I couldn't find an explicit reference for the naming, but for anyone wondering there is a Hamilton example: https://github.com/apache/burr/tree/main/examples/multi-agen...

abirch• 1 month ago

Burr is named after Aaron Burr, founding father, third VP of the United States, and murderer/arch-nemesis of Alexander Hamilton. What's the connection with Hamilton? This is DAGWorks' second open-source library release after the Hamilton library We imagine a world in which Burr and Hamilton lived in harmony and saw through their differences to better the union. We originally built Burr as a harness to handle state between executions of Hamilton DAGs (because DAGs don't have cycles), but realized that it has a wide array of applications and decided to release it more broadly.

elijahbenizzy9• 1 month ago

Right it was a bit of a joke. Originally stefan and I presented frameworks when we were at stitch fix -- stefan called his "hamilton" and I called mine "burr". His was better for the use-case. But then we wanted to build something for state machines as opposed to DAGs, so we called it Burr. I wanted the git tagline to be "make your agents go burr..."

I just create a MVP chatbot for a client that has a Django app. I took the route to no frameworks. Claude/codex wrote the agent loop, the tools, the streaming..it’s working well for the MVP, we’ll see

First time I hear about Burr, curious why it was incubated in Apache.

elric• 1 month ago

Why wouldn't it? The ASF has a long history of incubating new FOSS projects. Some graduate and become household names. Others fail and end up in the attic. The ASF can provide organisational support and generally fosters good communities.

Oras2• 1 month ago

My point was this is a crowded market now, why would they pick a platform that is not known? I did search HN and this platform was only shown once 2 years ago, and from their releases, they are still 0.42 after two years.

It might sounded that I’m against the move, but I’m just curious as what apache found in the platform to get incubated

krawczstef5• 1 month ago

Cause I submitted it. Learning the Apache process and cranking on other things has been a slow process. But we've got some momentum and beginning more regular releases.

hmokiguess• 1 month ago

How does this compare to https://strandsagents.com/ ? I'm interested in tools in this space, right now I'm not attached to one, but Bedrock + Serverless on Agent Core feels like the "easy guided path" though I don't like the platform lock-in

thedougd• 1 month ago

Curious about other experiences.

I’ve been playing with this stack and left wondering if Strands provides any secret sauce with Agent Core. So far it doesn’t feel that way and sometimes they even feel at odds with each other.

fnordpiglet• 1 month ago

I think strands and agentcore don’t have a ton of overlap but I have found agentcore makes running strands frameworks pretty easy and relatively inexpensive. I like strands in that it’s the most mature (IMO) that isn’t specific to a model provider - although I found using things like vertex to require a lot of custom work to get caching and other things to work properly, the maturity is all on bedrock.

I’ll need to dig into burr - I’m not finding strands has an insurmountable maturity to it but it’s not carrying a lot of weird opinion (like some of the other OSS frameworks seem to be highly infected with) and is pretty practical in what it exposed and does, and is most like the agentic frameworks I’ve worked with inside FAANG. If burr can meet that and keep growing I’d probably look at moving to it as I also get a sense strands has a bit of the Amazon “highly probable to be abandoned once the managers and PMs get promoted” feeling.

elijahbenizzy9• 1 month ago

Strands is more opinionated and higher-level, also not vendor neutral.

brotchie3• 1 month ago

I'm still on the fence about agent frameworks, they have their place, and it depends on the nature of the agent: e.g. "Low latency, return a good enough response in 3 seconds, vs. working for 3 hours on a problem."

BUT, if you boil it down, an agent really is context building, making an LLM call, executing requested tool calls, parsing the final model output, returning it to some frontend. There's extensions like memory, async tool calls, etc, but not THAT complicated from a traditional software engineering perspective.

Everyone seems to want to build their agent framework. But if you're tasked with building an agent, I've found it much easier and more maintainable to just build 1:1 code for THAT agent: most of the abstractions you get from an agent framework purely get in the way and obfuscate core agent logic.

You end up being forced to use the abstractions chosen by the agent framework, which sometimes are a mismatch for what you're actually trying to do.

hilariously2• 1 month ago

Couldn't agree more - tried to convince a business that doubling down on OpenClaw wasn't going to solve problems except for some 0-1 stuff, and that almost immediately they'd run into roadblocks because most of the product wouldn't serve their use case.

