Uncovering Token Waste in AI Agent Sessions: Practical Fixes
Analyzing token budget inefficiencies in AI coding agents reveals 18 hidden drains that developers must address to optimize performance.
Why it mattersToken management is critical in AI coding agents, as inefficiencies can undermine performance gains. Developers must address hidden token drains to optimize costs and effectiveness, reflecting a broader shift toward smarter AI agent deployment.

18 hidden token drains in AI coding agent sessions (and practical ways to fix them)
Hi everyone, sharing some notes from running hundreds of automated agent sessions across Claude Code, Codex, and Cursor. We started logging raw API request payloads over a local proxy to see where the token budget actua…

What is one task you would trust an AI agent to do without checking?
I think the interesting question with AI agents isn't what they can do. It's what people are actually comfortable letting them do on their own. For example: Sending routine emails Updating a spreadsheet Scheduling meeti…

Anyone actually quit something because they force-fed it AI, not because the AI was bad?
Grammarly's been doing this to me for months — every doc I open has some AI rewrite suggestion sitting in the sidebar even though I turned that off in settings back in spring, and it quietly turned itself back on after…
