尽 means to use up or reach the limit (as in 尽头, the very end). Pair it with 详 detailed and you get coverage that runs all the way out: every point spelled out, nothing left over.
尽 — hand 彐 holding brush over fire 灬
Originally depicted a hand holding a brush sweeping out the last embers in a vessel, suggesting 'finishing' or 'using up.' The simplified form 尽 replaces the older 盡, but keeps the core meaning of exhausting or completing something fully.
