The file

We split this skill into the rules it gives an agent

4 rules. About 0 are common, 4 are distinctive, and 0 are very specific to this project.

  • ≈0

    Common · estimate

    Many files like this have a rule of this kind.

  • ≈4

    Distinctive · estimate

    This author's own choices. Worth a look.

  • 0

    Very specific

    Tied to their project's names, files or tools. Probably skip.

  1. Distinctive:

    Use this skill to validate usage-based billing before an invoice goes to the customer.

    line 8
  2. Distinctive:

    Do not assume internal, test, or failed usage is billable unless source policy says so.

    line 36
  3. Distinctive:

    Do not smooth or alter usage data without preserving the original source values.

    line 37
  4. Distinctive:

    Do not approve billing for unknown meters or unmapped customer IDs.

    line 38

≈ “Common” is an estimate: at least 1 in 5 of the 350,495 skill files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Keep what fits and drop the rest. Your version, ready for your agents.

Usage Billing Review

Use this skill to validate usage-based billing before an invoice goes to the customer.

Inputs

  • Usage export with customer ID, meter name, period, quantity, unit, and source timestamp.
  • Pricing terms, rate cards, tiers, included units, minimum commitments, and overage rules.
  • Draft invoice lines.
  • Known exceptions such as test accounts, internal usage, credits, outages, or contract overrides.

Workflow

  1. Confirm the billing period and customer identifiers match across usage, contract, and invoice data.
  2. Aggregate usage by billable meter and compare it with the invoice.
  3. Apply pricing rules in this order: included usage, credits, tiering, minimums, overages, discounts, and taxes if provided.
  4. Flag usage anomalies: sudden spikes, negative usage, duplicate records, missing days, unknown meters, and units that do not match the contract.
  5. Classify variances by customer impact and materiality.

Output

Return:

  • Billing readiness summary: ready, ready with minor cleanup, blocked, or requires approval.
  • Meter comparison table with usage quantity, billed quantity, expected charge, invoice charge, variance, and evidence.
  • Exception queue with owner and recommended resolution.
  • Customer-safe explanation for material usage variance when requested.

Guardrails

  • Do not assume internal, test, or failed usage is billable unless source policy says so.
  • Do not smooth or alter usage data without preserving the original source values.
  • Do not approve billing for unknown meters or unmapped customer IDs.
  • Escalate material variances before invoice release.

People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.

  • It worked
  • Partly
  • It didn't
What did you use it for? e.g. Reviewing pull requests in a Rails app

Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.
