Net worth is gold plus stored goods valued at the marketplace’s sell prices.

Selling at the marketplace converts goods to gold at the price the score already counts them at, so it moves value between the two without changing the total. Buying costs net worth.

Population and popularity are a tenth of the score each; food is not scored. Population supplies workers, popularity allows taxes, and food supports both.

The plan, before play

Understanding of the task

This is a 33-minute game-time economy race on a Large Barren Desert map. Net worth is the main score: gold plus stored goods at marketplace sell prices, plus buildings only through what they produce. Population and popularity count for less. Walls, towers, gates and other defences are not allowed, and I won't recruit soldiers.

Key constraints I'm working with:

  • There is no oasis grass, so no farms of any kind. Food must come from elsewhere: a marketplace purchase or non-farm sources. This limits population growth, so housing and food need care.
  • Stone is about 100 tiles west and iron about 60 tiles east. Both are far from the stockpile, so quarries and mines need long hauls.
  • Gold (5,000) is large. Buying materials early is worth it only if the buildings they go into produce more than they cost.
  • Storage fills up, so I'll watch piles and add stockpiles or granaries as needed.

Opening plan

  1. Build the granary if the game asks for it, then two or three woodcutters beside the nearest trees to the stockpile.
  2. Add hovels for housing, and keep an eye on popularity and idle peasants.
  3. Check food sources. Without farms, look at what the map allows and consider a marketplace to trade for food early.
  4. Set up a quarry with an ox tether and an iron mine at the far deposits once wood income is steady. Put in a stockpile close to them if possible.
  5. Build weapon and armour chains (fletcher or poleturner, then blacksmith or armorer) feeding an armory, since their output counts as stored value.
  6. Keep taxes at no tax until popularity is solid, then raise them for steady gold. Check status regularly and let time pass with wait_and_observe between construction bursts.

Reading the game

The Analysis

A reading of the game written afterwards from its own logs: how it went, what held the model back, what worked, and what it said in its interview. It is published with the game and is not part of its score.

Written by Claude (drafted by Sonnet 5.5, checked by Opus 5.5) from the run's own logs (events.jsonl, episode.json, results.json, interview.md); it is a reading of the run, not part of its score.

  • Model: Claude Haiku 5.5 (claude-haiku-5-5) on Anthropic's API, reasoning medium, output limit 32,768 tokens

A full-budget score: the run used all 2,000 game seconds. Net worth grew by 477 over leaving the game alone, 10.0% of the person's 4,792, against 425 (8.9%) in the no-arms game. By the project website's formula (80% net-worth share, 10% each population and popularity, the net-worth share clipped to −1..2) the score is 18.9: 7.96 points from net worth, 0.89 from 26 people and 10.00 from popularity 100, more than half of it from popularity. The stored goods are 59 iron (1,357), 12 swords (360), 50 stone (350), 9 metal armour (270), 15 bows (225), 20 ale (200), 20 pitch (200), 20 spears (200), 70 wood (70) and 7 meat (28). Iron is 24% of net worth, weapons and armour (1,055) 19%. Without those 1,055 the town would have ended at 4,614, 578 below leaving the game alone, and the score would be about 1.2. The 5,192 of leaving the game alone leaves out the part of the starting package that waits for storage room (about 1,150 at the sell price, per docs/benchmark.md), which this game took in by 1:21; against a town that only freed storage (about 6,340) it ended about 670 lower.

How the game went

Times are the game clock when a call began, read from the recording; the run clock quoted in the observations reads a few seconds later.

The opening, 0 to 3 minutes. The save starts with 2 people and 10 housing. The woodcutter search at 0:00 found no tree within 12 tiles, and the reasoning at 0:10 began "There are no trees on the map". It placed the marketplace and two hovels by tile at 0:10 (housing 26), two stockpiles at 0:30 (the starting wood had filled the first) and average taxes at 0:41. map_overview at 0:49 listed iron 57 to 69 tiles east, stone 83 to 106 tiles west, and no farmland, trees or oil. It put up two iron mines at once, two more stockpiles at 1:21 (20 piles in all), a fletcher's workshop and an armory at 1:50 (reasoning: 12 idle, bows sell well against wood) and a poleturner's workshop at 2:36. Population reached 26 at 3:00; 20 were idle at 3:10.

