Claude Code Hooks Tutorial: 5 Production Hooks From Scratch
Build 5 production Claude Code hooks from scratch with full JSON configs: auto-formatting, security gates, test runners, notifications, and quality checks.
AI DevelopmentAgent Sandbox Security Is a Suggestion: Three Failure Levels
An attacker opened a GitHub issue and shipped malware in Cline's next release. Agent sandboxes fail at three levels. Here is what actually works.
AI & TechnologyAgent Sessions Are the Real Commit Messages We Discard
Git captures what changed. Agent sessions capture why. When agents write code, the session transcript is the real design document — and we discard it.
AI & TechnologyAI Agent Observability: Monitoring What You Can't See
AI agents consume disk, CPU, and network with zero operator visibility. Three observability layers close the gap before damage is irreversible.
AI & TechnologySilent Egress: The Attack Surface You Didn't Build
A malicious web page injected instructions into URL metadata. The agent fetched it, read the poison, and exfiltrated the API key. No error. No log.
AI & TechnologyBuilding a Hybrid Retriever for 16,894 Obsidian Files
49,746 chunks, 83 MB, zero API calls. How BM25 + vector search + RRF fusion in one SQLite file turns 16,894 Obsidian files into a queryable knowledge base.
AI EngineeringAGENTS.md Patterns: What Actually Changes Agent Behavior
Which AGENTS.md patterns actually change agent behavior? Anti-patterns to avoid, patterns that work, and a cross-tool compatibility matrix for 8 tools.
AI DevelopmentClaude Code Skills: Build Custom Auto-Activating Extensions
Build custom Claude Code skills that auto-activate based on context. Step-by-step tutorial covering SKILL.md structure, frontmatter, LLM-based matching, and team sharing via git.
AI DevelopmentThe Performance Blind Spot: AI Agents Write Slow Code
118 functions with slowdowns from 3x to 446x in two Claude Code PRs. AI agents optimize for correctness, not performance — here's the data.
AI EngineeringWhat Actually Breaks When You Run AI Agents Unsupervised
Seven named failure modes from 500+ autonomous agent sessions. Each has a detection signal, a real example, and a concrete fix. The taxonomy HN asked for.
AI EngineeringThe CLI Thesis: Why Agent Architecture Beats IDE Plugins
Three top HN Claude Code threads converge on one conclusion: CLI-first architecture is cheaper, faster, and more composable than IDE agent workflows.
