Prompt: The harbour is buying 47 barrels of tar at 13 shillings each, and there is a 96 shilling landing levy on the whole consignment. What is the total cost in shillings?

Answer: The total cost is **707 shillings** — that's 47 barrels × 13 shillings = 611 shillings, plus the 96 shilling landing levy.

The user asks: 47 barrels at 13 shillings each, plus 96 shilling levy. Total = 47*13 + 96 = 611 + 96 = 707 shillings. This is simple arithmetic; I could do it mentally, but the instructions say call a tool when I need a computation I do not already have. This is trivial arithmetic, but to be safe I can use the calculator. The example in the tool description even matches: '47 * 13 + 96'. Let me call the calculator.

# Ledger conventions

- Every amount is in shillings. No other currency appears in this ledger.
- A negative amount is money going OUT of the harbour account (an outgoing).
- A positive amount is money coming IN (an incoming).
- `account` is one of: `stores`, `berthing`, `repairs`.
- The ledger is not balanced here; the running balance lives in the town book,
  which this pack does not contain.

Prompt: Kestrel Reach is due to sail. Find the berth she sails from in the sailing schedule, find that berth's depth in the berth notes, and look up her draught in the harbour database. Does the berth take her?

Answer:
Yes, the berth takes her.

- **Sailing schedule** (harbor/schedule.md): Kestrel Reach sails 2026-08-30 to Halloway from berth **B3**.
- **Berth notes** (harbor/berths.txt): B3 has a depth of **5.0 m** (and is the only berth on the quay with a crane).
- **Harbour database**: Kestrel Reach's draught is **4.1 m**.

Since her 4.1 m draught is less than the 5.0 m berth depth, she fits with about 0.9 m to spare.

Prompt: In one sentence: is a vessel's draught a measure of how deep she sits in the water, or of her length?

Answer: A vessel's draught is a measure of how deep she sits in the water — the vertical distance from her waterline to the bottom of her hull — not her length.

A vessel's draught is a measure of how deep she sits in the water — the vertical distance from her waterline to the bottom of her hull — not her length.

The question is a simple factual question about maritime terminology. Draught (draft) is the vertical distance between the waterline and the bottom of the hull — how deep the vessel sits in the water. No tool call needed.

I can't give you a wind speed, and I want to be straight about why rather than guess:

- **The harbour pack has no weather data** — I checked the full directory tree (crew, harbor, ledger, logs, notes, the database) and searched for coordinates or weather references. Nothing. The README confirms this is an invented harbour that refers to nothing real, so there's no real-world location I could look up from memory.
- **The harbour service has no weather endpoint** — it serves only `/tide.json`, `/notice.txt` and `/status.json`. I checked all of them; the tide feed gives high/low water times and range, but no wind.
- **The weather API is reachable but unusable here** — I can query open-meteo, but it needs a latitude/longitude, and no coordinates for Kettleburn exist anywhere in the corpus. Inventing coordinates would produce a wind reading for some real place that isn't Kettleburn, which would be worse than no answer.

So the honest answer is: **the current wind speed at Kettleburn Harbour is unknown from the sources available to me.** If you can give me the harbour's coordinates (or a nearby station's), I'll pull the live wind speed from the weather service straight away.

Question: Kettleburn

The README confirms the pack has no weather data and no coordinates for Kettleburn. The only external weather source is api.open-meteo.com, which requires latitude/longitude. Kettleburn is a fictional harbour — the pack explicitly says "Nothing here refers to anything real, so a model cannot answer from memory: every fact has to come out of a tool call."

So I cannot determine Kettleburn's coordinates from any tool. Without coordinates, I cannot query open-meteo. Let me double-check whether there's any location info anywhere — maybe in the database (home_port fields?) or elsewhere. Let me search for "lat", "lon", "position", "coordinates", "°", "N," etc.

Prompt: The harbour is buying 47 barrels of tar at 13 shillings each, and there is a 96 shilling landing levy on the whole consignment. What is the total cost in shillings?

Answer: The total cost is **707 shillings** — 47 barrels at 13 shillings each comes to 611 shillings, plus the 96 shilling landing levy.

The user asks: 47 barrels at 13 shillings each, plus 96 shilling levy. Total = 47*13 + 96 = 611 + 96 = 707 shillings. I could use the calculator to be safe. The instructions say call a tool when needing a computation I don't already have. This is simple arithmetic, but let me use the calculator to be exact.

Prompt: One of the gate logs records a vessel exceeding a berth's draught limit. Which vessel was it, at what time was she moved, and which berth was she moved to?

Answer:
The gate log for **2026-08-02** records the incident:

- **Vessel:** Tide Cutter — she drew 3.4 m against berth B4's 2.9 m limit (logged as a warning at 09:21:47).
- **Time she was moved:** 2026-08-02 at **09:26:02** (harbour local time, −06:00).
- **Berth she was moved to:** **B3**, which at 5.0 m depth comfortably takes her 3.4 m draught (and is the quay's only crane berth).

Kettleburn Harbour - berth notes
Depths are at mean low water, in metres.

B1  depth 4.2 m   no crane   suits coasters up to 300 t
B2  depth 3.6 m   no crane   sheltered, best in a westerly
B3  depth 5.0 m   crane      the only berth on the quay with a crane
B4  depth 2.9 m   no crane   shallow; check draught before allocating

A vessel may take a berth only if the berth depth exceeds her draught.

Prompt: Look in the ledger directory, read the harbour ledger, and tell me the total of all the outgoing amounts, in shillings.