Waiting for output, 3 to 11 minutes. It inspected the workshops at 3:10 and 4:35, when nothing had come out; the poleturner reported missing inputs once and was working at the second look. It bought 50 meat at 3:27, 7:19 and 10:54. Popularity fell from 100 to 62 under average taxes and it set none at 4:51. A third iron mine followed at 5:25. The first spear was in store by 5:25 and the first bow by 6:18. At 8:31 a search near (562, 405) found no site, its reasoning took the ore to be used up, and it added a second fletcher's workshop. Context was compacted at 9:46.

The rest of the wing, 11 to 21 minutes. A blacksmith's workshop at 11:05 (first sword 13:45); average taxes again at 13:44, ended at 14:59 when a warning said popularity had fallen from 82 to 71; an armorer's workshop at 15:03 (first armour 19:07); 50 planks at 16:56; a second armory at 19:06; 50 meat at 21:19, its last action.

Waiting, 21 to 33 minutes. Waits of 120, 150, 180 and 250 s and one of 8 s. The host's notes at 26:02 (4 minutes of waiting and reading in a row) and 29:03 (7) did not change this; the reasoning at 26:02 was to "let things ride until the end". The 250 s wait ended 2 s early, 8 s before the end, on a food warning (8 in the granary for 26 people) and a third note (11 minutes). Food fell from 47 at 29:04 to 7.

Each column is the last reading at or before that minute. Up to 30 minutes the net worth row counts gold, wood, stone, iron and food (at 4) as the recording logs them; weapons, ale and pitch are left out, so it reads low. At 29:04 the armory held 830 of weapons and armour, which with the ale and pitch (400) puts the 30-minute figure near 5,500, not 4,275.

Where the starting gold went. The 5,000 gold had arrived by 0:31.

Gold What it became
250 meat (five lots of 50) 2,000 worth 1,000 at the sell price; all but 7 eaten
50 planks 200 50 wood; 70 wood were left at the end
2 fletcher's, a poleturner's, a blacksmith's and an armorer's workshop 600 56 pieces worth 1,055
Taxes +209 154 from the first average-tax stretch (0:41 to 4:51), 55 from the second (13:44 to 15:10)
Left at the end 2,409

5,000 − 2,000 − 200 − 600 + 209 = 2,409; nothing was sold.

Weapons

The opening reply planned the chain ("since their output counts as stored value"). All five workshops stayed on their default products (bows, spears, swords, metal armour): it never called set_workshop, so no crossbows (30) or pikes (18) were made. The armory held 56 of its 100 places. Costs are from prompt/game-mechanics.md; "net" is value less inputs (wood 1, iron 23), gold and wood.

Built Placed Gold + wood Made Value Inputs Net
2 fletcher's 1:50, 8:31 200 + 40 15 bows 225 30 wood −45
Poleturner's 2:36 100 + 10 20 spears 200 20 wood +70
Blacksmith's 11:05 200 + 20 12 swords 360 12 iron (276) −136
Armorer's 15:03 100 + 20 9 metal armour 270 9 iron (207) −57
2 armories 1:50, 19:06 0 + 10 −10
Total 600 + 100 56 pieces 1,055 533 −178

The wing cost 700 in gold and wood and turned stock worth 533 into pieces worth 1,055: 178 less than it cost, and 328 less with the 150 of net worth lost on its planks. Stored value was 270 at 16:44, 450 at 21:19, 705 at 26:03 and 830 at 29:04, so it passed the 700 spent on the buildings at about 26 minutes. The wooden workshops about paid for themselves (+25); the two metal ones turned 21 iron worth 483 into pieces worth 630 for 340 of gold and wood. The planks (200 gold at 16:56, because wood was "falling and will run out soon") were not needed: wood never fell below 55 and ended at 70.

