load_codex_cli_credential copied tokens.account_id straight into CodexCliCredential.account_id with no type check. A Codex auth file whose account_id is JSON null therefore propagated None into CodexChatModel._account_id, and model_post_init raised TypeError: 'NoneType' object is not subscriptable on the account prefix in its log line. A numeric or boolean account_id slipped through the same way, reaching the ChatGPT-Account-ID header as a non-string.
Treat any non-string account_id as absent and fall back to the credential's empty-string default, matching how a missing account_id already behaves.
`_extract_claude_code_credential` copied `expiresAt` straight into
`ClaudeCodeCredential.expires_at`, so a credentials file whose `expiresAt` is a
string, null, list or object reached `is_expired` and raised
`TypeError: '<=' not supported between instances of 'str' and 'int'`. That
aborted the whole lookup instead of skipping the malformed source and moving on
down the documented order, the way the rest of the loader already behaves for a
malformed `claudeAiOauth` container.
Validate the field the way the sibling branches validate their input: log a
debug line and skip the source so the next candidate is tried.
load_codex_cli_credential called .get on the parsed ~/.codex/auth.json
(and $CODEX_AUTH_PATH) without checking that the top level is an object.
_load_json_file returns any valid JSON value, so an array or scalar payload
raised AttributeError out of CodexChatModel.model_post_init instead of the
documented 'Codex CLI credential not found' error. Guard the top level the
same way the sibling Claude loader and its own nested tokens guard do.
* fix(models): reuse the Claude Code OAuth token read from a file descriptor
ClaudeChatModel accepts a Claude Code OAuth token through
CLAUDE_CODE_OAUTH_TOKEN_FILE_DESCRIPTOR, but that handoff can be drained
only once: a pipe returns EOF after the first read and a file descriptor
keeps its advanced offset. _read_secret_from_file_descriptor read it again
on every call and kept nothing. Every ClaudeChatModel instance loads
credentials in model_post_init, and create_chat_model builds fresh
instances per run, so with a descriptor-only handoff the first model
authenticated and every model after it -- including the title model of
the very first run -- had no credential. The Anthropic SDK then raised
"Could not resolve authentication method" before sending a request.
A secret read from a descriptor is now kept for the life of the process,
keyed by (env_var, fd), so a different descriptor is still read fresh.
The read happens under a lock so two threads building their first model
concurrently cannot race one of them to EOF. Empty reads and OSError are
not cached and behave as before; lookup order, config keys, and log
messages are unchanged.
* docs(changelog): reference #5411 in the Claude Code OAuth descriptor fix entry
* test(models): pin that a closed descriptor handoff keeps its token
Review follow-up on #5411: the descriptor secret cache is keyed on the
fd number, which the OS recycles. Folding os.fstat identity into the key
would break the property the cache exists for -- once the handoff fd is
closed after the first read, fstat raises EBADF and every later model
would lose the token again -- and it would still miss a regular file
rewritten in place, which keeps its st_dev/st_ino.
The handoff is fixed at process start, so keep the number as the key and
state the invariant instead: a closed handoff keeps serving its token, a
secret placed on a recycled number is not re-read, and anything handing
over a new secret in-process must clear the cache. A new test pins the
closed-handoff behavior; an fstat-fingerprinted key fails exactly that
test.

* feat: add Claude Code OAuth and Codex CLI providers
Port of bytedance/deer-flow#1136 from @solanian's feat/cli-oauth-providers branch.\n\nCarries the feature forward on top of current main without the original CLA-blocked commit metadata, while preserving attribution in the commit message for review.
* fix: harden CLI credential loading
Align Codex auth loading with the current ~/.codex/auth.json shape, make Docker credential mounts directory-based to avoid broken file binds on hosts without exported credential files, and add focused loader tests.
* refactor: tighten codex auth typing
Replace the temporary Any return type in CodexChatModel._load_codex_auth with the concrete CodexCliCredential type after the credential loader was stabilized.
* fix: load Claude Code OAuth from Keychain
Match Claude Code's macOS storage strategy more closely by checking the Keychain-backed credentials store before falling back to ~/.claude/.credentials.json. Keep explicit file overrides and add focused tests for the Keychain path.
* fix: require explicit Claude OAuth handoff
* style: format thread hooks reasoning request
* docs: document CLI-backed auth providers
* fix: address provider review feedback
* fix: harden provider edge cases
* Fix deferred tools, Codex message normalization, and local sandbox paths
* chore: narrow PR scope to OAuth providers
* chore: remove unrelated frontend changes
* chore: reapply OAuth branch frontend scope cleanup
* fix: preserve upload guards with reasoning effort wiring
