457 sites carried an upstream prefix into every surface a user reaches — shell
exports, docs, CI, the SDK. CODEX_ is not our name and it was never going to
stop arriving on its own: it is what upstream writes, and every sync brings more.
Two namespaces, because they answer different questions.
DEV_* the app's own configuration — DEV_HOME, DEV_PROFILE, the rest
HANZO_API_KEY a credential for the Hanzo stack, which is not app config
CODEX_API_KEY held the literal string "CODEX_API_KEY", so the rename moves the
value and not just the constant. It becomes HANZO_API_KEY, which is what
create_hanzo_provider already reads through HANZO_MACHINE_ENV_KEYS — one name
for one credential instead of two spellings of it.
vendor/ is untouched, which is the point of vendor/: upstream code keeps
upstream names, and the boundary is a path rather than a habit.
The docs read as OpenAI's Codex CLI: a getting-started page titled for it,
`codex --enable skills` and `code sandbox macos` for commands that do not
exist, defaults given as gpt-5.1-codex-max/openai when they are
zen5-coder/hanzo, a Homebrew page describing a formula we do not publish.
Removed three tui-stream-chunking notes and the execpolicy page: they
document modules and a subcommand that live only in the vendored upstream
copy. There is no execpolicy subcommand and no .codexpolicy loader in
code-rs; the page told users to run something the binary does not have.
Rewrote tui-alternate-screen against the source. It described an
auto/always/never enum and a --no-alt-screen flag; the shipped behavior is a
tui.alternate_screen bool with Ctrl+T, which replays the transcript into
scrollback on the way out — a better answer to Zellij than the one written
down. Genuine openai-provider documentation stays.
Three regressions the merge introduced, all caught by building and running:
- `core/src/model_provider_info.rs` — upstream added `auth`,
`experimental_bearer_token` and `websocket_connect_timeout_ms` to
ModelProviderInfo; the Hanzo provider now sets them (None: our bearer comes
from HANZO_USER_KEY, not a command, and the websocket default is fine).
This was the only compile error in 7004 changed files.
- `core/src/config.rs` — the default provider fallback had reverted to
"openai". Back to HANZO_PROVIDER_ID. This one is the whole product.
- `cli/src/main.rs` — the entire clap identity had reverted: `--help` printed
"Codex CLI" and `Usage: code`. Restored name/bin_name = "dev", the about
line, subcommand help, and the doctor/preview/login hints (17 sites).
- `tui/src/updates.rs` — the in-product upgrade hint had reverted to
`npm install -g @just-every/code@latest`, which would send our users to
someone else's package.
`core/tests/hanzo_identity.rs` needed one call-site update for upstream's new
`built_in_model_providers(Option<String>)` signature; it then caught nothing
further, which is the point of it.

Our history is just-every's with author emails rewritten, so the graphs are
disjoint and git finds no merge base. Supplied one by hand: d1f1f51a41, the
just-every commit matching our Oct-2025 fork point (22 files apart). 9618
upstream commits, 7004 files, +1.81M/-159k, 37 conflicts.
Resolution:
- Upstream code where our side was the Oct-2025 prototype of a feature they
have since reimplemented 3-5x larger (agent_runs, browser_sessions,
history_cell/{agent,browser}, the vt100 harness and its snapshots).
- Upstream's config.rs module split (builder/defaults/sources/validation)
kept; zen5-coder and the provider-follows-model rule re-applied on top.
- Ours where the file IS the identity: README, package.json, postinstall,
release notes pipeline, integration-zed.
- Hybrid where upstream improved a file we had branded: updates.rs (their
release-repo migration, our hanzoai/dev), release.yml (their fail-fast npm
auth check, our package name), chatwidget.rs (their turn handling, our
HANZO_USER_KEY hint), exec human output (their 237 lines, our banner).
Superseded and dropped deliberately: our resume_command_name() coder-alias
hack — upstream's derive_resume_command_name() reads the invocation basename
generically, which yields "dev" for us.
LLM.md now records the real topology and the sync point; AGENTS.md and
CLAUDE.md are symlinks to it again. Single parent on purpose: adopting
jecode/main as a second parent would re-import 13,742 commits carrying the
upstream author emails a prior rewrite deliberately removed.
Version 0.2.188 -> 0.2.189.

