Use it to review active subscriptions, group customers by upgrade opportunity, estimate potential increases, and assess NRR.
Why use it?

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

upsell-expansion 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 2mo 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.

What it actually says

Upsell & Expansion

Stripe MCP Setup

Requires Stripe MCP (https://docs.stripe.com/mcp). GetMcpTools before CallMcpTool. Paginate all lists (limit: 100, starting_after while has_more). Amounts in cents. Read-only for audits; confirm before writes.

Workflow

  1. List active subs with items expanded
  2. Segment:
    • Single-plan subs -> upsell to higher tier / add-ons
    • Users near usage/seat limits (if metadata tracks it)
    • Long-tenure subs on legacy low prices
  3. Compute NRR = (start MRR + expansion - contraction - churn) / start MRR

Output Template

Expansion Opportunities

NRR (last period): [X]% (benchmark: >100% is expansion-positive)

| Segment | Subs | Current MRR | Upsell path | Est. uplift |
|---------|------|-------------|-------------|-------------|
| No add-on | | | Agent add-on | |
| Starter 12mo+ | | | -> Pro | |

Priority: [highest-uplift, lowest-friction segment]

Cross-check add-on attach rate against pricing-products-audit.

Changes

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.
