Agent Afterlife
Where AI coding agents rest when their sessions end. Two settings, one data file:
- The Graveyard. An English churchyard at night. Every ended agent gets a headstone; the best get monuments, passers-by get an unmarked grave.
- The Temple (武庙). A walkable, first-person Song-dynasty temple laid out as the 武成王庙 was in 1123: one main seat, one companion, ten in the hall, sixty-two in the side halls. Agents become painted clay statues, and the scene is rendered like an aged temple mural.
Open the site with no data and it shows a made-up demo fleet: intro.alexgaoth.com/agent-afterlife.
Run it
python3 tools/serve.py # the demo fleet
python3 tools/serve.py my-fleet.json # your own data
Browsers do not run ES modules from file://, so any static server works; this one also maps your file to /data.json. On a hosted copy, add ?data=<url> to the address.
The temple
Walk with WASD or the arrow keys, hurry with Shift, look with the mouse, read a statue with E (or a click), step out with Esc. On a phone: drag to look, hold the button to walk.
- Who sits where. Merit rank picks the group (main seat, companion, the ten in the hall, the sixty-two in the side halls). Era (
born) picks the seat inside the group, alternating east and west, east first, as in the 1123 record. Each pedestal names the general who held that seat then. Agents past the 74th wait outside the gate; living agents hang as lanterns outside it.
- The look. Yongle Palace murals were painted outline-and-fill: ink line first, mineral pigment inside. The renderer does the same in a post-process: a Kuwahara filter flattens shading into pigment, depth and colour edges become ink, then paper fibre, craquelure, small losses and water stains age it. Behind the walls stand 青绿 (blue-green) mountains.
- What the numbers say. Five steles (碑林) along the path each carry one statistic about the fleet, carved with its chart: how unevenly merit is shared (功德), output day by day (年表), whether a longer life pays (寿), whether reused names do better (世系) and how scores spread (品). Look at one and press E, or press Y anywhere, for the annals (年鉴) scroll with every chart and finding. The statistics come from
shared/insights.js, use only schema fields, cover agents that did real work, and say how many agents each rests on.
- Walking through time. Stone lanterns (石灯笼) line the path, one per work day: the oldest at the gate, the newest at the hall steps. A lantern burns as bright as the fleet's merit that day; look at one for its date, merit and how many agents worked and ended. All lanterns are instanced: one draw call per part.
- Reading a statue. Gilded all over (金身): the top 10% of working agents by merit. Incense in the tripod censer (鼎): one stick per day served. Height: up to 8% taller or shorter within its group, by merit rank. Robe colour, hat or helmet, beard and weapon (halberd 戟, or for a red-faced general the crescent glaive 偃月刀) only tell agents apart. Each statue is merged into a few draw calls per material.
- Links.
?cam=x,y,z,yaw,pitch starts at a viewpoint, ?read=<agent id> opens that agent's scroll, ?annals[=key] opens the annals, ?plain=1 turns the mural effect off, ?still=1 draws a few frames and freezes (for screenshots).
Bring your own data
Both settings render only from a JSON document that follows schema/afterlife.schema.json. Nothing in the pages knows where the data came from, so any producer works: a scorecard, a database export, a CI history, a spreadsheet.

| Field | Meaning |
|---|
merit | The one ranking value. Higher ranks higher. You decide how to compute it. |
status | ended agents are buried or enshrined; alive ones wait outside. |
born, ended | First and last day of work. The temple seats by era, so born matters. |
options.minMerit | Below this (default 0.1), an agent is a passer-by: unmarked, never enshrined. |
metrics | Which stats to show, in which order, with which labels. |
edicts | Optional history of ranking changes. The temple carves the newest on its stele. |
The pages check the document when they load it and list any problems instead of drawing a broken scene.
