Prompt and Order: Why LLM Trading Needs a Factory, Not a Fortune Teller

Orders are where trading systems stop sounding intelligent and start spending money. A model can narrate the market beautifully. It can explain momentum, liquidity, volatility regimes, inventory pressure, and the great moral tragedy of being early. None of that matters if the final system places the wrong limit order, sizes too aggressively, fills only in a fantasy simulator, or wins a backtest because it tried enough variants to accidentally find one that looked divine. ...

Search, Critique, Repeat: Critic-R Turns RAG Complaints into Retriever Training

Search failure is boring until it becomes expensive. A research agent asks for evidence. The retriever returns documents. The reasoning model reads them, continues writing, and eventually produces a confident answer. Somewhere in the middle, the evidence was slightly wrong: not irrelevant enough to trigger an obvious failure, not useful enough to support the next reasoning step. The agent proceeds anyway, because that is what agents do when we dress up uncertainty as workflow automation. ...

Scaffold and Ladder: Why AI Agents Need Meta-Reasoning, Not Longer Monologues

Workflow is where AI agents usually stop looking magical. Ask one to summarize a short memo, and it behaves like a competent intern with suspiciously fast typing. Ask it to investigate a compliance question across policies, contract clauses, ticket histories, and messy attachments, and the illusion starts to wobble. The agent searches once, reads too much at once, jumps to a plausible answer, and then politely explains the wrong conclusion with the confidence of a junior consultant who has discovered formatting. ...

Think Longer, Act Smarter: Why Coding Agents Need Behavior-Preserving Reasoning

A coding agent can fail in two very different ways. One failure is obvious: it does not think enough. It sees an error report, guesses the wrong file, edits too early, and then spends the rest of the trajectory debugging its own mistake. Anyone who has watched an autonomous coding agent wander through a repository has seen this little tragedy. The machine is busy, but not necessarily useful. ...

Don’t Average the Needle: Spectral Retrieval and the RAG Evidence Problem

Enterprise search has a very old habit wearing a very modern jacket: it averages. A policy document becomes one vector. A runbook becomes one vector. A postmortem full of operational detail becomes one vector. Then a RAG system asks that one vector whether the document is relevant. This is convenient, fast, and usually defensible — until the relevant answer is a narrow paragraph hiding inside a large document. At that point, the retrieval system is no longer searching for evidence. It is asking a crowd to speak for the witness. ...

Experience Is Not Memory: Why Learning Agents Need a Better Feedback Loop

A support ticket goes wrong. A workflow agent chooses the wrong tool. A finance assistant misses a procedural step. The usual response is familiar: add the failure to memory, rewrite a prompt, perhaps ask the agent to “reflect” before trying again. This is useful, in the same way that putting a sticky note on a broken machine is useful. It may prevent the same mistake next time. It does not prove the machine has learned how to improve. ...

Think Longer, Act Worse? What M2A Teaches About Reasoning Agents

Think Longer, Act Worse? What M2A Teaches About Reasoning Agents A coding agent does not fail only because it cannot think. Sometimes it fails because it keeps thinking after it should inspect the repository. Sometimes it writes a plausible explanation before checking the relevant file. Sometimes it burns the context window by wandering through hypotheses, each one almost reasonable, none of them decisive. The result is not stupidity in the familiar sense. It is a coordination failure: the model does not know when to reason, when to call a tool, when to absorb feedback, and when to edit. ...

Silent Errors, Loud Consequences: ASMR-Bench and the Coming Era of AI Auditors

Code review is supposed to be the sober adult in the room. A researcher writes code. A reviewer checks the code. A suspicious bug gets caught before it becomes a chart, a memo, a product decision, or—if everyone is having a particularly expensive week—a board presentation. That model works reasonably well when the failure is accidental and the reviewer has more patience than the author. It becomes less reassuring when the author is an AI research agent, the codebase is messy, the experiment is expensive to rerun, and the suspicious line looks less like a bug than a perfectly normal design choice. ...

Reviewer, Reviewed: When AI Starts Grading the Graders

Review queue. That is where many serious organizations quietly lose time, quality, and patience. A technical team writes a proposal. A risk team checks a report. A grant committee reads applications. A legal or compliance group inspects a document for missing evidence, weak logic, and embarrassing errors. Everyone agrees that review matters. Everyone also knows the reviewers are tired. ...

Evolve or Die Trying: When LLMs Stop Writing Code and Start Designing Algorithms

A developer asks an LLM to “write a better algorithm.” The LLM obliges. It writes code. The code runs, perhaps after a few rounds of apologetic debugging. The result is slightly better than the baseline, or at least sufficiently mysterious to be called “novel.” Everyone nods politely. Another benchmark table is born. ...
