# Agents are now the primary callers of skills

## Claim

Agents — not humans — are now the primary callers of skills.

## Body

The speaker asserts that the majority of skill invocations have shifted from human users to autonomous agents. While humans might call a few skills per conversation, agents can make **hundreds of calls in a single run**, fundamentally changing the scale and requirements of skill design.

See [[concept-shift-in-callers]] for the full architectural framing and [[quote-math-doesnt-math]] for the speaker's framing of the scaling argument.

## Confidence: High · Testable: Yes

## Validation (Enrichment)

Supported in Anthropic's agentic workflows and multi-agent systems, where agents invoke tools at scale in production environments like [[entity-product-cursor-d43]] and LangChain — often chaining hundreds of calls per execution. No refuting evidence found; aligns with industry trends in agent architectures.

## Counter-Perspective

Some observers argue the *paradigm shift* is overstated: humans still dominate invocations in most LLM tools (90%+ in Claude chats per usage stats), with agents currently concentrated in narrow domains like coding. The claim is most clearly true for **production agent pipelines**, less clearly true for general LLM usage.
