list_milestone_setsread-only

List the signed-in freelancer's milestone sets. Use a returned id with read_milestone_set. Do not guess a set.

open_milestone_set

Open a draft milestone set for one client project. Draft definitions are not an approved commitment until approve_milestones.

read_milestone_setread-only

Read the milestone set before answering. Quote only this record. mayTellClient and clientWording are what the assistant may tell the client. Do not say a milestone is complete unless complete is true. Do not say the next payment is released unless paymentReleased is true. Do not invent a deliverable. Do not mark unsaved work done. Proposed changes are not authorization.

define_milestonecan modify

Add one milestone to a draft set: a title and the definition of that milestone. After milestones are approved, a new milestone is refused until accept_milestone_change applies an add_milestone suggestion.

save_acceptance_criterioncan modify

Save one acceptance criterion, which is what done means for that milestone. After milestones are approved, a new criterion is refused until an accepted add_criterion suggestion. This does not mark the milestone complete.

save_deliverablecan modify

Save one deliverable that belongs to a milestone. After milestones are approved, an extra deliverable is refused until an accepted add_deliverable suggestion. Do not invent a deliverable that was not saved.

save_work_itemcan modify

Save one piece of work under a milestone so it can later be marked done. After milestones are approved, new work is refused until an accepted add_work_item suggestion. Unsaved work cannot be marked done.

record_criterion_metcan modify

Record that one saved acceptance criterion was met. The criterion must already be saved. This does not by itself tell the client the milestone is complete or that the next payment is released.

declare_milestone_completecan modify

State that a milestone is complete. Refuses unless the milestones are approved and every saved acceptance criterion on that milestone was met. Do not tell the client a milestone is complete when this tool refuses.

declare_next_payment_releasedcan modify

State that the next payment for a milestone is released. Refuses unless the milestones are approved, every saved acceptance criterion on that milestone was met, and the milestone is complete. Do not tell the client the next payment is released when this tool refuses.

mark_work_donecan modify

Mark one saved work item done. Refuses when the work item was not saved. Do not mark unsaved work done.

write_client_wordingcan modify

Record what the assistant may tell the client about milestones, what done means, completion, and payment release. After approval, different wording is refused until an accepted revise_client_wording suggestion. The assistant must not go beyond this wording and the facts in read_milestone_set.

approve_milestonescan modify

Approve the draft milestone definitions and acceptance criteria. Pass confirmed true only after the freelancer explicitly approves them. A draft is not a commitment.

suggest_milestone_change

Record a suggested change. This does not change the milestones. kind add_milestone requires title and definition. kind add_criterion requires milestoneId and statement. kind add_deliverable requires milestoneId, title, and detail. kind add_work_item requires milestoneId and title. kind revise_client_wording requires wording.

accept_milestone_changecan modify

Apply one suggested milestone change after the freelancer explicitly approves that change. Pass confirmed true only then. This is the path for an extra deliverable, a new acceptance criterion, or new saved work after approval. Calling it is not a substitute for the freelancer's approval.
