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 | $0.00035 | $0.00613 |
| Opus 5.5 | $0.00014 | $0.00245 |
| Sonnet 5.5 | $0.00007 | $0.00123 |
| Haiku 4.5 | $0.00003 | $0.00061 |
Grade A, and why
git-merge 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 — 46 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Git Merge and Rebase
Goal
Run a merge, rebase, or rebase --onto sequence from the current branch with explicit inputs, optional review pauses, and a completion summary. Follow every step even when the repository appears clean so results stay consistent and traceable.
Conventions
Read references/merge-conventions.md and follow its integration, authorization, account-change, and execution-evidence rules.
Inputs
operation(optional, defaultmerge):merge,rebase, orrebase-onto.branch(required): the branch or ref to merge, or the rebase target. Ask for it when it is missing.onto(required forrebase-onto): the new base.upstream(optional, used byrebase-onto): the branch or commit that bounds the commits to move.conflict-stop(optional, defaultfalse): whentrue, pause after each set of conflict fixes for user review before continuing.
Flow
- Resolve the inputs. Ask for
branchwhen it is missing, and forontowhenoperationisrebase-onto. Record the active branch and the inputs. - Prepare the workspace as the merge conventions define, then run the command they define for the selected
operationand capture its output. Without conflicts, continue at step 5. - Resolve conflicts as the conventions define, and keep each file's resolution and rationale for the summary.
- Honor review pauses. When
conflict-stopistrue, summarize the fixes with a checklist of touched files and wait for explicit user confirmation before continuing. Answer follow-up questions and adjust resolutions from user feedback. - Continue or complete the operation as the conventions define, or abort when the user directs it.
- Execute an authorized ordinary push under those conventions; otherwise leave the result local without soliciting publishing approval. Summarize the integration, linked conflict resolutions, stash state, actual push/account-cleanup outcomes when applicable, and remaining follow-up.
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.

git-merge is a skill published in the GitHub repository microsoft/hve-core (1,606 stars, last pushed today), licensed MIT. It adds 35 tokens to every session and 613 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 2026-10-08.
