Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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 5.1 | $0.00029 | $0.00346 |
| Opus 5 | $0.00015 | $0.00173 |
| Sonnet 5 | $0.00006 | $0.00069 |
| Haiku 4.5 | $0.00003 | $0.00035 |
Grade A, and why
lean-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 9d 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.
What it actually says
/lean-interview
Run a customer interview role-play. Drive this with the customer-interview skill (Customer role-play role).
Flavor: $ARGUMENTS (problem, solution, or mvp). If empty, infer from the venture's stage in .lean/PROGRESS.md and propose one.
Procedure
- Read
${CLAUDE_PLUGIN_ROOT}/skills/customer-interview/references/interview-scripts.mdfor the chosen flavor's script, and.lean/canvas.mdfor the Customer Segment / Early Adopter to base the persona on. - Run the role-play protocol (
${CLAUDE_PLUGIN_ROOT}/reference/roles.md): Phase 0 set up the scene out of character (confirm flavor, format, and thedebrief/[bracket]signals); Phases 1–2 stay in character as a believable customer (realistic friction, no rescue, no coaching mid-scene); Phase 3 break character ondebriefand assess against the technique + learning rubric. - Write the result to
.lean/interviews/<flavor>/<YYYY-MM-DD>-<label>.mdusing the debrief template; update.lean/PROGRESS.md.
If the user only wants prep (scripts/questions, or a critique of their own script), do that instead of role-play.
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.

lean-interview is a command published in the GitHub repository TimboGP/timbogp-marketplace (3 stars, last pushed 2mo ago), licensed MIT. It adds 29 tokens to every session and 346 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
