list_workspacesGet all workspaces the authenticated user is a member of.
list_projectsList all projects in a workspace (excluding archived).
create_projectCreate a new project in a workspace. Returns the created project. Subject to plan-based project count limits.
delete_projectPermanently delete a project. All tasks, milestones, and dependencies inside the project are also removed. This cannot be undone.
list_tasksList tasks in a project. Supports optional filtering by name (search), status, and assignee.
get_taskGet detailed information about a single task, including assignees and dependencies.
list_milestonesList milestones in a project (key dates such as launch or review gates).
create_milestoneAdd a milestone (key date) to a project.
create_taskCreate a new task in a project. Dates must be in YYYY-MM-DD format. End date is exclusive (a 1-day task has end = start + 1 day).
update_taskUpdate fields of an existing task. Only provided fields will be modified.
set_task_progressUpdate the progress percentage of a task (0-100). Status is auto-derived: 0=not_started, 1-99=in_progress, 100=done.
add_dependencyAdd a finish-to-start dependency between two tasks in the same project.
delete_taskDelete a task. Child tasks and dependencies are removed as well.
get_critical_pathCalculate the critical path of a project on the Ganty side and return it as data (don't ask the model to reason over raw task lists). Uses forward/backward CPM with progress-aware remaining duration. Returns critical_path tasks in order, per-task earliest/latest start/finish + slack, project_end_date, and total_duration_days. v1 limitations: Finish-to-Start dependencies only (Ganty has no other ty
reschedule_and_propagateCompute the downstream impact of shifting a single task. Default is dry_run (no DB writes); set mode='commit' to actually persist the changes. Cascades forward only (no pull): successors are pushed only if their predecessor's new end + lag would violate their current start. Tasks with progress=100 are treated as pinned; pass pinned_task_ids for additional pins. When a pin would be violated, the ch