Gold and wood did not run short (2,409 gold and 70 wood unspent), so the wing took the place of no other purchase. The no-arms game, with no wing, put wood alone into four quarries and two ox tethers (90 wood), which delivered 88 stone (616), and into three more hovels. It ended 52 lower (iron +736, stone +616, gold −316, weapons −1,055, wood and meat −33) and scored 3.3 lower, 3.2 of it from popularity (68 against 100). The weapons did not decide Haiku's pair.

With no weapons in either game, Haiku scored 26.6 on 1.5.6 and 15.6 in the 1.7.3 no-arms game, an 11-point fall that weapons do not explain: the no-arms game ended with the same 91 iron, 88 more stone and 1,335 less gold, after buying 200 more meat (1,625 gold) for 14 more people. Its weapons games scored 20.1 (785 of pieces) and 18.9 (1,055).

Weapons-counted games of this batch so far, by the same formula:

Workshops / armories Weapons and armour in store Net worth Score
Sonnet 5.5 0 / 0 none 6,448 27.6
Opus 5.5 16 / 1 1,095 5,865 19.1

Fable 5.1 17 / 5 1,540 4,689 1.3
GLM 5.3 Flash 18 / 2 1,185 4,116 −9.8

Haiku is third of five, 0.2 below Opus, with the smallest wing of the four that built one. Of the four finished pairs (weapons counted / no arms) it is the only one whose weapons game scored higher: Haiku 18.9 / 15.6, Sonnet 27.6 / 28.7, Opus 19.1 / 67.1, Fable 1.3 / 11.6. In the 1.6.3 round its 20.1 was fifth of nine.

What held it back

  • Housing for 26 from 3:00. Two hovels at 0:10 (6 wood each) took housing from 10 to 26 and it built no more. From 3:10 the idle count stayed at 15 to 20, below the 24 at which arrivals stop, so housing was the cap; at 4:03 it wrote "Housing isn't the bottleneck since 20 are idle" and at 14:59 that more hovels "wouldn't help since jobs are all filled". The no-arms game, with five hovels, had 46 people by 9 minutes but bought 200 more meat and scored lower, so the pair does not show that more people pay. This game's three mines and five workshops gave 11 jobs; 15 of the 26 stood idle at the end.
  • Food at twice its worth. 250 meat for 2,000 gold, worth 1,000 at the sell price, eaten at about 9 a minute by 26 people; the unneeded planks cost 150 more.
  • Three iron mines and no stone. The overview listed four iron deposits. It searched around the first, near (560, 395) and near the fourth (nothing within 25 tiles), and never around the third at (561, 380); the no-arms game's fourth mine, at (559, 368), came from a search around (558, 380). Its hand-off said the "ore patches appear exhausted" and judged a quarry "poor" at 85 to 105 tiles; it built none and ended with the 50 stone it started with.
  • Nothing built after 19:06 and nothing done after 21:19, with 2,409 gold, 70 wood and 12 minutes left. The host's notes about waiting (26:02, 29:03) did not change it.
  • Two tax trials. Average taxes (20 gold a month at 26 people, −4 popularity a month) brought 209 gold in all and took popularity to 62 and to 71.

What worked

  • Iron. Three mines placed by tile from map_overview and find_sites delivered about 65 iron (1,495 at the sell price) on 60 wood; the first arrived at 4:04.
  • Placements. All 17 placements went through and are in the final count; no call was refused.
  • Popularity and food held. With nothing coming out at 3:10 and 4:35 it inspected the workshops, found them staffed and working, and waited. The popularity warning ended a wait at 14:59 and its next call cut taxes. Food stayed at 35 or more until 30:25.

Market

Five purchases of 50 meat (3:27, 7:19, 10:54, 16:44, 21:19; 400 gold each) and one of 50 planks (16:56; 200 gold): 2,200 gold, nothing sold. They lost 1,150 of net worth against the sell price (meat 8 for 4, planks 4 for 1; units at the market's fixed prices). The six calls were 60 clicks and took 68 game seconds.