4 months of mostly spinning their wheels later they launched a really lackluster OC product that's effectively DOA.

tcdent3• 1 month ago

OpenClaw is an application, not a harness. Yes, it contains a harness, but it is a complete product.

When building an agentic workflow there are enough primitives that rewriting them from scratch every time makes zero sense.

What is a tool? How does the LLM understand the tool? Formatting a native function into a serializable input/output pattern makes sense to generalize and that does not need to exist repeated in everyones application code.

We use libraries to interact with the APIs themselves; nobody would say writing a spec-compliant API client was poor practice. Agentic harnesses are just one layer above: I need to call the API and I need to do it with certain expected conventions.

trollbridge• 1 month ago

It’s painfully obvious that you can just open your coding harness and… tell it you’d like to make an agent. They’re simple to write.

elijahbenizzy9• 1 month ago

This is where it's nice to have some guardrails -- coding agents work etremely well with limitations.

peterbell_nyc4• 1 month ago

The agent isn't the hard part - it's the orchestration, skills, research systems, adversarial reviews, dreaming/compounding, context management and all the rest. Plus all the annoying hygiene tools to "poke the agent that got a clear prompt and decided to just sit there and wait for no good reason" and "delete the remote branches that the prompt told all the agents to delete but some of them forgot to":)

vanuatu2• 1 month ago

my job rn is just building agents

the hard part about building agents isnt the framework it's discovery, context, traditional engineering, handling the last mile

there are some invariants like the loop, tools, observability, guardrails, monitors etc...

brotchie3• 1 month ago

100% agreed, the "this is what an agent looks like to write" is the wrong pitch for a new agent framework.

The better pitch would be, "this is how easy observability, guardrails, monitoring, deployment, evals, versioning, A/B testing are with our framework." What the agent code looks like is somewhat incidental.

kristjansson• 1 month ago

Obscuring core logic is the most egregious part of most agent frameworks. One needs a clear view of what, exactly, is being sent to the underlying language model, and what's coming back. Everything in an 'agentic' application is realized as a sequence of tokens or a call to a provider eventually. It should be clear and obvious from ~all layers of the app what that's going to look like.

throw1234567891• 1 month ago

Have a look at pi.

cpard• 1 month ago

Most framework vendors don’t have an incentive to make things less obscure. The agent framework is free/open source and they make money primarily from selling observability products for agents. Even if they don’t intentionally obscure things, they just don’t have the motivation to optimize that part.

pjmlp• 1 month ago

Unfortunately agent orchestration frameworks feels like the second coming of BEPL, and the incentives are all wrong.

pianopatrick• 1 month ago

I like to think of it as "AI prompting algorithms". Like instead of just this prompt gets this result it's A prompt then B prompt the C prompt gets a result.

And just like when people were trying to figure out which sorting algorithm made the most sense, we are all just trying to figure out which prompt algorithms with which models lead to good results.

chuckadams2• 1 month ago

The most interesting evolution of my agent workflow over the past year is that I've dropped all the language gimmicks: I used to use particular emoji to mark parts of code as hints to the AI, I structured planning docs in very rigid language for different types of instructions, and generally optimizing my language for machine consumption. That's all gone now: all my comments, directives, plans and so on are just plain and clear English, nothing more. They're direct and unceremonious, but no longer bullet points that were nearly caveman-speak. It just works better that way.

cyanydeez• 1 month ago

Agents are a way to de-bloat the context. The way LLMs function, you absolutely need to find the sweet spot for a given task, and if the primary LLM has to go through a bunch of failures to find a working function, those failures are better contained in an agent and disposed of.

Obviously, you could have a different LLM like a "angel" that prunes a primary agent of the context it doesn't need, but I think the realistic KV cache problem is will determine the optimal structure: you want the work do be done in the most efficience KV cache (context-reuse) as much as possible.

There's definitely more to it than just spawning agents.

bko• 1 month ago

Take a simple workflow. You have a query it goes to a classifier. The classifier determines what workflow it should route the request to.

Then you have a general workflow that has a set of skills (prompts) and tools. And that could be recursive.

