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 | $0.00065 | $0.02827 |
| Opus 5.5 | $0.00026 | $0.01131 |
| Sonnet 5.5 | $0.00013 | $0.00565 |
| Haiku 4.5 | $0.00006 | $0.00283 |
Grade A, and why
planner-identity 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 — 169 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Planner Identity
This skill is the shared scaffold for phase-based conversational planning agents that maintain persistent state under .copilot-tracking/<planner>/ and orchestrate work across six sequential phases. Per-planner identity protocols (sssc-planner.instructions.md, security identity.instructions.md, accessibility-identity.instructions.md, and the references/rai-identity.md and references/privacy-identity.md files in the rai-planner and privacy-standards skills) extend this base and contribute the planner-specific content listed under Scope of Inheritance.
Exploration-first questioning style, laddering, projective techniques, scope assessment, and raw-capture rules are defined in shared/coaching-patterns.instructions.md and apply on top of this base.
Disclaimer copy lives in the disclaimer-language skill; this base defines the cadence pattern, not the text.
Scope of Inheritance
Per-planner identity files inherit the following sections from this base and reference them by name rather than restating the content:
- State file convention
- Six-phase orchestration template (entry/activities/exit/artifacts/transition shape)
- Six-step State Protocol
- Resume Protocol (Resume Sequence + Post-Summarization Recovery)
- Question cadence mechanics (3-5 per turn, emoji checklist, the seven rules)
- Disclaimer cadence pattern (when the planner emits user-facing disclaimers)
- Error handling defaults
Per-planner identity files own the following sections and define them in their own file:
- Agent identity (name, purpose, voice, posture)
- Six-phase definitions (concrete phase ids, activities, gates, artifacts, transitions)
- Entry modes (per-planner enum and seeding behaviour)
- State schema (JSON shape with planner-specific keys, or a reference to a JSON schema file under
scripts/linting/schemas/) - Phase-specific question templates
- Cross-planner cross-link contracts (which sibling planners share state, and how)
- Planner-specific error cases not covered by the base defaults
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.

planner-identity is a skill published in the GitHub repository microsoft/hve-core (1,606 stars, last pushed today), licensed MIT. It adds 65 tokens to every session and 2,827 once invoked, about $0.0003 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 2026-11-07.
