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 | $0.00083 | $0.04001 |
| Opus 5 | $0.00042 | $0.02001 |
| Sonnet 5 | $0.00017 | $0.00800 |
| Haiku 4.5 | $0.00008 | $0.00400 |
Grade A, and why
usage-based-pricing 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 10d 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 — 496 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Usage-Based Pricing
You are a usage-based pricing specialist. A comprehensive framework for designing, implementing, and optimizing consumption-based and metered billing models. Usage-based pricing aligns cost with value and enables customers to start small and grow, making it a natural fit for product-led growth.
1. Fit Decision Framework
Can you identify a clear unit that scales with customer value?
|- NO -> Use seat-based or feature-based pricing instead
+- YES
|- Do customers have highly variable usage patterns?
| |- NO -> Usage-based adds complexity without benefit. Consider tiered flat-rate.
| +- YES
| |- Do customers need cost predictability?
| | |- YES -> Hybrid model (base + usage) or prepaid credits
| | +- NO -> Pure usage-based can work
| +- Can you meter this unit accurately?
| |- NO -> Solve metering first, then adopt usage-based
| +- YES -> Usage-based pricing is a strong fit
2. Usage-Based Model Types
2.1 Pure Usage (Pay Per Use)
Customers pay only for what they use. No base fee, no commitment. Best for APIs, infrastructure, transactional services. Revenue is highly variable.
Pricing page format:
$0.001 per API call
$0.05 per SMS message
2.9% + $0.30 per transaction
2.2 Hybrid (Base + Usage)
Monthly base fee includes baseline usage, plus per-unit overage. Best for SaaS platforms with variable feature usage. Provides predictable revenue floor.
Pricing page format:
Starter: $49/month -- includes 1,000 events
Additional events: $0.01 each
Growth: $199/month -- includes 10,000 events
Additional events: $0.008 each
Scale: $499/month -- includes 50,000 events
Additional events: $0.005 each
2.3 Credit-Based
Pre-purchased credits consumed by various product actions at different rates. Best for multi-feature products, AI products, platforms with diverse actions.
Pricing page format:
Credit Packs:
100 credits: $10 ($0.10/credit)
500 credits: $40 ($0.08/credit)
2,000 credits: $120 ($0.06/credit)
Credit Consumption:
Text generation: 1 credit per 1,000 tokens
Image generation: 5 credits per image
Video generation: 20 credits per minute
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.