So if you do something like "rename this file" you have to build up a workflow like:

[classifier]

what's the workflow -> rename

[rename workflow]

list files (tool call)

figure out relevant predicate (LLM)

convert predicate into a filter query give the context of the files (LLM)

figure out what you want the new name to be (LLM)

create the request body and hit the tool

approval workflow

formatting

It's a lot to manage and orchestrate and that's just one simple example. You'd like want to use the same building blocks to delete a file or move it. Even to know the right concepts is difficult as we're a bit deluded on whats going on in the background of these modern AI apps like Claude and GPT that do a lot of this stuff for you

elijahbenizzy9• 1 month ago

Right I think this is why we made it unopinioated to a fault. Burr doesn't really do these things rather it just provides an orchestration framework. So it's pure BYO functions, classes, components, etc...

mbreese• 1 month ago

I'm somewhat in agreement. I like building 1:1 code for that specific agent.

Where I'm starting to question this is maintainability. When I come up with a new technique or way of doing something in my new agent, how can I update an older agent. Do I want to update the older agent?

But, I get what you're talking about w.r.t. building for the exact problem at hand. For example, I'm guessing that Apache Burr has support for a plugin-able vector RAG system (or at least it will if it doesn't now). That's great, but I want my RAG system to add documents to the context and keep them as part of an updated system prompt with some very specific tweaks that happen as part of that process. This is a bespoke way of working with an existing concept (RAG) that doesn't lend itself to using any specific framework.

In my use-case, bespoke is the way to go. But then I'm still stuck with having to make engineering choices for updating older agents. So, I see your point.

krawczstef5• 1 month ago

yep - here's something cool an end user wrote with Burr - https://github.com/msradam/phoebe

Burr just helps you, the engineer, to really control the primitives. Then adds some cool features you don't have to think about -- like observability :)

peterbell_nyc4• 1 month ago

For me the heart of an agentic system is NOT using agents (except when you really have to). Components of a working system include: - Pipelines/recipes to describe multi-step flows (deterministic, agentic and HiTL steps), loops, conditionals, exit-on's for max loop iteractions, etc - The logistics to actually run the model and HiTL steps reliably across multiple agent worker pools - Management and delivery (and security/governance and permissioning) of thick skills with code to do as much as possible - Context management so the right agents have the right context for the right sessions at the right time - Project management - ability to store and access tickets, dependencies, track progress, restart stuck ticket claims, etc - Transcript saving, memory features and dreaming/compounding capabilities so the agents continue to learn from each session - o11y for understanding whats happening, tracking costs and usages, etc - Evals and auto-tuning of prompts so you can go cross model provider and also lock to a model version so you can do an ROI on each model version upgrade - Sandboxes for running the actual model sessions

Don't need to get it all from one vendor, but that feels to me like the toolkit and for most use cases I'd argue: - Don't limit yourself to a single model provider (anthropic, openai, etc) - Own your context - Own your compounding

sdesol4• 1 month ago

Can you comment more on

Context management so the right agents have the right context for the right sessions at the right time

I'm going to do a show HN tomorrow that explains how you can give your agents years of experience. The basic idea is, you would commit in your repo or download manifests (JSON files) that can be converted to "Brains" (SQLite databases). Each brain can have its own properties.

For example, I provide a "code intent" analyzer (instructions for AI) that says when analyzing a file, extract this metadata. For the code intent analyzer, I have the AI extract a single sentence purpose for the file. So if you execute:

gsc rg cache --db code-intent --fields purpose

you get all matches for 'cache' plus the matching file's purpose like "Modify file to update caching strategy". This is how the agent can tell if the file is talking about cache vs. whether this file is what you should change if you want to update the caching strategy.

So for what you described, you can have a brain for different stages of a task. It can be as simple as, in the planning stage, make sure you do this if you need to touch this file.

I am working on a rust-blast-radius brain that uses `syn` + AI generated metadata to help you understand "what if I changed this file, what would be affected". With the rust-blast-radius brain, the AI can summarize the types of files that will be affected without having to open the file based on what has been changed or discussed.

So you can have a rule like, if I make changes to a Rust file, make sure to do a blast radius analysis so we don't forget to consider something.

