Is there an accompanying Agent Skill?

> Runing GLM-5.2 on local hardware Do the runes make it smarter or just run faster (or both)?

Thank you for sharing! Based on your experience, do you think a two-model system might fare better? For example, two models in serial where the second model is trained to "sniff ou…

Does anyone know why there hasn’t been more widespread adoption of OpenAI’s Harmony format? Or will it just take another model generation to see adoption?

OpenAI has already adopted Agent Skills: - https://community.openai.com/t/skills-for-codex-experimental... - https://developers.openai.com/codex/skills/ - https://github.com/openai…

And since AI agents are extremely good at using them, command-line tools are also probably 235x more effective for your data science needs.

> Vite Format: "More flexible line-wrapping" I would love more information about this feature! Bad line-wrapping is the reason I loathe Prettier.

I'm not familiar with Airflow, but MCP supports progress notifications: https://modelcontextprotocol.io/specification/2025-03-26/bas...

Long-running tasks are an open topic of discussion, and I think MCP intends to address it in the future. There are a few proposals floating around, but one issue is that you don't …

JavaScript is dead. Long live YavaScript.

Upcoming in Rails 7.1, you can specify a custom compressor for your cache, out of the box. See the `:compressor` option of `ActiveSupport::Cache::Store.new`: https://api.rubyonrail…

Very cool bot! I was looking for that kind of bot a few months ago, but I couldn't find one that was still maintained, so I created my own[1]. But if you're going to continue maint…

I created a gem which wraps all this up in a nice API: https://github.com/jonathanhefner/talent_scout So the final code from the article would look like: class ProductSearch ?", fr…

I agree with most of the points regarding user experience. But I loathe infinite scrolling, and so strongly disagree that Facebook "got it right." I think "geared pagination" with …

Disappointing... still no support for HTML5 date and time input types. Safari seems to be the last major hold out[0] keeping JavaScript-powered date pickers a (prudent) necessity. …
