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 | $0.00025 | $0.00497 |
| Opus 5 | $0.00013 | $0.00249 |
| Sonnet 5 | $0.00005 | $0.00099 |
| Haiku 4.5 | $0.00003 | $0.00050 |
Grade A, and why
prompt-analyze 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 6d 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.

The opening of the file, as written. The whole thing — 55 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Prompt Analyze Compatibility Skill
Goal
Preserve legacy prompt-analyze activation while producing independent static and behavior evidence through hve-builder in read-only review mode.
Flow
- Translate
promptFilestotargetsand infer current open or attached prompt-engineering artifacts when omitted. - Activate
hve-builderwithmode=review, the targets, analysis requirements, requested behavior-test fidelity, and any caller-owned evidence root. - Keep source artifacts read-only. Permit only review, behavior-test, and requested validation evidence writes.
- Return the static verdict, behavior-test fidelity and verdict, validation as
Not requestedunless the caller requested it, overall outcome, findings summary, and report links.
Inputs
promptFiles: existing prompt, instruction, agent, subagent, skill, reference, or template files to reviewrequirements: optional purpose, criteria, or behavior to emphasizefidelity: optionalsimulationornativerequest, subject to HVE Builder Tester safety preconditionsevidenceRoot: optional caller-owned HVE Builder evidence path
Success Criteria
- Source artifacts are unchanged.
- Static review and required behavior testing complete or carry an explicit deferral.
- Findings use the HVE rubric severity and fidelity contracts.
- The response links the durable review and behavior reports.
Constraints
- Do not dispatch retired named lifecycle workers.
- Do not research, fix, refactor, or create source artifacts in this mode.
- Do not describe simulation as native runtime evidence.
Stop Rules
- Stop Pass when
hve-builderreview mode returns Pass. - Preserve Revise, Deferred, or Blocked and its rerun condition.
- Stop before any source edit.
Handoff
Recommend prompt-builder for approved improvements or prompt-refactor for behavior-preserving cleanup. Both route changes through hve-builder.
Final Response Contract
Return targets, static verdict, behavior-test profile and fidelity, behavior verdict, validation result (Not requested unless requested), overall outcome, top findings, report links, and next action.
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.

prompt-analyze is a skill published in the GitHub repository microsoft/hve-core (1,436 stars, last pushed today), licensed MIT. It adds 25 tokens to every session and 497 once invoked, about $0.0001 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 2026-08-30.
