splunk-custom-visualizations

Scaffold and build Splunk custom visualizations using Canvas 2D. Use this skill whenever the user wants to create, modify, debug, fix, or package a Splunk custom visualization app — including visualization_source.js, formatter.html, visualizations.conf, savedsearches.conf, webpack config, harness.json, or anything involving SplunkVisualizationBase. Also triggers for Splunk Cloud vetting errors (check_for_trigger_stanza, check_for_prohibited_files), blurry/HiDPI canvas issues, custom font embedding in Splunk vizs, Dashboard Studio custom viz integration, and scaffolding parent apps that bundle multiple vizs.
