It's not for getting a full charge, you do that at home or at one of the DC fast chargers in the article. You use this to recoup a few miles when at the grocery store or getting lunch. And it goes even further if you're on a motorcycle or ebike!

Just submitted ForecastSkill to the 2025 OpenWeather Challenge, a Claude Skill that scores weather conditions for activities like skiing, hiking, and picnics as well as gets up-to-date weather forecasts from OpenWeather's API right in your Claude chats. Code: github.com/kevinl95/ForecastSkill

A Claude chat window with the text: "Use the forecast-skill to tell me when the best time to go skiing at Loveland is

I'll read the forecast skill first to understand how to use it properly.

Now I'll use the activity recommendation feature to check skiing conditions at Loveland:

bash
python /mnt/skills/user/forecast-skill/skills/get_weather.py activity skiing "Loveland, Colorado"

Based on the 5-day forecast, Thursday, November 20th is the best day for skiing at Loveland with the highest score of 79.5/100.

Here's the breakdown:

Thursday, Nov 20 - Best day (score: 80) - Coldest at 8.8°C with overcast clouds
Tuesday, Nov 18 - Second best (score: 77) - 13.8°C with broken clouds
Monday, Nov 17 - Good (score: 75) - 14.3°C with broken clouds
Wednesday, Nov 19 - Good (score: 74) - 14.8°C with overcast clouds
Sunday, Nov 16 - Warmest/least ideal (score: 65) - 19.7°C with scattered clouds

The cooler temperatures later in the week, especially Thursday, will provide better snow conditions. The overall period rates as "Good" for skiing with an average score of 74/100."

A Claude chat window with the text: "Use the forecast-skill to tell me what are the best days for hiking in Colorado

I'll first read the forecast skill to understand how to use it properly.

Now I'll use the activity recommendation feature to find the best hiking days in Colorado. Since you're in Erie, Colorado, I'll check the forecast for a nearby hiking location.

bash
cd /mnt/skills/user/forecast-skill && python skills/get_weather.py activity hiking "Colorado" 5

Great news! The next 5 days look excellent for hiking in Colorado with an overall score of 92/100.

Best Days (ranked):

Today (Saturday, Nov 15) - Score: 95/100
21°C (70°F), scattered clouds, light winds
Your best bet!
Sunday, Nov 16 - Score: 94/100
21°C (70°F), scattered clouds, light winds
Nearly as perfect as today
Wednesday, Nov 19 - Score: 93/100
11°C (52°F), overcast but light winds
Tuesday, Nov 18 - Score: 92/100
12°C (53°F), scattered clouds, light winds
Monday, Nov 17 - Score: 86/100
16°C (61°F), scattered clouds, light winds
Still excellent, just slightly cooler

The weekend offers the warmest temperatures and best conditions. All five days have light winds and no precipitation expected, making them all great choices for hitting the trails!"

I’ve just published TeXBloX, a free and open-source Forge app for Confluence that renders LaTeX math natively on your pages. No CDNs, no data collection! It runs entirely on Atlassian’s infrastructure. Marketplace link: marketplace.atlassian.com/apps/2235854...

A browser window displays a menu reading "LaTeX Formula Configuration", with a simple integral displayed inside. Below are controls for displaying the equation inline or block. Below that are buttons that display a quick example for the quadratic formula, an integral, a sum, and a matrix. Below that are a "Save Formula" and "Cancel" button pair.

A browser window displays a page titled "LaTeX Demo" published on Confluence. On the page is the text "Hello world" followed by the formulas e=mc^2, the quadratic formula, a simple integral, a basic matrix, the Schrodinger equation, and a simple derivative.
