## Tools (as reported by the server, not verified)

- `list\_invoices`: List the signed-in freelancer's invoices. Use a returned id with read\_invoice. Do not guess an invoice.
- `begin\_invoice`: Start a draft invoice. Draft figures are not an approved commitment until seal\_invoice. Currency is a three-letter code. Amounts later are minor units of that currency and are the freelancer's figures.
- `read\_invoice`: Read the invoice before answering. Quote only this record. Draft status is not an approved commitment. Proposed changes do not authorize a new line, a different rate, a discount, or a new due date.
- `place\_line`: Add one line: description, quantity, rate in whole minor units, and unit hour, each, or day. After the invoice is sealed, a new line is refused until accept\_invoice\_change applies an add\_line suggestion.
- `describe\_line`: Correct a line description while the invoice is still a draft. After approval, a different description is refused. Use suggest\_invoice\_change with add\_line for a different line.
- `quote\_line\_rate`: Set the rate already chosen for one line, as a whole number of minor units in the invoice currency. After the invoice is sealed, a different rate is refused until accept\_invoice\_change applies a change\_rate suggestion.
- `set\_line\_quantity`: Set the quantity on one line. After the invoice is sealed, a different quantity is refused until accept\_invoice\_change applies an adjust\_quantity suggestion.
- `set\_invoice\_due`: Set the due date as a calendar day in YYYY-MM-DD form. After the invoice is sealed, a different date is refused until accept\_invoice\_change applies a move\_due\_date suggestion.
- `write\_late\_terms`: Record late terms: grace days, and a basis of none, flat\_fee, or percent\_per\_period. flat\_fee uses feeMinor and a percent of 0. percent\_per\_period uses percent and a fee of 0. After approval, a different basis, grace, fee, or percent is refused until an accepted revise\_late\_terms suggestion.
- `offer\_discount`: Record a discount the freelancer is putting on the invoice. kind none uses value 0. kind percent takes a whole number from 1 to 100. kind fixed takes a whole number of minor units. After the invoice is sealed, a different discount is refused until accept\_invoice\_change applies an apply\_discount sugg
- `seal\_invoice`: Mark the current draft as the approved invoice. Pass confirmed true only after the freelancer explicitly approves the lines, quantities, rates, due date, late terms, and any discount already on the draft.
- `suggest\_invoice\_change`: Record a suggested change. This does not change the invoice. kind add\_line requires description, quantity, rateMinor, and unit. kind change\_rate requires lineId and rateMinor. kind apply\_discount requires discountKind, discountValue, and discountNote. kind move\_due\_date requires dueOn. kind adjust\_q
- `accept\_invoice\_change`: Apply one suggested invoice change after the freelancer explicitly approves that change. Pass confirmed true only then. This is the path that may add a line, change a rate, apply a discount, or move the due date. Calling it is not a substitute for the freelancer's approval.
