tool use in agents

The article is a concrete example of how agents use tools (retrieval + skills) more effectively when context is layered. Shows that tool-use effectiveness depends on clarity of tool definition.

The EDIT tool is a concrete implementation of structured tool-based interaction patterns for agents to manipulate context.

Challenges assumption that more tool definitions improve agent performance. Provides counterexample through empirical testing.

Apify Actors function as specialized tools that agents can call. This demonstrates the principle that agents extend their reasoning through external tool integration.

Agent used multiple tools in sequence (ticket reader → DB query → code editor → PR submission). The effectiveness came from combining tools with preserved context, not from the tools alone.

Agent makes effective use of external tools (arxiv/Hugging Face APIs, GPU clusters, dataset repos) but the prompt/context structure enabling tool selection is opaque

Agent has access to external tools, which is a basic pattern in agent development, but implementation details are absent
