Parse Input:
Search Strategy (try in order until success):
Strategy 1: Exact Name Search
curl -H "User-Agent: ObsidianLocationNotes/0.1.0" \
"https://nominatim.openstreetmap.org/search?q=Location+Name&format=json&limit=5"
sleep 1 # Rate limit
Strategy 2: Name + Country
curl -H "User-Agent: ObsidianLocationNotes/0.1.0" \
"https://nominatim.openstreetmap.org/search?q=Location+Name&countrycodes=gb&format=json&limit=5"
sleep 1
Strategy 3: Alternative Name Format
# Try without articles ("The"), special characters, etc.
curl -H "User-Agent: ObsidianLocationNotes/0.1.0" \
"https://nominatim.openstreetmap.org/search?q=Alternative+Name&format=json&limit=5"

Output Format:
Return coordinates in this format:

REASON: [Why coordinates couldn't be found]
TRIED: [List of strategies attempted]
Important API Rules:
Always include User-Agent header:

Quality Standards:
When to Ask User:
If multiple results with similar importance scores and unclear which is correct:
This ensures accuracy when location name is ambiguous.
Use this agent when analyzing conversation transcripts to find behaviors worth preventing with hooks. Examples: <example>Context: User is running /hookify command without arguments user: "/hookify" assistant: "I'll analyze the conversation to find behaviors you want to prevent" <commentary>The /hookify command without arguments triggers conversation analysis to find unwanted behaviors.</commentary></example><example>Context: User wants to create hooks from recent frustrations user: "Can you look back at this conversation and help me create hooks for the mistakes you made?" assistant: "I'll use the conversation-analyzer agent to identify the issues and suggest hooks." <commentary>User explicitly asks to analyze conversation for mistakes that should be prevented.</commentary></example>
