Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# Middleware Chain Designer Skill ## Overview This skill designs middleware and interceptor chain architectures that enable SDK extensibility through pluggable request/response processing. ## Capabilities - Design middleware interfaces and contracts - Implement interceptor chains with ordering - Support before/after hooks for requests - Enable custom transport implementations - Implement retry and circuit breaker middleware - Design logging and tracing interceptors - Support middleware composition - Configure middleware priority ordering ## Target Processes - Plugin and Extension Architecture - Custom Transport and Middleware - SDK Architecture Design ## Integration Points - SDK core HTTP clients - Authentication handlers - Logging frameworks - Retry libraries - Custom transports ## Input Requirements - Extensibility requirements - Middleware ordering needs - Hook types required - Composition patterns - Transport abstraction needs ## Output Artifacts - Middleware interface definitions - Interceptor chain implementation - Built-in middleware (logging, retry) - Transport abstraction layer - Middleware composition utilities - Documentation and examples ## Usage Example ```yaml skill:

What does the middleware-chain-designer skill do?
Design middleware and interceptor chains for SDK extensibility
How do I install it?
Run `npx skills add a5c-ai/babysitter --skill middleware-chain-designer --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.
