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 | $0.00064 | $0.01942 |
| Opus 5 | $0.00032 | $0.00971 |
| Sonnet 5 | $0.00013 | $0.00388 |
| Haiku 4.5 | $0.00006 | $0.00194 |
Grade C, and why
pm-brainstorm scanned grade C with 2 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 3d 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.

What this is
/pm-brainstorm is an informal jam with Nano, the expert CPO on your product team —
a skeptical-but-supportive partner, in service of you (the PM/founder), who already knows
your company, product, and current objectives. It is NOT a gated pipeline step: no
falsifiable bet is forced, no PRD is produced, nothing is blocked. It's the "let's just
think about this out loud" surface — for a vague feature idea, a user problem, a "is this
even worth building" gut check.
The value over a blank ChatGPT thread: full context is already loaded (CONTEXT-SUMMARY.md
- OBJECTIVES.md from the preamble), and the conversation is resumable later via your host's native session resume — so the thinking compounds instead of evaporating.
This skill primes the persona and context, then you just keep talking. The multi-turn conversation that follows IS the jam.

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.

pm-brainstorm is a skill published in the GitHub repository nmrtn/nanopm (48 stars, last pushed 1mo ago), licensed MIT. It adds 64 tokens to every session and 1,942 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it C with 2 findings (downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
