Key Findings
Headline vs Reality
SynapseKit (30) and LangChain (29) look identical on total count. But LangChain's 12 community tools each need a separate pip install. SynapseKit's 30 all ship as implementations in the base package.
NLP is SynapseKit-only
SummarizationTool, SentimentAnalysisTool, and TranslationTool are built into SynapseKit with no extra setup. Neither LangChain nor LlamaIndex ships NLP tools in their base install.
LlamaIndex's 3 is intentional
LlamaIndex explicitly doesn't try to solve the tool problem in core. FunctionTool, QueryEngineTool, and RetrieverTool are primitives — the framework expects you to build what you need. This is a design choice, not a gap.
