sorafujitani/ccsession: an fzf-powered session picker for claude --resume.

An fzf-powered session picker for claude --resume.

ccsession lists every Claude Code session under ~/.claude/projects, lets you fuzzy-find across all of your projects with a live preview pane, and resumes the one you pick in its original working directory.

Features

• Cross-project listing — every session from every project in one view, sorted by last activity.
• Three search modes — fuzzy (default), directory-only, and full-text grep over JSONL transcripts, with configurable mode-switch keys.
• Live preview — last 30 messages of the highlighted session, with timestamps and roles. In grep mode the matched query is highlighted in the preview so you can spot the hit at a glance.
• Faithful resume — chdirs back to the session's original cwd before exec'ing claude --resume, so paths and tooling Just Work.
• Single static binary — written in Go; the only dependency is a small TOML parser for the optional config file.

Requirements

ccsession depends on newer fzf actions such as transform, rebind, unbind, disable-search, and change-nth. The newest of those, change-nth, landed in fzf 0.58.0, so older versions may start but the mode switch bindings will not work correctly.

Install

Go

go install github.com/sorafujitani/ccsession/cmd/ccsession@latest

Version metadata is recovered from runtime/debug.ReadBuildInfo, so ccsession --version works for go install builds as well.

Pre-built binaries

Grab the ccsession_<ver>_<os>_<arch>.tar.gz for your platform from the Releases page, extract it, and drop the binary somewhere on your PATH:

tar xzf ccsession_0.1.0_darwin_arm64.tar.gz
install -m 0755 ccsession ~/.local/bin/

If macOS Gatekeeper complains:

xattr -d com.apple.quarantine ~/.local/bin/ccsession

Nix flake

nix run github:sorafujitani/ccsession             # one-off
nix profile install github:sorafujitani/ccsession # install into a profile

Homebrew

brew install sorafujitani/tap/ccsession

The formula lives in sorafujitani/homebrew-tap and GoReleaser refreshes it on every tagged release. fzf is installed as a dependency; the claude CLI must be installed separately.

Usage

ccsession                            # list -> fzf -> resume
ccsession list  [--grep Q] [--regex] # emit TSV rows to stdout
ccsession preview [--query Q] [--regex] <id> # render the preview pane (Q highlighted)
ccsession resume  <id>               # chdir to the session's cwd, exec `claude --resume`
ccsession --version
ccsession --help

Keys inside fzf

The three mode-switch keys are the defaults and can be overridden (see below).

Configuring the keybindings

If a mode-switch key clashes with your terminal, shell, or muscle memory, you can remap any of the three. Keys are resolved in this order (first wins):

CLI flags > environment variables > config file > defaults

The on-screen header is regenerated from the resolved keys, so the hint always matches what is active.

# CLI flags (highest precedence)
ccsession --bind-grep ctrl-r --bind-fuzzy alt-f

# environment variables
export CCSESSION_BIND_GREP=ctrl-r
export CCSESSION_BIND_DIR=ctrl-o
export CCSESSION_BIND_FUZZY=alt-f

Config file at ~/.config/ccsession/config.toml (lowest precedence before defaults; honors XDG_CONFIG_HOME). ccsession only reads this file — it never creates it, so create it yourself only if you want file-based overrides:

[keybindings]
grep  = "ctrl-r"
dir   = "ctrl-o"
fuzzy = "alt-f"

Any key you leave unset falls through to the next source. A key name must be lower-case fzf syntax (ctrl-r, alt-f, f1, …); the three keys must be distinct and must not be a reserved fzf event name (enter, change, …), or ccsession exits with an error instead of starting the picker.

How it works

1. ccsession list walks ~/.claude/projects/*/, reads the tail of each JSONL transcript in parallel, and prints one TSV row per session (id, epoch, relative time, cwd basename, label).
2. fzf consumes the TSV. The three key bindings swap fzf's matcher between fuzzy mode, directory-only mode, and grep mode (which reloads via ccsession list --grep <query> on every keystroke). The current query is also forwarded to the preview as ccsession preview --query <query> <id>, which highlights its matches in the rendered messages.
3. On Enter, ccsession resume <id> resolves the session's original cwd, chdirs into it, and execves claude --resume <id> so the resumed process fully replaces the picker.

Development

nix develop                    # Go + fzf + gopls + goreleaser
go build ./cmd/ccsession
