Claude Code: fuzzy-search every session you've ever had

Two weeks ago Claude and I worked out why our staging deploys were flaky. Today it's happening again, and the answer is sitting in some session transcript on my disk. Which one? No idea. I remember a phrase from the conversation, not a session title.

Claude Code's own picker doesn't help here. claude --resume lists recent sessions for the current project, by title. If the title doesn't ring a bell, you're done. The transcripts themselves are JSONL files under ~/.claude/projects/, so the fallback is grepping JSON-encoded lines by hand and copy-pasting session ids into --resume. I did that maybe three times before deciding it was a tooling problem.

The palette

I run my agents inside herdr (the terminal-native agent multiplexer from the previous post), so I built the fix as a herdr plugin: herdr-agent-palette. Press a key, type what you remember, land where it was said. It fuzzy-searches your live panes and their scrollback too, but the section that fixed this particular pain is sessions: every Claude Code session on disk, searched by full transcript content. Not titles. Content.

Each row leads with how long since the session last moved and whether it's still open (●) or already closed (○); the preview shows the conversation with the query highlighted. Enter jumps to an open session's pane, and resumes a closed one in a fresh workspace, cwd set to where it ran. So: type staging deploy flaky, hit Enter, and ask the two-week-old session "that deploy fix, apply it here too".

That last part is what changed how I use it. Old sessions stopped being an archive I dig through and became something I casually jump back into.

It's a self-contained curses TUI, Python standard library only, with a clean-room fzy-style matcher that folds diacritics (Matejcek matches Matějček, which matters more than you'd think in a Czech codebase). Install is one command; the keybinding and the resume-command override (useful if you run multiple accounts) are in the README.

The transcripts were on disk all along. All they were missing was a search box.
