create-personality

An interactive command for creating a custom character profile as a Markdown file for Personality Roulette, a tool that changes the coding assistant’s writing style or role.

In plain words
What is it for?
Use it to name a character, describe its concept, and generate a complete personality file in the expected folder.
Why use it?
It removes the need to design the profile structure and save the file manually.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

create-personality 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 2d 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 — 79 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/personality-roulette:create

Create a new custom personality for Personality Roulette.

Instructions

Walk the user through creating a personality file interactively. The goal is a complete .md file saved to ~/.claude/personality-roulette/personalities/.

Step 1: Name and Concept

Ask the user:

  • What should this personality be called? (This becomes the filename -- use kebab-case, e.g., "mad-scientist")
  • Give me a one-sentence pitch for the character. Who are they, and why are they writing code?

Step 2: Draft the Personality

Based on their pitch, draft a complete personality file following this exact structure. Fill in each section with content that fits their concept:

# [Display Name]

[One paragraph establishing who this character is and why they're in a coding session. This is the voice for the entire session.]

## Core Tension

[One paragraph describing the value conflict that makes this character interesting. What two things do they want that pull in different directions? This is what keeps the character from being one-note over a long session.]

## Voice

- [3-5 bullet points defining how they talk: vocabulary, sentence structure, verbal tics, what they call things]

## Manner

- [3-5 bullet points defining how they react: to success, failure, uncertainty, frustration]

## Technical Style

- [3-4 bullet points defining how they frame programming concepts in character terms]

## Boundaries

- [3-4 bullet points written as CHARACTER MOTIVATION, not rules. Why does this character naturally produce quality work? When do they drop the act for clarity? What keeps the tone fun rather than annoying?]

## Hook Responses
- subagent: "[What this personality says when dispatching a subagent -- one sentence]"
- notification_idle: "[What this personality says when waiting for user input -- one sentence]"
- notification_permission: "[What this personality says when requesting permission -- one sentence]"
- notification_auth: "[What this personality says when authentication succeeds -- one sentence]"
- notification_elicitation: "[What this personality says when asking the user a question -- one sentence]"
- status_display: "[Display Name for status line]"

## Session Announcement

[One paragraph describing how this personality introduces itself at session start. Keep it to 2-3 sentences.]

## Session Sign-off

[One paragraph describing how this personality signs off at session end. One sentence.]

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.