Apparently we were not running our `pnpm run prettier` check in CI, so
many files that were covered by the existing Prettier check were not
well-formatted.
This updates CI and formats the files.
This PR adds oauth login support to streamable http servers when
`experimental_use_rmcp_client` is enabled.
This PR is large but represents the minimal amount of work required for
this to work. To keep this PR smaller, login can only be done with
`codex mcp login` and `codex mcp logout` but it doesn't appear in `/mcp`
or `codex mcp list` yet. Fingers crossed that this is the last large MCP
PR and that subsequent PRs can be smaller.
Under the hood, credentials are stored using platform credential
managers using the [keyring crate](https://crates.io/crates/keyring).
When the keyring isn't available, it falls back to storing credentials
in `CODEX_HOME/.credentials.json` which is consistent with how other
coding agents handle authentication.
I tested this on macOS, Windows, WSL (ubuntu), and Linux. I wasn't able
to test the dbus store on linux but did verify that the fallback works.
One quirk is that if you have credentials, during development, every
build will have its own ad-hoc binary so the keyring won't recognize the
reader as being the same as the write so it may ask for the user's
password. I may add an override to disable this or allow
users/enterprises to opt-out of the keyring storage if it causes issues.

- core/agent_tool: recognize "cloud" model and append prompt positionally; honor per‑mode args
- core/codex(agent_run): include "cloud" in command resolution + PATH check
- core/slash_commands: default /plan,/solve models now include "cloud"; test asserts prompt includes it
- core/agent_defaults: add cloud case (no default flags); unit test ensures empty defaults
- docs: note default agent set includes "cloud"; add config example
Build passes via ./build-fast.sh. Full test suite currently fails on unrelated preexisting test drift (protocol/test-support imports, enum shapes).
### Title
## otel
Codex can emit [OpenTelemetry](https://opentelemetry.io/) **log events**
that
describe each run: outbound API requests, streamed responses, user
input,
tool-approval decisions, and the result of every tool invocation. Export
is
**disabled by default** so local runs remain self-contained. Opt in by
adding an
`[otel]` table and choosing an exporter.
```toml
[otel]
environment = "staging" # defaults to "dev"
exporter = "none" # defaults to "none"; set to otlp-http or otlp-grpc to send events
log_user_prompt = false # defaults to false; redact prompt text unless explicitly enabled
```
Codex tags every exported event with `service.name = "codex-cli"`, the
CLI
version, and an `env` attribute so downstream collectors can distinguish
dev/staging/prod traffic. Only telemetry produced inside the
`codex_otel`
crate—the events listed below—is forwarded to the exporter.
### Event catalog
Every event shares a common set of metadata fields: `event.timestamp`,
`conversation.id`, `app.version`, `auth_mode` (when available),
`user.account_id` (when available), `terminal.type`, `model`, and
`slug`.
With OTEL enabled Codex emits the following event types (in addition to
the
metadata above):
- `codex.api_request`
- `cf_ray` (optional)
- `attempt`
- `duration_ms`
- `http.response.status_code` (optional)
- `error.message` (failures)
- `codex.sse_event`
- `event.kind`
- `duration_ms`
- `error.message` (failures)
- `input_token_count` (completion only)
- `output_token_count` (completion only)
- `cached_token_count` (completion only, optional)
- `reasoning_token_count` (completion only, optional)
- `tool_token_count` (completion only)
- `codex.user_prompt`
- `prompt_length`
- `prompt` (redacted unless `log_user_prompt = true`)
- `codex.tool_decision`
- `tool_name`
- `call_id`
- `decision` (`approved`, `approved_for_session`, `denied`, or `abort`)
- `source` (`config` or `user`)
- `codex.tool_result`
- `tool_name`
- `call_id`
- `arguments`
- `duration_ms` (execution time for the tool)
- `success` (`"true"` or `"false"`)
- `output`
### Choosing an exporter
Set `otel.exporter` to control where events go:
- `none` – leaves instrumentation active but skips exporting. This is
the
default.
- `otlp-http` – posts OTLP log records to an OTLP/HTTP collector.
Specify the
endpoint, protocol, and headers your collector expects:
```toml
[otel]
exporter = { otlp-http = {
endpoint = "https://otel.example.com/v1/logs",
protocol = "binary",
headers = { "x-otlp-api-key" = "${OTLP_TOKEN}" }
}}
```
- `otlp-grpc` – streams OTLP log records over gRPC. Provide the endpoint
and any
metadata headers:
```toml
[otel]
exporter = { otlp-grpc = {
endpoint = "https://otel.example.com:4317",
headers = { "x-otlp-meta" = "abc123" }
}}
```
If the exporter is `none` nothing is written anywhere; otherwise you
must run or point to your
own collector. All exporters run on a background batch worker that is
flushed on
shutdown.
If you build Codex from source the OTEL crate is still behind an `otel`
feature
flag; the official prebuilt binaries ship with the feature enabled. When
the
feature is disabled the telemetry hooks become no-ops so the CLI
continues to
function without the extra dependencies.

