oly-apps

A way to publish a web app or API as an interactive page served by the Oly daemon, a local service that hosts these apps.

In plain words
What is it for?
Use it to create simple HTML pages, single-page apps, or proxied services with optional metadata and shared assets.
Why use it?
It provides a defined app folder and route so rich output can be opened in a browser.

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

oly-apps 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 3d 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

Overview

Publish rich output as a web app served by the oly daemon. Each app lives in its own folder under <OLY-ROOT>/wwwroot/apps/ and is reachable at:

http://127.0.0.1:<OLY-PORT>/apps/<app-name>/

Run oly daemon status to discover <OLY-PORT> and <OLY-ROOT>.

Quick start

Simple HTML app

Drop an index.html (plus any assets) into a new folder:

<OLY-ROOT>/wwwroot/apps/<app-name>/index.html

No manifest needed — oly discovers index.html automatically.

SPA or proxied service

Create oly.app.json in the app folder:

{
  "title": "My App",
  "entry": "index.html",
  "redirect_files": ["../shared-assets"]
}

Set the base href to ./ (or /apps/<app-name>/) so relative asset paths resolve correctly when served from the discovered route.

Manifest schema (oly.app.json)

Field Type Description
title string? Display name.
description string? Short description.
icon_href string? Icon URL or relative path.
app_type string? App type hint.
redirect_files string[] Extra asset directories outside the app folder. Oly checks the app folder first, then each redirect directory in order; 404 if not found.
entry string Required. URL, path, or HTML file to serve as the entry point.

Rules

  • Use relative asset paths or the /apps/<app-name>/ base — absolute paths will break.
  • One folder per app, one index.html or one oly.app.json per folder.
  • Use redirect_files to share static assets across apps without copying.
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.

oly-apps is a skill published in the GitHub repository slaveOftime/open-relay (93 stars, last pushed 7d ago), licensed MIT. It adds 21 tokens to every session and 469 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.

s-continue

Cheaper and faster than /compact. Restores previous session context from Claude Code AND Codex transcripts by reading them directly — no LLM calls, no token cost. Also auto-loads a handoff written by /s-compact, if one exists. Triggers on "s-continue", "restore context", "what was I doing", "pick up where I left off"…
