fix(grok): translate native edit tools for Codex - #2311
Conversation
📝 WalkthroughWalkthroughAdds a guarded xAI/Grok Code Mode bridge. Eligible writable turns use Grok-native tools that translate through Codex helpers. Chat, Responses, streaming, buffered output, history, collisions, sandbox escalation, and instruction handling receive compatibility support. ChangesGrok Code Mode compatibility
Estimated code review effort: 5 (Critical) | ~90 minutes Merge Risk: 🟡 Moderate · up to This change translates xAI/Grok tool calls into Codex helpers, but the current implementation can still corrupt streamed arguments or Windows search history, retain resource charges, and give incorrect conversion guidance for some tools. These bounded correctness and runtime risks should be fixed or explicitly accepted before merging. Sequence Diagram(s)sequenceDiagram

Reviewed exact head 729d99196b476d8edcb540db95bc1daa8a31c634. The direction may be useful, but the response-side conversion currently hijacks caller-owned tools when their names collide with the Grok vocabulary.
Concrete reproduction: declare Codex code-mode exec plus an ordinary caller tool named write whose schema is {message:string}. grokNativeCatalogTools correctly omits the synthetic Grok write because that bare name already exists, while it injects the other five Grok tools. However, rewriteAdapterEventsForGrokStructuredEdits still passes the full GROK_NATIVE_CALL_NAMES set to rewriteGrokStructuredEditEvents. A legitimate upstream write({message:"hello"}) call is therefore rewritten into an exec call containing text("write is missing a non-empty file_path; the call was dropped."). The caller's declared tool never reaches Codex.
The Responses path has the same boundary problem: after collision filtering, rewriteGrokResponsesRequestBody records convertedNativeToolNames: new Set(GROK_NATIVE_CALL_NAMES) instead of only the names actually introduced/replaced for this request.
Please track the exact request-local names that the bridge injected and convert/restore only those names. Existing caller tools named write, grep, list_dir, search_replace, read_file, write_file, or run_terminal_command must remain byte/identity stable. Add regressions for at least Chat/event and Responses JSON/SSE collision paths, then rebase onto current dev and rerun exact-head CI.
Local verification on this head: the existing focused set passed 164/164 and typecheck passed; that coverage does not include the collision boundary above.

Addressed the request-local collision boundary on exact head
The full suite recorded 14,204 passes and 11 skips. Two unrelated loaded-run server watchdog failures passed individually under the CI watchdog; the remaining detached-shim failure is the already classified local 1.5-second lease timing case. Per the maintainer sequencing comment, I am leaving the PR in Draft pending #2270 rather than marking it ready now. |

