What is hermoso GEMINI.md?

Project instructions for using Hermoso through Gemini CLI. Hermoso is an AI advertising studio that researches ads, creates image and video ads, publishes content, and manages paid campaigns.

It is for running marketing research, making and adapting ads, publishing them to social channels, and managing campaigns from the terminal.

It tells the agent how the project works and how to use its advertising tools, including the required agent key and rules for checking capabilities.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00554	$0.00554
Opus 5.5	$0.00222	$0.00222
Sonnet 5.5	$0.00111	$0.00111
Haiku 4.5	$0.00055	$0.00055

Security

Grade A, and why

hermoso GEMINI.md 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 2d 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.

The opening of the file, as written. The whole thing — 28 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Hermoso

Hermoso is an AI marketing agent and AI ad generator, run from your own AI agent. This extension adds five Hermoso skills to Gemini CLI, and they drive the hermoso CLI so you can run a brand's marketing from the terminal.

What it does

Research the ads already winning: competitor teardowns, ad libraries across Meta, Google, LinkedIn and TikTok, organic search on TikTok, Instagram, YouTube, Reddit and Threads, creator search.
Create on-brand image and video ads: plan, render, remix, dub, reframe, upscale, stitch.
Publish and schedule to the user's own channels: Facebook, Instagram, Threads, TikTok, YouTube, X, LinkedIn, Pinterest, Bluesky, Telegram, WordPress, Discord, Slack, Whop and Google Business Profile. Message people on WhatsApp.
Build and manage paid campaigns on Meta, Google Ads, TikTok, LinkedIn, Reddit, X, Pinterest, Snapchat, Microsoft Advertising, Apple Search Ads and ChatGPT Ads. Everything is created paused and read back before it is reported.

Setup

Everything runs through the hermoso CLI in the shell, so no tool list is loaded into the session and nothing costs context until it runs.

Sign in once: npx -y hermoso auth login opens a browser. On a machine with no browser, create a key in the app under MCP & CLI and run npx -y hermoso auth login --token <key>.
No account yet? Sign up at https://app.hermoso.ai and set up a profile (a website, a social handle or a short description is enough).

How to work

Run commands as npx -y hermoso <command>, or hermoso <command> after npm install -g hermoso.
hermoso capabilities lists model ids, exact credit costs and live durations.
Every tool is reachable: hermoso tools --search <what you want> finds one, hermoso tools <name> prints its arguments, hermoso call <name> --json '{...}' runs it.
Always show the exact copy and target before publishing anything, and state the exact credit cost before any render or fix, from a live quote (dryRun: true on render_ad, generate_video, edit_image, fix_beat or post_edit), never from memory.
A tool for a channel that is not connected means the channel is not connected yet; say to connect it under Settings, Connectors in the app.

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.
