What it does

Billing is an agent skill from theopenco/llmgateway. Organizations, plans, credits, and billing in LLM Gateway — org kinds, the Pro plan, DevPass and Chat entitlements, Stripe webhooks, end-user wallets, cost and token billing math, audit logs, and org-scoped emails and notifications. Use when changing apps/api/src/stripe.ts, subscription or credit logic, cost calculation, organization.kind or plan gating, DevPass status, auditlog actions, or any email or notification sent for an organization.

Its SKILL.md is about 670 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Backend & APIs, covering Model routing and gateways and Webhooks. It works with Stripe. The repository describes itself as: Route, manage, and analyze your LLM requests across multiple providers with a unified API interface.

When your agent uses it

  • Changing apps/api/src/stripe.ts
  • Cost calculation
  • Organization.kind
  • Auditlog actions

Example prompts

  • “/billing”

What it can do on your machine

Read from SKILL.md and the folder at commit 414b1b9. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Billing loads about 666 tokens when it runs. Until then it costs about 114 tokens; SKILL.md has 255 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~114
When it runs · the whole SKILL.md, loaded when a task matches
~666

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 255 words (~666 tokens).
