sx — session explorer for AI coding harnesses

A terminal TUI that gathers the chat sessions every AI coding harness leaves on your machine — Claude Code, Codex, Gemini CLI, and more — into one browsable, groupable, deletable view. Think of it as a terminal-native alternative to Claude Code UI, covering every harness at once.

Status: functional. Browsing, search, grouping, permanent deletion with Markdown export, and orphan cleanup all work across Claude, Codex, Gemini, and opencode.

Why

Each harness scatters sessions in its own format and location: Claude under ~/.claude/projects/<encoded-cwd>/, Codex in a date tree under ~/.codex/sessions/, Gemini as mutation logs under ~/.gemini/tmp/<hash>/, and opencode as rows in a shared SQLite database. Over time these pile up alongside orphaned folders pointing at projects you deleted long ago. sx reads them all, lets you scroll any transcript, and permanently removes the ones you no longer want.

Features

• Unified browser — sessions grouped by harness, then by project.
• Scrollable transcripts — normalized rendering across every harness.
• Orphan detection — finds session folders whose project is gone, plus stray temp files, and reports why each is flagged.
• Permanent delete with guardrails — dry-run preview, typed confirmation for bulk operations, a path allowlist, an active-session guard, and an append-only deletion log. No accidental rm -rf.
• Pre-delete Markdown export — optionally archive a transcript to Markdown before removing it (also available as a standalone export action).
• Forward-looking — harnesses you have not installed yet appear greyed out and light up the moment their session store shows up on disk.

Run it

You need uv. Pick one of the two ways below.

Option A — run straight from GitHub, no install (uvx)

uvx fetches, builds, and runs sx in a throwaway environment — nothing is added to your PATH:

uvx --from git+https://github.com/junxit/agentic-session-explorer.git sx

Typing that every time is a mouthful, so add an sx alias to your shell. The alias also sets SX_NO_UPDATE_CHECK=1, because uvx already pulls the latest build — the in-app "update available" prompt would be redundant here.

zsh — append to ~/.zshrc:

alias sx='SX_NO_UPDATE_CHECK=1 uvx --from git+https://github.com/junxit/agentic-session-explorer.git sx'

bash — append to ~/.bashrc (Linux) or ~/.bash_profile (macOS):

alias sx='SX_NO_UPDATE_CHECK=1 uvx --from git+https://github.com/junxit/agentic-session-explorer.git sx'

fish — append to ~/.config/fish/config.fish:

alias sx 'env SX_NO_UPDATE_CHECK=1 uvx --from git+https://github.com/junxit/agentic-session-explorer.git sx'

Then reload (source ~/.zshrc, etc.) and run sx, sx list, sx --version — arguments pass straight through the alias.

uvx caches builds, so a plain run may reuse a recent one. To force the newest commit, add --refresh to the alias's command, or pin a released tag with ...explorer.git@v0.2.0.

Option B — install as a tool (recommended for regular use)

This puts a persistent sx on your PATH:

uv tool install git+https://github.com/junxit/agentic-session-explorer.git

(From a local clone, uv tool install . works too.)

Upgrade:

uv tool upgrade sx
# or force the very latest commit on main:
uv tool install --force git+https://github.com/junxit/agentic-session-explorer.git

Uninstall:

uv tool uninstall sx

When you run an installed sx interactively, it checks GitHub at most once a day for a newer release and prints a one-line notice (the TUI shows a toast). The check is cached, times out fast, fails silently, and never blocks startup. Turn it off with --no-update-check or by exporting SX_NO_UPDATE_CHECK=1.

Usage

sx              # launch the interactive TUI
sx list         # list every discovered session as plain text
sx harnesses    # show all known harnesses and their status
sx version      # show the installed version and check for a newer one
sx update       # show (or, with --run, execute) the upgrade command

Keys (in the TUI)

Key	Action
↑/↓ or j/k	Move the selection
enter	Open the highlighted session's transcript
g / G	Jump to top / bottom of a transcript
m	Cycle grouping: project → date → recency
/	Filter by title or project (live)
e	Export the highlighted session to Markdown
d	Permanently delete the highlighted session (with preview)
o	Open the orphan-cleanup screen
r	Re-scan all harness stores
q	Quit

A session written within the last 90 seconds is flagged ● LIVE; deleting one requires typing DELETE to confirm. Bulk orphan deletion requires typing DELETE <n>. Exports default to ./session-exports/; every deletion is appended to ./sx-deletions.log.

Loading

Every adapter normalizes its harness into the same Session and Message types, so the transcript viewer, the exporter, and the delete flow are each written once and work for all harnesses — present and future. Most harnesses store one file per session; opencode keeps all sessions as rows in a shared SQLite database, so its adapter subclasses HarnessAdapter directly and deletes a session's rows (and its session_diff sidecar) without ever touching the database file or other sessions. Its shared log/ files are left alone.

Development

uv sync --extra dev
uv run sx list
uv run pytest

Releasing

The update check compares the installed version against the latest GitHub release (falling back to the highest vX.Y.Z tag). To publish an update:

1. Bump version in pyproject.toml and __version__ in src/sx/__init__.py.

2. Commit, then tag and release:

   git tag v0.2.0 && git push --tags
   gh release create v0.2.0 --generate-notes

Installed copies will then prompt their users to upgrade.

Safety

sx deletes permanently — there is no trash or undo. To compensate, deletion is gated behind a preview, typed confirmation for bulk actions, a guard that refuses to touch anything outside known harness store roots, and a guard that refuses to delete a session that is currently being written. Every deletion is appended to sx-deletions.log.
