hummingbird
by JoannisThe hummingbird skill provides practical guidance for Hummingbird 2, a lightweight Swift HTTP server framework. Use it to install, set up, and use hummingbird for Backend Development, including routing, middleware, auth, websockets, and Fluent integration when you need a focused hummingbird guide.
This skill scores 82/100, which means it is a solid listing candidate for Agent Skills Finder. It gives directory users enough evidence to install with confidence: the trigger is explicit, the workflow is centered on a real Hummingbird 2 Swift web framework use case, and the document contains practical examples rather than placeholder content.
- Explicit trigger coverage for Hummingbird, Swift web server/API, routing, middleware, auth, websockets, and database integration.
- Substantial operational content: a valid frontmatter, long body, multiple headings, and code examples including install steps and a minimal app.
- Direct install-decision value for Swift server-side developers because it shows the framework scope and concrete usage patterns.
- No support files or scripts are included, so some behaviors rely entirely on the prose in SKILL.md.
- The repository is centered on one framework and may be narrow for users who need broader Swift backend guidance.
Overview of hummingbird skill
What hummingbird is for
The hummingbird skill helps you work with Hummingbird 2, a lightweight Swift HTTP server framework for building APIs, middleware-driven services, and backend apps with Swift Concurrency. It is best for developers who want a practical hummingbird guide instead of a generic Swift web prompt, especially when they need routing, request/response handling, auth middleware, websockets, or Fluent integration.
Who should install it
Use the hummingbird skill if you are starting a new Swift backend, porting a small server from another framework, or trying to understand Hummingbird’s core patterns before writing code. It is a good fit for backend development teams that need Swift-native server code with clear app setup, route wiring, and an opinionated starting point.
What makes it useful
The skill is strongest when you need fast path-to-running-server guidance: dependency setup, minimal application bootstrap, and the core concepts that shape how Hummingbird applications are structured. It is less about broad theory and more about getting from “I need a Swift server” to working code with fewer guesses.
How to Use hummingbird skill
Install and load the skill
Install with npx skills add Joannis/claude-skills --skill hummingbird. In practice, the hummingbird install step matters because the repository is thin: there is essentially one source of truth in SKILL.md, so the model should be pointed at the skill directly rather than inferred from unrelated files.
Start from the right inputs
For best hummingbird usage, give the model your real target: framework version, app type, and constraints. Strong prompts mention the endpoint shape, whether you need JSON, auth, websockets, or database access, and whether you are using async/await throughout. Example: “Write a Hummingbird 2 app with GET /health, JSON POST /users, and JWT auth, using Fluent only where needed.”
Read these parts first
Begin with SKILL.md, then skim the quick-start and core-concepts sections before asking for architecture advice. The most valuable repository-reading path is usually: installation, minimal application, router, request context, and then any section matching your task such as middleware, auth, websockets, or Fluent. That order keeps the hummingbird guide focused on what affects your code generation first.
Workflow that produces better output
Use the skill to turn a rough goal into a concrete scaffold: define routes, choose a context type, decide response style, and list integrations before generating code. If you only ask for “a Hummingbird app,” you will get generic scaffolding; if you specify route table, data model, and deployment assumptions, the output is much more likely to be production-shaped for hummingbird for Backend Development.
hummingbird skill FAQ
Is hummingbird only for Swift backend work?
Yes. The hummingbird skill is specifically for Hummingbird 2 and Swift server development, not frontend Swift, iOS app code, or unrelated server frameworks. If your task is not Swift HTTP server work, it is probably the wrong install.
Do I need Hummingbird experience to use it?
No, but basic Swift and server concepts help. Beginners can still use the hummingbird skill if they ask for a small, concrete app first instead of a full architecture. The safest starting point is a minimal route plus one integration at a time.
Why use this instead of a normal prompt?
A normal prompt often misses Hummingbird-specific setup details such as package dependency wiring, Router usage, or how the app boots with Application. The hummingbird skill is better when you need code that matches the framework’s actual patterns rather than a generic Swift web answer.
When should I not use it?
Do not use the hummingbird skill if you want a framework comparison, a language tutorial, or help with a server stack that is not Swift-based. It is also a poor fit if you need a high-level product spec without code, because the skill is optimized for implementation guidance.
How to Improve hummingbird skill
Give the skill the real endpoint contract
The biggest quality jump comes from specifying method, path, request body, response shape, and status codes. For example, “POST /v1/sessions accepts email/password and returns 201 with a token” is much better than “build login.” This helps hummingbird produce code that is directly usable instead of structurally incomplete.
State framework choices up front
If your app uses authentication middleware, websockets, Fluent models, or custom RequestContext, say so before generation. Hummingbird can support these patterns, but the output quality drops when the skill has to guess which integration style you want.
Tighten the first draft with one revision pass
After the first result, refine only what is wrong: route signatures, middleware order, configuration, or decoding/encoding details. Common failure modes are overbroad abstractions, missing error handling, and unclear separation between handler logic and application setup. A short second prompt with exact corrections usually improves hummingbird usage more than asking for a larger rewrite.