- Adopt upstream in common/file-search and add TUI popup/types
- Preserve fork invariants in core (browser/agent/web_fetch gating, UA/version)
- Keep our TUI and CLI flows; resolve conflicts per policy
- Protocol: align mcp_protocol to upstream; add TS for Verbosity
- file-search: provide run_streaming shim to satisfy TUI usage
- common: make sandbox summary robust to new fields
Verification:
- scripts/upstream-merge/verify.sh: PASS (build-fast + API checks)
This PR does the following:
* Adds the ability to paste or type an API key.
* Removes the `preferred_auth_method` config option. The last login
method is always persisted in auth.json, so this isn't needed.
* If OPENAI_API_KEY env variable is defined, the value is used to
prepopulate the new UI. The env variable is otherwise ignored by the
CLI.
* Adds a new MCP server entry point "login_api_key" so we can implement
this same API key behavior for the VS Code extension.

* Clarify how the shell's handling of quotes affects the interpretation
of TOML values in `--config`/`-c`
* Provide examples of the right way to pass complex TOML values
* The previous explanation incorrectly demonstrated how to pass TOML
values to `--config`/`-c` (misunderstanding how the shell’s handling of
quotes affects things) and would result in invalid invocations of
`codex`.
Seeing timeouts on certain, slow mcp server starting up when codex is
invoked. Before this change, the timeout was a hard-coded 10s. Need the
ability to define arbitrary timeouts on a per-server basis.
## Summary of changes
- Add startup_timeout_ms to McpServerConfig with 10s default when unset
- Use per-server timeout for initialize and tools/list
- Introduce ManagedClient to store client and timeout; rename
LIST_TOOLS_TIMEOUT to DEFAULT_STARTUP_TIMEOUT
- Update docs to document startup_timeout_ms with example and options
table

When item ids are sent to Responses API it will load them from the
database ignoring the provided values. This adds extra latency.
Not having the mode to store requests also allows us to simplify the
code.
## Breaking change
The `disable_response_storage` configuration option is removed.
- Resolve upstream delete of user_agent.rs; use default_client::get_codex_user_agent
- Switch client construction to default_client with originator header
- Update AuthManager::shared and CodexAuth::from_codex_home call sites to pass originator
- Fix openai_tools shell tool description formatting and include writable roots
- Deduplicate/repair config_types derives; import Serialize/Display early
- Use rollout::policy::is_persisted_response_item and remove dead import
- Keep our TUI architecture intact; no functional UI changes
Build: ./build-fast.sh passes with zero warnings
3 quick fixes to docs/config.md
- Fix the reference table so option lists render correctly
- Corrected the default `stream_max_retries` to 5 (Old: 10)
- Update example approval_policy to untrusted (Old: unless-allow-listed)
This PR cleans up the monolithic README by breaking it into a set
navigable pages under docs/ (install, getting started, configuration,
authentication, sandboxing and approvals, platform details, FAQ, ZDR,
contributing, license). The top‑level README is now more concise and
intuitive, (with corrected screenshots).
It also consolidates overlapping content from codex-rs/README.md into
the top‑level docs and updates links accordingly. The codex-rs README
remains in place for now as a pointer and for continuity.
Finally, added an extensive config reference table at the bottom of
docs/config.md.
