Score: 7.8/10 (Innovation: 8, Technical: 8, Documentation: 8, Utility: 7)

ctx is an open-source Rust CLI that indexes local coding agent session transcripts (Claude, Codex, etc.) into a searchable Tantivy index, enabling fast lexical and semantic search over past agent history. Its paid pro add-on provides 'git blame for agent sessions,' mapping commits/lines/PRs back to the original agent transcript and tool calls, helping agents recover rationale, constraints, and failed approaches without lossy memory compaction.

Target audience: backend devs, AI agent developers, devops, engineering teams using coding agents