Does this align with what you are looking for?

agentifysh• 1 month ago

100% this

you dont need a framework

fxwin• 1 month ago

The advantage of frameworks isn't that they make it easier to write the actual agent, it's tooling + observability + ... Even Langchain, for all the (deserved) criticism it gets made this very clear very early: It might be easy/easier to write your own chatbot from the ground up, but what happens if you have to add observability/tracing? Being able to just add one environment variable and instantly have a UI where i can nicely go through all of my traces with basically 0 additional effort is something a hand rolled solution just can't really compete with

freakynit2• 1 month ago

This only becomes relevant if your execution graph is complex/big enough. Otherwise, all it takes is less than 30 minutes to add telemetry to all needed points. Doing manually also gives you better control on what you really want to track (to save costs).

freakynit2• 1 month ago

Yep.. same. I build my own agents... all use-case specific. Keeps the code super minimal, and avoid unnecessary complexity. I have tried a few of these, but nop.. no help.. only more work (and issues).

toddmorey• 1 month ago

Anthropic seems to agree with you as more recent Claude updates have it just building task specific harnesses as needed.

dd8601fn• 1 month ago

I’ve said something similar about dozens of frontend frameworks. It’s massive abstraction and convolution for some future payoff that’s obviously never going to happen.

But sometimes people just need something to do, or something fun to play with, and “the next guy” rarely matters that much… so who cares that you’ve saddled them with the result of your paid playtime?

andai4• 1 month ago

So before AI I had the experience, more often than not, that it would take me longer to figure out how to use someone else's thing (or get it to do some particular thing, which often turned out to be impossible), than to just make my own.

And that was before I could just ask the computer to make it for me!

But most people seem to be the other way around. They'd rather deal with abstractions and boilerplate instead of writing the actual code.

lukebuehler• 1 month ago

Arguably, if your agent needs a lot of custom logic to drive the agent loop it isn't an "agent" at all. At best it is an agentic workflow, or rather a workflow with some LLMs calls in between.

I think that's why agent SDKs feel like the wrong abstraction. If you are writing a workflow, use a workflow engine (Airflow, Temporal, etc), and call some LLMs with a small LLM library. If you need a "real" agent, use a full-featured agent harness, like Codex or CC or Pi or whatever, then load it up with all the tools, skills, mcps that it needs, and let it rip.

Incidentally I've been building a full featured agent harness that runs inside durable workflow engines [0], but it is designed _not_ as an SDK but rather as a standalone, full-featured harness with an API.

A builder pattern and decorators.

Yes, Python has decorators, but they're best used as "filters" that apply to functions or methods. Cache this, serialize the output of this function always, prepare this function to be used as a tool by an agentic harness. Not registration, not flow control. You may disagree but someone has to say it; FastAPI influenced the modern use of decorators far too much in the wrong direction.

Builder patterns are a Rust convention, because Rust has no named keyword arguments. A Python function already exposes a named contract. There is very little reason to ever to sequentially pass configuration parameters in chained method calls. If you need to add state that doesn't exist yet to a constructor or factory, that is not a builder pattern. That is registration. The one place where builder patterns should be tolerated is query builders. They iteratively build on a concept and having the additional "slot" for metadata (method name plus keyword arguments) is genuinely useful. Using methods which accept single parameter instead of keyword arguments is incorrect.

mkarrmann• 1 month ago

Builder pattern isn't only used in Rust, but I agree it's hideous to use in Python.

tcdent3• 1 month ago

Fair point. I should have said "popularized in the modern software vernacular by Rust".

giancarlostoro2• 1 month ago

Doesn't look any different than doing the same in C# or Java to me, it is kind of pointless in Python, the one thing the pattern gives you is building a class in such a way that you the developer know exactly what's what, so its really a developer ergonomics thing is how it looks like to me.

elijahbenizzy9• 1 month ago

So decorators here specifically attach metadata to make a function a reusable component. Builder makes a workflow. In Hamilton it's all decorators because it's purely declarative construction (sans reusability, really).

anentropic• 1 month ago

What is the argument against implementing registration pattern with decorators?

CuriouslyC• 1 month ago

The best agent framework is Pi (pi.dev). It is minimal and doesn't assume a use case, runs fine interactively or non-interactively, has an active community building with it and supports everything you need to build whatever kind of agent you want with plugins.

