Summary

Between February 2 and February 11, 2026, seven companies released agentic coding tools, including OpenAI's Codex App, GitHub's Agent HQ, Anthropic's Claude Opus 4.6, and Cursor's Composer 1.5. Many developers selected their coding tools last quarter and have not re-evaluated their choices, potentially overpaying for features or using tools inadequate for their project scope. This analysis provides over 100 tips based on testing all available tools, tracking token costs across real coding tasks, and measuring the actual value received for each dollar spent. The goal is to help developers find the optimal tool stack at the right price, ranging from free options to those costing $200 per month, to better fit their specific workflow.

Key takeaway

For developers selecting or re-evaluating agentic coding tools, you should assess your current stack against newer releases like Claude Opus 4.6 or Cursor Composer 1.5. Your team could be spending $200/month for capabilities available at $20, or using an underpowered tool for complex projects. Re-evaluate your tool choices based on token costs and project fit to optimize your workflow and budget.

Key insights

Developers often overpay or under-utilize agentic coding tools due to infrequent re-evaluation.

Principles

• Token costs vary significantly across agentic coding tools.
• Tool capabilities must match project size and complexity.

Method

The analysis involved testing all available agentic coding tools and tracking token costs across real coding tasks.

In practice

• Evaluate agentic coding tools based on token costs.
• Match tool capabilities to project requirements.
