The Agent Development Lifecycle (ADLC): A Practical Guide

The Agent Development Lifecycle (ADLC): the eval-driven methodology for building reliable AI agents, run in five stages: Build, Evaluate, Deploy, Monitor, Diagnose.

What a Good Evaluator Agent Actually Does

A plain guide to evaluator agents: read the whole trace, apply the right standard, cite evidence, and return a useful verdict.

Agent DNA: what your agent inherits, or rebuilds from scratch every time

Every failure your agent hits should compound into a permanent, model-agnostic layer. Agent DNA is the spec, the dataset, and the evaluation sets, together: the place where agents keep what they learn.

Your whole loop rides on one number

A score only drives the loop if you can trust it. How the Evaluator's judge keeps a score honest: an independent grader, checks not ratings, binding every term to the trace, proving the claim entails the verdict, calibration against experts, and a noise floor it measures instead of hiding.

Meet the Agentic AI Engineer

Building agents by hand keeps you inside the loop. Vibe-automating it with a coding agent or buying an observability platform does not get you out. The Agentic AI Engineer is the Agent Development Lifecycle, run agentic.

Eval systems are grown, not authored: meet the Evaluator agent

How the Evaluator agent turns production traces and domain knowledge into a living eval system: eval-from-traces, calibrated anchored rubrics, reliable pass/total scoring, and the judgement boundary it refuses to cross.

Diagnose before you mutate: how the diagnostics agent reads your traces

How the Mutagent diagnostics agent turns a pile of agent traces into ranked root causes: a static cost gate, signal census, trace segmentation, a capped fan-out of analyzers, recursive root-cause analysis, and a three-axis failure taxonomy.

Three AI debts compound. The artifact mindset is why.

A recent VentureBeat piece named the right symptoms in enterprise AI: prompt debt, retrieval debt, evaluation debt. The cause sits one layer down, in how teams still treat agents as artifacts to ship instead of systems to evolve.

Eval-Driven Development: reliable scoring when the judge has opinions

A methodology for reliable scoring on prompt-based AI features, when you can't write criteria upfront and the LLM judge keeps disagreeing with itself.

Year zero of the autonomous AI agent engineer

Building an AI agent is 20% of the work. The other 80% is the engineer's full-time job. The autonomous AI agent engineer is the next layer of the stack.

The AI engineering ladder

How the AI agent market really sorts: not by tool category but by operator maturity stage. The four stages every AI team climbs, drawn from 20 interviews and 4,129 pain quotes.

The variance floor of LLM-as-judge: what it does to your optimizer

A controlled replication study of three prompt optimizers on FinanceQA 150. The 5.46pp LLM-judge variance floor, and how it shapes acceptance-gate behavior.

What 4,129 community pain quotes tell us about AI agent reliability

AI agent reliability is an eval problem. We coded 4,129 community pain quotes from 13,400 forum posts spanning April 2025 to April 2026. Here is the methodology behind that finding (calibration, inductive coding, source de-biasing) and the data. Total AI spend on the pipeline: under $50.

Your Agent on Day One Is Just a Guess

Every AI agent starts with assumptions baked in. The real challenge isn't building the first version — it's what happens after it meets the world. Learn how Mutagent closes the improvement gap automatically.

From Software Factories to Agent Factories: When Agents Build Agents

Software factories prove agents can ship production code. The same loop pattern applies to optimizing any agent. Here's why static eval criteria fail, why scenarios succeed, and how continuous optimization compounds over time.
