Problem

I noticed that Datadog's UX copy was inconsistent across components, products, and teams. For example, button labels and error messages had mixed capitalization and inconsistent tone. Designers and engineers around the world contributed to it without a shared standard, resulting in a less polished, clear, and trustworthy product.

Copy guidelines existed, but designers rarely consulted them before writing a label. Since final copy lives in code, engineers often ended up making the last call on wording. I decided the fix needed to live in the codebase too.

Solution

GitHub PR showing Copyhound flagging a button label violation with a specific guideline reference

Flagging a button label that violates copy guidelines, inline in the PR review

I built an LLM-ready rule set that runs inside Datadog's existing PR review workflow via the ChatGPT Codex Connector. When a frontend PR includes copy changes, the bot automatically checks them against Datadog's copy guidelines — flagging violations inline with the specific rule broken and a suggested fix.

Every frontend PR at Datadog now gets an automated copy review before it ships. Since launch, the bot has surfaced copy feedback on over 2,000 PRs!
