Why

Automation consumers need CTS release ordering and eligibility fields that the legacy transport summary omits. Raw fetch output can contain human progress UI, so consumers must not parse it as provider data.

Change

  • Adds adt cts tr metadata <transport> --json: exactly one JSON document on stdout.
  • Adds matching cts_transport_metadata MCP tool.
  • Projects typed SAP request/task fields: number, parent, owner, description, status, type, and last-change timestamp.
  • No manual XML parser or consumer-specific SAP endpoint.

Verification

  • Focused command test: pass.
  • CLI/MCP parity: 17 tests pass.
  • MCP integration: 92 tests pass.
  • OpenSpec strict validation: pass.
  • Repository typecheck remains blocked by existing unrelated ADK/CDS baseline errors; no diagnostics reference this change.

Summary by CodeRabbit

  • New Features
    • Added a CTS transport metadata command with JSON output for requests and tasks.
    • Added the cts_transport_metadata MCP tool with matching results.
    • Metadata includes number, status, type, parent, owner, description, and last-change timestamp.
    • JSON output is cleanly written to stdout, while diagnostics are sent to stderr.
  • Bug Fixes
    • Improved transport and task matching when retrieving metadata.

Review Summary

This PR successfully adds a typed CTS transport metadata API for automation consumers. The implementation is well-structured with clear separation of concerns:

Key Strengths:

  • Clean architecture with proper separation between CLI command, service layer, and client
  • Dependency injection pattern enables comprehensive testing
  • Error handling properly propagates errors with appropriate exit codes
  • Consistent API design across CLI and MCP tools
  • Good test coverage with focused unit tests

Implementation Quality:

  • The validation logic correctly handles empty transport identifiers after trimming
  • Type definitions are properly structured with optional fields
  • The service layer correctly maps between different field name conventions (SAP vs. normalized)
  • Both request and task metadata handling is correctly implemented with proper parent relationships

The changes are focused, well-tested, and ready for merge. All tests pass according to the PR description, and the implementation provides the automation-safe boundary needed by CI consumers.

Review Change Stack

📝 Walkthrough

Walkthrough

Adds a typed CTS transport metadata service and exposes it through a JSON CLI command and an MCP tool. The ADT client preserves request and task metadata, including parent and last-change fields. CLI and MCP parity tests cover requests and tasks.

Changes

CTS transport metadata

Layer / File(s) Summary
Metadata contract and typed projection
openspec/changes/add-cts-transport-metadata-json/..., packages/adt-client/src/services/transports.ts, packages/adt-cli/src/lib/services/cts/..., packages/adt-cli/src/index.ts
Defines the typed metadata projection. The ADT client selects matching requests or tasks and maps parent, description, type, owner, status, and last-change metadata.
CLI metadata command
packages/adt-cli/src/lib/commands/cts/tr/metadata.ts, packages/adt-cli/src/lib/commands/cts/tr/index.ts, packages/adt-cli/src/lib/commands/cts/tr/metadata.test.ts
Adds cts tr metadata <transport>, JSON and formatted output, stderr error reporting, non-zero failure status, command registration, and focused tests.
MCP metadata tool
packages/adt-mcp/src/lib/tools/cts-transport-metadata.ts, packages/adt-mcp/src/lib/tools/index.ts, packages/adt-mcp/tests/integration.test.ts
Adds and registers cts_transport_metadata. The tool resolves the shared client, returns JSON metadata, and reports errors through MCP responses.
CLI and MCP parity validation
packages/adt-cli/tests/e2e/parity.cts.test.ts, openspec/changes/add-cts-transport-metadata-json/specs/cts-transport-metadata/spec.md, openspec/changes/add-cts-transport-metadata-json/tasks.md
Validates equivalent request and task results from CLI and MCP and records the feature requirements and verification tasks.

Estimated code review effort: 3 (Moderate) | ~30 minutes

Merge Risk: 🟡 Moderate · up to fdbda

The new CLI and MCP metadata endpoints can return the parent transport when a task is requested, causing automation to consume incorrect CTS metadata; field mapping also relies on non-canonical aliases. Merge should wait until requested-unit selection and canonical field decoding are corrected.

SAP returns the parent request and the requested task as siblings when
fetching a task (e.g. GET .../DEVK900002 yields root.request=DEVK900001
and root.task=DEVK900002). The previous lookup picked unwrapped.request
first, so the metadata CLI/MCP returned the parent request number, kind,
and fields instead of the task's.

Prefer the unit whose number matches the requested trkorr before falling
back to request/task/raw payload. Adds a parity test that fetches a task
through both CLI and MCP and asserts the task unit is projected.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Select the requested transport unit before adapter output.

When SAP returns a parent request and its tasks as siblings, CtsTransportMetadataService.get() builds the parent unit first and appends task units without matching requestedTransport. Lines 37-41 serialize that result unchanged. A task query can therefore project its parent instead of the requested task.

Select the unit whose number equals requestedTransport in CtsTransportMetadataService. Add task assertions for both CLI and MCP output.

Use the canonical CTS response type for decoding.

transportrequests.get() returns the typed TransportResponse, whose root.request and root.task arrays define fields such as number, owner, desc, status, type, and lastchanged_timestamp. The service instead casts the response and each unit to Record<string, unknown> and reads undeclared aliases such as trkorr, as4text, and as4user. Use the exported CTS response type for selection and metadata mapping.
