T3 Code Cuts Agent Tool Context 79%

This is the right kind of agent optimization: reduce prompt tax before demanding a smarter model. The “4x better” claim is best read as workflow efficiency, not a fourfold leap in model intelligence.

• –Tool search loads relevant schemas on demand instead of front-loading every tool definition.
• –T3 merged 18 related tools into action-based interfaces, simplifying tool selection.
• –Internal evals reached 99% on Sonnet, Sol, and Astra, with Opus at 96%.
• –The biggest gains should appear in multi-tool Claude and MCP workflows; small toolsets will benefit less.
• –The result validates context engineering as a core coding-agent feature, not merely an implementation detail.