I was looking at their docs and Burr has agent cookbooks to get started with this, and it can handle multi-machine workflows. Is this not what you were looking for? I am not sure how it integrates and uses skills etc, but it seems like it should work to me.

Not to kick dirt on their faces, but I also think Discord is just not the proper chat community open source projects should have.

Might be my IRC mind talking, but a proprietary service like Discord, or Slack, or even Telegram at times, is just not suitable for the target community, as there's often a data privacy concern.

I never had a Discord account, and I'm hoping I can keep that streak.

msradam• 1 month ago

I have enjoyed using this framework in my personal and work projects, having a reliable stateful workflow for AI models while getting free observability. I stitched a tool that allows mounting a Burr state machine as an MCP, giving agents a rail to follow, and no matter how complex the state machine gets the MCP tools are constrained to state machine navigation: https://github.com/msradam/theodosia

I am currently working on skills-to-state-machine conversions, since a lot of popular skills out there are already written as phases for an AI model to follow, so it would be great to leverage the explicit functionality of Burr to make that more reliable. Thank you for this amazing project.

I don't know. This is a very naive version of what reliable AI agents are all about.

Reliable means "can it finish the job that was tasked to do". It certainly has nothing to do with state machines.

Yes, I have nothing against Tailwind as a technology. My gripe is that you can now prompt an LLM “make a stylish homepage for my product” and they almost exclusively spit out this Tailwind template.

If that’s all the effort you are going through to make your brochure site, I can only assume the same care was given to the actual product.

sermakarevich• 1 month ago

My strong opinion is that every SE should go for agentic engineering these days: understand the limitations, how to shift them, and how to squeeze the maximum possible out of AI. The AI boom is seeing hundreds of billions, close to a trillion, in investments — with yesterday's announcement from China about investing $300B in a nationwide grid of data centers. Models are becoming smarter, and the gap where yesterday's models were unable to do something is closing fast. I look at agentic engineering from the complexity perspective. Give an agent a simple task like inserting an assertion and you can be 100% sure it will do it correctly. Give it a complex task made of many subtasks in a complex codebase and it will fail. There is a boundary of complexity that a single call to an agent can handle. We can push this boundary if we decompose the task into many small ones and provide a sufficient description of what has to be done.

I found the Spec Driven Development approach works nicely for me, and I've been using it since Feb 2026 for all my mid+ size projects. I started with the GSD plugin, but it soon became too heavy, so I implemented my own lightweight SDD-based workflow for Claude. A friend of mine ported it to gemini-cli, and that version was added to Google's approved third-party frameworks for internal usage. The idea is to decompose feature implementation into multiple steps, task implementation into multiple subtasks, and be able to clear the context after every task/implementation.

Repo: https://github.com/sermakarevich/sddw

Slides: https://docs.google.com/presentation/d/1SjKXF7hkoqyiN9-3tBGY...

When SDD was not enough, I started playing with scaling a single AI worker to multiple, and then got to an agent swarm. Built on top of a centralized Beads database, claude -p headless execution, a UI, a custom ask_user MCP, and Telegram integrations, fleet (the app name) lets me add many tasks in advance, control the number of workers executing them, and use any kind of coder/model. It works nicely with the SDDW implementation phase. It shines when you keep creating tasks, define dependencies between them, and give clear descriptions. For personal projects I can queue up 70 tasks for an overnight run, set the number of workers to 1 to not be blocked by usage limits, and let it roll.

Repo: https://github.com/sermakarevich/fleet

Slides: https://docs.google.com/presentation/d/1O_pXyKdtpRG2ORD1xw7s...

Since Fable 5 appeared, I've been changing the way I work with fleet. Instead of adding tasks/descriptions/dependencies to fleet myself, I talk to Fable: specify the goal, ensure understanding, and let Fable 5 add tasks to fleet. Fable is expensive, but in this setup it doesn't code — it just investigates, designs, decomposes, and creates tasks. Workers use the cheaper Sonnet 4.6 model.

Reliability comes with task implementation decomposition into multiple steps, feature decomposition into many smaller and simpler subtasks, having better description, clean and focused context.
