showagent

showagent — every AI coding session on your machine, in one TUI.
Browse, search, resume, branch — and convert a conversation from one agent to another.

Started debugging in Codex and want Claude's take? Press x. Your conversation moves with you — every user and assistant turn, rewritten in the target agent's native session format.

Why

You use more than one coding agent now — most of us do. But every agent buries its sessions in its own format under its own dot-directory, and yesterday's context is trapped in whichever tool you happened to start it in. showagent reads the session stores straight off disk and gives you one searchable picker for all of them. It is the only TUI that combines browse + search + resume + branch + convert across agents.

• One list for everything — sessions from every agent, grouped by workspace, fuzzy-searchable, newest first.
• Resume or branch anywhere — reopen a session in its own CLI, or fork a local copy to try a different direction.
• Convert between agents — rewrite a session into another agent's native format so that agent's own resume just works. Originals are never modified; conversions are written atomically.
• 100% local — one static binary that reads your own files. No server, no telemetry, no account.

Supported agents

Agent	CLI	Sessions read from	Env override	Convert from	Convert to
Codex	codex	~/.codex/sessions/**/*.jsonl	CODEX_HOME	✅	✅
Claude Code	claude	~/.claude/projects/**/*.jsonl	CLAUDE_HOME	✅	✅
Gemini CLI	gemini	~/.gemini/tmp/<project>/chats/	GEMINI_CLI_HOME	✅	✅
OpenCode	opencode	opencode.db, via the opencode CLI	OPENCODE_DATA_HOME	✅	✅
jcode	jcode	~/.jcode/sessions/*.json	JCODE_HOME	✅	✅

Notes:

• OpenCode stores sessions in a SQLite database, so every OpenCode operation (discover, export, import, delete) goes through your own opencode CLI — showagent never writes into the database directly. OpenCode and jcode only appear when their CLI is installed.
• Converting to an agent requires that agent's CLI on PATH, so the result can actually be resumed.
• jcode is a niche, experimental agent CLI. Its support is auto-hidden: if no jcode binary is on PATH, showagent never shows it.
• Platforms: Linux and macOS (amd64 + arm64). Windows (amd64) builds are released but experimental: resume runs the agent as a child process instead of replacing showagent.

Install

# Homebrew (Linux/macOS)
brew install aytzey/tap/showagent

# install script (Linux/macOS, puts the binary in ~/.local/bin)

# Go 1.25+
go install github.com/aytzey/showagent/cmd/showagent@latest

Or grab an archive from the releases page — linux/darwin amd64 + arm64, windows amd64 (experimental).

Quick start

showagent                  # open the interactive picker
showagent list             # plain table of every session
showagent list --json      # the same, machine-readable
showagent resume latest    # reopen the most recent session, any agent
showagent --help           # full CLI help

Keybindings

Key	Action
↑/k, ↓/j, pgup/pgdn	Move through sessions
/	Fuzzy search across agent, workspace, session id, and messages
enter	Resume the selected session in its own CLI
1..9	Toggle provider visibility, numbered as listed in the header bar
p	Cycle the preview column: first → latest → first + latest message
space	Collapse or expand the selected workspace group
o	Cycle the convert target for the selected session
t	Cycle the convert scope: all turns, or latest 200/100/50/20/10
x	Convert to the target agent and select the new session
n	Branch: create a full local copy of the session
y	Toggle yolo resume (skip the agent's permission prompts)
C	Compound: resume with a learnings-capture prompt (see below)
d, del, backspace	Delete the session — second press confirms, moving disarms
r	Rescan session stores (keeps cursor, search, and filters)
?	Toggle the full keybinding overlay
esc	Clear search / close overlay / cancel an armed delete (never quits)
q, ctrl+c	Quit

Scripting

showagent list --json emits an array sorted newest-first — the field names are a stable contract:

[
  {
    "id": "1f7c9a2e-4b31-4c8e-9d02-8a5e3f6b1c44",
    "provider": "codex",
    "workspace": "/home/you/code/api-server",
    "updated": "2026-07-08T19:51:25Z",
    "first_message": "Add rate limiting to POST /v1/charges",
    "last_message": "the redis TTL test is flaky - mock the clock"
  }
]

showagent resume <id|latest> [--yolo] resumes without the picker, so a shell alias can reopen your last session in one keystroke. Exit codes: 0 success, 1 error (including "no sessions found"), 2 usage. When stdout is not a terminal, plain showagent prints the list table, so pipes just work.

How it compares

Great tools exist for running agents in parallel — showagent is about the sessions they leave behind. claude-squad and ccmanager orchestrate multiple live agents in tmux sessions and git worktrees, which is the right choice when you want several agents working at once. Agent Sessions is a polished macOS app for browsing session history across many agents. showagent is the history-first, terminal-first take: a single cross-platform binary that reads the session stores on disk, resumes and branches from them — and is the only one of the group that converts a session from one agent's format to another's.

Compound engineering

Press C on a session and pick an agent. showagent resumes the session there and starts it on a compound-engineering pass: review what was solved, then record the durable learnings as markdown.

Learnings are pooled per project but shared across agents: each workspace gets a directory under ~/.showagent/learnings/<project>/ (override with SHOWAGENT_LEARNINGS_DIR) that every agent reads and writes. Picking an agent that did not create the session converts it first, so it has full context.

showagent setup installs the companion compound-engineering plugin into the Codex and Claude Code CLIs found on the machine. It is idempotent and only installs what is missing.

FAQ

Is my session data sent anywhere? No. showagent is fully local: it reads session files where the agents left them and makes no network calls. There is no server, no telemetry, and no account. Message previews additionally redact password-like strings and API keys before rendering (covered by tests in internal/session/session_test.go). Release archives ship with a SHA256SUMS file, and releases after v0.7.0 also carry GitHub build provenance — verify with gh attestation verify <file> --repo aytzey/showagent.

How does conversion work? Conversion extracts the user and assistant turns from the source transcript and writes a brand-new session in the target agent's native format (for OpenCode, via opencode import), so the target's own resume command picks it up. The original session is never modified, and files are written atomically — a crash cannot leave a half-written session in another tool's store. It intentionally does not copy tool-call internals, approval history, encrypted reasoning blobs, or provider attachments: those are private to the source agent and would not replay correctly anyway. t trims the scope to the latest N turns before converting.

What does delete actually do? Codex sessions are deleted through codex delete --force; OpenCode through opencode session delete (which cascades inside its database); Claude Code, Gemini, and jcode by removing the session file. Delete always takes two presses, and moving the cursor disarms it.

Windows? Binaries are released and the whole TUI works, but resume semantics are approximated (child process instead of exec), so Windows is labeled experimental until it has seen real use.

A session is missing from the list. Run showagent list with no sessions found and it prints exactly which directories were scanned and which env vars override them. r rescans in-place after you start a new conversation.

Adding a provider

A provider is one self-contained file implementing the 8-method interface in internal/session/provider.go — around 250 lines including discovery, resume arguments, transcript extraction, and conversion. gemini.go (file-based store) and opencode.go (CLI-based store) are the two templates. Register it in the registry slice and the TUI picks up badges, filter keys, and convert targets automatically. Add a matching env override so its tests stay hermetic. Issues and PRs welcome.
