Summary

This one walks you through GCC flag selection for different build modes: debug with `-g -Og`, release with `-O2` or `-O3 -march=native`, size-optimized with `-Os`, and sanitizer builds. It covers LTO and PGO workflows step by step, warning flag discipline with `-Wall -Wextra`, and a triage table for common errors like undefined references and ABI mismatches. The optimization decision tree is practical, especially the note that `-O3` can regress performance due to instruction cache pressure. If you've ever second-guessed whether to enable `-flto` or wondered why `-Ofast` broke your floating point math, this gives you the exact invocations and explains the tradeoffs without the usual compiler flag folklore.

diversification

joellewis/finance_skills

Build diversified portfolios using correlation analysis, efficient frontier construction, and factor-based diversification. Use when the user asks about portfolio variance, correlation effects, the efficient frontier, minimum variance portfolios, diversification ratios, or factor diversification. Also trigger when users mention 'don't put all eggs in one basket', 'how many stocks do I need', 'correlation breakdown in a crisis', 'are my holdings really diversified', 'risk contributions', or ask why diversification fails during market crashes.

artist-workspace

recoupable/skills

How to work in artist directories — including creating, enumerating, and editing them. Use when creating or onboarding a new artist ("create artist", "onboard X", "add this artist", "set up a new artist") — this skill scaffolds the artist's `RECOUP.md` checklist file and drives the multi-step setup from it. Use when adding or updating artist context (identity, brand, voice, audience), adding songs, organizing files inside an artist directory, or figuring out where something belongs. Also use when the account asks inventory questions like "what artists do I have", "list my artists", "which orgs am I in", "what's in this sandbox" — the filesystem tree is the authoritative answer. And use when the account mentions an artist by name and the task involves their files, context, or content — even if they don't say "artist directory." This includes tasks like researching an artist, creating content for an artist, updating an artist's brand, or adding a face guide.
