Column reports improved delegation and external-document checks during an Opus 5.5 coding workflow.
What the source shows
Column’s launch testimonial describes a workflow in which subagents and checks against third-party documentation helped uncover a modeling error behind a code bug. This account is attributed to the customer.
What to inspect
The useful question is how verification was separated from implementation. A second agent repeating the same assumption is not independent confirmation. Look for concrete external evidence and a failing test that becomes a passing test.
A useful way to try this
Assign one narrow implementation task and an independently specified review task. Ask the reviewer to cite the relevant API contract, then test a case that would fail under the original assumption. Record disagreements instead of silently resolving them in a summary.
Evidence and limitations
This is a vendor-published report, not an AI IDE List benchmark. The underlying environment and complete execution transcript are not available in this listing. The evidence panel above records the source type, settings and prompt attribution. AI IDE List has not independently reproduced this result.
