Superpowers is a composable skill framework and development methodology for coding agents. It prompts clarification before implementation, confirms a specification in readable chunks, and guides worktrees, plans, TDD, subagent execution, two-stage reviews, and branch finishing. It supports several agent harnesses, including Claude Code, Codex, Cursor, and OpenCode, but must be installed separately for each one.

ECC provides a modular environment of specialized subagents, development skills, rules, commands, session state, and security hooks for planning, testing, review, debugging, and reusable knowledge. It is primarily distributed as a Claude Code plugin, with adapters and configuration for Codex, OpenCode, Cursor, and other assistants. Its selective installer lets advanced users add only the components needed for their workflow rather than adopting the entire collection.

Claw Code contains a Rust implementation of the `claw` terminal agent harness that can be built from source and used for diagnostics, one-shot prompts, and interactive sessions with an API key. The repository presents itself as an agent-planned and maintained museum exhibit, warns that the same-named crates.io package is the wrong install, and points practical users to LazyCodex or Gajae-Code.

OpenCode is an open-source coding agent for the terminal. Its built-in build agent handles development work, the plan agent is read-only for analysis and exploration, and a general subagent supports complex searches and multistep tasks. The project also offers a beta desktop app for macOS, Windows, and Linux, so users can choose a CLI or desktop workflow.
