What is second-brain-setup?

A guided setup for creating or refreshing a product builder’s personal profile in a file called 8-System/about.md. It can use personality or strengths assessments, an interview, or both.

Use it when setting up a new knowledge vault, after a role or project change, or when the agent needs recalibrating.

It gives the agent written context about how to work with the person, reducing advice that feels out of step with their preferences, strengths, or current priorities.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00041	$0.01020
Opus 5.5	$0.00016	$0.00408
Sonnet 5.5	$0.00008	$0.00204
Haiku 4.5	$0.00004	$0.00102

Security

Grade A, and why

second-brain-setup scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 114 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Second Brain Setup

Purpose

Runs a conversation with the product builder and writes the result to 8-System/about.md. That file tells the agent who the human is, how they want to be treated and where they need to be pushed. It works as a pair with 8-System/brain.md, which holds the universal operating rules.

When to use

Setting up a new vault for the first time
Refreshing the profile after a role change, a new project or a shift in priorities
When the AI feels "out of calibration"

How it works

Step 0: Pick a path

Ask:

There are two ways for me to get to know you:

A) I have assessment results - paste your CliftonStrengths (Gallup), DISC, MBTI, 16Personalities, Enneagram, Working Genius or any other personality/competency assessment. I will pull out the parts that change how we work together.

B) Let's talk - I will run a short interview (5-7 minutes).

You can do both: start with the assessment, then fill the gaps by talking.

Path A: Assessment-first

Read the pasted results
Extract ONLY operational information - the parts that change how the AI works:
- Strengths -> how the AI should frame recommendations
- Weaknesses and blind spots -> where the AI should actively push
- Communication style -> how the AI should speak
- Decision style -> how the AI should present options
Do NOT copy the full report into about.md. The extract is 5-8 bullets in the "How to work with me" section
Ask short follow-up questions about what the assessment does not cover:
- Current role and context (Q1 from references/questions.md - short version, 2-3 sentences is enough)
- Six-month goal (Q4 from references/questions.md)
Go to Step 3 (proposal)

Path B: Interview

Ask the questions in references/questions.md in order: Q1 (Context), Q2 (Communication style), Q3 (Development areas), Q4 (Goals)
Rules:
- Q1: all six sub-questions in one block, one answer
- Q2.1-Q2.5: five multiple-choice questions, one at a time
- Q3: multi-select, 2-3 from a list of 8
- Q4: one open question
Go to Step 3 (proposal)

What ships with it

5 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
