- Around line 2665-2670: The code currently uses only the first segment
(firstSegment) when reporting a missing root argument, which loses the full SDL
path; change the error creation to pass the full configured argument path (e.g.,
the original slicing argument string or segments.join(".")/slicingArg) into
listSizeInvalidSlicingArgumentErrorMessage instead of firstSegment so the
diagnostic shows the full path; update the call site where argData is checked
(the block referencing segments, firstSegment, argData, errorMessages, and
listSizeInvalidSlicingArgumentErrorMessage) to supply the full path string and
ensure any helpers expecting just the name are adjusted to accept the dotted
path.

2669-2670: Gate dottedslicingArgumentson router support.These paths are now serialized into
costs.listSizesunchanged. If composition ships before router support, older routers can ignore them and start rejecting requests for fields that still require a slicing argument. Consider enforcing this with a compatibility check, feature gate, or rollout guard instead of relying on release ordering alone.Also applies to: 2758-2759

The new success cases only verify
costs.listSizes, so a regression in emitted composition output would still pass. Please mirror the earlier normalization checks with at least one assertion thatschemaToSortedNormalizedString(schema)preserves@listSize(slicingArguments: ["input.pagination.first"])—ideally also for the mixed flat+nested case.🤖 Prompt for AI Agents

Nitpick comments:
In `@composition/src/v1/normalization/normalization-factory.ts`:
- Around line 2669-2670: Paths are being unconditionally added to
listSizeConfig.slicingArguments and slicingArgChainByPath (slicingArgPath /
slicingArgChainByPath), which causes costs.listSizes to serialize slicing
arguments even when downstream routers may not support them; add a compatibility
gate before pushing/setting these values: detect router support (e.g., via a
feature flag or a runtime check like routerSupportsSlicingArgs(costs) or
enableRouterSlicingArgs) and only call
listSizeConfig.slicingArguments.push(slicingArgPath) and
slicingArgChainByPath.set(slicingArgPath, chain) when the gate returns true;
apply the same guarded change for the identical block around lines where slicing
arguments are added (the other occurrence at the reported range 2758-2759).
In `@composition/tests/v1/directives/listSize.test.ts`:
- Around line 655-676: Add assertions that verify the normalized SDL still emits
the `@listSize` directive with the nested slicingArguments: after the existing
checks in the "nested-path slicingArguments tests" (in the tests using
subgraphWithDeepNestedSlicingArg and subgraphWithMixedSlicingArgs /
ROUTER_COMPATIBILITY_VERSION_ONE), call schemaToSortedNormalizedString(schema)
on the returned schema and assert the string contains
'@listSize(slicingArguments: ["input.pagination.first"])' for the deep-nested
case and contains the corresponding combined form (e.g.
'@listSize(slicingArguments: ["limit","input.pagination.first"])') for the mixed
case; keep these assertions alongside the existing checks that reference
costs.listSizes.get('Query.search') so the test covers both runtime cost
normalization and the emitted normalized SDL.

When the list size comes from an argument nested in an input object,
use a dot-separated path in slicingArguments:
This PR contains composition changes for now. Composition passes slices argiments in the the same
fields, but this time it parses and validates the dot-path for each slicingArgument.
One small caveat. We should release this in the composition after the router has support for the same feature.
Otherwise, if a user composes config with dot-path slicingArguments and feeds to the router without support of it, then router will throw the error "400" for queries on fields having
requireOneSlicingArgument == true. It is because router will ignore such dot-path fields and validation won't pass.I will make a note on the documentation about these features requiring specific versions of composition and router.
