The second axis most maps miss: not how much you hand the model, but how much of your work survives the session as state you can open and inspect. Cleanest articulation of this I have seen.

How to integrate AI agents without joining the 95% that fail

Raffaele Zarrelli — Sun, 21 Jun 2026 13:30:59 +0000

I build AI agents and automations for companies in Italy, so I read every "agents are eating the world" thread with one number in the back of my head: most agent projects do not pay off. MIT's 2025 study found that around 95% of generative AI pilots produced no measurable return to the P&L. A separate analysis of 847 agent deployments found 76% in crisis within 90 days.

The interesting part is not the failure rate. It is the cause. After shipping a few of these, my honest read is that the model is almost never the reason.

The real failure is upstream of the AI

When an agent project dies, the post mortem usually blames the wrong layer: the prompt, the framework, the tool calls, the context window. Those are real problems, and Berkeley's MAST study even catalogs 14 distinct failure modes in multi-agent systems. But they are symptoms.

The root cause is almost always that the company pointed an agent at a process that was never standardized. The work lived in people's heads, the rules had three exceptions nobody wrote down, the data sat in four places that disagreed. An agent does not fix that. It amplifies it. You automate the mess and now the mess runs at scale.

An agent does not reduce disorder. It scales whatever process you point it at, including the disorder.

There is data under this too. One analysis found projects with a clearly defined problem succeeded about 58% of the time, versus 22% for projects that started from a vague mandate like "add AI." And the reason the standard never gets written is structural: research out of Berkeley estimates roughly 80% of operational know-how is tacit, undocumented, carried by the people who do the work. That is the part an agent cannot infer.

The method: AI is the last third, not the first

The mental shift that changed my hit rate was to stop treating the agent as the project. The agent is the last third of the work. Here is the shape I now follow, roughly six months end to end for a real workflow.

Months 1-2: find the workflow and measure the baseline. Not the process that annoys you most, the one with high business impact that is still repeatable enough to standardize. Often it is the bottleneck, the step that throttles the whole flow, not the loudest complaint. Measure where it is today before you touch it, or you will never be able to prove the agent did anything.

Months 3-4: standardize. Write the procedure, make the decision criteria explicit, collapse the four conflicting data sources into one source of truth. This is the unglamorous part everyone skips, and it is where the 5% is won or lost. Standardizing does not mean writing a manual. It means making the process repeatable and measurable.

Months 5-6: build the agent and put it in test. Now the AI work begins: planning, tools, memory, evals, guardrails. By this point the agent has something solid to stand on, so the build is faster and the failures are boring instead of mysterious.

If that timeline feels slow, that is the point. The teams in the 95% compressed it to "weeks 1-2: install agent." The teams in the 5% spent most of the calendar before the model ever ran.

Where memory fits

There is a quieter reason these projects rot: the system has no memory. Every new session starts from zero, the decisions you made last month evaporate, and a human becomes the institution's memory by re-explaining the same context forever.

So before the production agent, I give the project itself a memory: the standard, the decisions, the open questions live in plain files the system reads and rewrites, not in a chat you hope retained something you cannot inspect. It is less "teach the model to remember" and more "give the project a memory you can open, correct, and trust." I open-sourced the small kit I use for this for Claude Cowork, called cowork-os, if you want to see the structure.

When the honest answer is "not yet"

The most useful thing I tell a prospect is sometimes "do not automate this yet." Low volume, an unstable process, a goal that is really about looking modern, a process that is broken upstream: in all of those, an agent is the wrong first move. Fix or drop the process first. Saying that out loud has won me more trust than any demo.

None of this is anti-AI. It is the opposite. The agent is genuinely the easy part once the process under it is real. The 5% is not a modeling secret, it is a sequencing discipline.

If you have shipped an agent that stuck, I am curious: how much of your timeline went to the process versus the model, and would you do that split differently next time?

Which process should you automate first? Not the one that screams loudest

Raffaele Zarrelli — Sun, 21 Jun 2026 12:47:16 +0000

Most teams pick the wrong first automation. They start with the process everyone complains about, because the noise feels like a signal. It is not. The loudest process is rarely the one that, once fixed, actually moves the numbers.

After doing this across a bunch of companies, I use a simple four-step funnel: surface the processes, filter them with a few signals, find the real constraint, then score the finalists. Here it is.

1. Surface the processes (the good ones are usually invisible)

The best candidates are often the ones nobody mentions, because people do them semi-consciously: the copy-paste between two tools, the manual re-formatting, the "I just check this every morning." Annoyance is loud. These are quiet. So do not brainstorm "what annoys us." Shadow a normal day instead and write down every repeated, rules-based action, especially the ones people do without thinking. You are looking for recurring, not painful.

