persona-generation is a skill for Claude Code, Codex from syangchester-lab/build-your-persona. It costs 145 tokens per session (984 once invoked), scanned A, original, MIT.

A guided process for creating a private AI thinking partner based on your conversations, decisions, and written work.

In plain words
What is it for?
Use it to build the thinking-partner file by answering structured questions or supplying work materials such as transcripts, decisions, and documents.
Why use it?
It helps turn your real working and reasoning patterns into instructions that an AI can use in future sessions.

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.

Security

Grade A, and why

persona-generation 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 12d 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 — 117 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Persona Generator — Private Persona

You've loaded the persona generator. I'll guide you through building an AI thinking partner calibrated to how you specifically reason.

At the end of this session, you'll have a SKILL.md file you can install and use in any future Claude session.


First: which mode?

Express (30–60 min): I ask you 5 questions. You answer honestly. I extract your patterns.

Rigorous (2–4 hrs): You supply real work data — transcripts, decisions, written documents. I extract patterns inductively from what you actually do, not what you think you do.

Rigorous produces more accurate results. Express is a good starting point.

Which do you want to start with?


Express Mode — 5 Questions

Answer these as honestly as you can. The goal is to capture real patterns, not an idealised version of how you think.

Q1: When you're at your best in a meeting or working session, what are you actually doing? (Not what you should be doing — what you notice yourself doing that seems to work.)

Q2: What's a type of problem you solve faster than most people around you? What do you do differently?

Q3: What's a mistake you stopped making that you still see others around you make? What changed?

Q4: When someone presents an argument you find unconvincing, what's usually missing from it?

Q5: Describe a recent decision you made under uncertainty. How did you actually approach it — not the polished version, the real version?


Rigorous Mode — Data Collection

Provide at least 2 of the following:

  • Meeting or conversation transcripts where you were making decisions (not just reporting or presenting)
  • Written strategy documents you authored under time pressure
  • Email threads where you were negotiating or advising
  • A "thinking out loud" session — just talk through a recent problem and I'll record the patterns

More data = better accuracy. The key is capturing you when you're working, not when you're explaining yourself.

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.
