Show HN: Search-sessions – Search all your Claude Code session history in <300ms

Claude Code forgets everything between sessions. After months of heavy use, I had 1.6GB of JSONL session files buried in ~/.claude/projects/. Architecture decisions, debugging breakthroughs, and solutions I couldn't find again. There’s nothing more annoying that solving the same problem twice.

I tried RAG pipelines and local vector DBs, but they added complexity for a problem that's really just text search over structured files. So I built search-sessions: a single Rust binary that searches your session history directly. No database, no indexing step, no dependencies.

It supports two modes: index search (~18ms) for finding the right session, and deep search (~280ms with ripgrep, ~1s without) for matching against full message bodies. Each result includes the session UUID so you can resume any conversation with `claude --resume`.

The design choice that makes it work: skip the database entirely. JSONL files are already structured — just search them fast. Under the hood it's just files and a CLI, so it's easy to inspect, backup, and delete. You install it as a Claude Code skill, then ask "do you remember that auth refactor?" and Claude searches your history and picks up the thread. It also works with OpenClaw.

Curious what people think about exact vs fuzzy vs semantic search as a default — and which other coding CLIs you’d like supported.
