The AI Skill I Rely On Daily — Priscila Andre de Oliveira, Sentry
May 27, 2026 · 17:05
Priscila Andre de Oliveira, a senior software engineer at Sentry, reveals that 67% of her AI usage is for comprehension and only 2% for code generation, based on analyzing 116 of her own Claude sessions. Working in Sentry's 15-year-old codebase with 100 PRs merged daily and 100,000 organizations depending on it, she built a personal skill called 'Catch Me Up' with six exploration modes (architecture, conventions, feature traces, syntax, testing, history). She argues that understanding what the agent found before letting it plan and implement prevents misaligned mental models that produce slop code. The episode emphasizes that in large, complex codebases, AI's biggest unlock is comprehension, not generation, and advises developers to align their mental models before prompting.
