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: 1 finding, 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 | $0.00034 | $0.00541 |
| Opus 5.5 | $0.00014 | $0.00216 |
| Sonnet 5.5 | $0.00007 | $0.00108 |
| Haiku 4.5 | $0.00003 | $0.00054 |
Grade A, and why
dt-coaching-foundation 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 — 41 lines — stays where its author put it; the contents beside it link to each section on GitHub.
DT Coaching Foundation — Skill Entry
This SKILL.md is the entrypoint for the Design Thinking coaching foundation knowledge.
The dt-coach agent loads this skill at session start and during a coaching session to ground coaching behavior in a stable identity, enforce quality and fidelity expectations, navigate method transitions, persist and recover session state, and run the opt-in canonical deck workflow. The foundation knowledge stays constant across all nine Design Thinking methods.
Foundation references
Load the reference that matches the current coaching moment.
| Reference | When to load |
|---|---|
| coaching-identity.md | At session start and throughout — establishes coach identity, Think/Speak/Empower philosophy, boundaries, and the Progressive Hint Engine. |
| quality-constraints.md | Before any artifact generation — enforces fidelity rules, anti-polish stance, and quality-by-space expectations. |
| method-sequencing.md | At method transitions, space boundaries, and when the team asks what to do next — guides the nine-method sequence, transition protocol, next-method assessment, and non-linear iteration. |
| coaching-state.md | For persistence and session recovery — defines the coaching state schema, update rules, and recovery protocol. |
| canonical-deck.md | For opt-in canonical deck and customer-card generation — governs activation, offer points, and the customer-card branch. |
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.

dt-coaching-foundation is a skill published in the GitHub repository microsoft/hve-core (1,606 stars, last pushed today), licensed MIT. It adds 34 tokens to every session and 541 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 2026-08-30.
