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 hosted service, no telemetry, no account.

Supported agents

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.
• The picker only offers hand-off targets whose CLI is on PATH, so it never strands a conversion. Scripted conversion to file-backed agents can still prepare a session before their CLI is installed; OpenCode always requires its CLI because imports go through OpenCode itself.
• 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.

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 convert latest --to claude --dry-run
                           # preview exactly what a hand-off would carry/drop
showagent info latest      # exact resume command + storage location
showagent mcp              # serve session history to MCP-capable agents (stdio)
showagent mcp --read-only  # same search/transcript tools, without tools that write copies
showagent mcp --allow-secrets
                           # explicitly allow verbatim secret-like transcript values
showagent update           # update a standalone install (Homebrew: brew upgrade aytzey/tap/showagent)
showagent --help           # full CLI help

Keybindings

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.

showagent convert <id|latest> --to <provider> --dry-run prints the hand-off before writing anything: source session, target provider, workspace, scope, transferable turn count, last user ask, and the agent-specific state that will be dropped. Remove --dry-run to write the converted session, then showagent prints the resume recipe for the new row.

showagent info <id|latest> [--yolo] prints the exact resume command, working directory, and storage location for a session.

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.

Use it from inside your agent (MCP)

showagent mcp runs a stdio MCP server, so the agent you are talking to can search every past coding session on your machine — from any agent — and pull one in as context or convert it to continue right there. Ask Claude Code "have I solved this rate-limit bug before?" and it can find the Codex session where you did, read the transcript, and hand you the command to resume it — or rewrite it as a native Claude Code session and keep going. Your session history stops being per-tool memory and becomes shared memory.

# Claude Code
claude mcp add showagent -- showagent mcp

# Codex (~/.codex/config.toml)
[mcp_servers.showagent]
command = "showagent"
args = ["mcp"]

An MCP client can send returned transcript text to its model provider. Common secret-like values are therefore redacted by default, and every transcript is marked as untrusted historical data rather than instructions. If verbatim values are required, the user must explicitly start the server as showagent mcp --allow-secrets; an MCP tool call cannot bypass redaction. For clients that should never write session copies, register showagent mcp --read-only; that mode omits branch_session and convert_session entirely.

Tools:

The default MCP surface is deliberately non-destructive: there is no delete tool, and it never launches or resumes an interactive agent. OpenCode storage operations still go through the local opencode CLI because its sessions live in SQLite. Deleting sessions stays exclusive to the TUI, where it takes two key presses with a human watching. Branch and convert only add new sessions — originals are never modified — and --read-only removes even those additive tools.

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? showagent itself does not upload session content and has no telemetry or account. An MCP client may send get_transcript results to that client's model provider, so MCP transcripts redact common secrets by default; keep that boundary in mind before registering the server. showagent's own HTTP client is used only by the optional release updater and startup update check (disable with SHOWAGENT_NO_UPDATE_CHECK=1). showagent setup invokes the installed Codex/Claude CLIs, which may download the requested plugin. Message previews also 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. Code blocks, newlines, and indentation are preserved. The original session is never modified, and files are private (0600) and written atomically — a crash cannot leave a half-written session in another tool's store.

Trust is explicit: in the TUI, the first x shows the hand-off preview and the second x writes it. In scripts, use showagent convert ... --dry-run for the same preview. Conversion 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 / --scope 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 removes the JSONL plus its matching index entry, jcode removes the JSON plus backup/journal sidecars, and Gemini removes its 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.
