Cloudflare, AWS, Cisco, ElevenLabs, GitHub, Zoho, Claude Code, agent protocols, architecture. The deepest branch of the 2nth skill tree — the layer every other domain runs on.
Thirteen sub-categories under tech/, mirroring the canonical 2nth-ai/skills tree. Each is a branch you'll be able to walk into as explainer content lands.
ADRs, C4 diagrams, trade-off matrices, anti-pattern detection. The skill every 2nth build draws on — twelve named patterns and the honest framing of when to break them.
Full platform manifest — 16 services including Workers, Pages, D1, R2, Durable Objects, Workflows, Workers AI, Vectorize, Hyperdrive, Queues, Analytics Engine.
IAM auth model, af-south-1 region, Cloudflare+AWS hybrid patterns. Compute (Lambda, ECS, API Gateway), Security, Storage, Database, Networking, and Amazon Connect for contact centres.
MCP, A2A, ACP — the protocols that let agents discover each other, share context, and hand off work. Multi-agent orchestration patterns without the magical thinking.
IOS / NX-OS, ASA / Firepower, Meraki, Webex, Netmiko automation. Five sub-areas: networking, security, wireless, collaboration, automation.
TTS (flash/v3), voice cloning, STT, conversational AI agents. Streaming patterns through Cloudflare Workers for low-latency voice.
REST API via Octokit v21, Actions, Apps, webhooks. Copilot data policy handling as of April 2026. The substrate most 2nth builds deploy from.
CRM v8 (COQL, bulk operations), Books v3 (invoices, payments), OAuth multi-DC handling, and the CRM ↔ Books sync patterns that keep sales and finance aligned.
Claude Code setup, patterns, sub-agents, skills system, MCP servers. The CLI most of this knowledge tree itself was built with.
Model Context Protocol — servers, resources, tools, and the client patterns that turn a bundle of prompts into a programmable context surface.
Infrastructure as code — Terraform, Pulumi, OpenTofu. The declarative layer that makes Cloudflare + AWS hybrid infra reviewable and reversible.
The twin craft to architecture. Design systems, components, frameworks, motion, typography, accessibility, Figma, and AI design tools — the full frontend-design stack as eight sub-skills under one hub.
13 apps · 1 liveMetadata-driven Python framework with a thirteen-app ecosystem — ERPNext, HRMS, CRM, Helpdesk, LMS, Builder, Drive, Books, Wiki, Raven, Insights, Print Designer, and Frappe Cloud. Doctypes are the unit of everything.
Two leaves are live, more landing as content ships. Cloudflare Workers is the deepest end-to-end explainer in the tree today; the Frappe Framework is the substrate every Frappe-built business app inherits from.
Edge compute on V8 isolates, static+dynamic hosting on the same network. Nine sections covering what it is, why it matters, how it works, the ecosystem, use cases, evolution, the decision guide, how it connects, and resources.
The metadata-driven Python full-stack underneath ERPNext, HRMS, CRM, Helpdesk, LMS, and the rest of the Frappe ecosystem. Doctypes, hooks, REST + RPC, Bench, and the patterns that make every Frappe-built app coherent.
Technology touches every branch of the tree. These are the ones it pulls on most — either because tech provides the substrate (Business, Data) or because a domain has deep integration requirements back into tech (Finance, Healthcare).
