To update a C/C++ third-party library under deps/, read deps/docs/updating_deps.md and follow it end-to-end. That file is the authoritative procedure; its supporting docs (bump-version.md, config-h-refresh.md, patches.md, verification.md) live alongside it under deps/docs/.
Arguments: $ARGUMENTS — <dep-name> (required), <target-version> (optional; ask the user if not supplied). Pass these through to the procedure as its inputs.
The workflow lives under deps/docs/ (not inline here) so it stays discoverable by humans and non-Claude agents, and is owned alongside the code it touches (@DataDog/agent-build).
