A2A Contract Lab v0.1.0

A2A Contract Lab v0.1.0

An offline-first A2A 1.0 interoperability and contract testing CLI.

Included

• focused Agent Card semantic validation
• bounded HTTP+JSON transport with explicit deadlines
• nine non-destructive contract scenarios
• built-in loopback mock agent for reproducible offline testing
• terminal, stable JSON, JUnit XML, and self-contained HTML reports
• zero runtime dependencies and no API key requirement

Verification

• 54 tests passed
• Ruff passed
• strict mypy passed across nine source files
• complete demo: 9 passed, 0 failed, 0 skipped
• wheel and source distribution built successfully

The project targets the A2A 1.0 wire version and canonical v1.0.1 data model.
It is an independent contract harness, not an official conformance
certification.
