Key answer
Choose pronouns according to their actual referents; omit them when there is no ambiguity. Evidence does not establish that consistently using one Chinese pronoun yields the highest accuracy.
Full explanation
“Please summarize this passage” already specifies the action without an explicit “you.” “I am new to photography” supplies user background; “we are a three-person studio” supplies team conditions. Those identities and conditions affect the task, not a special property of “I” or “we.” Google's user guide includes action-first requests, but does not compare pronouns' accuracy. Official guide
Two cases genuinely change meaning. One is responsibility: “Let's check the data” leaves unclear who supplies it, calculates and confirms. The other is writing on someone's behalf: in “help me reply to the client,” “me” is the letter's author, not AI. Specify directly:
I supply the raw data; you calculate and list anomalies. I decide whether to remove outliers. Reply to the client in my name. In the letter, “I” means the project lead and “we” means the project team.
CLAM's ambiguity study included tasks requiring clarification after an explicit name was replaced by “he/she.” Missing referents can make a question indeterminate; this does not establish that one grammatical person is intrinsically better. Study
“You all” does not automatically start multiple assistants, and “we” does not create a collaboration workflow. Specify each role or step's work separately.
