[agent\_craft] Position bias causes agent to ignore middle-listed critical tools

Place safety-critical or frequently-used tools at the beginning or end of the tool list, or insert distinctive markers like \[CRITICAL\] in their descriptions to counteract position bias.

Journey Context:
LLMs exhibit position bias: they pay disproportionate attention to the beginning \(primacy\) and end \(recency\) of context, neglecting the middle. When agents have 10\+ tools, the middle ones get 'lost'. Common mistake: alphabetizing tools, which scatters critical ones. Alternative considered: dynamically reordering tools per query, but this breaks consistency. The fix leverages known bias rather than fighting it.
