One blocking correctness issue remains on the current head.
The shared catalog nudge now treats any advertised tool named exec (or its transformed wire name) as Codex code mode. That classification is too broad. OpenCodex's existing Cursor code-mode predicate requires a visible freeform exec and no visible bare shell bridge; the shared helper discards the freeform metadata and infers the V8-isolate/ALL_TOOLS contract from the name alone.
That means a normal structured tool named exec, or a mixed catalog containing exec plus exec_command/shell_command, can receive incorrect system guidance saying that exec is JavaScript evaluated in a V8 isolate and that nested helpers should be used through tools.*. This can make routed models send the wrong arguments or avoid a legitimate top-level execution tool.
Please determine code mode from the original OcxTool objects before reducing them to wire names, ideally by sharing the existing semantic predicate. At minimum require a visible freeform exec and exclude the flat shell-bridge case, then pass the verified advertised wire name into the formatting helper.
Please also add focused regressions for:
{ name: "exec", freeform: false }-> generic guidance, not code-mode guidance;- freeform
execplus a visibleexec_command/shell_command-> no nested-only code-mode classification; - transformed freeform
execsuch ascx_exec-> still receives the intended code-mode guidance.
The two earlier CodeRabbit findings about transformed cx_exec naming and separately advertised apply_patch are fixed on this head, and the rest of the PR looks focused and sound. Upstream CI should also run successfully on the final exact head before merge.

One merged, four carried, and one plan decision reversed. #1900 landed with its three gates verified in the diff first - HTTPS-only non-loopback discovery, the Bearer refused before any plain-HTTP request builder, and a clean EOF with open tool calls emitting a typed error rather than done. The reversal is #1887. The plan had it closed as superseded by #1896; it holds the catalog-aware guard that decides the bridge from what the request actually advertised, where #1896 hardcodes the names off a boolean. Closing it would have re-introduced the defect #1895 exists to remove. Also recording the process correction that held: WP6 faulted me for merging #1902 before its CI could be judged, and #1900 was merged three minutes after its run reported success rather than eight minutes before.

The simulation reproduced exactly; my explanation of it did not. I wrote that lidge-jun#1887 conflicts only because lidge-jun#1896 exists, naming the shared native-exec files. In the sequence I actually ran, lidge-jun#1896 had not been merged yet. Isolating it: lidge-jun#1887 alone is clean, and so is each of lidge-jun#1900, lidge-jun#1895 and lidge-jun#1896 paired with it - the conflict needs lidge-jun#1900 and lidge-jun#1895 together, and it lands in tool-definitions.ts, which is not a native-exec file and has nothing to do with lidge-jun#1896. I presented dropping lidge-jun#1887 as evidence-driven when the evidence pointed elsewhere. The more serious one: closing lidge-jun#1887 as superseded would have deleted a guard this plan calls critical. lidge-jun#1896's codeModeBridgeGuidance hardcodes exec and the mcp_opencodex-responses names on a boolean; lidge-jun#1887 derives them from the advertised catalog and returns none when exec is not advertised. That is the plan's own no-hardcoded-exec matrix row, and it is the exact defect lidge-jun#1895 exists to remove - so making lidge-jun#1896 canonical without migrating would re-introduce it one PR after deleting it. Five items are now listed as migration prerequisites. Also corrected: the scope comparison is a wash rather than a win for lidge-jun#1896, and lidge-jun#1903 is a 32-file cross-cutting change rather than a rebase-and-merge item.
Three PRs landed and four are held, each for a reason that belongs to the PR rather than to my schedule. The part worth keeping is the defect I introduced. #1951 fixed #1895's blocker by deciding code mode from freeform metadata rather than the name exec, but my port of the shell-bridge predicate dropped the Cursor original's !tool.namespace requirement - so a namespaced MCP exec_command cancelled code mode on a genuine code-mode turn and silently stripped the guidance. It failed safe, generic rather than false guidance, which is precisely why nothing caught it and why an audit that runs the predicate against adversarial catalogs beats one that reads it. #1953 fixes it, driven red first, and a second reviewer then failed to break the classifier across ten catalog shapes.

Summary
Routed Codex code-mode sessions were told the valid tool names were exactly the flat top-level catalog. That made Grok, Claude, Gemini, Kiro, and Command Code skip live nested helpers such as
tools.codex_app__list_threadsandtools.codex_app__send_message_to_thread.The helpers were never missing. Codex installs them on
tools.<name>and keeps deferred metadata on the isolate globalALL_TOOLS, nottools.ALL_TOOLS. OpenCodex already leavessupports_search_tool: trueso those helpers stay out ofexec.description. The shared catalog nudge then contradicted that contract by listing only top-level names.This change keeps the top-level contract and, when
execis listed (including a wire-renamedcx_exec), teaches the isolate nested-helper path. Cursor guidance gets the same isolate-global discovery sentence. It does not dump deferred tools intoexec.descriptionand does not flipsupports_search_tool.Verification
