Skills library
Skills your second brain can run, as plain files. Download the folder once, drop it into your vault, and your AI has a menu of jobs it knows how to do. New skills ship weekly on this page; your own copy pulls them in when you ask.
- Download once. Put these files in a
skills/folder inside your second brain._INDEX.mdis the menu; your AI reads it every time, one line per skill. The skill files open only when a trigger matches. Small index, detail on demand. - Let the weekly review feed it. After your weekly review, the AI checks the index against the week you actually had and offers at most one matching skill. One, not five.
- It grows. The library here gets a new skill most weeks, each with a video. The
library-updateskill diffs this page's index against your local copy and reports what is new.
Start here
The menu and the contract. Two files that make every skill readable.
_INDEX.md The menu. One line per skill: trigger, what it does, requires, level. Your AI reads this file every time; a skill not listed here does not exist. Open → SKILL-FORMAT.md The fixed format every skill follows: 5 header fields, Steps written to the AI, an example run, and 2 or 3 ways to make it yours. Read this before writing your own. Open →Launch skills
Seven skills, complete and ready to run. Levels: Minimum (you understand it) · Optimum (it runs your week) · Expert (you build on it).
morning-brief.md Calendar, email and today's priorities in one brief under 200 words. Read only, runs on a schedule. OptimumOpen → weekly-review-focus.md Scores your week 0-10 per priority against real evidence, drafts your focus file update, then offers at most one skill for next week. MinimumOpen → gmail-weekly-email.md The week's inbox in 4 lists, replies drafted and labeled DRAFT. It never sends, never archives, without your OK per item. OptimumOpen → library-update.md Fetches this page's index, diffs it against your local copy, reports what is new, and never overwrites a skill you edited. MinimumOpen → system-audit.md Full read-only audit: auto-loaded files measured in tokens, every skill and tool tested live, security holes named, top 5 fixes. Run monthly on your strongest model. OptimumOpen → content-audit.md The librarian pass: one honest index per folder, constitution within its token budget, all 5 layers present. Proposes merge/archive/rewrite, changes nothing. MinimumOpen → graduation-check.md The verdict. Scores all 5 layers 0-100 with cited evidence, 3 binary gates, pass at 75 per layer. Completing the course = OPTIMUM from this skill plus your posted proof. MinimumOpen →Coming · one per video
Each ships as a set: the skill file, a deck, a short video. Your library-update skill will see them the week they land.
Write your own
The format is the contract. Copy the skeleton in SKILL-FORMAT.md, fill the 5 header fields, write the steps to the AI, add one line to your _INDEX.md. A job you have explained twice is a skill waiting to be a file.
