\u{1F4A1} Search Strategy:
ALWAYS search with index format FIRST to get an overview and identify relevant results.
This is critical for token efficiency - index format uses ~10x fewer tokens than full format.

Search workflow:
1. Initial search: Use default (index) format to see titles, dates, and sources
2. Review results: Identify which items are most relevant to your needs
3. Deep dive: Only then use format: "full" on specific items of interest
4. Narrow down: Use filters (type, dateRange, concepts, files) to refine results

Other tips:
\u2022 To search by concept: Use find_by_concept tool
\u2022 To browse by type: Use find_by_type with ["decision", "feature", etc.]
\u2022 To sort by date: Use orderBy: "date_desc" or "date_asc"`}function q(c,e){let s=c.title||`Observation #${c.id}`,r=new Date(c.created_at_epoch).toLocaleString(),t=c.type?`[${c.type}]`:"";return`${e+1}. ${t} ${s}