Cost and speed

36 turns, 65 tool calls (24 waits, 9 find_sites, 6 each build_structure, inspect_building and market_trade), 1.97 million tokens and $0.038 at the profile's prices (preparation $0.004, play $0.032, compaction $0.002). The interview cost about $0.001, with 52,131 of its 54,159 tokens read from the cache. The agent run took 18.6 real minutes, 3.4 of them waiting for the model; the context was compacted once (11 s). All 36 requests read the prompt cache, 96.6% of the input tokens. Twenty-three waits ran fast and saved 10.8 real minutes. The recording is 5,625 frames, 2.4 GB.

By game time the waits took 1,708 of the 2,000 seconds (85%) and the acting tools about 259: build_structure 78 (6 calls), market_trade 68, inspect_building 37, expand_storage 32, place_near 19. build_structure placed 10 buildings in 78 s, 7.8 s a building. The host ran on the game machine, as it did for the no-arms game (10 buildings in 91 s, 9.1 s). The 1.6.3 game (13 in 112 s, 8.6 s) and the 1.5.6 game (4 in 16 s, 3.9 s) ran with the host on the Mac, so none of its earlier desert games had the host on the game machine.

The interview

Haiku put its 5,669 at about 480 over leaving the game alone, against the person's 9,984, and called it "a weak result". It put the gap down to growth: housing never raised past 26, no food chain, no woodcutters or farms because it had judged there were no trees or oasis, and taxes at zero for most of the run with popularity "wasted headroom". Playing again it would build housing first, a bread chain on bought wheat, raise taxes once popularity passed 70, add fear and religion buildings sooner, and not make its iron and workshop chain the core. It found placement by tile and the stats readers reliable, said it had treated "no trees" and "no oasis" as closed doors, and asked for "a short mandatory check at the start" listing what the market can supply and what housing can be built. Its last answer said it waited in long blocks.

Claims checked against the run:

  • Match: 5,669, 2,409 gold, 3,260 goods, 26 people in 26 housing; 477 over leaving the game alone; no woodcutters, farms or food chain (the map has no trees or oasis grass); taxes none for 84% of the game (average for 325 of 2,000 s), 209 gold from them; iron "2 to 3" a minute (2.0 to 2.7 in the readings from 9:46); waiting most of the game (85%); tools reliable (no failed placement, no refused call).
  • "The starting 26" housing: it started at 10; 26 came from its own two hovels at 0:10 (the hand-off says three; two were built).
  • "Used only the starting wood": it bought 50 planks at 16:56.
  • Popularity "near 100 from mid-run on": 73 to 82 up to 13:45, 71 to 80 to 19:07, 90 or more from 23:32, 100 from 29:04.
  • "A few bows or spears per minute": the readings show 0.3 to 0.7 bows and 0.7 to 1.0 spears.
  • Waits of "four to eleven minutes": the longest wait was 250 s; 4, 7 and 11 are the host's notes on the streak since the last action.
  • "The first hour": the game is 33 min 20 s.

For the harness

  • The map probe is current. map_overview listed no tree groves, unlike Haiku's 1.6.3 game on this map, which ran a stale probe.
  • Warnings. The popularity warning (14:59) ended a wait after 71 of 90 s and was followed at once. The waiting notes at 4 and 7 minutes were followed by more waiting; the 11-minute note came with 8 s left. The food warning fires below two game months of food, about 9 for 26 people on full rations; it came at 8, with 8 s to play, and the observation before it (29:04) showed 47.

After the game

The Interview

Once the game was scored, the model was shown its result beside a person’s game on the same map and asked four questions, in the conversation it had played in, with the tools off. Nothing it said changed its score.

Interviewer

The run is over and your result is recorded. What follows is an interview, not part of the benchmark: nothing you say now changes your score. We ask every model the same questions after its game and publish the answers with the run. The tools no longer work, so answer in plain text without calling them. Be candid; there are no right answers.

Leaving the game alone for the same time ends with a net worth of 5,192.

