Perplexity Sonar

Archetype: AI (Tool) — implements ToolAdapter.invoke(...) for grounded retrieval with citations.

What it does

@loop-engine/adapter-perplexity implements ToolAdapter.invoke() against the Sonar chat API. You get answer text plus structured citations for audit and evidence attachment. Use it where provenance matters more than open-ended generation.

When to use it

• Regulatory or policy research with domain allowlists
• Supplier, market, or news checks inside a governed Loop
• Any step where you must show which sources justified the output
