Judicial Review

PR introduces skills namespace APIs and removes the Worker surface from the public client; overall change is cohesive but includes a breaking API removal and a new potential sensitive-data exposure path via parameter stringification.

Findings: 0 critical, 2 warnings, 0 info

API Contracts

⚠️ WARNING in src/Casedev/ICasedevClient.cs:57

Public Worker service is removed from the client interface, which is a breaking API change for existing consumers in a minor release.

Recommendation: Either retain a deprecated Worker surface (shim to new endpoints if applicable) or bump the major version and document the breaking change explicitly.

Security

⚠️ WARNING in src/Casedev/Models/Agent/Skills/Namespaces/NamespacePublishParams.cs:106

ToString() serializes RawBodyData, which includes skill file contents; if this string is logged or surfaced in errors, it can leak sensitive code or client data.

Recommendation: Redact or omit files[].content (and potentially files) in ToString/FriendlyJsonPrinter, or provide a safe debug representation that does not include file payloads.

DB Cooper Database Review

No database schema, migrations, or query changes appear in this release PR; changes are client SDK models/tests and service wiring, so DB risk is minimal.

No database risks found. Migrations and DB-impacting changes look safe.

Oppenheimer Cleanup Review

Repo-wide scans for worker APIs and auto-shutdown references returned zero matches beyond unrelated V1 services, so no additional safe deletions or collapses were proven from this diff. The changes look like a straightforward API surface update and removal of worker endpoints with no remaining references found.

No cleanup opportunities found. This code is already lean.
