# degradation-circuit-breaking

## Registry Trigger

**Use when**

- design fallback degradation timeout bulkhead circuit breaker and recovery behavior

**Do not use when**

- no task-local degradation circuit breaking decision is required

## Skill Role

Own bounded dependency-failure behavior under immutable gateway ceilings.

## High-Value Rules

- Consume gateway ceilings without redefining them.
- Derive local ceilings only when no gateway owns them.
- Bind phase timeouts and retry to current ceiling and failure evidence.
- Select fallback, isolation, and breaker behavior from product invariants, capacity, and recovery.
- Load only the named Reference for unresolved parameters, checks, or proof.

## Anti-Patterns

- Local success substituted for dependency-failure and recovery evidence.

## Stop Conditions

Stop when selected degradation behavior lacks an owned safety or recovery proof.

## Output Contract

- resilience plan with timeouts fallbacks circuit thresholds and recovery checks, evidence, and proof limits
