vhk vs sigma
vhk: VHK is a full-cycle AI coding harness designed to maintain stability regardless of the AI model or agent used. It wraps existing agents, providing persistent rules, context, and verification gates to streamline the development workflow and adapt to individual developer needs.; sigma: Sigma Code is an open-source coding agent designed for robust, long-running coding tasks, featuring native sandbox execution and durable sessions. It ensures changes are validated and provides evidence for task completion, supporting various interfaces like desktop, CLI, and TUI.

Features
vhk01Rule Portability: Synchronizes a single `RULES.md` to various AI agent rule files (e.g., Cursor, Claude, Copilot).
02Context & Session Persistence: Maintains session context and project brief through `.vhk/context.md` for seamless continuity.
03Evidence-Based Verification: Implements various gates like `verify`, `review`, and `receipt` to confirm completion with tangible evidence.
04Self-Evolving Rules: Accumulates lessons, patterns, and rule candidates from sessions in `.vhk/memory.json` to adapt and improve.
05Goal & Hard Stop Management: Defines and manages development goals, enforcing a `HARD_STOP` on repeated blockers.
sigma01Supports desktop, TUI, and CLI (run/inspect) interfaces for interaction.
02Durable sessions allow resuming, replaying, steering, canceling, and auditing after process interruptions.
03Native sandbox execution with OS-level isolation on Windows and Linux for secure operations.
04Tracks tests, validation, reviews, workspace deltas, and checkpoints in a typed evidence ledger.
05Connects to multiple AI model providers through a version-pinned Pi gateway.
