When agents write the code, the tooling trade-offs flip
Anchorage reversed its 2022 'no' to Bazel because agents now maintain the build tool — cheap codegen flips which CI costs are worth paying. CI stays under three minutes as the repo grows.

HEART: harness engineering via agent-native reusable tool primitives
A framework that swaps rigid API schemas for natural-language 'tool primitives' agents compose, over a 25k-function library; claims ~10% over SFT baselines and 84% task completion. Low buzz here.

Article
AIX Design Reference Encyclopedia
A free reverse-lookup reference of 229 AI-UX design questions, each mapped to research, standards and evidence ratings. Japanese-language, but a deep reference for anyone designing conversational AI.
Post
What AI actually changed in my design process
A practitioner's clear-eyed account of what shifted day-to-day — faster exploration and iteration, while direction and problem framing still land on the human. First-hand, not a hot take.
