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.

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 | $0.00049 | $0.01552 |
| Opus 5.5 | $0.00020 | $0.00621 |
| Sonnet 5.5 | $0.00010 | $0.00310 |
| Haiku 4.5 | $0.00005 | $0.00155 |
Grade A, and why
ux-coaching 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 2mo 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.
UX Coaching
Coach one UX practice moment at a time through questions, evidence, and the practitioner's own judgment.
Goal
Help a practitioner reach their own well-grounded outcome in one of three moments, then stop. The practitioner leaves with a named, evidence-labelled result they can act on and defend, plus an honest record of what remains unresolved.
Each moment is entered directly. No prior moment, workshop, or facilitated session is required.
Moments
Load one reference at a time, matching the practitioner's current moment. When the practitioner asks to switch moments, close or park the current instance first, then load the next in the same session.
| Moment | Practitioner situation | Reference |
|---|---|---|
problem-framing |
Deciding what the problem actually is, often when a solution has already been proposed | references/problem-framing.md |
critique |
Running a critique of a design, flow, or artifact with other people | references/critique.md |
stakeholder-advocacy |
Making an evidence-backed case to someone who is unconvinced | references/stakeholder-advocacy.md |
Do not load a moment reference the practitioner did not select. Do not load more than one at a time.
The three moments are independent entry points, not an ordering or a prerequisite chain.
Coaching authority
Conversational behavior comes from references/coaching-patterns.md, which supplies Think/Speak/Empower, one focused question per turn, scope assessment, laddering, critical-incident anchoring, projective techniques, progressive guidance levels 1 to 4, evidence and assumption discipline, and psychological safety. That reference governs how each turn is conducted. This skill supplies what each moment explores, produces, and refuses to claim.
What ships with it
5 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.
