Summary

  • Both add-session writers (settings-daemon.py's /sessions/add and session-cli.sh's add) hardcoded remoteControl: true regardless of harness. For claude that's just a flag on the ordinary TUI, but for codex it replaces the process outright with the app-server pairing daemon (supervisor.sh) - so picking a codex profile from Add Session, or agent-box-session add --harness codex, always started the daemon and never a second interactive session.
  • Per lionello's answers on Login to Codex did not bootstrap a default/eponymous "codex" profile #623: a real codex profile should open the TUI, and the pairing daemon gets its own explicit entry instead of overloading a profile pick. Add Session now offers "codex remote control (pairing daemon, no profile)" as a pseudo-profile alongside shell; both writers default a codex session to the TUI unless that entry (or, from the CLI, a new --remote-control true flag, added for parity between the two writers) explicitly asks for the daemon.
  • ensure_harness_session (the auto-add right after install+login, Server/daemon mode belongs with the pseudo profiles, not as a profile field #504) now references the profile agent-box-profile seed (feat(profiles): a box arrives with profiles, and none of them is a default #508) already creates per installed harness, instead of always leaving profile: None - so a second codex session added afterwards from the picker has a profile to pick, which is the "prepopulate a default codex profile" half of lionello's second answer (already covered by feat(profiles): a box arrives with profiles, and none of them is a default #508's seed: HARNESS only, no MODEL/EFFORT/prompt, exactly "default model, default effort, no kick-off prompt").

Not touched: the deeper gap from the original triage comment - a box where codex is never added to installAgents (so AGENT_BOX_AGENTS/the seed step never sees it) still gets no session and no profile at all from a successful connect-card login, since the connect card offers codex regardless of installAgents. That's a real, separate design question (does a connect-only harness need a way into AGENT_BOX_AGENTS at all) and is left for its own issue/PR rather than folded in here.

Test plan

Native aarch64-linux checks (VM/interactive checks are x86-only and unavailable on this box):

  • nix run .#assemble (regenerated modules/agent-box.nix) + module-generated-up-to-date
  • assemble-module-escaping
  • backend-parity
  • one-spec-both-backends
  • golden-snapshot (updated via nix run .#update-golden, diff reviewed)
  • runtime-profile
  • profile-panel (42 tests, covers the picker and /sessions/add)
  • connect-card
  • session-route, sessions-registry
  • full native --keep-going set (all 32 aarch64-linux checks) - all green
  • python3 tests/test_agentbox.py (no --update needed; native fixture stubs profile binaries so this source-level change doesn't show up there)
  • bash -n modules/src/session-cli.sh, flake8 over the spliced settings-daemon payload with the same ignore list the writePython3Bin wrapper uses

Closes #623.

📝 Walkthrough

Walkthrough

Session creation now supports explicit remote-control modes. Codex defaults to its interactive TUI, while a new pseudo-profile starts the pairing daemon. Supervisor-created sessions reuse seeded harness profiles when available.

Changes

Remote control session handling

Layer / File(s) Summary
CLI remote-control option and persistence
modules/agent-box.nix, modules/src/session-cli.sh, tests/golden/vm/payloads/agent-box-session/bin/agent-box-session
The session CLI accepts only true or false, applies harness-specific defaults, and stores the resolved Boolean in session metadata.
Codex pairing-daemon selection
modules/agent-box.nix, modules/src/settings-daemon.py, tests/golden/web/payloads/agent-box-settings/bin/agent-box-settings
The profile picker adds a Codex pairing-daemon pseudo-profile. Codex uses remote control only for that option; ordinary Codex sessions use the interactive TUI.
Automatic harness profile reuse
modules/agent-box.nix, modules/src/settings-daemon.py, tests/golden/web/payloads/agent-box-settings/bin/agent-box-settings
Supervisor-created sessions use a harness-named profile when its profile file exists. Otherwise, the profile remains unset.

Codex sessions declared through NixOS module session options can still start the pairing daemon by default instead of the interactive TUI. Align this seeded-session path with the new Codex default, while preserving explicit remote-control configuration, before merging.

Explanation

The changes provide a seeded Codex profile and explicit pairing-daemon options. However, the linked issue requires the post-login Codex session to start the pairing daemon automatically, while the described default behavior starts the TUI. The context does not show that the automatic post-login session still explicitly enables remote control.

Resolution

Ensure the automatic Codex session created after install and login explicitly uses remote-control mode and starts the pairing daemon, while preserving TUI defaults for ordinary Codex sessions. Add a test that verifies this post-login behavior.

…#623)

Both writers of a codex session (settings-daemon.py's /sessions/add and
session-cli.sh's `add`) hardcoded remoteControl: true regardless of harness.
For codex that is not a flag on the ordinary TUI, as it is for claude -- it
replaces the process outright with the app-server pairing daemon
(supervisor.sh) -- so picking a codex profile from Add Session, or running
`agent-box-session add --harness codex`, always opened the daemon and never
a second interactive session.

Per lionello's answers on #623: a real codex profile should open the TUI,
and the daemon gets its own explicit entry instead. Add-session now offers
"codex remote control (pairing daemon, no profile)" as a pseudo-profile
alongside `shell`, and both writers default codex sessions to the TUI
unless that daemon is explicitly requested (a new --remote-control flag on
the CLI side, for parity).

ensure_harness_session (the auto-add after install+login, #504) now also
references the profile agent-box-profile seed (#508) already creates per
installed harness, instead of always leaving profile: None -- so a second
codex session added afterwards has a profile to pick.

Checks run (aarch64-linux, native): assemble-module-escaping,
backend-parity, connect-card, golden-snapshot, module-generated-up-to-date,
one-spec-both-backends, profile-panel, runtime-profile, session-route,
sessions-registry, plus the full native --keep-going set.

CodeRabbit flagged that seedSessions still hardcoded remoteControl=true
for sessionOpts/userOpts, so a codex session declared through
users.<name>.sessions or the legacy options started the pairing daemon
while CLI- and web-created codex sessions already defaulted to the TUI
(issue #623). Derive the effective harness (session agent, falling back
to the user's) and default remoteControl to false only for codex,
mirroring bin/agentbox's sessionsSeedFile resolution and the CLI/web
defaults from the rest of this PR.

addressed in 2d43018: seedSessions now derives the effective harness and defaults codex to remoteControl=false when unset, mirroring the CLI/web default

Rebased onto master (805c1ff) and addressed the CodeRabbit finding: seedSessions now derives the effective harness and defaults remoteControl=false for a NixOS-seeded codex session left unset, matching the CLI/web default from the rest of this PR (sessionOpts.remoteControl / userOpts.remoteControl in modules/agent-box.nix.in).

Also picked up an in-flight, uncommitted fix already staged in this checkout for the same finding and folded it in rather than redoing the work.

Full native check set (nix build -L --keep-going .#ci-native) and python3 tests/test_agentbox.py pass locally; pushed as 2d43018. CI is running now.

All CI is green (module/VM, native checks, all 4 VM lanes, AWS/Azure template validation, CodeRabbit) and the PR is mergeable/clean against master. No new findings from CodeRabbit's re-review. Ready for you to merge whenever you'd like.
