Install
Works with every agent the skills CLI supports.
npx skills add https://github.com/actionbook/rust-skills --skill domain-web- 01
Install
Run the command in your project. The CLI asks which agents to install for.
- 02
Describe the task
Ask your agent for something this skill covers. It loads domain-web automatically when relevant.
- 03
Review the result
The agent follows the SKILL.md steps, scripts and references bundled with the skill.
SKILL.md
The instructions your agent reads when the skill is triggered.
Web Domain
Layer 3: Domain Constraints
Domain Constraints → Design Implications
| Domain Rule | Design Constraint | Rust Implication |
|---|---|---|
| Stateless HTTP | No request-local globals | State in extractors |
| Concurrency | Handle many connections | Async, Send + Sync |
| Latency SLA | Fast response | Efficient ownership |
| Security | Input validation | Type-safe extractors |
| Observability | Request tracing | tracing + tower layers |
Critical Constraints
Async by Default
RULE: Web handlers must not block
WHY: Block one task = block many requests
RUST: async/await, spawn_blocking for CPU work
State Management
RULE: Shared state must be thread-safe
WHY: Handlers run on any thread
RUST: Arc<T>, Arc<RwLock<T>> for mutable
Request Lifecycle
RULE: Resources live only for request duration
WHY: Memory management, no leaks
RUST: Extractors, proper ownership
Trace Down ↓
From constraints to design (Layer 2):
"Need shared application state"
↓ m07-concurrency: Use Arc for thread-safe sharing
↓ m02-resource: Arc<RwLock<T>> for mutable state
"Need request validation"
↓ m05-type-driven: Validated extractors
↓ m06-error-handling: IntoResponse for errors
"Need middleware stack"
↓ m12-lifecycle: Tower layers
↓ m04-zero-cost: Trait-based composition
Framework Comparison
| Framework | Style | Best For |
|---|---|---|
| axum | Functional, tower | Modern APIs |
| actix-web | Actor-based | High performance |
| warp | Filter composition | Composable APIs |
| rocket | Macro-driven | Rapid development |
Key Crates
| Purpose | Crate |
|---|---|
| HTTP server | axum, actix-web |
| HTTP client | reqwest |
| JSON | serde_json |
| Auth/JWT | jsonwebtoken |
| Session | tower-sessions |
| Database | sqlx, diesel |
| Middleware | tower |
Design Patterns
| Pattern | Purpose | Implementation |
|---|---|---|
| Extractors | Request parsing | State(db), Json(payload) |
| Error response | Unified errors | impl IntoResponse |
| Middleware | Cross-cutting | Tower layers |
| Shared state | App config | Arc<AppState> |
Code Pattern: Axum Handler
async fn handler(
State(db): State<Arc<DbPool>>,
Json(payload): Json<CreateUser>,
) -> Result<Json<User>, AppError> {
let user = db.create_user(&payload).await?;
Ok(Json(user))
}
// Error handling
impl IntoResponse for AppError {
fn into_response(self) -> Response {
let (status, message) = match self {
Self::NotFound => (StatusCode::NOT_FOUND, "Not found"),
Self::Internal(_) => (StatusCode::INTERNAL_SERVER_ERROR, "Internal error"),
};
(status, Json(json!({"error": message}))).into_response()
}
}
Common Mistakes
| Mistake | Domain Violation | Fix |
|---|---|---|
| Blocking in handler | Latency spike | spawn_blocking |
| Rc in state | Not Send + Sync | Use Arc |
| No validation | Security risk | Type-safe extractors |
| No error response | Bad UX | IntoResponse impl |
Trace to Layer 1
| Constraint | Layer 2 Pattern | Layer 1 Implementation |
|---|---|---|
| Async handlers | Async/await | tokio runtime |
| Thread-safe state | Shared state | Arc<T>, Arc<RwLock<T>> |
| Request lifecycle | Extractors | Ownership via From<Request> |
| Middleware | Tower layers | Trait-based composition |

How do I install domain-web?
Run npx skills add https://github.com/actionbook/rust-skills --skill domain-web in your project. The skills CLI detects the agents you use and copies the skill into the right folder. For Claude Code you can also place the skill folder at ~/.claude/skills/domain-web/ (personal) or .claude/skills/domain-web/ (project).
Which AI agents can use domain-web?
Any agent that supports the open Agent Skills format (a folder with a SKILL.md file), including Claude Code, Codex, Cursor, GitHub Copilot, Gemini CLI, Windsurf, Cline, OpenCode and more.
Is domain-web safe to install?
No partner security audit is available yet. Skills can run commands and scripts, so read the SKILL.md and any bundled files before installing.
Who maintains domain-web?
It is published by actionbook in actionbook/rust-skills. It has 3,164 recorded installs.

Add captions or subtitles to an existing single-subject talking-head video without editing the footage. Use for plain verbatim captions, cinematic captions embedded behind the subject, VFX captions, “炸/特效/酷炫字幕,” or a named identity from the 35-style catalog. Route by visual identity, not by backend engine. The quiet anchor rail is the default; embed every word only when the user explicitly wants a fully cinematic treatment. The workflow runs locally end to end, including transcription and subject matting; split multi-shot footage before applying it.
