How to use the Cyber Terminal Deck agent skill
Updated · written with AI from the project's own documentation and checked against our catalogue data
Cyber Terminal Deck (skill name deck-hermes-cyber) is an agent skill that tells a compatible AI agent how to lay out a presentation in a hacker-terminal style: near-black background, faint grid and scanline effects, a shell-prompt title, and large mint-green type. It is aimed at reviewing command-line tools, agents, and developer tools, with sections for traces, diffs, and benchmarks. This guide explains what a skill is, how to install this one, how to ask for a deck, and what to check before you use it.
Cyber Terminal Decknexu-io/html-anything · Apache-2.0 Download the skill Quick start
- 1Download the ZIP. Get the deck-hermes-cyber ZIP from our page.
- 2Unzip into a skills folder. Extract the deck-hermes-cyber folder into ~/.claude/skills/ for personal use, or into the project's .claude/skills/ folder.
- 3Or upload in the Claude apps. In the Claude apps, go to Settings → Capabilities → Skills and upload the ZIP if that option is available to you.
- 4Install JetBrains Mono. Install the JetBrains Mono font on the machine where you will view the deck so the intended typeface renders.
- 5Ask for a terminal-style deck. Describe your CLI, agent, or dev tool and the sections you need, and ask for the Cyber Terminal or hacker terminal look.
- 6Review and test the output. Open the generated HTML, check contrast and text size, and test it on the display you will present on.
What an agent skill is and what this one does
An agent skill is a folder of instructions that an AI agent reads when it is relevant to a task. This skill is a styling and layout guide with an example HTML file, not a program. Its main file is SKILL.md, and the example file is example.html.
When the skill is active, the agent can turn your content into a presentation with a near-black background (#0a0c10), a 56px cyber grid, a CRT-style vignette, macOS-style window buttons, a $ prompt-style title, mint-green large type (#7ed3a4) set in JetBrains Mono, stroke-only bar charts with a blinking cursor, and amber, green, and red tags.
- Look: dark terminal theme with grid and scanline effects
- Structure: sections for traces, diffs, and benchmarks
- Output: an HTML slide deck in a 16:9 aspect hint
Install the skill from the ZIP
Download the ZIP for deck-hermes-cyber from our page. Unzip it so the deck-hermes-cyber folder (containing SKILL.md and example.html) sits inside one of the skills folders below.
For a personal setup, put it in ~/.claude/skills/. For a single project, put it in the project's .claude/skills/ folder. You can also upload the ZIP in the Claude apps under Settings → Capabilities → Skills, if your plan includes that option.
- Personal: ~/.claude/skills/deck-hermes-cyber/
- Project only: .claude/skills/deck-hermes-cyber/ inside your project
- Claude apps: Settings → Capabilities → Skills → upload the ZIP
~/.claude/skills/deck-hermes-cyber/Trigger the skill with a natural request
You do not need a special command. Describe a presentation about a CLI, agent, or dev tool and say you want the terminal or hacker look. The agent can match your request to the skill's description, which covers the dark terminal style and the review or demo use case.
Be specific about your content. Name the tool, list the sections you want (such as a trace, a diff, or a benchmark), and say how many slides you need. The skill works best when your material is clearly a technical review or demo.
- Make a 6-slide review deck about my new CLI tool in the Cyber Terminal style, with a trace slide, a diff slide, and a benchmark slide.
- Turn these release notes into a terminal-style demo deck with green and amber tags for status.
- Use the retro terminal look to present how our agent handles failed tool calls. Include a trace section.
Check what you need before you start
The skill needs an agent that can read SKILL.md-based skills. The font is a requirement only if you want the intended typeface to render. Without JetBrains Mono installed, the deck will fall back to another monospace font on your machine, and the look will differ.
The skill does not run scripts and does not use the network, according to its documentation. It is a set of styling instructions and an example file.
- Required: an agent that supports SKILL.md skills
- Recommended: JetBrains Mono font installed on the machine where you view the deck
- Not required: scripts, network access
Safety and readability notes
Because the skill runs no scripts and uses no network, the main risks are about the content you give it and how the slides look. Review the generated HTML as you would any file the agent produces before sharing it.
The dark neon style is deliberate. It can reduce readability when projected, especially on bright screens or in large rooms. Test the deck on the projector or display you will use.
- Review the generated HTML before sharing it outside your team
- Check contrast and text size on the actual display
- Do not rely on the template for light-background or printed handouts
Tips for better decks
Give the agent clear section content first, such as commands, outputs, and numbers, so the layout has real material to fit. Keep slide text short, since large mint-green type takes up a lot of space.
Use the example.html file as a reference for the visual style. If the result looks too dense, ask the agent to split content across more slides.
- Provide exact command output for trace and diff slides
- Keep each slide to one idea and a few lines of large text
- Ask for amber, green, or red tags to mark status, such as warning, pass, or fail
What people use it for
- A developer presenting a review of a new command-line tool with trace and benchmark slides.
- A team demoing an internal agent, showing how it handles tool calls in a terminal-style deck.
- A designer creating a retro technical talk about a dev tool, using the amber, green, and red tags for status.
- A community meetup presentation about a CLI where the dark theme suits the audience.
Frequently asked questions
Is the Cyber Terminal Deck agent skill free?
The skill is licensed under Apache-2.0, as listed on the item page. Check the license file in the source repository for the full terms before you reuse or redistribute it.
How do I install the deck-hermes-cyber skill?
Download the ZIP from our page and unzip the deck-hermes-cyber folder into ~/.claude/skills/ for personal use or into a project's .claude/skills/ folder. You can also upload the ZIP in the Claude apps under Settings → Capabilities → Skills.
What do I need to run this skill?
You need an agent that can read SKILL.md-based skills. JetBrains Mono is needed only if you want the intended font to render. The skill runs no scripts and uses no network.
Does the skill run code on my computer?
No. According to its documentation, the skill runs no scripts and uses no network. It is a styling and layout guide with an example HTML file.
Can I use this template for a formal client or corporate presentation?
It is not recommended. The dark neon style is deliberately stylized and may hurt readability when projected. It is also not suited to light-background or print-friendly slides.
Why does my deck look different from the example?
The most common cause is a missing JetBrains Mono font, since the deck falls back to another monospace font. Install the font on the viewing machine and check that the agent loaded the skill from the correct folder.

Our verdict
Use this skill if you are a developer making a review or demo deck about a CLI, agent, or dev tool, or a designer who wants a retro terminal look for a technical talk. Pick something else for formal corporate or client decks, light-background slides, or printed handouts, since the dark style is built for screens and may be hard to read when projected.
