping, synthesis), and meeting prep patterns.

An 8-step implementation path for developers: API basics, streaming, RAG pipelines, tool use, evals in CI, prompt caching, and agentic loops. Assumes you can code — no business-case framing. Visually distinct from the operator paths.

Four technical articles: your first Claude API call (auth, streaming, structured output, errors), building a RAG pipeline from scratch (chunking strategy, hybrid retrieval, reranking, evals), writing evals that catch regressions (test case structure, LLM-as-judge, CI integration), and streaming implementation patterns (SSE to browser, error handling, UX).

A 7-step path for solo founders and early-stage builders: validate your idea, choose the right stack, avoid the failure modes, price your product, get your first ten customers, and pitch to investors. No ML background required.

Seven new articles targeting the zero-person startup: the solo founder operating system, idea validation without fooling yourself, build/buy/prompt stack decisions, AI product failure modes, investor pitch narrative, pricing your AI product, and getting your first ten customers.

Four new articles: how to give Claude precise connector instructions (the difference between "find that doc" and an instruction that reliably works), managing email with Claude, the 20-minute weekly review, and using Claude to declutter your digital life.

A 10-step path for IT leads and administrators: from evaluating Claude to running it across an organisation. Three stages — evaluation, deployment, ongoing management — each with dedicated articles.

20 Claude features grouped by capability area — core interface, skills & connections, automation & agents, research & intelligence, admin & scale. Each with a definition and a guide.

A full batch of operator-focused articles covering: admin setup, plan selection, org-wide Projects architecture, usage policy, system prompt writing, role-type field notes (finance, product, legal, data, engineering, executives), change management, token control, security, and more.

Practical, role-specific articles covering what AI actually looks like for each function — what works, what doesn't, and how to set up Claude for that team.

Two structured paths: "Figuring out AI for your company" for founders and ops leaders, and "Getting your team actually using AI" for department heads. Each walks through the key decisions in order.

Glossary terms for all major Claude features: Projects, Skills, Connectors, Artifacts, Memory, Cowork, Dispatch, Deep Research, Computer Use, Managed Agents, Claude Plans, Claude Code, MCP, and more.

AI Codex launched with a glossary, articles, and the first learning path. Built for operators and admins implementing Claude at work — plain-English explanations, practical guides, no hype.
