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 | $0.00042 | $0.01093 |
| Opus 5 | $0.00021 | $0.00547 |
| Sonnet 5 | $0.00008 | $0.00219 |
| Haiku 4.5 | $0.00004 | $0.00109 |
Grade A, and why
customer-billing-ops 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 9d 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.

Customer Billing Ops
Manage the full subscription lifecycle from signup through renewal, including the hard parts: downgrades, cancellations, refunds, and churn prevention.
Subscription Lifecycle
New Subscription
- Confirm plan selection, billing cycle (monthly/annual), and payment method
- Set the billing anchor date (first of month, signup date, or custom)
- Document trial period length and conversion trigger
- Record in the customer record: plan, start date, billing cycle, MRR contribution
Upgrade
- Calculate prorated amount for the remaining billing cycle
- Confirm the upgrade with the customer (new price, effective date, prorated charge)
- Update the subscription record: new plan, effective date, new MRR
- Trigger a confirmation email with the updated invoice
Downgrade
- Determine effective date (immediate or end of current cycle)
- Calculate credit or refund for unused portion if immediate
- Confirm feature access changes with the customer
- Update the subscription record: new plan, effective date, adjusted MRR
- Flag the account for a check-in 30 days after downgrade
Renewal
- Send renewal reminder 14 days before the billing date
- Verify payment method is still valid
- Process the charge on the billing date
- Handle failed payments: retry schedule (day 1, 3, 7), dunning emails, grace period
Churn Triage
Identify At-Risk Accounts
Look for these signals:
- Usage dropped >50% in the last 30 days
- Support tickets increased without resolution
- Key user (admin/champion) left the company
- Downgrade request submitted
- Payment failed and not recovered after first retry
- No login in 21+ days
- Competitor mentioned in support conversations
Build a Save Offer
Match the save offer to the reason for leaving:
| Reason | Save Offer |
|---|---|
| Too expensive | Offer annual discount, downgrade to lower tier, or pause billing |
| Not using it enough | Offer onboarding session, extend trial, or reduce to essentials plan |
| Missing feature | Document the request, share roadmap timeline, offer beta access |
| Switching to competitor | Ask what they offer that you do not, document for product team |
| Budget cut | Offer 3-month pause instead of cancellation |
| Bad experience | Escalate to senior support, offer service credit, schedule a call |
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.
