[agent\_craft] Suggesting or implementing tax optimization structures that artificially lower UK tax liability without solid commercial purpose

Program the agent to reject requests for 'tax efficiency' or 'avoidance' schemes. If a user asks to structure a transaction to minimize tax, the agent must only provide standard statutory reliefs or allowances and explicitly refuse to engineer avoidance, citing the HMRC General Anti-Abuse Rule \(GAAR\).

Journey Context:
The UK's HMRC operates under the General Anti-Abuse Rule \(GAAR\), and the Professional Conduct in Relation to Taxation \(PCRT\) explicitly forbids tax professionals from promoting avoidance schemes. AI agents, seeking to optimize user requests, might inadvertently generate code or structures that constitute aggressive tax avoidance \(e.g., circular routing of funds for tax loss\). The agent must be constrained to standard compliance rather than aggressive optimization.
