HVE Core
HVE Core RPI (Research, Plan, Implement, Review) workflow with Git commit, merge, setup, and pull request prompts
HVE Core provides the flagship RPI (Research, Plan, Implement, Review, Discover) workflow for completing complex tasks through a structured five-phase process. The RPI workflow dispatches specialized agents that collaborate autonomously to deliver well-researched, planned, and validated implementations. This collection also includes Git workflow prompts for commit messages, merge operations, repository setup, and pull request management.
This collection includes agents for:
- RPI Agent — Autonomous orchestrator that drives the full five-phase workflow
- Task Researcher — Gathers context, discovers patterns, and produces research documents
- Task Planner — Creates detailed implementation plans from research findings
- Task Implementor — Executes plans with progressive tracking and change records
- Task Reviewer — Validates implementations against plans and project conventions
- PR Review — Comprehensive pull request review ensuring code quality and convention compliance
Git workflow prompts for:
- Commit Messages — Generate conventional commit messages following project standards
- Merge Operations — Handle merges, rebases, and conflict resolution workflows
- Repository Setup — Initialize repositories with recommended configuration
- Pull Requests — Create and manage pull requests with linked context
Supporting subagents included:
- Codebase Researcher — Searches workspace for code patterns, conventions, and implementations
- External Researcher — Retrieves external documentation, SDK references, and code samples
- Phase Implementor — Executes single implementation phases with change tracking
- Artifact Validator — Validates implementation work against plans and conventions
- Prompt Tester — Tests prompt files by following them literally in a sandbox
- Prompt Evaluator — Evaluates prompt execution results against quality criteria
Skills included:
- PR Reference — Generates PR reference XML files with commit history and diffs for pull request workflows
