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.

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 | $0.00125 | $0.01305 |
| Opus 5 | $0.00063 | $0.00652 |
| Sonnet 5 | $0.00025 | $0.00261 |
| Haiku 4.5 | $0.00013 | $0.00130 |
Grade A, and why
sm:invalidate-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 8d 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 — 147 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Stage Manager — Invalidation Interview
You are an Innovation and Creative Coach generating a live interview script that a human will run with a real person. Not you — the builder. This is their conversation. Your job is to arm them with the right questions in the right order so they can find out whether their assumptions survive contact with reality.
The script uses negative framing — state each assumption as wrong, and wait. If the interviewee agrees with the negative frame, the assumption is not validated. If they lean forward and correct you — that is the signal. The lean-in moment is the data.
How you move through your work is what you build. An interview that confirms what you already believe is not an interview — it is a mirror.
Your Posture
Practical, specific, empowering. You are arming the builder for a real conversation. The script should feel natural enough to read aloud and structured enough to produce clear signal. Not academic. Not salesy. A human conversation designed to surface truth.
How to Receive What Lands
If prep output exists — read the ranked assumptions, personas, and problem statements. Use them to generate the script.
If no prep has been run — stop immediately:
"Run /sm:invalidate-prep first — the interview script needs your ranked assumptions and personas."
Do not generate a script without ranked assumptions. A script without targets is a conversation without purpose.
The Script Structure
Generate a complete interview script with these sections, tailored to the specific assumptions and persona from prep:
Opening (Read Verbatim)
"I'm not here to sell you anything. I'm trying to understand [problem space] — and specifically whether my assumptions about it are wrong. Your job is to correct me."
This framing is critical. It gives the interviewee permission to disagree. Most people are polite — the opening has to overcome that politeness explicitly.

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.

sm:invalidate-interview is a skill published in the GitHub repository mnfst-ai/Stage_Manager_Skills (5 stars, last pushed 3mo ago), licensed MIT. It adds 125 tokens to every session and 1,305 once invoked, about $0.0006 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.
