What This Skill Does

This skill enables AI assistants to use Perplexity's specialized models for three primary purposes:

1. Current or External Knowledge

• Documentation lookups and API references
• Library versions and recent technology changes
• Error message research
• Current events and fact checking

2. Independent Second Opinions

• Architecture and design decision validation
• Technology choice comparisons
• Alternative perspectives on problem-solving approaches
• Pre-implementation validation

3. Deep Reasoning Delegation

• Complex multi-step problem solving
• Algorithmic optimization and system design
• Trade-off analysis with many variables
• Mathematical and quantitative reasoning

Why CLI over MCP?

This skill uses the Perplexity CLI (`llm` with `llm-perplexity` plugin) instead of MCP servers because:

• Lower token usage: CLI results are more concise than MCP server overhead, preserving valuable context window space
• Faster execution: No server startup/connection delays - just direct bash command execution
• Simpler integration: Straightforward CLI tool that works anywhere bash is available
• Complementary approach: Works alongside standard web tools (WebFetch, WebSearch) rather than replacing them
