Retrying isn't debugging. My coding agent once re-ran the same failing test 9 times, tweaking a line each pass. Now it gets 2 attempts per failure. Attempt 3 must open with a written hypothesis. Fewer loops, more real diagnoses. #claudecode #ai #aiengineering #buildinpublic

Flipped the review direction: my coding agent now reviews my commits before I merge. Five human PRs in. It caught a missing index and a null path I would have shipped. Zero false alarms. It reads my code more carefully than I read its. #claudecode #ai #aiengineering #buildinpublic

AWS just released a guide on migrating multi-model AI agents to Amazon Bedrock AgentCore runtime. This shift reduces operational overhead by offloading container orchestration, scaling, and observability to managed services. Developers can now focus on agent logic, not infrastructure. #AIEngineering

Gave every task my coding agent runs a hard dollar cap: $1.50. Hit the cap and it stops, writes down what's done and what's missing, and exits. No heroics. A month in, the tasks that blew the cap were rarely hard. They were underspecified by me. #claudecode #ai #aiengineering #buildinpublic

My coding agent shipped a page that ran 412 DB queries per load. Every test passed. The tests seeded 3 rows. Production had 400. Now my seed script makes 1,000 of everything, and the agent pastes the query count in its summary. #claudecode #ai #aiengineering #buildinpublic

My coding agent has never seen a single API key. Secrets sit in one file it's told not to read. A tiny lookup command returns a value only at runtime, and every call is logged. Two months in: zero keys in commits or transcripts. ~20 lines of shell. #claudecode #ai #aiengineering #security

Scaling agentic AI on AWS isn't just about infrastructure—it's about handling non-deterministic compute, IAM scoping, and token costs. Here's what we learned from real-world production setups. #AIEngineering #AWS #AgentDevelopment

I don't manage people. I manage systems. Systems compound. One dropped relay collapses the whole race. Design transitions first. #AIEngineering #BuildInPublic