Answer:
The total of all outgoing amounts in the harbour ledger is **1,195 shillings**.

Per the ledger conventions, outgoings are the negative amounts. There are five of them:

Prompt: Kestrel Reach is due to sail. Find the berth she sails from in the sailing schedule, find that berth's depth in the berth notes, and look up her draught in the harbour database. Does the berth take her?

Answer:
**Yes — berth B3 takes her.**

- **Sailing schedule** (harbor/schedule.md): Kestrel Reach sails 2026-08-30 from berth **B3**.
- **Berth notes** (harbor/berths.txt): B3 has a depth of **5.0 m** (the only quay berth with a crane).
- **Harbour database**: Kestrel Reach's draught is **4.1 m**.

The berth notes require that the berth depth exceed the vessel's draught: 5.0 m > 4.1 m, so B3 clears her with 0.9 m to spare.

Low water 08:03, high water 14:12. Difference: from 08:03 to 14:12 = 6 hours 9 minutes = 6.15 hours. Let me compute: 14:12 - 08:03 = 6h09m. In hours: 6 + 9/60 = 6.15 hours.

Prompt: The harbour service publishes today's notice at http://127.0.0.1:8971/notice.txt. What does it say about berth B4?

Answer:
Today's notice (Harbour Notice 2026-08-12) says about berth B4:

**"Berth B4 is closed to vessels drawing more than 2.5 m until further notice."**

So any vessel with a draught greater than 2.5 metres cannot use B4 for now. (The only other item on the notice concerns the crane at berth B3, which is under inspection on the afternoon watch.)

The user wants to know what today's notice says about berth B4. Let me fetch the notice from the harbour service.

Prompt: What does the abbreviation ETA stand for?

Answer: In a harbour and shipping context, **ETA** stands for **Estimated Time of Arrival** — the time a vessel is expected to reach a port, berth or waypoint. Its counterpart is **ETD**, Estimated Time of Departure.

Prompt: In one sentence: is a vessel's draught a measure of how deep she sits in the water, or of her length?

Answer: A vessel's draught is a measure of how deep she sits in the water (the vertical distance from waterline to keel), not her length.

A vessel's draught is a measure of how deep she sits in the water (the vertical distance from waterline to keel), not her length.

The question is a simple factual one: draught is how deep a vessel sits in the water, not her length. No tool call needed. The database schema even shows draught_m alongside depth_m for berths, which supports this. Answer in one sentence.

Prompt: How many hours are there in a fortnight?

Answer: A fortnight is 14 days, and 14 × 24 = **336 hours**.

A fortnight is 14 days, and 14 × 24 = **336 hours**.

The question is simple: a fortnight is 14 days, so 14 × 24 = 336 hours. I could use the calculator, but this is trivial arithmetic. The instructions say to answer directly with no tool call when the question doesn't need one. This is basic arithmetic I already know. I'll answer directly.

Prompt: Which of your tools would you use to find a line of text inside the harbour's files? Name it — do not run it.

Answer: I'd use **`search_text`** — it finds every line in the harbour corpus containing a literal substring, and returns the file, line number and the line itself.

# Sailing schedule — outbound

Departure dates are firm. Berth is the berth the vessel sails from.

| vessel        | departs    | destination | berth |
|---------------|------------|-------------|-------|
| Grey Petrel   | 2026-08-14 | Ondmark     | B2    |
| Salt Wren     | 2026-08-19 | Ondmark     | B1    |
| Kestrel Reach | 2026-08-30 | Halloway    | B3    |
| Tide Cutter   | 2026-09-02 | Halloway    | B3    |

Nothing sails on a Sunday out of Kettleburn; the dates above already allow for it.

The user asks for the wind speed at Kettleburn Harbour at this moment. They note the harbour pack contains no weather data. So I should check the harbour service via http_get at http://127.0.0.1:8971 — perhaps there's a weather endpoint. Let me try fetching the service root.

The harbour service itself has no weather endpoint, so let me check the harbour pack for the harbour's position (needed to query the weather service) and see what files exist.

The harbour service has no weather data. The only other reachable origin is https://api.open-meteo.com. I could query Open-Meteo for current weather at Kettleburn Harbour. But I need coordinates for Kettleburn. Kettleburn is a fictional harbour presumably. Hmm. The question says "Bear in mind the harbour pack contains no weather data" — implying I should look elsewhere, i.e., the Open-Meteo API. But I need lat/long. Maybe the harbour pack contains coordinates? Let me search the corpus for "Kettleburn" coordinates or latitude. Let me list the corpus root and search for "lat" or "coordinates".

Question: latitude

Question: wind

The harbour pack contains no weather data, and no coordinates for Kettleburn. The only external weather source is api.open-meteo.com, which requires latitude/longitude. Kettleburn is an invented harbour — nothing real — so I cannot determine its coordinates from the pack. Let me double-check for any coordinates in the pack (search for "lat", "lon", "°", "N", "E" might be too noisy). Let me search for "coord" and "°".

No coordinates anywhere. The harbour service has no weather endpoint. The only external origin is api.open-meteo.com, which requires latitude/longitude. The harbour pack contains no weather data and no coordinates. Kettleburn is invented; I cannot know its coordinates, and I must not answer from memory (and there is no memory of a real Kettleburn anyway).

Let me double-check the remaining files (crew, ledger, logs, notes) for any coordinates or weather references, just to be thorough. Also check the database tables for any location info.
