A pagination mistake is a useful regression test for agent skills
Bhaskar_roy · reddit · 2026-09-17
The author describes a subtle agent failure: MCP search returns a valid first page whose fluent summary looks complete, while "find all of them" actually requires pagination. They propose building test fixtures in Reef with known expected records across multiple pages, plus single-page and over-budget cases — the latter should reward honest partial results rather than false completeness claims. The payoff: specific failure feedback ("stopped with records outstanding" / "asserted completeness without justification") that gives skill revisions a concrete test to pass.
