aholo-viewer: Skill for Codex

.codex/skills/aholo-site/SKILL.md

aholo-site is a skill for Codex from manycoretech/aholo-viewer. It costs 69 tokens per session (459 once invoked), scanned A, original, MIT.

A development guide for the Astro website and Playground of Aholo Viewer, a browser-based 3D viewing package. It covers pages, layouts, interface components, rendering in the browser, URL state, and scoped styles.

In plain words
What is it for?
Use it when changing Aholo Viewer routes, website layouts, examples-page chrome, Playground controls, Monaco code editing, browser rendering, camera controls, inspector panels, presets, or website styles.
Why use it?
It clarifies which website files own each feature and preserves agreements such as Playground URL parameters and renderer type hints. This helps prevent website changes from breaking the interactive viewer or crossing into renderer code.

Skill for Codex

Written for Codex: agents/openai.yaml present.

This is manycoretech/aholo-viewer's own configuration. It tells Codex how to work on aholo-viewer itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything aholo-viewer configures →

About the project

Aholo Viewer is a renderer for 3D Gaussian Splatting scenes and meshes, using chunked streaming and level-of-detail handling for large 3D data. It is packaged as an npm workspace with documentation and includes skills that help coding agents integrate the renderer.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

aholo-site scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Aholo Site

Own the website shell and Playground integration. Do not own renderer source or example content pairs.

Owns

  • Astro routes, layouts, flat feature components, utilities, i18n, and site content under website/.
  • Examples page chrome and preview layout, not website/src/content/examples/*.json or *.ts.
  • Client render runtime under website/src/client/, camera/control integration, inspector, presets, and URL state.
  • Playground shell in website/src/components/PlaygroundShell.astro and browser entry in website/src/client/playground.ts.
  • Scoped styles: theme.css, global.css, site.css, home.css, examples.css, docs.css, playground.css.

Boundaries

  • Keep Monaco route-local through website/src/components/PlaygroundShell.astro; keep Playground browser entry in website/src/client/playground.ts.
  • Preserve Playground URL params: example and code.
  • Keep render runtime implementation in website/src/client/render-runtime.ts and runner contract in website/src/client/render-runtime.d.ts.
  • Keep renderer type hints sourced from packages/renderer/dist/index.d.ts.
  • Keep website/src/content.config.ts focused on Astro collections; manual pages are loaded through website/src/utils/manual.ts.
  • Keep feature selectors out of global.css.
  • Do not modify renderer public exports.
  • Do not hand-edit website/.generated/api/.
  • Use aholo-examples for example JSON/TS source pairs.

Design

  • Keep the site simple, refined, spacious, and tool-like.
  • Keep homepage first-screen interactive renderer true fullscreen and resize the renderer after entering or exiting.

Validate

pnpm.cmd check:website

Use pnpm.cmd check when renderer declarations or package output are involved.

Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
