Anthropic's Claude API improves agent performance with on-demand tool schema loading

By PulseAugur Editorial · [1 sources] ·

Anthropic has introduced a new method for its Claude API that significantly reduces token usage and improves accuracy by loading tool schemas on demand. Previously, agents would load all available tool schemas at the start of a request, leading to high token costs and degraded performance as the number of tools increased. The new deferred loading feature allows agents to only load necessary schemas when a task requires them, drastically cutting down context window usage and enhancing the model's ability to select the correct tool.

IMPACT Reduces token costs and improves agent accuracy by optimizing tool schema loading, potentially accelerating agent adoption.

    Loading Tool Schemas on Demand Is How Agents Scale

    <p>An agent connected to five MCP servers can burn 55,000 tokens on tool schemas before it reads the first word of your request. GitHub's server ships 35 tools at roughly 26K tokens. Slack adds 11 more at about 21K. Sentry, Grafana, and Splunk tack on a few thousand each. Add Jir…
