Add a finish-to-start dependency between two tasks in the same project.

successorId	string	required	Task that can start after predecessor finishes
lagDays	number	optional	Optional lag in days after predecessor finishes

  "type": "object",
  "properties": {
    "predecessorId": {
      "type": "string",
      "description": "Task that must finish first"

    }
  },
  "required": [

  "additionalProperties": false
}

delete_task

Delete a task. Child tasks and dependencies are removed as well.

Parameters1

taskId

string

required

Raw schema

{
  "type": "object",
  "properties": {
    "taskId": {
      "type": "string"
    }
  },
  "required": [
    "taskId"
  ],
  "additionalProperties": false
}

get_critical_path

Calculate 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 types), calendar days by default (business_days=true skips Sat/Sun but no holiday table), ignores multi-period segments, no resource calendars. Returns { error: 'cyclic_dependency', cycle } if a cycle is detected.

Parameters3

project_id	string	required	Project ID (UUID)
as_of_date	string	optional	YYYY-MM-DD. Start point for projecting remaining work. Defaults to today.
business_days	boolean	optional	If true, skip Saturday and Sunday in duration calculations. National holidays are still treated as working days (v1 has no holiday table). Defaults to false.

Raw schema

{
  "type": "object",
  "properties": {
    "project_id": {
      "type": "string",
      "description": "Project ID (UUID)"
    },
    "as_of_date": {
      "type": "string",
      "description": "YYYY-MM-DD. Start point for projecting remaining work. Defaults to today."
    },
    "business_days": {
      "type": "boolean",
      "description": "If true, skip Saturday and Sunday in duration calculations. National holidays are still treated as working days (v1 has no holiday table). Defaults to false."
    }
  },
  "required": [
    "project_id"
  ],
  "additionalProperties": false
}

reschedule_and_propagate

Compute 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 change is recorded in 'conflicts' and not propagated further. In mode='commit', if any conflicts exist nothing is written (all-or-nothing transaction). Same v1 limitations as get_critical_path: FS only, calendar days by default, no holiday table, ignores multi-period segments.

Parameters7

task_id	string	required	Task ID (UUID) to shift
shift	string	optional	Relative shift like '+3d' (push back) or '-2d' (pull earlier). Specify exactly one of shift or new_start_date.
new_start_date	string	optional	Absolute new start date as YYYY-MM-DD. Specify exactly one of shift or new_start_date.
mode	string	optional	dry_run (default): compute and return; do not modify DB. commit: write to DB in a single transaction, but only if no conflicts. Audit logged on commit.
respect_dependencies	boolean	optional	If false, only the named task moves; successors are not cascaded. Default true.
pinned_task_ids	array	optional	Additional task IDs to treat as pinned (in addition to progress=100 tasks).
business_days	boolean	optional	If true, skip Sat/Sun in duration math. Defaults to false.
