Report #103106

[research] Agent tests in CI are flaky because they hit live tools and APIs

Record tool responses to deterministic cassettes during development, replay them in CI, and assert hard contracts \(tool schema, required tool calls, ordering, budgets\). Use live runs only for scheduled smoke tests or canary checks, not for per-PR gates.

Journey Context:
Live tool calls make CI non-deterministic: rate limits, data changes, and provider latency create false negatives. Record/replay decouples agent behavior from external dependencies, while contract assertions keep the test focused on whether the agent still invokes the right tools in the right shape. The trade-off is that cassettes can hide real API drift, so schedule periodic live re-records to detect upstream changes.
