On October 12th, Ted Haley published the Pensieve product page, offering a free, open-source Mac tool that builds a local index across code, documents and coding-agent sessions. It serves relevant passages to agents through the Model Context Protocol (MCP). Haley built it around a practical problem in AI-assisted coding: agents can spend time and tokens searching through a repository before they find the file that matters.…
