Best of your X follows: cache-friendly uvx, Canadian research, and agent UX

Developer tooling

Simon Willison on cache-friendly uvx in GitHub Actions

• Simon says he found a way to run uvx in GitHub Actions without downloading a fresh package on every run. 1
• The recipe uses UV_EXCLUDE_NEWER as part of the cache key and flips UV_OFFLINE=1 on cache hits, so missing tools fail fast. 2
• The practical effect is a repeatable CI setup for one-off Python tools without maintaining an extra helper file. 2

Ethan Mollick on Codex remote control and stale docs

• Mollick says the iOS ChatGPT app's Codex remote feature is good, but the setup instructions do not match the desktop menus. 3
• He says the same documentation mismatch shows up across the Labs surfaces, which makes the workflow rough at first use. 3
• The complaint is simple: the feature exists, but the docs are bad or out of date in several places. 3

Agent products

François Chollet on Airtap's SMS-first automation layer

• Chollet says Airtap turns SMS into a headless agentic layer for mobile apps, running errands in the background and only pausing for authentication. 4
• Airtap's site describes a cloud phone, live screen streaming, and routine building from the web or by text. 5
• Its template library already covers flight tracking, LinkedIn applications, coupon sweeping, apartment hunting, and grocery ordering. 5

Research and capital

Anthropic on Canadian AI research

• Anthropic says it is committing $10 million CAD to Canadian research institutions and working with Amii, Mila, Vector, CHEO, CAMH, Université Laval, the University of Toronto, and the University of Saskatchewan. 67
• The company also published a Canada brief from its Economic Index alongside the announcement. 7
• That brief says Canada ranks eighth globally in Claude use, and translation requests cluster in provinces where government work is concentrated. 7
