AgentLens Moves Coding-Agent Safety From Prompt Policing Toward Runtime Monitoring

AgentLens Moves Coding-Agent Safety From Prompt Policing Toward Runtime Monitoring

The uncomfortable truth about coding-agent safety is that the dangerous part often does not happen at the prompt. It happens mid-flight. The agent reads a repository, absorbs a poisoned instruction from a README, follows a tool result into the wrong context, starts forming a shell command, and only then becomes

RigorBench Says Coding-Agent Leaderboards Are Measuring the Answer, Not the Engineering

RigorBench Says Coding-Agent Leaderboards Are Measuring the Answer, Not the Engineering

Most coding-agent benchmarks still grade agents like contest submissions: did the patch pass, did the issue close, did the scoreboard increment? That is useful, but it is also a dangerously compressed view of software engineering. RigorBench, a new arXiv paper on “engineering process discipline” in autonomous AI coding agents, argues

llama.cpp Is Quietly Becoming the Local Agent Runtime, One API Compatibility Fix at a Time

llama.cpp Is Quietly Becoming the Local Agent Runtime, One API Compatibility Fix at a Time

The most important local-AI releases increasingly look like schema chores. That sounds dismissive until an agent stack breaks because a JSON field is missing. llama.cpp release b9763 adds an item-level id field to llama-server Responses API function-call outputs. Six additions, three deletions, one changed file in the relevant PR.

Qwen Code’s Nightly Fixes Are the Boring Control-Plane Work Coding Agents Actually Need

Qwen Code’s Nightly Fixes Are the Boring Control-Plane Work Coding Agents Actually Need

Qwen Code’s June 22 nightly is not the kind of release that gets keynote applause. Good. Coding agents do not become production tools because the launch post says “agentic” more times than the previous launch post. They become production tools when boring runtime semantics stop lying to automation. This

OCR Is a Reminder That Small Specialist Models Still Beat Giant VLMs at Actual Jobs

OCR Is a Reminder That Small Specialist Models Still Beat Giant VLMs at Actual Jobs

Every few months, the industry needs a small model to walk into the room and embarrass the generalists. PP-OCRv6 is that reminder: a 1.5M-to-34.5M-parameter OCR family claiming better document text detection and recognition than frontier-scale vision-language models on PaddleOCR’s own multi-scenario tests. That does not mean a

Multimodal Models Are Judging the Outfit More Than You Think

Multimodal Models Are Judging the Outfit More Than You Think

A vision-language model that changes its social judgment when the same person puts on different clothes is not merely “seeing context.” It is making a policy decision from style. That is the reason StylisticBias: A Few Human Visual Cues Drive Most Social Biases in MLLMs is worth attention. The paper

LLM Judges Can Infect Each Other With Bias — Measure the Network Before You Trust the Score

LLM Judges Can Infect Each Other With Bias — Measure the Network Before You Trust the Score

LLM judges were supposed to make evaluation cheaper. Then they became part of the system being evaluated. That is the uncomfortable premise behind Contagion Networks: Evaluator Bias Propagation in Multi-Agent LLM Systems. The paper studies what happens when model agents evaluate each other and update behavior from those evaluations. The

Agent Guardrails Need Probabilities, Not Just Boolean Vibes

Agent Guardrails Need Probabilities, Not Just Boolean Vibes

The most dangerous fiction in agent security is that a guardrail is a yes/no box. That fiction is convenient. It lets product teams draw neat diagrams: prompt comes in, classifier checks it, agent calls a tool, policy passes or blocks. It also collapses the actual risk model of a

Security Fine-Tuning Can Calibrate the Output While Leaving the Model Clueless

Security Fine-Tuning Can Calibrate the Output While Leaving the Model Clueless

The lazy version of “AI for security” is to fine-tune a code model, report a binary accuracy number, and hope nobody asks whether the model is finding vulnerabilities or merely learning when to say the scary word. Calibration Without Comprehension asks the uncomfortable question directly, and the answer is not

SoftSkill Compresses Agent Skills Into 32 Virtual Tokens — and Shows Where That Trick Breaks

SoftSkill Compresses Agent Skills Into 32 Virtual Tokens — and Shows Where That Trick Breaks

Markdown skills are one of the more sensible things agent platforms have converged on. They are readable, reviewable, portable, and cheap to author. They are also long, repeatedly injected, and interpreted from scratch by a model that may or may not translate prose into the behavior you intended. The obvious

AGENTS.md Works When It Is Debugged Like Code, Not When It Is Treated Like Lore

AGENTS.md Works When It Is Debugged Like Code, Not When It Is Treated Like Lore

AGENTS.md has become the new README-for-robots: part documentation, part incantation, part apology to the coding agent that is about to discover your monorepo’s build system. The useful question is no longer whether repository guidance helps. Sometimes it does. The question is whether teams are debugging that guidance like

4-bit KV Cache Is the Agent Cost Story Hiding Under the Model Benchmark

4-bit KV Cache Is the Agent Cost Story Hiding Under the Model Benchmark

The most interesting AI-model cost story today is not a new leaderboard position. It is the thing that happens after your agent has read half a repository, opened a dozen tools, accumulated a giant prefix, and now needs to answer one tiny follow-up without turning the GPU into a space
