🤖 Dead TODOs and FIXMEs Distract AI Agents — Google Data

Google published the 'Agent Distraction' study: across hundreds of millions of agent steps, dead bug references in code lead agents away from the task — in 13% of file-reading sessions, agents encounter them, and 83% of actions taken on them are without a developer's request. Overhead: +70% steps, +77% tokens, +105% wait time.

🌍 The first quantitative measurement of the 'technical debt tax' in agentic development: 41% of spontaneous deviations hit closed tickets, and 57% inflate the scope of work. Google cleans code using scraper agents: over 6 months, thousands of outdated TODOs were removed, with >95% of edits approved. Recommendation — presubmit analyzers and corpus scanners.

👤 Running agents (Gemini CLI, Copilot, Cursor)? Dead TODOs/FIXMEs invisibly increase task costs — clean them up before large agentic runs.
