How to use the Signal strategy decision memo deck agent skill
Updated · written with AI from the project's own documentation and checked against our catalogue data
The html-ppt-zhangzara-signal skill gives an AI agent a ready-made visual template called Signal for building a single-file HTML slide deck. Its named example is a strategy memo that sets out whether a company should act now on a decision or hold, with options, risks and a recommendation. This guide explains what the skill changes, how to install it, how to ask for it in plain language, and where to be careful, so you can produce a sober board or executive pre-read deck without starting from a blank page.
Strategy Decision Memo Decknexu-io/open-design · Apache-2.0 Download the skill Quick start
- 1Download the ZIP. Get the skill ZIP from this page. The skill folder contains SKILL.md and template.json according to the file list.
- 2Install the skill. Unzip it into ~/.claude/skills/ for personal use or into .claude/skills/ in a project, or upload it under Settings → Capabilities → Skills in the Claude apps.
- 3Start a new conversation. Open a fresh chat so the agent loads the newly installed skill.
- 4Describe the decision. State the decision, the audience (for example CEO and strategy team), the deadline and the source material you can provide.
- 5Supply your real figures. Give the must-keep numbers and facts so the agent replaces placeholders with them rather than inventing content.
- 6Review and check. Open the generated HTML in a browser, check every claim against your sources and adjust the slide count as needed.
What the Signal skill makes the agent do
An agent skill is a folder of instructions that an AI agent loads when your request matches it. This one tells the agent to use the Signal template: a deep navy background, bone-coloured paper, a single muted-gold accent and a formal, dense layout. The template is a complete single HTML file, so the result opens in a browser.
The skill's own description frames it as a decision-grade deck for a CEO or strategy team. The agent keeps the template's fonts, palette and decorative elements and replaces the sample text with your headlines, numbers and sections. The skill asks it not to swap in other fonts or colours, or to change the layout grid, so the deck looks consistent from slide to slide.
Install the skill in Claude
You have two routes. The first is to download the skill ZIP from this page and unzip it into your personal skills folder, ~/.claude/skills/. To limit it to one project, unzip it into the .claude/skills/ folder inside that project instead.
The second route is to upload the ZIP in the Claude apps under Settings → Capabilities → Skills. Use whichever matches how you work. After installing, start a new conversation so the agent can see the skill.
- Personal use across projects: ~/.claude/skills/
- Single project: .claude/skills/ inside the project folder
- Claude apps: Settings → Capabilities → Skills
Trigger the skill with a natural request
You do not need a special command. Describe the deck you want and mention the purpose. The skill's trigger words include board, strategy, business review, board pre-read deck, corporate strategy and html slides, so phrasing like the examples below should match it.
Give the agent your decision, audience and the material it can rely on. The example prompt in the skill asks for the audience, the decision target, source materials, deadline and any numbers that must stay exactly as written, before it builds the deck.
- Make a board pre-read deck in HTML on whether we should monetise the plugin registry now or hold. Options, risks and a recommendation.
- Use the Signal strategy template to build a decision memo deck for our CEO and strategy team. Here are our notes and the Q3 numbers.
- Turn this strategy memo into an html slide deck with a clear recommendation slide, in the navy and gold corporate style.
Work through the template with the agent
The skill sets a working order. The agent copies the template file into your workspace as the working file, then replaces placeholder content with your real headlines, body copy, numbers, names, dates and section labels. If you need more slides than the template's demo, the agent duplicates a slide with a suitable layout. If you need fewer, it removes slides from the end and updates page numbers.
If a slide needs a layout the template does not have, the skill tells the agent to design one using the same fonts, palette and decorative style rather than switching templates. Review the result against your own material before sharing it.
- The demo deck has 18 slides.
- Keep the decorative elements such as corner brackets, paper grain and geometric shapes; the skill treats them as part of the identity.
- The output is one self-contained HTML file.
Safety notes: scripts and network
The listing states that this skill runs no scripts and uses no network access, and it lists no separate requirements. Because it is a set of instructions and a template, it does not need extra software beyond your agent environment.
The main risk is the content, not the code. The template only organises what you give it. If you supply no real figures or sources, the agent may write plausible-sounding claims. Check every number and claim in the deck before a board sees it.
Licensing: the directory lists this item under Apache-2.0. The skill text says it is vendored from an MIT-licensed upstream project and that the upstream licence should be redistributed with copies of the template. The file list on this page shows only SKILL.md and template.json, so check the ZIP contents for the licence file and any example.html that the instructions mention.
- No scripts are run and no network use is listed.
- Verify all numbers and claims yourself.
- Check the ZIP for the licence file the skill refers to.
What people use it for
- A strategy team preparing a board pre-read on whether to monetise a plugin registry now or hold.
- A finance lead writing an executive memo that needs a clear recommendation slide.
- A consultant who wants a formal, weighty visual style for a client decision deck.
- An adviser building a short options-and-risks deck for a leadership review.
Frequently asked questions
How do I install the html-ppt-zhangzara-signal skill?
Download the skill ZIP from this page and unzip it into ~/.claude/skills/ for personal use, or into .claude/skills/ inside a project. You can also upload the ZIP in the Claude apps under Settings → Capabilities → Skills.
Does this skill need any requirements or extra software?
The listing states that nothing extra is required, that it runs no scripts and that it uses no network access. It works through the agent environment you already use.
Is the Signal skill free to use?
The directory lists the item under the Apache-2.0 licence. The skill text says the template is vendored from an MIT-licensed upstream project, so check the licence file included with the download for the terms that apply.
What kind of presentation is this skill best for?
It suits strategy or finance staff preparing board or executive pre-reads, and consultants who want a formal style. It is not suited to playful, casual or fast-paced presentations, because the style is deliberately sober and dense.
Will the agent make up numbers for my deck?
The template only organises content. If you do not provide real figures or source material, the agent may fill gaps with plausible-sounding claims, so you must check every number before using the deck.
What are alternatives to this skill for building HTML slides?
The source does not compare this skill with other tools, so this guide cannot make that comparison. If you need a different visual style, look for another template whose look fits your audience.

Our verdict
Use this skill if you need a sober, dense, navy-and-gold HTML deck for a board or executive decision and you can supply the real facts. Pick something else if you want a playful or fast-moving presentation, or if you lack the figures and sources needed to back up the recommendation.
