invoice-client

invoice-client is a command for coding agents from protomated/protomated-plugins-official. It costs 13 tokens per session (480 once invoked), scanned A, original, Apache-2.0.

A command that finds a client's unbilled time entries, shows what will be included, and marks them as billed after confirmation. Billing means recording that work has been included in an invoice.

In plain words
What is it for?
Use it when preparing an invoice for a client in the Legal Billing system connected to Google Sheets.
Why use it?
It helps prevent unbilled work from being missed and provides a review step before entries change to billed status.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

invoice-client 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 3d 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

End-to-end invoice flow: show unbilled work, confirm, then mark as billed.

Invocation

/legal-billing:invoice-client $ARGUMENTS

$ARGUMENTS should be the client name. If missing, ask: "Which client are you invoicing?"

Workflow

Step 0 — Confirm setup first: Call connect_google with check_only: true. If not connected, stop and tell the attorney to say "connect Google" — do not ask for a client name yet. If connected, proceed; if the first data call below returns "No Google Sheet configured yet", stop and ask whether to create a new sheet from the template (create_billing_sheet, only after they confirm) or connect an existing one (set_spreadsheet_url). Only continue once both are confirmed. If you call create_billing_sheet, always paste the full sheet URL from its result into your reply — do not just say "sheet created."

Step 1 — Pull unbilled entries: Call get_time_entries with clientName and status: Unbilled.

If no unbilled entries: "No unbilled time found for [client]. Nothing to invoice." Stop here.

Step 2 — Show what will be invoiced: "Here's what I'll mark as billed for [client]:

Date Matter Hours Rate Fee
[row] ... ... ... $...

Total: $[X] across [N] entries.

Ready to mark all of these as billed with today's invoice date?"

Step 3 — Wait for confirmation, then call mark_billed.

Step 4 — Report success: "✅ Done. All [N] entries for [client] marked as Billed — invoice date set to today ([date]). ⚠️ Not legal advice — review before sending to client."

Step 5 — Preview invoice (optional): "Want me to pull the invoice preview? Say 'show invoice' and I'll read the Invoice tab."

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.
