Feature & Specification Comparison

Specification	Backscroll soren-achebe Command Line	Sage PsYcGoD Command Line
Summary	Answers "what did that command print?" from your real terminal history: a per-command PTY session recorder (OSC 133) stores every command's full output, exit code, cwd, and duration in local SQLite/FTS5, and the MCP server searches, retrieves, and diffs those outputs — secret redaction on by default before anything reaches the model.	Local-first CLI and MCP wrapper for AI coding agents. Routes shell commands through sage run --, stores command history locally, and returns compressed terminal output to reduce context noise.
