middleware-design SKILL.md skillA
middleware-design from andreibesleaga/gabbe is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add andreibesleaga/gabbe/middleware-design@git:20261014.de0823cPins git:20261014.de0823c in mdr.lock. Pin the fingerprint instead.

Designing robust middleware chains (Auth, Rate Limiting, Logging). Use when: middleware design.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# middleware-design Skill
## Goal
This skill guides the creation of the request processing pipeline ("The Onion Architecture").
## Steps
## 1. The Standard Pipeline (Order Matters)
1. **Request ID**: Generate `trace_id` immediately. (Before logs).
2. **CORS**: Allow/Block origins. (Before processing).
3. **Body Parser**: JSON/Form parsing. (Limit size to prevent DoS).
4. **Rate Limiter**: Token Bucket algorithm. (Stop abuse cheaply).
5. **Authentication**: Verify JWT/Session. (Who is it?).
6. **Authorization**: Check Roles/Scopes. (Can they do it?).
7. **Validation**: Zod/Pydantic schema check. (Is input valid?).
8. **Controller**: Business Logic.
9. **Error Handler**: Catch exceptions, format JSON, scrub sensitive data.
## 2. Implementation Rules
- **Fail Fast**: If Rate Limit check fails, return 429 immediately. Do not parse body.
- **Context Passing**: Pass `user` and `trace_id` via Context (Go/React) or Request Object (Express/FastAPI).
- **No Business Logic**: Middleware should be generic. Don't query `SELECT * FROM orders` in middleware.
## 3. Specific Patterns
### Rate Limiting
- **Global**: 1000 req/min/IP.
- **Route-Specific**: Login = 5 req/min/IP.

How to install
mdr add andreibesleaga/gabbe/middleware-design@sha256:b1380ffb65d9a2deThe line at the top of this page pins the label git:20261014.de0823c, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
