Agent 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 & TechnologyWriting
Thoughts on design, development, AI infrastructure, and building products.
Silent 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 & 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 & 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 EngineeringThe 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.

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 DevelopmentAnthropic Measured What Works. My Hooks Enforce It.
Anthropic analyzed 9,830 conversations. Iterative refinement doubles fluency markers. Polished outputs suppress evaluation. Quality hooks force iteration.
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 Protege Pattern: Small Models That Know When to Ask
A 7B model with sparse expert access matches agents 50x its size. Route routine work to small models and judgment calls to frontier models.
AI & TechnologyContext Is the New Memory
Context engineering is the highest-impact skill in agent development. Three compression layers turn a 200K token window from liability into advantage.
