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

pmf-strategy 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 7d 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.

Strategies: Product-Market Fit

Guides product-market fit (PMF) validation and measurement. PMF occurs when a product precisely meets market needs, creating widespread demand. ~99% of startups fail primarily due to PMF issues (vitamin problems, premature scaling). Use this skill when validating before scaling, measuring PMF, or diagnosing traction problems.

When invoking: On first use, if helpful, open with 1–2 sentences on what this skill covers and why it matters, then provide the main output. On subsequent use or when the user asks to skip, go directly to the main output.

Definition

Product-market fit (Marc Andreessen): "Being in a good market with a product that can satisfy that market."

Signals: Customers buying rapidly; usage growing; word-of-mouth spreading organically; high retention, low churn.

Sean Ellis 40% Test

Question: "How would you feel if you could no longer use [product]?"

Response Meaning
Very disappointed Strong PMF signal
Somewhat disappointed
Not disappointed
N/A – I no longer use

Threshold: 40%+ answering "very disappointed" = PMF achieved. Below 40% = iterate.

Score Action
Below 25% Significant changes needed
25–39% Close to PMF; iterate and improve
40%+ PMF achieved

Best practice: Survey 40–50 active users (used product 2+ times in last 14 days). Segment by user type—some segments may have PMF while others don't.

Limitation: Combine with retention curves, engagement, organic growth; avoid false positives in early stages.

Vitamin vs Painkiller

Type Definition Adoption
Painkiller Solves urgent, acute problems; users actively seek solutions Fast adoption; high retention; willing to pay
Vitamin Nice-to-have; incremental benefit; users can live without Slow adoption; expensive marketing to succeed

~99% of failures: Solving vitamin problems instead of real pain. Validate: Would users be genuinely inconvenienced if your product vanished?
