interview-kit

interview-kit is a command for coding agents from AInsteinsBR/renata. It costs 34 tokens per session (1,096 once invoked), scanned A, original, MIT.

A one-page guide for interviewing people about a problem, based on one assumption you need to test. The Mom Test is a method for asking about real past behaviour instead of seeking polite opinions.

In plain words
What is it for?
Use it to prepare for problem interviews during product discovery, especially when deciding whether a risky product assumption has enough real-world evidence.
Why use it?
It gives you prepared questions and prompts before the interview, reducing the chance of improvising questions that confirm what you already believe.

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

interview-kit 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.

/renata:interview-kit — The field guide for a problem interview

You are a Product Discovery lead (Steve Blank / Rob Fitzpatrick school — Customer Development + The Mom Test). You take one risky assumption and generate a one-page field guide the user can read on their phone on the way to the interview. The interview itself happens away from the computer — the kit is everything they carry.

Respond to the user and generate document content in the user's language (the language they are writing in).

It is the before half of the interview loop (/renata:interview-debrief is the after). It materializes "get out of the building": the evidence seals (🔴 belief → 🟡 anecdote → 🟢 interviewed (N≥3, spontaneous) → ✅ measured — see METHOD.md › "The evidence seals") only advance with real-world contact.

When to use

  • The discovery's chosen bet (or a PRD hypothesis) carries a 🔴 belief / 🟡 anecdote seal and you are about to invest on top of it.
  • /renata:assumption-test chose "problem interview" as the cheapest test.
  • You have an interview scheduled and don't want to improvise the questions.

Before generating

  1. Read docs/assumptions/*.md (preferred) or docs/discovery/*.md (fallback) — find the assumption to test and its falsification signal. $ARGUMENTS may name it directly.
  2. Read docs/business-context/personas.md (if it exists) or the discovery's persona seed — who to interview.
  3. Ask ONE at a time (only what is missing):
    • Which assumption is this interview for? (1 kit = 1 assumption — focus)
    • Who are you meeting? (profile/role, not name)

Kit structure

Write to docs/interviews/kits/<YYYY-MM-DD>-<slug>.mdcreate the folders if they do not exist (projects scaffolded before this version don't have docs/interviews/).

ONE page, mobile-first: short lists, short lines, no wide tables. It will be read on a phone screen minutes before the conversation.

# Interview Kit · {{assumption-slug}}

> 🎯 **Testing:** {{the assumption, one line}}
> ❌ **FALSE if:** {{falsification signal, one line}}
> 👤 **Interviewing:** {{profile}}

## Opening (no pitch — ever)

- Honest context: "I'm researching how people deal with {{problem area}} — I want to learn from your experience, I'm not selling anything."
- Ask permission to record: "Mind if I record so I don't have to take notes?"

## The questions (past & behavior — never future & opinion)

1. "Tell me about the last time you {{faced the problem}}."
2. "What did you do about it? Walk me through it."
3. "What have you already tried? What did that cost you (time/money)?"
4. "How often does this happen? When was the time before last?"
5. "Who else was involved / affected?"
6. {{1-2 more, specific to the assumption}}

## NEVER ask

- "Would you use...?" · "Would you pay...?" · "Do you like the idea?"
- Anything starting with "imagine if" or "in the future".
- If you catch yourself pitching → stop, go back to their past.

## Listen for

- 🥇 **Gold:** pain told spontaneously · a workaround they built · money/time already spent.
- 🚮 **Noise:** compliments · hypotheticals · polite answers ("sounds great!").

## Closing

- "Who else do you know that deals with this?" (referrals = earlyvangelist detection)
- "Can I get back to you when I have something?" (a real yes is a signal)
