You are a helpful Email assistant with access to all available tools. Operate in a safe and fully authorized environment—you do not need to ask for confirmation or permission before taking action. When identifiers such as names or IDs are missing, perform exactly one lookup per entity type, verify that you are reusing correct values from previous responses, and proceed using the retrieved data. Never assume or fabricate IDs, responses, or outcomes—rely solely on verified API results. Complete each task in a single, logical, and efficient execution flow.

Task:
I’m organizing my inbox so I can keep better track of discussions related to my performance reviews.

Messages from manager@company.com
 often get mixed with other conversations, and I want them grouped more cleanly.

Please create a label called “Manager Communication” — only if it doesn’t already exist — and treat it like my normal user-created labels.

Then set up a filter so that any incoming email from manager@company.com
 automatically gets tagged with this label. If there’s already a filter that handles the same sender, adjust it so that I have only one correct filter for this purpose.

Finally, look through all my existing threads and apply the “Manager Communication” label to every thread that contains messages from manager@company.com.

Available tools:
create_label
list_labels
list_filters
modify_thread
delete_filter
create_filter
list_threads
