mcp-circuit-breaker
Detects MCP tool failure patterns and trips a circuit breaker to stop cascading retries. Proposes fallback alternatives and resets when the tool recovers. Triggers on "MCP failing", "tool keeps erroring", "circuit-breaker", repeated tool call failures.

# mcp-circuit-breaker — MCP Tool Failure Guard
MCP tools can fail silently or return partial results, leading to cascading retry loops that waste tokens and degrade session quality. This skill detects failure patterns, trips a circuit breaker to halt retries, proposes alternatives, and resets when the tool recovers.
> **Scope distinction**
> - Claude Code native retry: low-level transport retries (transparent, fast)
> - mcp-circuit-breaker: **session-level guard** — detects repeated semantic failures, intervenes before token waste compounds
