Topic-Specific Documentation Search

Use when: User asks about specific feature/component/concept

Speed: ⚡ Fastest (10-15s) Token usage: 🟢 Minimal Accuracy: 🎯 Highly targeted

Trigger Patterns

"How do I use [FEATURE] in [LIBRARY]?"
"[LIBRARY] [COMPONENT] documentation"
"Implement [FEATURE] with [LIBRARY]"
"[LIBRARY] [CONCEPT] guide"

Workflow (Script-First)

# STEP 1: Execute detect-topic.js script
node scripts/detect-topic.js "<user query>"
# Returns: {"topic": "X", "library": "Y", "isTopicSpecific": true}

# STEP 2: Execute fetch-docs.js script (handles URL construction automatically)
node scripts/fetch-docs.js "<user query>"
# Script constructs: context7.com/{library}/llms.txt?topic={topic}
# Script handles fallback if topic URL fails
# Returns: llms.txt content with 1-5 URLs

# STEP 3: Process results based on URL count
# - 1-3 URLs: Read directly with WebFetch tool
# - 4-5 URLs: Deploy 2-3 Explorer agents in parallel

# STEP 4: Present findings
# Focus on specific feature: installation, usage, examples

Examples

shadcn date picker:

# Execute script (automatic URL construction)
node scripts/detect-topic.js "How do I use date picker in shadcn?"
# {"topic": "date", "library": "shadcn/ui", "isTopicSpecific": true}

node scripts/fetch-docs.js "How do I use date picker in shadcn?"
# Script fetches: context7.com/shadcn-ui/ui/llms.txt?topic=date
# Returns: 2-3 date-specific URLs

# Read URLs directly with WebFetch
# Present date picker documentation

Next.js caching:

# Execute scripts (no manual URL needed)
node scripts/detect-topic.js "Next.js caching strategies"
# {"topic": "cache", "library": "next.js", "isTopicSpecific": true}

node scripts/fetch-docs.js "Next.js caching strategies"
# Script fetches: context7.com/vercel/next.js/llms.txt?topic=cache
# Returns: 3-4 URLs

# Process URLs via 2 Explorer agents
# Present caching strategies

Benefits

✅ 10x faster than full docs ✅ No filtering needed ✅ Minimal context load ✅ Best user experience

Fallback

If topic URL returns 404: → Fallback to General Library Search
