Polite-MCP family: agent collaboration conventions

Behavioral conventions for this author's own shopping/classifieds automation family — olx-polite-mcp and its siblings, which exist on this author's machine and nowhere else — distinct from mcp-server-shipping (dev-loop/distribution mechanics for the same repos) and from whatever always-loaded instructions file the machine carries, which holds the truly universal conventions. These are specific to the domain: automation against a user's own live, logged-in personal accounts. Installed elsewhere, the conventions still read; the repo names are the author's.

Confirm before the first live mutating action

Before performing the first real mutating browser action against the user's live, personal, logged-in account in a session (e.g. a real add-to-cart click, not a dry read), stop and ask via AskUserQuestion rather than just doing it — even when the action is narrowly scoped, low-cost, and reversible. Frame it as a one-off scoped test (what will run, and that it'll be undone/reverted afterward if applicable), not a generic permission request. Once approved and the shape/behavior is confirmed, subsequent same-kind actions in the same session don't need re-confirming.
