Checking when something was deployed

PostHog's CI writes a deploy marker into the project as an annotation every time a commit ships to an environment. These annotations are hidden_in_user_interface: true, so they don't show in the UI and are easy to forget — but they are the source of truth for "when did this go out". Always check them when staff ask about deploy timing, rather than inferring from when a metric or event volume changed (that conflates a capture change with a query/code change).

The deploy annotations

List them with posthog:annotations-list using {"search": "deploy"}. Each deploy marker looks like:

• content: Deployed PostHog/posthog@<sha> to <env> — env is prod-us, prod-eu, or dev
• creation_type: GIT
• scope: organization
• hidden_in_user_interface: true
• date_marker: the deploy time (UTC)

They're returned newest-first; paginate with offset if you need to go further back.
