Diagnose cucurbit downy mildew (Pseudoperonospora cubensis) and related early-stage foliar diseases on cucumber, melon, watermelon, and pumpkin. Use when the farmer sends a photo of a leaf with yellowing, angular blotches, or grey mould on the underside, OR when overnight humidity and temperature data match the infection envelope. Returns a severity score (0-3), a stage classification, and a concrete treatment plan with dosages and local supplier references.

From the source SKILL.md

This skill is the diagnostic core that Tio Cumbana invokes every time the farmer asks "is my cucumber OK?" or the vigilance loop sees a humidity spike. It's separated from the conversational system prompt so the same logic powers reactive replies, proactive triggers, and any future Claude Desktop / Claude Code integration the project picks up.

What this skill does

Diagnose Mildew is a community-contributed Claude Code skill in the general-misc sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/diagnose-mildew/ and loads when your prompt matches the skill's trigger.
