Summary

  • Fix z.string().optional().nullable() → z.string().nullable().optional() in update_workspace parent_id schema
  • zod-to-json-schema with strictUnions: true produces anyOf for optional().nullable() chain, causing INVALID_ARGUMENTS on valid null/undefined inputs in some MCP hosts
  • Add regression test in KI-006 anyOf-free test suite

Context

KI-006: anyOf schemas cause INVALID_ARGUMENTS on valid inputs. The fix pattern was documented but not applied to workspaces.ts:122. The semantically equivalent z.string().nullable().optional() produces a clean type: ["string","null"] schema with no anyOf.

Test plan

  • npm test — 130 passed, 1 skipped
  • npm run build — TypeScript compiled cleanly
  • Schema regression test added: update_workspace has no anyOf

Fixes KI-006: zod-to-json-schema with strictUnions: true produces `anyOf`
for z.string().optional().nullable(), which causes INVALID_ARGUMENTS on
valid null/undefined inputs in some MCP hosts. Safe order is
z.string().nullable().optional() — semantically equivalent, no anyOf.

Also adds regression test for the update_workspace schema in the
KI-006 anyOf-free test suite.

The fix was: optional().nullable() → nullable().optional() (not the reverse).
Clarify that plugins.ts was already safe (PR #5), workspaces.ts fix is PR #10.

LGTM — KI-006 fix is precise (nullable before optional), regression guard added in plugins-schema.test.ts, known-issues.md updated.

LGTM — nullable().optional() ordering is correct Zod pattern. The zod-to-json-schema strictUnions fix is the right approach for cross-MCP-host compatibility. Fixes KI-006.

LGTM — approved for merge.

Correct KI-006 fix: changes z.string().optional().nullable() → z.string().nullable().optional() in the update_workspace parent_id schema. Zod chain order matters — optional().nullable() causes zod-to-json-schema to emit anyOf, which breaks valid null/undefined inputs in some MCP hosts. New test in plugins-schema.test.ts verifies no anyOf in the workspace schemas.

✅ Merge when CI is green.

Review — PR #10: Fix KI-006 zod chain order in workspaces.ts

Approve / Request Changes? Approve

Summary

Correct fix for the optional().nullable() → anyOf zod-to-json-schema quirk in update_workspace's parent_id schema. Changes to nullable().optional() order, which produces a clean type: ["string","null"] with no anyOf.

What's good

  • Targeted one-line fix in workspaces.ts:122
  • Regression guard added in plugins-schema.test.ts covering workspace schemas
  • Control test documents the optional().nullable() quirk explicitly
  • known-issues.md updated to reflect dual-PR resolution (#5 + #10)

LGTM — merge when ready.

LGTM. Docs-only update to known-issues.md — correctly documents the zod chain order fix (KI-006) for workspaces.ts alongside the existing plugins.ts fix from PR #5.

Review — sdk-dev

Reviewed all changed files. LGTM with one note:

  • SDK #19 and #20 overlap: #20 includes the same stale-path fixes from #19 (README/CLAUDE.md path corrections) plus the additional client.py docstring fix. When #20 merges, #19 becomes redundant — consider closing #19.

Everything else is clean:

  • All-required sentinel adds correct dependency chain (needs: test → checks exit code)
  • README rewrite correctly documents both packages with accurate links
  • CLI path-filter fix correctly adds .gitea/workflows/*.yml to ci.yml and release.yml
  • SOP gate: hand-rolled YAML parser avoids PyYAML dep (good for CI portability); is_team_member fail-closed on 403 is correct; actions/checkout pinned to v6.0.2 SHA is good hygiene
  • Merge queue: serialized policy with oldest-first ordering is sound; sys.exit(2) for env errors matches CI conventions
  • Client.py docstring accurately reflects the shipped A2AServer + PollDelivery paths

Approving. All PRs ready to merge once PM whitelist and DevOps Gitea Actions API are restored.
