About this skill
What does the mcp-error-code-mapper skill do?

Map application errors to MCP error codes with proper messages, error types, and recovery suggestions.

How do I install it?

Run `npx skills add a5c-ai/babysitter --skill mcp-error-code-mapper --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 a5c-ai/babysitter, a repository with 1,642 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.
