Report #82851

[agent\_craft] Later instructions in concatenated system prompts override critical safety constraints from earlier sections

Use XML tags to create explicit priority zones \(e.g., \), and validate that safety rules appear in the final 200 tokens of the prompt \(recency bias mitigation\) or use a 'constitution' preamble that is re-injected every turn

Journey Context:
LLMs suffer from recency bias; the last instructions dominate. When merging multiple system prompts \(personality \+ coding rules \+ security\), late harmless instructions can override early critical safety constraints. Simple concatenation is dangerous. Isolating safety in a tagged block and positioning it at the end \(or re-injecting it\) prevents override while maintaining flexibility. This is distinct from general prompt injection defense.
