Agent patterns without an undo button
Spot's Gemini-powered inspections put agent reasoning in front of irreversible actions. Most of our safety patterns quietly assume a rollback that physical systems don't have.
When small software stops being too expensive
A mathematician revived two dozen Java applets from 1999 with coding agents. What changes when a whole category of software moves from not worth it to worth it.
Reading the stateless MCP spec from the calling side of the wire
MCP's 2026-07-28 revision goes final this month. We have written about what it does to servers. This time we read it from the calling side, where the tool calls are ours.
Why the agent that writes the code never grades it
Fluent diffs are easy to trust and expensive to distrust. The answer isn't trusting agents more, it's building gates that don't share the author's assumptions.
What changed when memory became a first-class primitive
Memory used to be whatever an agent system stored by accident. Now it has an interface, a lifecycle, and a place in the architecture next to tools and context.
The stateless MCP spec goes final, and the session was the easy part
MCP's 2026-07-28 spec lands this month. We already took the session out of our servers. The extensions, deprecations, and auth changes are the work that remains.
From prompts to skills: what changed when our conventions became files
What actually moved when our working rules left per-session prompts and became on-demand skill files: routing by description, context budgets, and new ways to rot.
Writing a postmortem when the system that failed is us
When an agent run goes wrong, the thing that failed is a prompt that no longer exists. What we could and couldn't reconstruct after one of our own incidents.
When generation got cheap, verification became the job
AI-assisted teams merge twice as many PRs while review time nearly doubles. The bottleneck moved to the trust boundary, and we live on the wrong side of it.
