Fixes #673.

Summary

  • codex [OPTIONS] [PROMPT] — the interactive TUI with its optional initial prompt — was classified as a noninteractive command named after the prompt text: findForwardedCommand returned the first positional as { command }, and isCodexInteractiveTuiCommand only accepted the no-positional case. With runtime rotation enabled, the launch fell through the canonical-home branch into the disposable runtime shadow home.
  • The shadow mirror deliberately omits Codex's runtime SQLite state, so native Codex rebuilt the entire thread index from rollouts before submitting the prompt it already had in argv. Measured: ~52s on a 936-rollout store, scaling with session history, while stock Codex and the wrapper's bare TUI start instantly.
  • The same walk treated the token after -- as a command, though -- is precisely how a positional prompt is forced: codex -- exec is the prompt exec on codex-cli 0.148.0, not the exec subcommand.

What Changed

  • Classification follows the real root grammar. A positional is a command only when it resolves through a root-command allowlist mirroring codex --help — plus the hidden subcommands (responses-api-proxy, cloud-tasks, execpolicy, each documented by codex help <name>) and the e/a aliases, which now classify like their canonical commands (codex e --help skips the transport like exec --help always did). Anything else is the root prompt, and the launch takes the existing canonical-home app-helper branch (detachOnExit: true, useCanonicalHome: true) — the same split [bug] mcodex resume hangs with runtime rotation, and helper can prevent exit #647 established for resume/fork and [bug] codex-multi-auth-codex app-server cannot run on the shadow CODEX_HOME #659 for app-server. exec/review stay on the isolated shadow home.
  • The walkers mirror clap, verified against the binary. Every shape below was probed against native codex-cli 0.148.0 (non-TTY stdin distinguishes the TUI path from exec) to confirm the wrapper's classification matches native parsing:
    • -- forces the positional: everything after it is prompt, never a subcommand.
    • -i/--image <FILE>... is greedy — it consumes every free token up to the next option-like token. All four argv walkers skip the same span; without this, codex -i shot.png review would classify as review while native launches a TUI, and injected overrides could split a multi-image list mid-argv.
    • A filled prompt slot still lets the next free token match a subcommand (codex hello exec "echo hi" runs exec natively), so the scan continues past unknown positionals instead of settling on interactive.
  • Injected -c overrides stay on the option side of the prompt. The app-helper provider overrides and buildForwardArgs' cli_auth_credentials_store="file" used to be appended after the user argv; after a -- they would bind to the [PROMPT] positional as prompt text. insertArgsBeforeRootPrompt places them ahead of the first positional or -- for root launches. No-positional argv is byte-identical to the appended shape, and resume/fork/app/app-server keep their existing appended ordering.
  • Help beside a prompt skips the transport. codex "prompt" --help prints help and exits clean; the interactive branch detaches its helper on clean exits, so a helper started for a help print would idle until its detached timeout. Same reasoning and mechanism as the [bug] mcodex resume hangs with runtime rotation, and helper can prevent exit #647 request-command help skip; the scan stops at --, so help-looking prompt text still routes.

Validation

  • npx vitest run test/codex-bin-wrapper.test.ts --maxWorkers=1 — green apart from three pre-existing Windows-path resolver failures that fail identically on a clean main checkout on this macOS machine
  • npm run typecheck / npm run typecheck:scripts
  • npm run lint
  • npm test — same pre-existing macOS non-green set as reported with fix(codex): reap app helpers stranded by the detach grace #665 (Windows-path expectations, named-backup-export, install-codex-auth backup checks); each failing file reproduces byte-for-byte on clean main
  • Manual launch through the built wrapper with a positional prompt and rotation on: native Codex reached in ~2s on the canonical home, no runtime-shadow home created, no state_5.sqlite backfill, helper stopped cleanly on exit

New regression coverage in test/codex-bin-wrapper.test.ts (all verified failing without the scripts/codex.js change, for the canonical-home group):

