Anthropic's own docs say don't use Cowork for regulated workloads — the same week legal became its top user group

Three releases landed the week of May 12 that are worth reading together as a set: Aderant launched Agent Center at Momentum Global: Collections, Appeals, and Talent Evaluation agents for law firm billing workflows, with humans in the loop for approvals. Anthropic released 20+ connectors and 12 practice-area plugins for Claude Cowork, with legal professionals now outpacing developers as the top user group by a factor of three. And buried in Anthropic's own support documentation: **Cowork activity is not captured in audit logs, the Compliance API, or data exports.** Their guidance is explicit — **don't use it for regulated workloads.** Same week, Honeycomb shipped Agent Timeline — purpose-built observability for multi-agent workflows, every LLM call and tool invocation in a single coherent view. I wrote a longer piece on what this means for engineering teams building in regulated environments and what to actually do about it before shipping agents into production.

Fair point. The piece is specifically about operational workflows: billing, collections, matter management, and appeals. That distinction should have been clearer up front.