2. Filter with the signals

A process is a strong candidate when it is:

Recurring: it happens daily or weekly, not once a quarter.
Rules-based: a human could write down how to decide, even if they never have.
High volume or high stakes: it eats real hours, or a mistake is expensive.
Structured in, structured out: data in, data out, not "use your judgment."
Sitting on a bottleneck: more on that next.

If it fails most of these, it is a bad first automation, no matter how loud it is.

3. Find the constraint

Between two equally good candidates, automate the one on your bottleneck. Output is governed by the slowest step, so automating anything else just makes work pile up faster in front of the constraint. Ask where work waits. Where do things queue? That waiting is your map. Fixing a non-constraint feels productive and changes nothing.

4. Score the finalists

For the last two or three candidates, score each on impact (hours saved or risk removed), frequency, and feasibility (how clean the rules and data are). Multiply, do not average. A high-impact process with messy, undocumented rules is a trap, not a win. The winner is usually the boring, recurring, high-frequency one that sits on the constraint and has clean inputs.

The trap to avoid

Starting with the visible, emotional process, the one in the all-hands complaint. It is visible precisely because it is irregular and messy, which is exactly what makes it a bad first automation. Start where it is quiet and repetitive. The wins that compound are unglamorous.

One thing that took me a while to learn: the hard part is rarely the automation itself, it is keeping the context. The process changes, the rules drift, and six months later nobody remembers why it was built that way. That is a separate problem, memory and documentation, and I have been open-sourcing how I handle it, but that is another post.

If you are picking your first one: ignore the noise, follow the queue, and automate the quiet repetitive thing on your bottleneck.

I gave my AI a memory, and open-sourced the whole thing

Raffaele Zarrelli — Sun, 21 Jun 2026 11:11:37 +0000

Full disclosure up front: I am a founder, and this is about something I built and open-sourced. If that is not your thing, no hard feelings.

The problem was never the model

I run a small software company. Most of my day is a pile of small, different jobs: marketing, the website, a sales follow-up, a decision about a product. I started leaning on AI chat for all of it, and the model was genuinely good. That was never the problem.

The problem was that every new chat started from zero. I would re-explain the same context, the same positioning, the same constraints, over and over. Decisions I had made last week evaporated. The AI was smart, but it had amnesia, and I was the external hard drive.

Why I did not reach for an autonomous agent

The obvious 2026 answer is "use an agent." There is a whole wave of them now, the kind that go off and do things on their own. I looked, and honestly I did not trust handing over actions I could not see or verify. I did not want something acting on my company while I was not watching. I wanted to stay in the loop. I just wanted the thing to remember.

So I went the other way: not more autonomy, more memory.

The approach: a project that remembers

I use Claude Cowork, where a "project" is basically a workspace Claude can read and write. So I gave that workspace a structure and a habit.

The structure is just folders of Markdown: a context area for who we are and what we sell, working areas for marketing and the website, and a decisions folder with a decisions log and a list of open questions.

The habit is the important part. Every meaningful task ends with a Memory Update: before calling it done, the assistant checks whether anything changed (a decision, an assumption, an open question, a risk) and writes it back to the right file. The next session reads those first.

That is it. No app, no database, no dependencies. But the effect compounds: after a few weeks the project actually knows the business, and it gets a little sharper each week instead of forgetting.

What it turned into

I cleaned it up, stripped every private detail, added a sanitized real workspace as a reference, and put it on GitHub as cowork-os, an open-source operating system for Claude Cowork. MIT.

It has three modules I actually use: a LinkedIn content system, an outcome-driven "missions" workflow, and a set of recurring automations.

The part worth calling out for builders: it started as "copy this folder, paste this installer." That works, but it is friction. So I also packaged it as an installable plugin. Now you add the marketplace and install it, and you get an always-on skill (the operating rules plus the memory protocol) and a handful of slash commands, with no copying.

If you build plugins, run claude plugin validate before you ship. It caught a YAML bug in one of my command files: a stray colon in the frontmatter that silently dropped all the metadata. Two minutes to fix, but it would have failed review.

The honest limitations

It is a convention, not magic. It only works if you keep the habit. The plugin today ships the runnable core (the rules plus the commands) but not the full templates, so the guided setup leans on the repo for the high-fidelity version. And it is tied to one tool, Claude Cowork, though the method itself is portable.

Try it, or tell me where it breaks

I am genuinely curious how other people handle memory and context across AI sessions, and where this approach falls apart at scale. If you try it, tell me what felt clunky. I am iterating in public.
