AI coding agent brief
ProblemVague prompts to coding agents (Cursor, Claude Code, Copilot) produce code that misses the point.
Add dark mode to our React app; don't touch the charts library
Goal: user-selectable dark theme, saved per user, default follows the OS.
Out of scope: src/charts/** (do not edit).
Done when: toggling theme updates all pages; contrast ≥ 4.5:1; existing tests pass.
Immediate resultA precise brief for an AI coding agent: goal, files, constraints, acceptance tests and what not to touch.
