Round-Trip Validation

Round-trip validation checks that a plugin remains usable after packaging metadata is read by each supported host.

Current checks

1. Run python tools/validate_repository.py to parse manifests, check marketplace paths, validate skills, and detect dead local Markdown links.
2. Run vally lint . for skill and evaluation structure.
3. Run dotnet test --solution agent-toolkit.slnx for .NET plugins and tests.

Results record

Record validation with:

• date and commit;
• host or command tested;
• plugin and version;
• expected discovery or runtime behavior;
• result and failure details;
• follow-up issue, if any.

Do not claim a host round trip was verified when only JSON parsing or local build validation was performed.
