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 | $0.00051 | $0.03070 |
| Opus 5.5 | $0.00020 | $0.01228 |
| Sonnet 5.5 | $0.00010 | $0.00614 |
| Haiku 4.5 | $0.00005 | $0.00307 |
Grade A, and why
hve-slides 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 — 232 lines — stays where its author put it; the contents beside it link to each section on GitHub.
HVE Slides
Goal
Deliver a source-backed HTML presentation that a person can present, navigate and share.
Create new decks under slides/<deck-slug>/ or make scoped updates to an existing deck.
For a review-only request, return findings without changing deck source.
For already-authored sources, render one standalone HTML file without researching or
rewriting content. Authoring and rendering share this skill's canonical template and
bundler in repository, plugin and VSIX installations. Resolve hve-slides by name and
use the loaded skill root for its scripts, references and templates; caller outputs
never belong inside the installed skill.
Success Criteria
- For authoring, the requested story is covered with dated sources, accurate terminology and explicit limits.
- For render-only requests, supplied content and order are preserved without research or narrative edits; source/output stay in caller-owned locations.
- The deck uses discrete slides, readable examples and predictable presenter controls.
- The presenter bar, slide footers and walkthrough controls follow the shared bottom chrome unless the user approves a different design.
- Slides and walkthroughs support keyboard use, meaningful reading order, readable reflow, sufficient contrast and reduced motion, with evidence from the delivered HTML.
- Scripted conversations, reconstructed UI and actual execution are distinguishable.
- Source edits, generated output, local checks and browser evidence describe the same revision.
- Generated bundles pass the bundler's security checks and carry its provenance block; the checks are never bypassed and generated HTML is never hand-edited.
- The handoff names the viewable file and exact build or sharing command; unfinished checks remain visible.
Inputs and Scope
Infer the deck from an explicit path or the currently discussed presentation when unambiguous. For a new deck, resolve its topic, audience, purpose, approximate duration, source date and delivery needs. Reuse supplied answers; ask one focused question only when a missing decision would materially change the story, write boundary or delivery.
What ships with it
37 files 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.

hve-slides is a skill published in the GitHub repository microsoft/hve-core (1,606 stars, last pushed today), licensed MIT. It adds 51 tokens to every session and 3,070 once invoked, about $0.0002 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 2026-09-14.
