Rungraph turns AI coding agent session logs into queryable, shareable graphs

0
·2 views

A developer has released Rungraph, a free, MIT-licensed open-source tool that converts session transcripts from coding agents like Claude Code, Codex CLI, and Hermes into interactive visual graphs. The tool scans existing session logs stored on disk and displays tool calls, errors, retries, and subagent actions in a timeline-based graph without requiring any additional setup or wrappers. Via an MCP integration, users can query past or live agent sessions in natural language directly from their terminal, with relevant graph nodes automatically highlighted in response. Rungraph also supports cross-team collaboration by allowing sessions to be exported as a single file that teammates can open and query in their own dashboard, regardless of which coding agent they use. The project aims to replace the common practice of manually scrolling through thousands of lines of raw session logs to understand what an AI agent actually did.

Developer Tests Hermes Agent Bot Mode With Three Specialist AI Agents

Developer Vivek Shetye published a hands-on experiment with Hermes Agent's Bot Mode, building a team of three specialist AI agents designed to hand off tasks between each other. The test focused on a research-challenge-synthesis workflow to evaluate how well AI agents can collaborate sequentially. Shetye documented what worked and what failed during the process, offering a practical assessment of the feature. He also compared Bot Mode to Hermes Agent's Kanban-style workflow to clarify where each approach is best suited. The article was published on DEV Community on August 18 as part of the Hermes Agent Challenge.

DEV Community Series Traces Reinforcement Learning From 1911 Psychology to Modern AI

A developer on DEV Community has published a multi-part educational series charting the chronological history of reinforcement learning (RL), from early psychological theories to contemporary algorithms. The series begins with foundational ideas such as Thorndike's Law of Effect (1911), Pavlov's reinforcement concept (1927), and Hebb's neural learning hypothesis (1949). It progresses through landmark computational milestones including Turing's pleasure-pain system (1948), Bellman's Dynamic Programming (1957), and Watkins's Q-Learning (1989). Later entries cover breakthroughs like Tesauro's TD-Gammon (1992) and the Policy Gradient Theorem (2000), which advanced modern RL theory. The series uses visual guides and real-world analogies to make complex RL concepts accessible to a broad audience.

Idle AWS Load Balancers Cost Up to $18/Month Each — Here Is How to Find and Remove Them

AWS Application and Network Load Balancers incur a fixed base charge of roughly $16–$18 per month regardless of whether they handle any traffic. Load balancers are often created early in a project's lifecycle but rarely deleted when the associated services are shut down, leaving orphaned resources that continue billing. Developers can identify idle load balancers by checking CloudWatch request metrics over a seven-day window and inspecting target group health via the AWS CLI. A load balancer showing near-zero requests, no healthy targets, and no DNS references pointing to it is generally safe to delete. Before removing any load balancer, teams should verify it is not serving a low-traffic but critical purpose such as a disaster-recovery endpoint or an internal admin panel.

Benchmarking AI Models Without Testing Their Servers Is a Critical Oversight

A software engineer writing for DEV Community argues that most AI model evaluations overlook server-side performance, focusing only on output quality. The article highlights a recurring pattern where teams select a free model based on strong demo results, integrate it into CI pipelines, and then face failures days later due to shared server infrastructure. Free-tier endpoints often involve shared tenancy, meaning latency and timeouts are affected by other users' workloads on the same hardware. To address this, the author developed a reproducible Python benchmarking harness that tests a model and its server together using concurrent requests and pass/fail metrics. The piece includes a disclosure that it was prepared as part of outreach for MonkeyCode, whose free model and server options were used in the benchmark.
