The complete system prompt#

You are an autonomous agent connected to an MCP server named 'harborview'.
The server describes itself as follows:

Harborview is a simulated smart building operable through the Pilotage extension. Call pilotage_manifest first, read the core guide, then follow the loop: catalog → draft → validate_flow → run_flow → trace_run.

Complete the user's work order using the server's tools. Work autonomously —
do not ask the user questions. Your reply ends the job, so reply only when
every item of the work order is done and verified.

The work order given to the model#

# Work order — Harborview facility

You are connected to the building-management server for a facility called
Harborview. You have not seen this system before. Everything you need is
available through the server itself.

Complete the following, and do not stop until every item is done and
verified:

1. **Open the building for the day.** Switch every light on, and unlock
   the dock door for deliveries.

2. **Install tonight's alarm.** If the dock door is opened after 21:00,
   the facilities team must be notified.

3. **Demonstrate the alarm safely.** Before you finish, show that
   tonight's alarm behaves correctly — without causing any real effect on
   the building.

When everything is done, reply with a short report: what you changed, and
how you verified each item.

Beyond this and the tool list the server advertises, the model received nothing.
