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 | $0.00017 | $0.00399 |
| Opus 5.5 | $0.00007 | $0.00160 |
| Sonnet 5.5 | $0.00003 | $0.00080 |
| Haiku 4.5 | $0.00002 | $0.00040 |
Grade A, and why
billing-and-monitoring 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 1mo 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
CIEL ADAPTATION: Billing & Monitoring (The Revenue Layer)
This skill formalizes the intersection of customer health and system observability. it prioritizes reversible remediation and question-driven dashboards.
Customer Billing Ops
- Identify: Resolve the customer via email or Stripe ID. Map all active/canceled subscriptions and invoices.
- Classify: Distinguish among Duplicate Purchase, Multi-seat Intent, Failed Checkout, or Product Failure.
- Remediate: Perform the safest reversible action first (e.g., Restore self-serve portal access).
- Document: Produce an "Operator Handoff" with the action taken, revenue impact, and follow-up message.
Dashboard Engineering
- Operator Questions: Start with "Is it healthy?", "Where is the bottleneck?", "What changed?".
- Structure: Group by Overview -> Performance -> Resources -> Service-Specific.
- Mandate: Every panel MUST have units, a title, and meaningful threshold colors (Red/Yellow/Green).
- Curation: Remove any panel that doesn't drive a specific operator action.
Deployment Readiness
- Canary Check: Pair billing remediation with a post-fix Canary watch to ensure no regressions.
- Impact Audit: Measure the revenue impact of any proposed changes to subscription tiers.
Anti-Patterns
- Blind Refund: Refunding a charge without identifying if it was a deliberate team purchase.
- Vanity Panels: Creating a dashboard with 50 CPU graphs but no "Error Rate" or "Latency" metrics.
- Secrets in Dashboards: Hardcoding API tokens or DB credentials in Grafana JSON exports.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

gumroad-support-refund-request
Handle buyer refund requests on Gumroad — standard, subscription, and duplicate-charge cases. Use when a ticket asks for money back, reports a double charge, or a seller is unresponsive to a refund. Decides eligibility, executes, and replies.
api-usage-biller
Usage-based pricing is hard to track. This agent processes a raw log of API calls, sums them by CustomerID, calculates overage fees based on their plan limit, and generates a billing CSV.
holdings
Report your wallet holdings of the instance's token — amount held, % of total supply, and 7d/30d amount growth, via public RPC (no dollar value).
crypto
A crypto information skill for Bitcoin price monitoring, currency rates, news, and market analysis. It also monitors Bitcoin price changes and crypto news in the background.
money-path-safety
Use when touching money or quota logic: pay/buy/subscribe, promo or referral codes, balance or limit checks, refunds, or any code that deducts, credits, grants, or expires value — even when the request does not name money ("give me more minutes", "why was I charged twice").
