About ECC
ECC is an MIT licensed open source agent harness performance optimization system that gives AI coding agents a coordinated engineering workflow — plan, test, implement, review, verify, remember, improve — for developers working in Claude Code, Codex, OpenCode, Cursor, and other harnesses.
About ctags
Universal Ctags is a maintained implementation of ctags that generates an index, or tag file, of the language objects found in source files, and it is aimed at developers and at the authors of text editors and other tools that need to locate those indexed items across many programming languages.