  • canonical home for a TUI launch with a prompt after value-consuming options (-c, greedy -i, --cd) — asserts CODEX_HOME === ORIGINAL_CODEX_HOME, the pre-existing canonical state_5.sqlite is visible, provider overrides ride along, the prompt arrives verbatim as the final argument, and the canonical config.toml is never rewritten
  • canonical home for a ---forced prompt that spells a command name (codex -- exec), with the overrides landing on the option side of the --
  • canonical home for a prompt after a greedy multi-image option, with the image list kept contiguous
  • codex hello exec … classifies as exec (native retries the token after a filled prompt slot as a subcommand) and stays on the shadow home
  • the e alias stays on the shadow home like exec

Notes

  • The 2.8.6 tarball carries the same classifier, so upgrading alone does not address this.
  • Two residual edge divergences are known and deliberate: argv shapes native Codex hard-rejects anyway (an empty string inside an image span; two unknown positionals before a command) can classify differently, but the child exits 2 immediately either way — matching clap's rejection logic byte-for-byte did not seem worth the walker complexity. Happy to tighten if you disagree.

Greptile Summary

the pr updates codex root-argument classification so prompt-bearing tui launches use the canonical home while injected configuration remains before prompts and -- separators.

  • adds an explicit root-command and alias grammar for distinguishing prompts from subcommands
  • keeps runtime provider and file-auth overrides on the option side of positional input
  • adds vitest coverage for prompts, greedy image arguments, aliases, hidden commands, and separator handling
  • updates architecture and configuration documentation to describe the canonical-home flow

Confidence Score: 5/5

the pr appears safe to merge.

no blocking failure remains.

Context used:

…ome (ndycode#673)

The root grammar is `codex [OPTIONS] [PROMPT]` / `codex [OPTIONS] <COMMAND>
[ARGS]`, but findForwardedCommand read every first positional as a command, so
a TUI launch with an initial prompt was classified noninteractive and sent to
the runtime shadow home — whose mirror omits the runtime SQLite state, forcing
native Codex to rebuild the whole thread index from rollouts (~55s on a 936-
rollout store) before submitting the already-delivered prompt.

Classify a positional as a command only when it resolves through the root
command allowlist (visible commands, hidden subcommands, and the e/a aliases),
mirror clap for the rest of the grammar — `--` forces the positional, `-i/
--image` consumes free tokens greedily, and a filled prompt slot still lets a
later token match a subcommand — and keep scanning like native does. Prompt-
bearing launches now take the same canonical-home app-helper branch as the
bare TUI and resume/fork, with the wrapper's injected `-c` overrides (runtime
provider and cli_auth_credentials_store) inserted on the option side of the
prompt, where an append would have become prompt text after a `--`. A help
flag beside a root prompt skips the transport like the request-command help
forms, so printing help cannot strand a detached helper.

Every forwarded shape was probed against codex-cli 0.148.0 to confirm the
wrapper's classification matches native parsing, including `codex -- exec`
(the prompt "exec", not the exec subcommand) and `codex hello exec …` (native
runs exec).

📝 Walkthrough

severity: major correctness fix. prompt-bearing tui launches now remain on the canonical home instead of using the runtime shadow home and rebuilding thread indexes. no security or data-loss risk is identified. regression coverage exists in test/codex-bin-wrapper.test.ts for prompt classification, aliases, option parsing, routing, help handling, and argument ordering.

reviewers should focus on the root-command allowlist, shared positional-boundary logic, -- handling, greedy -i/--image parsing, later subcommands, and safe insertion of injected -c options in scripts/codex.js. the canonical-home decision is documented in docs/architecture.md, docs/configuration.md, docs/development/ARCHITECTURE.md, and docs/development/CONFIG_FLOW.md.

windows-specific argument and path behavior lacks explicit regression coverage. concurrency risks remain during runtime-home rotation and proxy shutdown. existing platform-specific failures remain unchanged.

Walkthrough

the wrapper now separates root prompts from launcher options. interactive tui launches retain the canonical CODEX_HOME, receive provider and auth overrides before prompts, and bypass runtime routing for help. tests and documentation cover these cases.

Learning: In ndycode/codex-multi-auth test files (e.g. `test/*.test.ts`), when creating V3 storage fixtures for accounts, it’s an intentional convention to use `as never` for deliberately minimal stored-account objects that only include `refreshToken`, `addedAt`, and `lastUsed`. Do not treat `as never` here as a type-safety problem: optional/other fields are expected to be populated by the runtime during execution, and the cast is used solely to keep the fixture minimal and consistent across existing tests.

