ECC (Everything Claude Code) is a comprehensive meta-harness toolkit for AI coding assistants. It provides a universal install system, lifecycle hooks, skill management, multi-agent orchestration, evaluation harnesses, and safety validation across multiple agent IDEs (Claude Code, Codex, Cursor, Gemini, OpenCode, and others). The codebase is primarily a Node.js CLI application (published as `ecc-universal`) with secondary Python and Rust components. It includes a sophisticated hook engine (pre/post bash, session lifecycle, tool use), a manifest-driven installer with ownership tracking and path-safety guards, an eval-harness framework with deterministic replay and effect-class isolation, a skill evolution system with provenance tracking, and a multi-agent proximity coordination system. The repository also bundles a large collection of domain-specific skills (video production, compliance checking, visa document translation, financial market data) and extensive documentation translated into multiple languages. While the core architecture is well-structured and demonstrates high craftsmanship in security-critical components, the codebase suffers from some duplication (e.g., taste-application/taste-distillation skills), legacy shims, and a sprawling surface area that increases maintenance burden. The Rust TUI control-plane (`ecc2/`) is explicitly alpha. Overall, it is a production-grade, actively maintained platform with strong engineering practices in its core modules.
This repository is a comprehensive, tool-agnostic skills and steering pack that teaches AI coding agents to perform AWS Well-Architected Framework reviews. It contains a curated reference corpus of over 2,000 markdown files (6 pillars, 307 best practices, 27 industry lenses) derived from official AWS documentation, plus per-tool adapters for 15 AI coding assistants (Claude Code, Cursor, Codex, GitHub Copilot, etc.). The repo also ships production-grade supporting tooling: a CI gating tool (wa-ci) that diffs structured review JSON against a baseline and blocks PRs on regressed gaps; an evaluation harness with blind multi-reviewer adversarial adjudication; a crawler to regenerate the reference corpus from AWS docs; and one-command installers. The core skill dispatches six parallel subagents (one per pillar) to keep the 2.2 MB corpus out of any single context window. Despite the extensive content, the repository has notable maintenance challenges: the reference snapshot will drift as AWS documentation evolves (users are responsible for regeneration); lens files are duplicated across `powers/` and `skills/` directories creating a sync hazard; and the flagship skill is explicitly deprecated in favor of a successor in Agent Toolkit for AWS. The evaluation harnesses and CI tooling are well-crafted and reusable, but the sheer scale of markdown files and platform-specific adapters makes ongoing synchronization complex.