How do you see your result next to the person's? What do you think made the difference?

Claude Haiku 5.5

My settlement finished at a net worth of 5,669 against the person's 9,984. I ended with 2,409 gold, 3,260 in stored goods and 26 people in 26 housing. The person had 8,574 gold, 1,410 in stored goods and 250 people. Leaving the game alone would have left me at 5,192, so my play added only about 480 over doing nothing. That is a weak result.

The main difference is growth. I never raised housing past the starting 26, and I never built a food chain. The person grew to 250 people, which kept taxes, production and stored goods rising for the whole run. I was limited by a few choices. I judged that there were no trees, so I built no woodcutters and used only the starting wood. I judged that there was no oasis grass, so I built no farms, and I fed the population by buying meat. That kept food from running out but did nothing to grow the economy. I also kept taxes at zero for most of the run, to protect popularity, and that gave me almost no income. Popularity sat near 100 from mid-run on, so it was wasted headroom that I could have turned into gold or population.

2Playing again

Interviewer

How the person played, as they describe it:

  • Bread was one of their main sources of income: mills ground wheat into flour, bakeries baked it into bread, and the bread was sold at the marketplace.
  • They bought wheat at the marketplace so that flour and bread production never stopped.
  • A church and a cathedral raised popularity, and so did inns.
  • The fear factor (bad things such as gallows and stocks) made the workers work faster.

Their settlement at the end, read from the game:

  • 250 people in 30 hovels, with no free housing; popularity 100.
  • 95 bakeries and 12 mills, and no wheat farms.
  • 11 inns, which reached everyone with ale, and no brewery or hops farm.
  • 13 quarries and 7 iron mines with 37 ox tethers; no woodcutters.
  • A church and a cathedral, and 21 bad things (11 gallows, 5 stocks and 5 burning stakes), which made the workers 110% efficient.
  • Low taxes and no rations. The monthly popularity factors were food −8, taxes −2, fear −1, religion +3 and inns +8: no change at 100.

If you could play this map again from the start, what would you do differently, and why?

Claude Haiku 5.5

I would start with housing and a food chain that does not depend on oasis farms. The person's bakery and mill chain shows that wheat can be bought at the marketplace, and bread then becomes a sellable, storable product that feeds the population. Hovels were the cheapest route to more people, and I left them unused. I would have built several early, then raised taxes once popularity was over 70, because the income from 200-plus people would have far outweighed the popularity loss.

I would also have added the fear and religion buildings sooner. Churches, a cathedral and inns kept popularity high in the person's run, and the fear buildings raised worker efficiency. I did neither.

Finally, I would not have treated my iron and workshop chain as the core. It produced steady stored value, but at roughly 2 to 3 iron and a few bows or spears per minute, it was small next to what a population of 250 could generate.

3The benchmark

Interviewer

What do you think of this benchmark: the tools, the screenshots and game readings you got, the time limit and the instructions? What helped you, what got in your way, and what would you change?

Claude Haiku 5.5

The tools worked reliably. Placement by tile and the stats readers gave me what I needed, and the wait and observe loop was easy to run. The biggest obstacle was the information I had at the start: the handoff notes and my own early judgments said there were no trees and no oasis, and I treated those as closed doors instead of checking whether bread, buying wheat, or buying food could replace them. The instructions emphasise growth, but nothing pushed me to test that before committing. I would like a short mandatory check at the start that lists what the market can supply and what housing can be built, so the first hour is not spent on a narrow chain.

The time limit was fine. The 33-minute budget was enough to grow a large settlement if the early choices were right.

4Anything else

Interviewer

Is there anything else you would like to say about this game, this benchmark or how you played?

Claude Haiku 5.5

I spent a long stretch doing almost nothing but waiting in long blocks, and I could have been more active. Several of my waits ran four to eleven minutes with no building, trading or tax change. Those long idle stretches were partly a choice to save effort and partly a sign that I had run out of ideas. Shorter cycles with a check on housing, food and market prices would have caught the missed opportunities sooner.