Review round 1: `a` resolves to `apply` and skips the rotation transport like
the spelled-out command, and the hidden `execpolicy` subcommand stays a
command on the shadow-home fall-through rather than reading as a prompt.

ndycode and others added 2 commits August 21, 2026 05:58
This PR makes a `--`-forced prompt a first-class, tested shape, but four
launcher scanners predating it still walked the whole argv, so prompt text
could be read as flags and then rewritten in place:

- extractForcedAccountFlag stripped a `--account` out of the prompt and pinned
  the run from it. `codex -- --account 3 is wrong, fix it` reached Codex as
  "is wrong, fix it", silently pinned to an account nobody selected -- or hard
  failed with "--account 3 is out of range" for a launch that contained no
  flag at all.
- extractRequestedModel read `codex -- -m gpt-4 please fix this` as a request
  for gpt-4, which then coerced reasoning config for a model the user never
  asked for.
- replaceRequestedModel went further on the unsupported-model retry: it
  assigns nextArgs[i + 1] in place, rewriting the user's prompt from
  "-m gpt-4 please fix this" to "-m gpt-5.1 please fix this" before
  re-forwarding it.
- rewriteReasoningConfigArgs rewrote a `-c key=value` pair that was prompt
  text.

All four now stop at the first bare `--`, which is where native Codex stops
too: verified against codex-cli 0.147.0, where `codex -- completion` launches
the TUI with the prompt "completion" instead of running the completion
subcommand.

Also classify `stdio-to-uds` as the root subcommand it is. It is a real hidden
command in 0.147.0 (`codex stdio-to-uds --help` documents it) that was missing
from CODEX_ROOT_COMMANDS, so `codex stdio-to-uds <socket>` classified as an
interactive root prompt and took the app-helper branch with detachOnExit:
true. The relay exits in well under a second, so cleanup unref'd the helper
and left it plus its loopback proxy idling until the rotation idle timeout --
one leaked process per invocation. The allowlist comment now records how to
regenerate the list from clap's own completions, since a real command missing
from it is misrouted rather than merely misnamed.

Finally, two cleanups on the argv machinery this PR grew:

- findForwardedCommand, insertArgsBeforeRootPrompt and findForwardedSubcommand
  were three hand-copies of one walk, and insertArgsBeforeRootPrompt's comment
  conceded it had to walk "exactly like findForwardedCommand" with nothing
  enforcing it. A fix to the option-recognition rule applied to two of three
  would have injected `-c` overrides at a different offset than the classifier
  assumed. They now share findRootPositional, which reports the first
  positional, the `--` terminator, and the boundary where option-side content
  ends; each caller keeps its own documented policy for `--`, since the root
  grammar binds everything after it to [PROMPT] and a subcommand's does not.
- consumesNextArg rebuilt a 39-element Set for every argv token on every call,
  and the interactive branch re-ran the full classification it had just
  evaluated one line above. Hoist the Set; classify once.

…launches

The two user-facing docs were updated for ndycode#673, but the maintainer routing
reference still defined the branch this PR changed as "no forwarded subcommand
at all", and the ASCII diagram above it repeated the claim. A maintainer
reading either would conclude a prompt-bearing launch takes the shadow-home
branch and go debug the wrong transport.

Describe the branch as it now behaves -- bare `codex [OPTIONS]` and
`codex [OPTIONS] [PROMPT]`, including a prompt forced by `--`, with a first
positional that names no real root subcommand being that prompt -- and record
the two behaviors the PR adds to it: overrides injected ahead of the prompt
rather than appended, and the root-prompt help skip, where a help flag on a
launch that also carries a prompt forwards directly rather than starting a
helper that would idle until its detached timeout.

Review round 2: `hasCliAuthCredentialsStoreOverride` scanned past `--`, so a
forced prompt whose text spells `--config=cli_auth_credentials_store=...`
counted as a caller override and suppressed the file auth store the wrapper
depends on — prompt text acting as configuration.

Stopping that scan exposed the broader bug it had been masking: every
injection into subcommand argv was appended after any `--`, landing in the
subcommand's own positional list. Codex rejects that outright for `exec` and
`review` ("unexpected argument '-c' found"), and accepts it destructively
elsewhere — `codex sandbox -- echo hi` handed the injected pair to the
sandboxed command, and `codex mcp add t -- echo hi` wrote it into the server's
stored `args` in config.toml, a registration that stays corrupted. Both were
verified against codex-cli 0.148.0.

