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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00034 | $0.01636 |
| Opus 5 | $0.00017 | $0.00818 |
| Sonnet 5 | $0.00007 | $0.00327 |
| Haiku 4.5 | $0.00003 | $0.00164 |
Grade A, and why
rpi-quick 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 3d 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.
How it starts
The opening of the file, as written. The whole thing — 87 lines — stays where its author put it; the contents beside it link to each section on GitHub.
RPI
Goal
Coordinate one task through evidence, planning, execution, review, and explicit follow-up without duplicating the phase skills' detailed responsibilities.
Flow
- Assess research readiness from caller-supplied research, task details, decisions, and plan inputs.
- Activate
rpi-researchonly when evidence is missing, stale, contradictory, insufficient for planning, or when complexity, uncertainty, dependencies, risk, or a decision-critical question warrants investigation. Record Research dispositionexecutedand consume the primary artifact's Planning Readiness. - When evidence is adequate, record disposition
reusedorsatisfied-and-skippedwith the evidence that supports it. - Apply the
rpi-researchcontinuation contract. Continue to Plan without another stage-start command only when either an executed Research primary artifact records Planning ReadinessReady, or reused or satisfied-and-skipped evidence is adequate, and all applicable gates pass, blockers clear, and required confirmations are explicit. - When Research is
Blocked,Needs clarification, orNot ready, or another transition requirement is not met, stop in Research and record the blocker or next action.
- Activate
- Run
rpi-planto create or revise the ordinary Markdown plan and phase details. Itsrpi-plan-critiquegate is internal to planning and returns its disposition to the planning parent. - Run
rpi-implementfor approvedPxxandPxx-Txxwork. Consume its return, including completed and remaining markers, validation coverage, blockers, plan and detail updates, follow-up items, and readiness or the reason work is awaiting a significant or divergent user decision. - Run
rpi-reviewonce after Implementation returns and no affected work awaits a user decision. Compare the current plan, details, critique, descriptive changes record, and validation evidence. Record execution status separately from outcome. - Follow-up: route defects, decision gaps, research gaps, and residual work to their correct next destination.
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.

rpi-quick is a skill published in the GitHub repository microsoft/hve-core (1,436 stars, last pushed yesterday), licensed MIT. It adds 34 tokens to every session and 1,636 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 2026-09-03.
