Based on recent review activity, included reviews refill at 4 per hour. 📝 WalkthroughWalkthroughThe pull request adds OpenAPI 2.0, 3.0, and 3.1 conversion to ADC. It adds document preparation, service and route generation, extension handling, SDK contracts, CLI wiring, output normalization, and integration coverage. ChangesOpenAPI conversion
Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🟡 Moderate · up to The converter can generate inconsistent service names when a root x-adc-name is used, which may produce incorrect output for affected OpenAPI documents; this should be fixed or explicitly accepted before merging.

68-101: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick winAdd a test for a slug that becomes empty.
Input that consists only of disallowed characters, for example
"/?", produces an empty string.slug_jointhen joins empty segments, and the converter can emit a name such as_or__. A test pins the current behavior and makes the downstream effect visible.🤖 Prompt for AI Agents

33-77: 🚀 Performance & Scalability | 🔵 Trivial | ⚖️ Poor tradeoffConsider a memoization cache or an expansion limit for repeated
$reftargets.
resolve_nodere-resolves every$reftarget from the frozen root each time it appears. Acyclic but fan-out reference graphs therefore expand exponentially. Example:#/a1refers twice to#/a2,#/a2refers twice to#/a3, and so on. Cycle detection does not stop this, because no pointer repeats on the stack. The recursion is also unbounded in depth, so a deeply nested document can overflow the stack.
prune_conversion_documentremovescomponents.schemas, which limits the practical surface. The remainingx-adc-*blobs andcomponents.pathItemsare still user-controlled. A cache keyed by pointer, or a node-count limit, keeps the resolution bounded.🤖 Prompt for AI Agents

Inline comments:
In `@rust/crates/adc-cli/src/pipeline.rs`:
- Around line 161-171: Update convert_openapi to validate each generated service
name before extending services, rejecting duplicates across input documents with
an error that includes both the current input path and duplicate service name.
Preserve successful conversion for unique names and fail before returning or
writing an ambiguous Configuration.
In `@rust/crates/adc-converter-openapi/src/lib.rs`:
- Around line 167-168: Update build_services so path_split_name and
op_split_name both derive from the same base string, honoring the root
x-adc-name consistently. In
rust/crates/adc-converter-openapi/src/lib.rs:167-168, adjust the path split
naming and corresponding operation split logic; in
rust/crates/adc-converter-openapi/tests/assets/basic-5.yaml:21-26, add a root
x-adc-name (or provide an equivalent extension fixture) covering both split
kinds.
- Around line 239-252: Update inline_path_prefix to remove the trailing slash
from the extracted path_prefix before concatenating it with route URIs, while
preserving the existing behavior for prefixes without a trailing slash.
In `@rust/crates/adc-converter-openapi/src/parser.rs`:
- Around line 50-54: Validate the parsed server URL’s host before constructing
the node in the parser flow; when host_str() returns None, return a ConvertError
instead of emitting a node with an empty host. Preserve the existing host, port,
and weight construction for URLs with a valid host.
- Around line 19-27: Remove the pre-substitution raw-URL parsing used to
initialize default_scheme, and derive the scheme from the substituted first
server URL within the idx == 0 branch of the server substitution loop. Preserve
the existing fallback when no first server URL exists and continue using the
parsed scheme for subsequent conversion.
In `@rust/crates/adc-converter-openapi/src/validate.rs`:
- Around line 32-34: Update the URL validation condition in validate.rs to
require the value to start with either “http://” or “https://”, matching the
existing error message; preserve the current ConvertError behavior for invalid
URLs.
- Around line 20-22: Update the info.title validation in validate.rs to require
a non-empty string, matching the behavior of validate_name, while preserving the
existing required/type error handling. Ensure empty titles are rejected before
build_main_service uses them as a fallback service name.
In `@rust/crates/adc-converter-openapi/tests/assets/basic-1.yaml`:
- Around line 1-6: Add a dedicated Swagger 2.0 fixture alongside the existing
OpenAPI assets, declaring swagger: "2.0" and including the Swagger 2.0 server
fields needed to exercise upgrade_swagger_2_servers. Keep the fixture minimal
and valid, with the existing httpbin.org metadata and paths structure preserved.
In `@rust/crates/adc-converter-openapi/tests/assets/extension-7.yaml`:
- Around line 6-9: Update the x-adc-route-defaults configuration so it does not
define an id inherited by generated routes; remove the id entry, or ensure each
generated route receives a distinct id before backend synchronization.
In `@rust/crates/adc-converter-openapi/tests/extension.rs`:
- Around line 39-42: Split case_2_empty_override_name_is_rejected into separate
tests and fixtures so the root-level empty x-adc-name and operation-level empty
x-adc-name are validated independently; ensure each test fails only when its
corresponding validation path accepts the empty name.
