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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.07323 | $0.07323 |
| Opus 5.5 | $0.02929 | $0.02929 |
| Sonnet 5.5 | $0.01465 | $0.01465 |
| Haiku 4.5 | $0.00732 | $0.00732 |
Grade D, and why
onesub AGENTS.md scanned grade D with 4 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 26d 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.

A POST to an outside endpoint may be telemetry or may be exfiltration; either way the mod talks to somewhere, and you should know where.

OneSub Repository Guide
This is the canonical repository guide for coding agents. CLAUDE.md imports this file so Codex
and Claude share one set of project instructions. Keep durable project knowledge here; keep public
setup and API documentation in README.md and docs/.
How to use this guide. Read Build Model and Traps before your first edit — it is the section
that prevents silent failures. Then jump: Source Map for where code lives, Start Here by Task for
which files a given task touches, Contract Change Checklist for changes that must move several
files at once, Change Workflow and Before You Call a Task Done for what to run and report.
docs/AI-WORKFLOW.md holds copy-ready prompts; this file holds the rules.
Project Scope
OneSub is a self-hosted in-app purchase backend and client toolkit. It validates Apple StoreKit 2 and Google Play receipts, processes subscription webhooks, stores subscription and one-time purchase state, exposes entitlement/admin/metrics APIs, and provides React Native and Unity clients.
This public repository is the MIT-licensed Core source of truth. Commercial Unity Editor automation
and MCP for Unity custom tools live in the separate private onesub-unity-pro repository. Do not
copy Pro sources into this repository. See docs/UNITY-PRO.md for the compatibility boundary.
Repository Map
| Path | Role |
|---|---|
packages/shared |
@onesub/shared: canonical cross-package types, status values, error codes, and route constants |
packages/providers |
@onesub/providers: dependency-free App Store Connect and Google Play product-management wrappers |
packages/server |
@onesub/server: Express middleware/server, receipt validation, webhooks, stores, admin APIs, metrics, OpenAPI, and tracing |
packages/sdk |
@jeonghwanko/onesub-sdk: React Native provider, hook, paywall components, and HTTP client |
packages/mcp-server |
@onesub/mcp-server: stdio MCP tools for setup, product management, diagnostics, and simulation |
packages/cli |
@onesub/cli: onesub init scaffolder, server templates, and the onesub dev fully mocked server used for local and agent testing |
packages/dashboard |
Private npm workspace for the self-hosted Next.js operations dashboard; shipped as a Docker image |
packages/unity |
com.onesub.unity: public Unity 2022.3+ purchasing and server-validation Core package |
packages/unity-platform-services |
Optional Unity sharing, review, leaderboard, and authentication helpers; not part of purchasing Core |
examples |
Runnable server and Expo examples. Not npm workspaces, but inside this checkout they still resolve @onesub/server through the root node_modules symlink to packages/server — so they do exercise your local build. The version pin in their own package.json only applies to a standalone copy |
bench |
k6 status/webhook load tests, run by the scheduled bench workflow |
scripts |
Dependency-free repository checks such as validate-docs.mjs and validate-package-contents.mjs |
docs |
Architecture, security, deployment, migration, receipt-error, and Unity boundary documentation |
site |
Source of the static landing page at onesub.pryzm.gg. One self-contained index.html, no build step. Deliberately not an npm workspace. This repository does not deploy it — the page is copied into findthem/apps/web/onesub/ and shipped by that repository's CI to a shared EC2/nginx host; see site/README.md |
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.

onesub AGENTS.md is an instructions file published in the GitHub repository jeonghwanko/onesub (15 stars, last pushed 14d ago), licensed MIT. It adds 7,323 tokens to every session, about $0.0293 per session on Opus 5.5. A static security scan graded it D with 4 findings (sends data to an external url, asks for root, recursive force delete). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
