Making AI agents reliable.
One article per way an agent actually gets stuck, and what makes it stop happening.
How to Know When an AI Agent Has Hit a Wall and Needs a Human, Instead of Retrying Forever
Retry loops are the most expensive failure an agent has. Here are the five signals that an agent is stuck on something it cannot solve, the budget that ends the loop, and what to do at the wall.
"Session ended", "did not respond in time", "invalid handoff request": What Agent Session Errors Mean
The three error messages people search when an agent run dies mid-task, what each one actually means, and the two fixes that cover all of them.
Observability vs an Authority Layer for AI Agents: What Each One Catches
Observability tools such as Langfuse, LangSmith and Arize Phoenix tell you an agent broke and why. An authority layer is what lets a person step in with permission and turns that intervention into a procedure the fleet reuses. You need both; they answer different questions.
What Is an Authority Layer for AI Agents?
An authority layer is the system through which an AI agent borrows a person's permission and know-how when it reaches something it cannot do alone, records who granted it, and turns what the person did into a bounded procedure the whole fleet may reuse.
Human Takeover for Browser Agents: Browser Use, Playwright and Computer Use Compared
How to hand a stuck browser agent to a person, on the same session, for agents built on Browser Use, plain Playwright, or a screen-driving model such as Computer Use, and how the fix becomes a skill instead of a one-off.
A Human-in-the-Loop SDK for LangGraph, CrewAI and the OpenAI Agents SDK in Python
The frameworks pause for a human differently: LangGraph interrupts a graph, CrewAI flags a task for human input, the OpenAI Agents SDK leaves it to your tools. One SDK gives all three the same three calls, and turns each intervention into a skill the fleet reuses.
How Healthcare RCM Teams Give AI Agents Permission to Act in Payer Portals
Payer portals were built for people: SSO, multi-factor codes, attestations, rules that change by plan. Here is how revenue-cycle teams let agents do eligibility, claim status and prior-auth follow-up without handing them credentials, and how each human fix becomes a reusable, bounded procedure.
Why Your Browser Agent Fails at Login, and What Actually Works
Browser agents fail at login screens for four predictable reasons. Here is each one, how to tell them apart, and the pattern that stops the same login from failing twice.
AI Agent Stuck on a CAPTCHA: The Honest Answer
CAPTCHA solvers are a losing race and increasingly a legal risk. Here is why agents hit CAPTCHAs, what to do instead, and how to make it happen less often.
How to Handle 2FA in an AI Agent Without Breaking Security
Two-factor authentication stops agents by design. Here is how to let an agent pass a 2FA step without sharing codes, storing secrets, or turning 2FA off.
Your Agent's Session Expired Mid-Task. Here Is Why It Keeps Happening
Agents that were signed in an hour ago get bounced to a login halfway through a run. The causes are mundane and fixable. Here is the checklist.
The Cookie Banner That Silently Breaks Your Agent
Consent banners cover the button your agent needs, and the agent keeps clicking underneath them. Here is why it is so common and how to make it stop for the whole fleet.
Selector Rot: Why Your Playwright Agent Broke After the Site Redesign
Selectors are a snapshot of a page on one afternoon. Here is which kinds break, which survive, and how to stop rewriting them every time a vendor ships a redesign.
Your LangChain Agent Is Stuck in a Loop. Here Is What It Is Actually Doing
An agent repeating the same tool call is not confused, it is trapped by a wall it cannot see past. Here is how to detect the loop, stop it cheaply, and route it to a human before it burns your budget.
CrewAI Task Never Completes: Diagnosing the Silent Hang
A CrewAI crew that runs for twenty minutes and returns nothing is usually one agent waiting on a wall. Here is how to find which one and what to do about it.
How to Hand an AI Agent's Task to a Human Without Losing the Session
Escalating to a person usually means the human starts from scratch in their own browser. Here is the pattern where they take over the agent's live session instead, and the agent resumes afterwards.
What Is a Compiled Skill, and Why It Beats Recording a Human
Recording a person's fix as a macro breaks the next time the page moves. Compiling it into a procedure written as intent does not. Here is the difference, with an example of each.
Why AI Agents Fail in Production (and How to Actually Fix It)
The real reason agents break in production isn't the model, it's the changing world around them. And why observability alone won't save you.
What to Do When Your AI Agent Hits a Login Wall
Login walls, 2FA, and CAPTCHAs stop agents cold. The human-in-the-loop pattern that lets an agent pause, get help, and resume.
