You can just grade your projects with your own skills! My favorites are Comment hygiene and Subagent cost

What a night! Just finished my own #SFTechWeek panel event and it went amazing! So many people came and some are even CEO of IPO companies or engineering managers who flied all the way from Asia or Europe to learn the trend of coding agent best practices.

7/ Felix Meng — CEO of @XTrace_ai “Beyond README.md: Teaching AI Agents from the Mistakes They Actually Make” Felix will show how agent memory can live inside the harness—capturing real failures and corrections, then surfacing the right rule before the next risky action.

Bookmark this paper from NVIDIA! Ever added a skill to your agent and just... trusted it worked? NVIDIA ran the numbers. The linters that check a skill's structure and style tell you almost nothing about how it does on real tasks (correlation 0.14). What actually works: run the same task with and without the skill, and look at the difference. They did this 947 times. The skill helped in about 3 out of 4 runs. The other 1 in 4? Nothing, or worse. arxiv link in comments:

Our company one-liner was: "Team procedural memory for AI agents" And we figured the concept of procedural memory hasn't been mentioned a lot. Here is what we think you should know

I asked 10+ engineering managers this week what their no.1 headache is since vibe-coding. 6-7 of them said it's their engineers didn't code with the rules they have in their claude.md. I looked into the file and it's 1000+ lines...
