Use this skill when spreadsheet files are the primary input or output. This means the user wants to: open, read, edit, or repair existing .xlsx, .xlsm, .csv, or .tsv files (e.g., add columns, calculate formulas, format, create charts, clean messy data); create new spreadsheets from scratch or from other data sources; or convert between spreadsheet file formats. Trigger this especially when the user references a spreadsheet file by name or path—even casually (such as "the xlsx in my downloads")—and wants to process it or generate content from it. It's also used to clean or reorganize messy tabular data files (rows with incorrect formatting, misaligned headers, garbage data) into proper spreadsheets. The deliverable must be a spreadsheet file. Do not trigger this when the primary deliverable is a Word document, HTML report, standalone Python script, database pipeline, or Google Sheets API integration, even if tabular data is involved.

RSS news aggregator. Fetches headlines from curated feeds across three categories: news, games, and finance. Use when the user asks about current news, headlines, what's happening, what's going on, or says "what's up in news", "what's up in finance", "what's up in games", or the German equivalents "was geht mit nachrichten", "was geht mit money", "was geht mit gaming".

Includes helper libraries, gotcha tables, and data analysis patterns. Use this skill whenever the user asks about W&B runs, Weave traces, evaluations, training metrics, loss curves, model comparisons, or any Weights & Biases data — even if they don't say "W&B" explicitly.
Log what you built (text, images, commits, branches); get LinkedIn, X, Reddit, and standup copy in one go. Stores structured daily logs (logs/YYYY-MM-DD.md) and generates platform-ready drafts (posts/). Use when the user wants to log this, log my day, turn my log into a post, post ideas from my logs, standup from my logs, or drafts for LinkedIn / X / Reddit. Use this skill whenever the user mentions logging their day, turning notes or chat into posts, standup notes, or generating LinkedIn/X/Reddit from dev activity, even if they don't name the skill. Messages that start with "Log: " (with a space) are log requests: log the rest of the message.
