Prompt systems
Pattern libraries, system prompts, and modular prompt chains that are easier to maintain, test, and improve.
Hey. I’m Sunil,
I help organizations turn generative AI from an interesting experiment into something dependable, useful, and ready for production.

Pattern libraries, system prompts, and modular prompt chains that are easier to maintain, test, and improve.
Task decomposition, tool-use orchestration, and guardrails so multi-step work completes more reliably.
Quality gates, golden sets, rubric scoring, and audit trails before systems fail in production.
Playbooks, roles, review loops, and working methods that turn isolated experiments into repeatable capability.
Blended strategy and implementation: prompt systems, agents, evaluation, and the operating model that makes generative AI durable in production.
Education & research
The education and research brand for practical AI literacy: prompt systems, production agentic workflows, and the frameworks teams can actually run. Libraries cover Partials, Agents, and Miniscripts. The site reaches 20k+ subscribers.

Aim, Coordinate, Execute — split intent, routing, and deterministic work so automations stay testable.
5C
Clarity, Contextualization, Command, Chaining, Continuous Refinement — a prompt-construction loop.
PseudoLangs
Constructed notations between prose and code, so encoding — not just wording — carries the load.
01
The systematic design, refinement, and evaluation of prompts and the structures around them — not just clever phrasing.
Read on site02
How agents plan, act, and verify: when they beat static automations, and how structured outputs and guardrails make them production-ready.
Read on site03
Aim defines the business intent, Coordinate decides who runs next, Execute does the work with scripts and tools you can test.
Read on site04
Purpose-built notations for talking to models. How you encode a prompt — not only what it says — changes the result.

The discipline
Less hype. More working systems. The site covers the design, tooling, evals, failure modes, and operating practice behind AI agents that have to survive real work. Read foundations first, then mechanics, then AgentOps.
Visit AgentEngineering.orgFoundations
What an agent is, what changes from a plain LLM, and how much autonomy a task actually needs.
Mechanics
How systems decompose work, take action with tools, remember, and reason through multi-step runs.
AgentOps
Traces, evaluations, guardrails, and human controls as an ongoing production practice.
01
The discipline of designing, building, evaluating, and operating goal-directed AI systems that reason over state, use tools, and act under explicit control.
Read on site02
Goal-directed software that uses models, tools, context, and control loops across multiple steps — without the hype.
Read on site03
The operating layer that turns traces, evaluations, guardrails, and human controls into a practice for live autonomous systems.
Read on site04
Structured outputs constrain shape, guardrails constrain policy, and execution boundaries constrain power. Safe agents need all three.
