   - **```code-checks with cms.weekN.PR_hash/tool-conf-version```**: In case an external update is needed to run code-checks (e.g. due to interface changes in header files) then first run PR tests for cmsdist/external which should deploy externals on CVMFS. Then request the code-checks with the newly deployed externals tools configuration e.g. `code-checks with cms.week0_PR_01234567/47.0-cms2` (external tools configuration is available via cmsdist PR summary page).
