plan.next

The lowest-wave READY issue of the active milestone, highest priority first, then id. The active milestone can have nothing ready while another one does — one waiting on its own acceptance evidence, for instance — so the search widens to the whole plan rather than answering `none` and sending a worker away from work that is genuinely executable. This is what an agent asks before it starts.

Schemas

The canonical input and output, from the Rust types; the MCP tool schema and the OpenAPI parameters and responses are derived from these.

input · PlanMilestoneFilter

Which part of the plan to answer about.

property	type	required	description
milestone	string \| null	no	Restrict the answer to one milestone. Default: the whole plan, and for `next` the active milestone with the rest of the plan as the fallback.

output · PlanNextIssue

The one issue a worker should take now.

property	type	required	description
active_milestone	string	yes	The milestone the search started in.
issue	one of 2	no	The issue, when the plan has one that is executable.
reason	string \| null	no	Why there is none, when there is none: what to run to see what is in the way.
