Developer Tools

Vehicle routing (VRP, TSP, PDP) with cuOpt — Python API only. Use when the user is building or solving routing in Python.

Install

The skill file stays in the publisher's repository.

Paste the copied command in a terminal. It installs this SKILL.md into that agent.

npx skills add NVIDIA/skills --skill cuopt-routing-api-python -a cursor -y

How do I install cuopt-routing-api-python?: Download skills/cuopt-routing-api-python/SKILL.md from the publisher, or copy the path and open the repository. PlugMCP lists the skill and does not host the file.
Where does cuopt-routing-api-python live?: The publisher keeps it at https://github.com/NVIDIA/skills.
Which agents can use cuopt-routing-api-python?: Claude, Cursor, and Codex can read a SKILL.md you add from the publisher's repository.

This skill is Python only. Routing has no C API in cuOpt.

Ask these if not already clear:

Problem type — TSP, VRP, or PDP?
Locations — How many? Depot(s)? Cost or distance between pairs (matrix or derived)?
Orders / tasks — Which locations must be visited? Demand or service per stop?

Problem	Fix
Empty solution	Widen time windows or check travel times
Infeasible orders	Increase fleet or capacity
Status != 0 with time windows	Add `add_transit_time_matrix()`
Wrong cost	Check cost_matrix is symmetric
`compute_waypoint_sequence` alters route_df	It replaces the `location` column with waypoint ids in place — pass `route_df.copy()` if you still need cost-matrix indices (e.g. when iterating per truck)