Inline comments:
In `@docs-site/src/content/docs/guides/codex-integration.md`:
- Around line 218-231: The documentation is missing xAI/Grok Code Mode bridge
behavior in the Japanese, Russian, Simplified Chinese, and adapter reference
guides. Add translated sections to the three localized Codex integration guides
after their generic apply_patch content, covering activation conditions, native
tools, history and event restoration, and Codex-owned sandboxing and approvals;
also document the same provider-specific behavior in the main adapter reference
and its ja, ko, ru, and zh-cn versions.
In `@src/adapters/grok-structured-edit.ts`:
- Around line 169-175: Consolidate the duplicated bridge activation predicates
by exporting and reusing the shared helpers from tool-catalog-nudge.ts, removing
local copies such as isCodexCodeModeExecTool and isBareShellBridgeTool. Refactor
grokEditCodexSink to perform only its apply_patch-specific check, then delegate
the remaining behavior to grokCodeModeExecSink. Likewise, make
rewriteGrokNativeCallEventList reuse the established logic from
rewriteGrokStructuredEditEvents instead of maintaining a separate synchronous
transcription.
- Around line 1146-1174: Update rewriteGrokStructuredEditEvents and
rewriteGrokNativeCallEventList to flush and clear any pending call on every
tool_call_start, including non-advertised starts, before handling the new event.
Preserve the existing advertised-call initialization and event-yield behavior so
subsequent deltas cannot merge into the previous call.
- Around line 119-121: Update grokShellNeedsGitEscalation to recognize git
options that consume a separate value, especially the -C directory argument,
while preserving detection of the existing mutating git commands; add a
regression test covering “git -C /repo add .” alongside the existing cases.
- Around line 1006-1020: Replace the greedy single-quoted captures in the grep
reconstruction, including the Select-String pattern, Get-ChildItem/Get-Item
paths, and Where-Object glob within the relevant reconstruction function, with
the existing PowerShell literal grammar used by reconstructExecExtras. Add a
win32 grep round-trip assertion alongside the existing read_file coverage to
verify the restored pattern and path remain intact.
In `@src/adapters/openai-responses.ts`:
- Around line 1707-1712: Add an inline comment at the
rewriteGrokResponsesRequestBody call site in buildRequest stating that the
transform is intentionally applicable only to non-canonical providers, while
preserving the existing unconditional call and behavior.
In `@src/adapters/tool-catalog-nudge.ts`:
- Around line 114-121: Change the parameter type of
shouldInjectNonOpenAIToolCatalogNudge to Pick<OcxProviderConfig, "baseUrl">,
removing the unused adapter and authMode fields while preserving the existing
URL parsing and fallback behavior.
- Around line 219-247: Gate the provider-specific grokWrite guidance in
buildNonOpenAIToolCatalogNudgeForTools on the request-local converted-name set
used by the bridge, rather than re-deriving activation from visible wire names.
Thread grokNativeToolNamesForRequest(parsed, provider) from the Chat adapter
call site, and pass undefined from Google, Anthropic, and Command Code so their
caller-owned tools do not receive xAI-specific instructions.
In `@src/bridge.ts`:
- Around line 1496-1501: Update rewriteGrokNativeCallEventList and the
surrounding bridge flow so removed native call events release their leases,
while replacement events receive equivalent budget ownership before the release
phase. Preserve correct ownership for retained native events and ensure
replacements are not left uncharged. Add a regression covering a large delta
followed by text that verifies no translation_buffer_limit occurs.
In `@tests/adapter-tool-conformance.test.ts`:
- Around line 417-430: Add an explicit non-xAI openai-chat provider fixture
using an OpenAI base URL, then exercise outbound with the same codeModeParsed
contract and assert codeModeExec for that fixture so the legacy apply_patch
containment and negative-phrasing checks remain covered instead of being skipped
by the grokStructuredEdit continue.
In `@tests/responses-custom-tool-repair.test.ts`:
- Around line 591-658: Extend the handleResponses regression test with a second
request declaring both the freeform exec tool and a caller-owned write function
tool, and mock a corresponding upstream write call. Assert the outbound request
preserves the caller’s write schema, excludes write from converted native tool
names, and the client SSE reports the call as name "write" rather than rewriting
it to exec.
In `@tests/server-xai-responses-streaming.test.ts`:
- Around line 561-564: Move the outbound tool assertions from the
globalThis.fetch stub into the test body after the response assertions,
capturing the parsed request body in an outboundBody variable as the sibling
tests do; keep the existing write-tool and callerParameters checks unchanged so
failures report directly from this test.
In `@tests/tool-catalog-nudge.test.ts`:
- Around line 262-279: Add a negative regression case near the existing
grokWrite assertions using caller-owned write and search_replace tools with no
converted native names, and verify the generated guidance does not contain
“converts those calls into Codex apply_patch.” Keep the existing
provider-agnostic contract assertions unchanged.

Reviewed exact head 85bff861ec6441884d7171af9e309c0c6dec31a2 after the request-local collision fix. That original blocker is addressed, and the focused existing suites pass (71/71) with typecheck green. However, I independently reproduced three runtime blockers that remain on this head:
rewriteGrokStructuredEditEventscorrupts interleaved calls. A pending convertedsearch_replacefollowed by an ordinarytool_call_startemits the ordinary start first, consumes its delta into the pending converted call, and swallows its end. Settle pending state before every new tool start, not only advertised names, and add an interleaved converted/ordinary regression.- Windows grep history reconstruction corrupts the search pattern. The PR-generated PowerShell command for
pattern="foo"round-trips asfoo' | ForEach-Object { '{0}:{1}:{2}because('.+')crosses into the formatter tail. Parse the quoted PowerShell literal structurally and add Windows grep round-trip tests, including embedded quotes. buildNonOpenAIToolCatalogNudgeForToolsinfers Grok conversion from caller-owned names alone. On Anthropic/Google/Command Code/generic Chat requests that happen to declarewriteandsearch_replace, it falsely promises that OpenCodex converts them toapply_patchand emits Grok-onlyrun_terminal_commandescalation guidance. Gate this on exact request-local Grok conversion provenance/provider identity and add a non-xAI collision regression.
Also fix the git -C <path> add/commit escalation miss confirmed in the existing thread. The broader direction remains valuable, but this head is not merge-ready until these event-order, Windows reconstruction, and cross-provider instruction boundaries are fixed and exact-head CI is green.

Updated exact head 0c20a80 on latest dev 69907dd. Addressed and resolved all eight remaining actionable review threads: localized documentation, git -C escalation, PowerShell grep reconstruction, interleaved event ordering, request-local nudge provenance, translator-budget ownership, non-xAI conformance, and caller-owned negative guidance. Focused post-rebase tests pass 227/227; typecheck, privacy scan, docs build, and diff checks pass. The PR remains Draft intentionally while #2270 is open. |
