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 | $0.00020 | $0.00392 |
| Opus 5.5 | $0.00008 | $0.00157 |
| Sonnet 5.5 | $0.00004 | $0.00078 |
| Haiku 4.5 | $0.00002 | $0.00039 |
Grade A, and why
billing-and-burn-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 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 & Burn Ops (The Value Layer)
This skill formalizes the auditing of system costs and revenue integrity. it prioritizes code-backed truth and identifying high-burn failure patterns.
Burn Auditing (ECC Tools)
- Trace Ingress: Map every webhook -> queue -> worker path before suggesting fixes.
- Recursion Risk: Treat app-generated branches/PRs as priority-0 recursion risks.
- Premium Leakage: Verify if capped/free users are hitting premium analyzers (e.g., Opus).
- Retry Burn: Fix deterministic failures that waste tokens on repeated non-transient errors.
Revenue & Pricing Truth
- Paid Sales: Rely ONLY on live billing data or timestamped snapshots.
- Product Truth: Inspect the entitlement code path. PROHIBIT assuming "team billing" exists just because it's in the marketing copy.
- Customer Impact: Distinguish between accidental duplicates and deliberate multi-seat intent before refunding.
Decision Format
Every audit MUST end with:
- Snapshot: Timestamped revenue/anomalies.
- Product Truth: What the code actually does vs marketing claims.
- Decision: Refund, Preserve, or No-op.
- Gap: The exact backlog item required to fix the workflow.
Anti-Patterns
- Diagnosis via Marketing: Claiming a feature works because it's on the landing page.
- Refund-First: Refunding without classifying the issue, losing valuable intent data.
- Expensive Failure: Spending $50 in tokens only to fail on a file-push conflict.
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").
