🔬 New AI Craft
1. Building Agents That Don't Break Themselves — Agent Reliability Engineering
fly.io's deep dive into engineering patterns for building AI agents that don't self-destruct. Covers state management, error isolation, retry strategies, and observability — the engineering layer that turns agents from "working" to "reliable" in production. Unlike task-planning frameworks, this focuses on runtime robustness: preventing context bloat in long tasks, handling side effects from autonomous tool calls.

2. Does Code Cleanliness Affect Coding Agents?
New ArXiv paper introduces an evaluation protocol based on minimal-pair repositories — matching architecture, dependencies and external behavior, differing only in static-analysis rule violations and stylistic quality. Results show code cleanliness significantly impacts agent navigation and modification efficiency. A direct signal for anyone using AI coding agents daily: clean code isn't just for humans anymore.

3. AI Tutor Achieves 0.71–1.30 SD Effect Size in Dartmouth Course
Empirical study from ITB 2026: an AI tutoring system deployed in a real Dartmouth course produced 0.71 to 1.30 standard deviations of learning improvement — far exceeding the 0.3–0.5 SD typical of traditional interventions. One of the few high-quality controlled experiments proving AI tutoring can already outperform human-led instruction in standardized learning scenarios.

🛠️ Tools & Tips
1. Context Graphs — How AI Agents Store and Reuse Past Decisions
Nanonets explains context graphs: agents capture decision traces, build structured memory, and reference historical reasoning paths in subsequent tasks. For developers who want their agents to have long-term memory beyond a single conversation.

2. Peek-CLI — Let Claude Code See the Browser
Open-source CLI tool that extends Claude Code's perception to the browser — read web pages, take screenshots, and interact based on visual context. Bridges the gap between terminal-based agents and web content.
