customer-interview is a skill for Claude Code from TimboGP/timbogp-marketplace. It costs 159 tokens per session (1,361 once invoked), scanned A, original, MIT.

A practice and preparation tool for customer-development interviews. These are structured conversations used to learn whether a real customer has an important problem, likes a proposed solution, or would use a first version.

In plain words
What is it for?
Use it to practise problem interviews, solution interviews, or MVP interviews, or to prepare and critique your interview questions.
Why use it?
It helps you rehearse realistic conversations and spot weak interview habits before speaking to real people. The follow-up review connects the conversation to the assumptions you need to test.

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

customer-interview 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 11d 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.

Customer interview

The heart of customer development: talk to real people to validate (or kill) your assumptions before building. This skill lets the user rehearse those conversations against a believable customer and get coached on technique — or just prep the scripts. You play the Customer role-play role (../../reference/roles.md) under the shared role-play protocol. Read references/interview-scripts.md for the three scripts before running.

When to use

The user wants to run, practice, or prep a customer interview. Three flavors map to the methodology's stages (../../reference/methodology.md):

Flavor Stage Tests Exit criteria
Problem Understand Problem Is this a must-have problem? For whom? Vs. what existing alternatives? ≥10 interviews; can identify early-adopter demographics; have a must-have problem; can describe how customers solve it today
Solution Define Solution Does the smallest solution (a demo/mock-up) excite them? Will they pay? Early adopters who'd rather buy than build; a price they accept; a defined Release 1.0
MVP Validate Qualitatively Does the live MVP get noticed, activate, deliver the UVP, and convert to paid? Warm prospects sign up and complete activation; usability hot spots found

If the user hasn't picked a flavor, infer it from their stage in .lean/PROGRESS.md and propose one.

Two modes

  • Prep mode — the user wants scripts, demographic-qualifying questions, or a critique of their own script. Provide them from references/interview-scripts.md, tailored to their canvas. No role-play.
  • Role-play mode (default when they say "play a customer") — run the role-play protocol below.

Role-play protocol (Customer)

Follow the three-phase protocol in ../../reference/roles.md. Flavor-specific points:

Phase 0 — Set up (out of character)

  1. Confirm flavor (problem/solution/mvp), the format ("a ~20-minute problem interview; you interview me"), and that you'll stay in character until they say debrief (or break with [square brackets]).
  2. Build the persona from .lean/canvas.md (Customer Segment + Early Adopter) — or invent a realistic one and confirm it: a name, situation, how they handle the problem today (their existing alternative), constraints, and an attitude (busy, skeptical, enthusiastic-but-flaky…). Note privately their hidden truths — e.g. they say a problem matters but haven't acted on it — for the debrief.
  3. Announce entering character.

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.
