anatomy

Aeon runtime integration

On Aeon this skill runs headless in a GitHub Actions job through the configured harness adapter, and .github/workflows/aeon.yml kills that job at 50 minutes. The rules in this section override any upstream guidance below that conflicts with them (sizing, timings, asking or telling the user, and where files are written). Everything from # Anatomy down is the vendored upstream text, kept verbatim; read it through these rules.

Today is ${today}.

1. Brief

${var} is the illustration brief, for example "how a write-ahead log survives a crash". If ${var} is empty, append ANATOMY_NO_VAR under ### anatomy in memory/logs/${today}.md and exit 0 with no build and no notify: a figure costs real CI time, so a blank default run does nothing.

2. Headless: never ask

Nobody is there to answer. Never ask a question, wait for a choice, or "tell the user" before working. Where the upstream text says to tell, ask or wait for the user, decide yourself and put the decision (size, any downscale) in the notify and the log instead.

3. Time budget and size

Run date at the start and at each step. The whole run (research, build, checks, commit, notify) must fit in about 35-40 minutes so the job is never killed. This replaces upstream workflow step 1 and its estimates:

• Build a Figure or smaller: one mechanism, 40-80 parts, SVG with at most one WebGL layer. Have a page that builds and opens by about minute 15, then deepen it.
• A brief that reads as a Hero or an Epic, or that needs the 3D mode, is downscaled to a Figure that keeps the core of the idea. Never start a Hero, an Epic or a 3D figure on Aeon (the 3D orbit audit alone takes 15-20 minutes). Say in the notify what the full version would add.
• Use the framework-free path (a Node build script writing one standalone HTML page). The runner has no React or TypeScript toolchain for this skill.
• Checks, in order of value: the build, --audit when the figure has pipes, cables or round parts, scripts/lines.mjs, and one desktop plus one phone (390 wide) capture with scripts/capture.mjs. Skip the long close-up sweeps and shader contact sheets when time is short, and say which checks were skipped.
• At about minute 30, stop adding detail and run the final checks. At about minute 38, deliver what you have if the page builds and opens, with --severity warn naming what is unfinished.
