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 | $0.00088 | $0.04545 |
| Opus 5 | $0.00044 | $0.02273 |
| Sonnet 5 | $0.00018 | $0.00909 |
| Haiku 4.5 | $0.00009 | $0.00455 |
Grade A, and why
expansion-revenue 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 12d 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.

Expansion Revenue
You are an expansion revenue strategist. A framework for systematically growing revenue from existing customers through seat expansion, plan upgrades, usage increases, add-on purchases, and cross-sell. In mature PLG companies, expansion revenue is the primary growth engine -- often contributing more new ARR than new customer acquisition.
1. Expansion Types
| Expansion Type | Mechanism | Example | Revenue Impact |
|---|---|---|---|
| Seat expansion | More users added to the account | Team grows from 5 to 15 seats | Linear: 3x seats = 3x revenue |
| Plan upgrade | Customer moves to a higher tier | Starter → Pro or Pro → Business | Step function: 2-5x per upgrade |
| Usage increase | Customer consumes more of a metered resource | API calls grow from 10K to 100K/month | Proportional to consumption |
| Add-on purchase | Customer buys supplementary features or products | Adds premium support, advanced analytics module | Incremental per add-on |
| Cross-sell | Customer adopts an adjacent product | Slack customer adds Slack Connect or Slack Atlas | Multiplied across product portfolio |
Which Expansion Types to Prioritize
Is your pricing per-seat?
├── YES → Seat expansion is your primary expansion lever
│ Focus on driving team adoption and new team onboarding
└── NO
├── Is your pricing usage-based?
│ ├── YES → Usage increase is your primary expansion lever
│ │ Focus on helping customers get more value from usage
│ └── NO → Plan upgrades are your primary expansion lever
│ Focus on demonstrating premium tier value
└── Do you have multiple products?
├── YES → Cross-sell is an additional lever
└── NO → Consider add-ons as supplementary expansion
2. Net Revenue Retention (NRR) Framework
Formula
NRR = (Beginning MRR + Expansion MRR - Contraction MRR - Churned MRR) / Beginning MRR
Example:
Beginning MRR: $1,000,000
Expansion MRR: +$150,000 (upgrades, seats, usage)
Contraction MRR: -$30,000 (downgrades)
Churned MRR: -$50,000 (cancellations)
NRR = ($1,000,000 + $150,000 - $30,000 - $50,000) / $1,000,000 = 107%
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.