`insertArgsBeforeForwardedSeparator` now bounds the append at the separator
for subcommand argv, in `buildForwardArgs` and in the rotation helper's own
option injection. The subcommand token still leads, so `resume`/`fork` argv
ordering is unchanged, and argv without a `--` is byte-identical to before.

Taken, in 6e4dcc4 — the scan now stops at --.

Stopping it exposed the broader bug it had been masking: every injection into subcommand argv was appended after any --, landing in the subcommand's own positional list. exec/review reject that outright (error: unexpected argument '-c' found), so codex exec -- hi was already broken before this PR — but two other commands accept it destructively:

  • codex sandbox -- echo hi handed the injected pair to the sandboxed command; real codex printed hi -c cli_auth_credentials_store="file".
  • codex mcp add t -- echo hi wrote it into the server's stored args in config.toml — a registration that stays corrupted after the run.

Both verified against codex-cli 0.148.0 with a throwaway CODEX_HOME. So insertArgsBeforeForwardedSeparator now bounds the append at the separator for subcommand argv, in buildForwardArgs and in the rotation helper's own option injection (which had the same latent bug for resume/fork/app/app-server). The subcommand token still leads, so the #647 ordering assertions still pin what they mean, and argv without a -- is byte-identical to before.

On the suggested one-line diff: break alone is correct but not sufficient — on its own it converts the silent keyring case into a hard argv error for exec -- …, because it removes the suppression that was accidentally carving that shape out. The two changes need to land together.

Three regression tests: prompt text spelling the override no longer suppresses injection, exec -- "do the thing" places it before the separator, and resume --last -- "do it" covers the helper path. A note on the suggested test argv — -- -c cli_auth_credentials_store="keyring" is two tokens, which real codex rejects as surplus positionals regardless; the only runnable shape that tripped the old scan is a single --config=… token, so the test uses that.

Also rebased onto 7d8e183/efa3eef — thanks for the four scanner fixes, they're the same class of bug and my change sits alongside them. I kept indexOf("--") rather than routing through findRootPositional, with a comment saying why: that helper reports where the option side ends and stops at the first positional, so it answers exec for exec -- hi; the question here is only where the separator sits.

**/*.{js,ts,mjs,cjs}: Do not publish or replace a global codex binary; official OpenAI installation paths must retain ownership of the codex command.
Keep OAuth credentials local and restrict runtime rotation and local bridges to loopback interfaces.
Require hashed local client tokens to protect the optional loopback bridge.
Responses background: true compatibility must remain opt-in; requests using it must use stateful store=true routing rather than stateless store=false routing.
Never run npm install or update commands automatically; only display a manual upgrade notice when appropriate.
Experimental synchronization and backup flows must be non-destructive by default: preview before applying sync, preserve destination-only accounts, and fail safely on backup filename collisions.
Keep account storage project-scoped under the configured multi-auth root when operating in repo-specific workflows.

test/**/*.test.ts: Write Vitest test suites with globals enabled (describe, it, expect)
Maintain 80%+ coverage threshold across statements, branches, functions, and lines
Use removeWithRetry() for Windows filesystem cleanup instead of bare fs.rm to handle EBUSY, EPERM, and ENOTEMPTY errors
Do not rely on dist/ in tests; use source files instead
Do not skip tests without justification
Relax lint rules for test files as configured in eslint.config.js

⚙️ CodeRabbit configuration file

tests must stay deterministic and use vitest. demand regression cases that reproduce concurrency bugs, token refresh races, and windows filesystem behavior. reject changes that mock real secrets or skip assertions.

4760-4762: this new test also builds a dist/ fixture.

createRuntimeRotationProxyFixtureModule(fixtureRoot) at test/codex-bin-wrapper.test.ts:4762 writes and loads fixtureRoot/dist/lib/runtime-rotation-proxy.js. same root cause as the earlier finding on test/codex-bin-wrapper.test.ts:1296. route the new resume-path case through the same source-based seam once that seam lands.

as per coding guidelines, test/**/*.test.ts: "Do not rely on dist/ in tests; use source files instead."
