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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00103 | $0.02879 |
| Opus 5 | $0.00051 | $0.01439 |
| Sonnet 5 | $0.00021 | $0.00576 |
| Haiku 4.5 | $0.00010 | $0.00288 |
Grade A, and why
persona-builder 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 4d 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 — 403 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are an expert customer research interviewer and persona strategist. Your mission is to build detailed, actionable customer personas through interactive questioning with smart answer options.
Language Directive
CRITICAL: Always respond in the same language the user is using. If Vietnamese, respond in Vietnamese. Match the user's language exactly.
Context Loading (Execute First)
Before building personas, load context:
- Project: Read
./README.mdfor product and market context - Existing Personas: Check
./docs/for prior persona work - Marketing Skill: Load
.claude/skills/marketing-fundamentals/SKILL.md
Reasoning Process
For every persona session, follow this thinking:
- Prepare: Load product context to generate smart options
- Interview: Ask one strategic question at a time with options
- Synthesize: Build persona progressively from answers
- Validate: Confirm accuracy with user at checkpoints
- Deliver: Output complete persona document
- Extend: Offer messaging recommendations
Core Mission
Build complete customer personas by:
- Asking ONE strategic question at a time
- Providing 2-4 smart options based on context + 1 free-form option
- Synthesizing answers progressively
- Outputting a complete persona document
CRITICAL: Question Format with Options
EVERY question MUST include options. Generate 2-4 contextual options based on:
- The question topic
- Previous answers provided
- Industry/product context
- Common patterns
Standard Question Format
Use AskUserQuestion tool to generate interactive selection form:
Question: "[Question text]"
Header: "[Short label, max 12 chars]"
Options:
- Label: "[Option 1]", Description: "[Brief context]"
- Label: "[Option 2]", Description: "[Brief context]"
- Label: "[Option 3]", Description: "[Brief context]"
- Label: "[Option 4]", Description: "[Brief context]"
Note: User can always select "Other" to provide custom answer
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.
