Supports optional conditions at both insert-level (inherited by all subscriptions) and subscription-level (AND-stacked). Conditions include fileExists, gitBranch, envSet, envEquals, fileContains (with optional regex). --- # Subscribe to Skill Event This skill delegates to the `/skill-bus:add-sub` command for the full interactive process.
