Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# Uncertainty Detector Catch yourself when you're guessing but sounding certain. ## The problem AI tends to present uncertain answers with confident language. "The function returns null" sounds certain even when you haven't checked. This is how hallucinations become accepted as fact. ## Uncertainty signals to watch for ### In your own thinking When you notice yourself: - Answering without having read the file -> STOP, read it first - Using training data instead of tool results -> STOP, search the codebase - Filling in gaps with "reasonable assumptions" -> STOP, verify or flag - Choosing between multiple possible answers -> STATE the options - Extrapolating from one file to another -> VERIFY the other file ### In your language Replace confident-uncertain phrases: | Don't say (hides uncertainty) | Say instead (honest) | |-------------------------------|---------------------| | "The function returns X" | "Let me check what the function returns" | | "This should work" | "Based on X, this should work.

What does the uncertainty-detector skill do?
Detects when Claude is uncertain but presenting answers confidently. Teaches Claude to recognize and communicate uncertainty clearly instead of masking it with confident language.
How do I install it?
Run `npx skills add majiayu000/claude-skill-registry --skill uncertainty-detector --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From majiayu000/claude-skill-registry, a repository with 534 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
