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.

SkillSpector: 4 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

What it costs to keep this loaded
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 | $0.00022 | $0.02829 |
| Opus 5.5 | $0.00009 | $0.01132 |
| Sonnet 5.5 | $0.00004 | $0.00566 |
| Haiku 4.5 | $0.00002 | $0.00283 |
Grade A, and why
gh-code-scanning 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 1mo 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.

GitHub Code Scanning Skill
Overview
GitHub code scanning alerts are produced by static analysis tools such as CodeQL and Scorecard and surfaced in the GitHub Security tab. The GitHub Security tab is not accessible through the default MCP toolset, so this skill provides scripts for all read operations.
Prerequisites
| Requirement | Details |
|---|---|
pwsh |
PowerShell 7+; install from https://learn.microsoft.com/powershell |
gh CLI |
Installed and on PATH; install from https://cli.github.com |
| Auth | Run gh auth login or set GH_TOKEN; requires security_events scope |
| Scope | security_events for private repos; public_repo for public-only |
The repo scope also satisfies security_events. The gh CLI handles authentication automatically; no explicit token passing is needed in commands.
Get-CodeScanningAlerts.ps1 validates both prerequisites at startup and aborts with a targeted error message if either check fails.
Quick Start
Run this command to get a grouped summary of open code scanning alerts, sorted by frequency. This is the recommended first command when triaging a repository's code scanning posture.
pwsh scripts/Get-CodeScanningAlerts.ps1 -Owner "{owner}" -Repo "{repo}" -OutputFormat Json
This returns a JSON array of alert groups sorted by occurrence count, descending. Always use -OutputFormat Json when consuming results programmatically.
Parameters Reference
| Parameter | Type | Required | Default | Description |
|---|---|---|---|---|
-Owner |
String | Yes | GitHub organization or user that owns the repository | |
-Repo |
String | Yes | Repository name | |
-OutputFormat |
String | No | Table | Output format: agents must always use Json for programmatic consumption; GroupedJson is accepted as an alias for Json |
-Branch |
String | No | main |
Branch to scope alert results |
-IncludeDismissedStillDetected |
Switch | No | Also report dismissed alerts that are still detected on the branch, as groups with Kind set to dismissed-still-detected |
What ships with it
4 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.

gh-code-scanning is a skill published in the GitHub repository microsoft/hve-core (1,606 stars, last pushed today), licensed MIT. It adds 22 tokens to every session and 2,829 once invoked, about $0.0001 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 2026-09-03.
