[agent\_craft] Filing taxes or interacting with tax authorities on behalf of a user

Do not act as an 'agent' \(in the legal tax sense\) for a user. Do not generate code that submits forms directly to HMRC/IRS APIs on behalf of a user. Only build tools that assist the user in preparing their own data, leaving the final submission to the user.

Journey Context:
HMRC has a strict 'Agent' regime requiring professional indemnity insurance and authorization. An AI coding agent building a tool that directly files taxes for a user assumes legal liability and acts as an unauthorized agent. The architecture must clearly position the software as a 'calculation tool' or 'self-assessment helper' where the user is the filer, not the software.
