OpenLore vs whetstone

OpenLore: OpenLore turns any evolving codebase into a navigable knowledge graph backed by OpenSpec living specifications. It maintains persistent architectural context across AI agent sessions, reducing token consumption for orientation from 15,000-50,000 to about 1,000-3,000 tokens. The three-layer system includes static analysis, spec generation, and an MCP agent runtime with 45 tools.; whetstone: Whetstone is a Claude Code plugin that enforces disciplined development workflow: plan before coding, verify before claiming done, find root cause before patching, review before merge. It bundles agents, skills, commands, and a skill distillery for PHP, Python, TypeScript, React, and infrastructure workflows.
