Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00126 | $0.00570 |
| Opus 5.5 | $0.00050 | $0.00228 |
| Sonnet 5.5 | $0.00025 | $0.00114 |
| Haiku 4.5 | $0.00013 | $0.00057 |
Grade A, and why
build-with-opengeni 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 17d 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
Build with Opengeni
The user's product keeps its own users and UI. Opengeni (Opengeni Cloud at
https://app.opengeni.ai, or self-hosted) runs the agent sessions and tools.
The browser talks only to the product's server, which holds the organization
API key.
Follow the complete guide beside this file:
opengeni-client/SKILL.md. Without it, read
https://docs.opengeni.ai/llms.txt and
https://github.com/Cloudgeni-ai/opengeni/tree/main/.agents/skills/opengeni-client.
Opengeni MCP tools
When the opengeni MCP tools are available (this plugin connects them), use
them to inspect and act on the user's Opengeni organization while you build:
find an action with opengeni_actions_search, read it with
opengeni_action_describe, and run it with opengeni_action_call. The first
use opens a browser sign-in where the user chooses what the agent may access.
The product's own code still uses its server-side API key.
Quick local demo app
If the user asks for a small, local, or demo web app with an Opengeni chat
(rather than adding Opengeni to an existing product), follow
local-demo-app.md exactly. It is a tested recipe: a Vite
and React page with OpenGeniChat and one Node server holding the API key.
Credentials
- The user creates an organization API key in Opengeni under Organization
settings > Developer and stores it in the product's server-only env as
OPENGENI_API_KEY. Never ask them to paste it into chat, and never commit, log, or ship it to a browser or mobile app. - Self-hosted deployments also set
OPENGENI_API_BASE_URL. - Do not deploy, publish, or change production without the user's permission.

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.

build-with-opengeni is a skill published in the GitHub repository Cloudgeni-ai/opengeni (205 stars, last pushed today), licensed Apache-2.0. It adds 126 tokens to every session and 570 once invoked, about $0.0005 per session on Opus 5.5. 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 2026-10-02.
