Curated tools, articles and essays for AI-First leaders.
The Capiva library is a curated collection of guides, essays, tools, and articles on AI applied to business — from AI harness and context engineering to GEO/AEO (AI visibility) and AI Centers of Excellence. Use the filters below to jump straight to the type of content you need.
AI consulting for businesses covers diagnosis, proof of concept, implementation, and ongoing governance. What each track includes, how to evaluate a vendor before hiring, and what separates a good engagement from a bad one.
GEO (Generative Engine Optimization), AEO, and "SEO for AI" are the discipline of optimizing content to be cited by AI answers — distinct from classic SEO, which ranks links. The concept (Princeton, 2023), the difference between the terms, and what the AI rewards.
You don't register your company with ChatGPT — the AI recommends whoever has a citable, structured, authoritative presence. The three real levers (citability, authority, technical access) and how to test.
ChatGPT has no company registry: no form, no directory. The AI recommends whoever already has a citable presence on the web. Why registration does not exist and what to do instead.
An AI Center of Excellence is the internal structure that drives AI adoption to valuable outcomes and prevents fragmented or ungoverned adoption (Microsoft CAF). Most fail by becoming bottlenecks.
There is no fixed price table for AI consulting. The value depends on the billing model (hourly, project, retainer, scope), the seniority of the team, and the actual scope of the problem. The factors and the right questions to ask before accepting a quote.
An AI harness is the infrastructure around an LLM (tools, rules, memory and quality gates) that turns it into a reliable agent. Agent = Model + Harness.
"Harness" means a bridle, safety harness, or (as a verb) to control or make use of, and it became a technical term: harness.io (CI/CD), wiring harness, and AI harness. Here is each sense.
Harness engineering is the discipline of designing everything around the model (rules, tools, memory, and verification) so an agent works in production. Named by Mitchell Hashimoto in 2026.
An agent framework is a library you build with; the harness is all the code, configuration, and execution logic that isn't the model. They aren't synonyms.
Context engineering is one layer of the harness, not a synonym, and RAG is one technique inside context engineering. Understand the containment: RAG inside context engineering, inside the harness.
Real examples of an AI harness: Claude Code, Cursor, Devin, LangChain's deepagents-cli, and capivaOS, a harness engineered on top of Claude Code.
To build an AI harness, start simple and grow it from observed failures: each agent error becomes a permanent rule, then systematized into guides and sensors.
Claude Code is a harness: CLAUDE.md, hooks, MCP, subagents, and permissions are the guides and sensors around the model, and capivaOS is a harness engineered on top of it.
In agent benchmarks, the harness moves the score as much as the model. There are two senses: agent harness (the scaffold, which must be disclosed) and eval harness (the runner, which must be held constant).
The operational harness is harness engineering applied to running an entire business, not just code. The biggest AI ROI sits in the back office, per MIT, and almost no one has built this layer yet.
Capiva built an operational AI Harness and open-sourced its development layer as capivaOS. What harness engineering is and how it works in practice.
The first Brazilian edition of the Claude Impact Lab brought teams together in Rio to build AI solutions for public health and public safety.
Capiva built an AI visibility diagnostic tool and tested it on its own site. See what AEO reveals about most websites.
capivaOS: open-source (MIT) harness that enforces a spec → plan → implement → verify pipeline on Claude Code, with mechanical quality gates. Plugin, 2 commands.
