Function lookupBoundTask

internal/app/hook.go:124–143

lookupBoundTask returns the task whose session_id matches $CLAUDE_CODE_SESSION_ID, or nil if no such task exists, the env var is unset, or the DB lookup fails. Hook code must never fail loud — a hook error blocks the user's session — so all errors are swallowed and treated as "unbound".

// lookupBoundTaskSlug returns the slug of the bound task, or "" if the
