In `@src/types/tools.ts`:
- Around line 80-82: Track explicitly declared bare tool names separately from
namespace-derived aliases, and use that set for the “default” fallback checks in
the tool declaration logic. Update src/types/tools.ts lines 80-82 and
src/server/responses-undeclared-tool-guard.ts lines 324-326 so a declaration of
only foo__view_image cannot authorize default.view_image or { namespace:
"default", name: "view_image" }. Add regressions covering both request forms.
In `@tests/responses/responses-undeclared-tool-guard.test.ts`:
- Line 445: Add parallel fixtures in the undeclared-tool guard tests for the
`item.namespace === "default"` path, using `namespace: "default"` with bare
`name: "view_image"`. Cover acceptance, dotted-versus-flattened declaration
precedence, and rejection when no bare tool is declared, while preserving the
existing raw-name cases and targeting the authorization logic in
`normalizeDeclaredToolName`.

Reviewed exact head 5de903b. The bridge change is useful, but the native Responses change relaxes the guard without completing the tool-identity normalization.
In src/server/responses-undeclared-tool-guard.ts, a matched default namespace now returns undefined; createUndeclaredToolCallGuardBlockRewrite then returns the original block unchanged. The added dotted-name test explicitly expects that unchanged upstream block too. Thus a request declaring only bare view_image can receive name=default.view_image, or namespace=default with name=view_image, even though the client did not declare that identity. Avoiding OCX's error is not proof that the client's tool dispatcher can execute the call. This is the same guard's documented reason for not passing undeclared top-level identities verbatim.
Please normalize the downstream identity on the affected Responses relay path, or keep that path fail-closed and scope this PR explicitly to the bridge until a supported caller contract proves otherwise. Tests need to observe the client-visible added/done/terminal items, call_id/id and arguments (plus JSON/non-stream output where this guard is used), not merely absence of OCX's error. Add an explicit namespace-field fixture: the current new fixtures only cover dotted names.
Keep the declared dotted/flattened identities and undeclared-bare negative controls. There is no requirement to expand to arbitrary namespaces or default__ fallback in this PR. Document the supported normalization boundary and update the shared helper's code-mode-only comment. Full exact-head CI remains required; no local product code was executed for this review.
… track bare provenance
- Downstream identity normalization in Responses relay: rewrite provider-invented
default. prefix or namespace: "default" back to declared bare tool for SSE streams
(added, done, terminal completed/incomplete snapshots) and non-streaming JSON
responses, preserving all item fields (id, call_id, arguments).
- Bare tool provenance tracking: collectDeclaredBareWireToolNames collects top-level
and builtin functions namespace declarations that do not carry . or __, preventing
declarations like foo__view_image from authorizing default.view_image or
{ namespace: "default", name: "view_image" }.
- Shared normalization helper: update normalizeDeclaredToolName and guard helper
docstrings to clarify default namespace normalization boundary beyond code-mode
exec helpers.
- Test coverage in tests/responses/responses-undeclared-tool-guard.test.ts covering
bare wire collection, SSE stream item rewriting, terminal snapshot rewriting, JSON
rewriting, negative controls for declared namespaced tools, and preservation of
explicitly declared default. and default__ tools.

Rechecked b3bcdb4. The Responses path now does more than admit the invented name: the added/done and completed/incomplete rewrites, non-stream JSON rewrite, and normalization before rememberPassthroughResponse address the client-visible identity issue from my previous review. The separately collected bare declarations also make the intended negative control explicit rather than relying only on a general alias set.
Remaining acceptance evidence should exercise the real relay and continuation caller: one request declaring a bare tool, an upstream default-prefixed tool call, and a second turn returning its result should observe the same normalized identity/call_id in downstream output and replay. The helper-level SSE/JSON fixtures are useful but do not alone prove the new core wiring and replay state agree. Preserve explicitly declared namespaces and the unrelated-namespace negative controls.
At this head I see metadata/hygiene checks, not a successful exact-head product suite/typecheck run. Please supply the caller regression and required readiness checks before merge. No local product/provider execution or merge was performed in this review.
