HVE Core is a collection of agents, prompts, coding instructions, and skills for building repeatable software-development workflows with GitHub Copilot. It is intended for individuals and teams that want structured AI-assisted research, planning, implementation, and review, while the catalogue entries provide many of its reusable workflow components.
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 | $0.00038 | $0.04142 |
| Opus 5 | $0.00019 | $0.02071 |
| Sonnet 5 | $0.00008 | $0.00828 |
| Haiku 4.5 | $0.00004 | $0.00414 |
Grade A, and why
demo-setup 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 yesterday.
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.
How it starts
The opening of the file, as written. The whole thing — 322 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Demo Setup
Overview
Creates demo-ready prototypes by guiding you through a simulated Design Thinking Coach session with a customer persona, then scaffolding a hi-fi prototype. The skill generates a customer persona brief with realistic conversation seeds, accelerates through DT Methods 1 through 6 with simulated customer dialogue, and scaffolds a runnable hi-fi prototype directly at Method 7. The result is a complete, runnable demo with a presenter's walkthrough guide and a video script for recording.
Primary audience: new users learning HVE Core tools.
Core design constraints:
- Every demo starts with a customer persona brief that drives the simulated conversation.
- DT Coach interactions use accelerated pacing (2 to 3 exchanges per method) for demo efficiency.
- Step 4 scaffolds the hi-fi prototype directly, handling all scaffold generation and experiment framing.
- Presenter's guide included so demos are repeatable without memorizing the flow.
- Demo video script generated for recording a polished walkthrough video.
Prerequisites
- DT Coach agent accessible (provided by the HVE Core extension)
.copilot-tracking/directory exists at the workspace root
Quick Start
Run a demo with custom inputs:
- Invoke
/demo-setupwithcustomer={name},industry={vertical}, and optionallypersonaandproblem. - The DT Coach walks through Methods 1 through 6 with a generated persona and conversation seeds.
- At Method 7 the skill scaffolds a runnable prototype.
- Open
index.htmlin a browser and follow the presenter's guide inREADME.md.
When to Use
- Setting up a demo for a customer, partner, or internal team to showcase HVE Core tooling
- Onboarding new users who need to see the DT Coach and prototype workflow end to end
- Preparing a conference talk, workshop, or training session that walks through the tools
- Creating a reference demo that others can replicate independently
When Not to Use
- Running a real Design Thinking engagement with actual stakeholders (use the DT Coach directly)
- Building a production prototype without the demo scaffolding and walkthrough
- Creating a static slide deck or documentation (use the canonical deck or PowerPoint skill)
- The audience already knows the tools and needs advanced workflow guidance
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

demo-setup is a skill published in the GitHub repository microsoft/hve-core (1,453 stars, last pushed today), licensed MIT. It adds 38 tokens to every session and 4,142 once invoked, about $0.0002 per session on Opus 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 2026-09-10.
