## Summary
- restore source-specific wording across the `/import` picker, lifecycle
messages, diagnostics, and help text
- update the matching Unix and Windows snapshots
- leave import behavior unchanged
## Why
The import path currently supports one source, so the UI should identify
that source directly instead of presenting the flow as
provider-agnostic.
## Validation
- `just test -p codex-tui external_agent_config_migration` (12 passed)
- `just fix -p codex-tui`
- `just fmt`
## Why
External-agent import should be discoverable and deliberate without
blocking startup or claiming the public `codex [PROMPT]` CLI namespace.
The slash command keeps the flow local to the interactive TUI and reuses
the existing app-server import API.
## What changed
- add the user-facing `/import` slash command
- detect external-agent importable items only when the command is
invoked
- run imports through the embedded local app-server
- show start and completion messages, refresh configuration, and block
duplicate imports while one is pending
- reject the flow for unsupported remote and local-daemon sessions
## Validation
- `just test -p codex-tui external_agent_config_migration` (10 passed)
- manually exercised an isolated TUI fixture with existing
external-agent setup and session data using a fresh `CODEX_HOME`
- verified picker customization, plugin and session detection, import
completion, repeated invocation, and imported-session resume context
- the broader `just test -p codex-tui` run passed 2,805 tests, with 2
unrelated guardian feature-flag failures and 4 skipped tests
## Draft follow-ups
- review whether completion messaging should remain attached to the
initiating chat if the user switches chats during an import
- review shutdown semantics for an in-progress background import
## Stack
1. [#27064](https://github.com/openai/codex/pull/27064): remove the
startup migration flow
2. [#27065](https://github.com/openai/codex/pull/27065): extract the
picker renderer
3. [#27070](https://github.com/openai/codex/pull/27070): add the
external-agent import picker UX
4. [#27071](https://github.com/openai/codex/pull/27071): expose the flow
through `/import`
**This PR is stack item 4.** Draft while the lower stack dependencies
are reviewed.
## Why
Users need to understand what external-agent data Codex detected, what
is selected, and how to proceed before an import begins. The updated
picker makes focus, selection state, and the submission path explicit
while preserving the existing import backend.
## What changed
- replace the old migration prompt with a two-step external-agent import
picker
- add a customize view with explicit item focus, selection state,
counts, and a review action
- separate detected import data into a view model
- add Unix and Windows snapshots for prompt, item-focus, and
action-focus states
## Validation
- `just test -p codex-tui external_agent_config_migration` (10 passed)
- manually exercised an isolated TUI fixture covering customization,
selection toggles, review, import, repeated invocation, and session
resume
- the broader `just test -p codex-tui` run passed 2,805 tests, with 2
unrelated guardian feature-flag failures and 4 skipped tests
## Review note
This is the largest layer in the stack because the interaction state,
rendering changes, and required snapshots move together. It remains a
draft in case reviewers prefer a further presentation/state split.

**This PR is stack item 3.** Draft while the lower stack dependencies
are reviewed.
## Why
The external-agent import picker is easier to review when its rendering
refactor lands separately from new state and interaction behavior. This
layer is intended to be behavior-neutral.
## What changed
- extract external-agent migration rendering into a dedicated `render`
module
- preserve existing behavior while separating presentation from
interaction logic
- establish a smaller foundation for the import picker UX in the next PR
## Validation
- `just test -p codex-tui external_agent_config_migration` (10 passed)
