invoice

A command for preparing a draft invoice from tracked work hours or specified items for someone to approve.

In plain words
What is it for?
Use it to preview an invoice, bill unbilled timer entries, add fixed line items, or combine hours and items on one draft invoice.
Why use it?
It lets you check totals, rates, and duplicate billing before creating the draft. The invoice is not sent automatically.

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.

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 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 yesterday.

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

Task

Propose an invoice for $ARGUMENTS. Always dry-run first:

billing invoice new $ARGUMENTS --dry-run --json

Show the user what it would create. Only run it again without --dry-run when they have said to.

Line items come from --from-timer (tracked hours), from --item "Description|quantity|price", or both on the same invoice.

Rules

  • Creating an invoice is a business action. Do not write one unprompted. --dry-run builds and validates the entire invoice — the rate lookup and the double-billing check included — so a dry run that succeeds means the real one will. There is no reason to skip it.
  • A new invoice is a draft. billing invoice mark <n> sent is a separate, deliberate step and this tool never emails anything. Do not mark an invoice sent or paid unless the user asked.
  • Read amounts (decimal) when talking to a person; the bare total is in minor units.
  • Exit 3 on --from-timer means there were no unbilled hours. Check billing hours and report skipped.running rather than concluding there is nothing to bill.
  • The same hour cannot reach two invoices: each invoice records the timer entry ids it covers. If the user wants to re-bill something, voiding the old invoice releases those hours.
  • Prefer billing invoice render <n> --format html --out <file> when they want something to send: it is one self-contained file that prints to PDF.

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.

invoice is a command published in the GitHub repository moshcoder/moshcode (2 stars, last pushed yesterday), licensed MIT. It adds 17 tokens to every session and 430 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
