Install
Works with every agent the skills CLI supports.
npx skills add https://github.com/actionbook/rust-skills --skill domain-iot- 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-iot 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.
IoT Domain
Layer 3: Domain Constraints
Domain Constraints → Design Implications
| Domain Rule | Design Constraint | Rust Implication |
|---|---|---|
| Unreliable network | Offline-first | Local buffering |
| Power constraints | Efficient code | Sleep modes, minimal alloc |
| Resource limits | Small footprint | no_std where needed |
| Security | Encrypted comms | TLS, signed firmware |
| Reliability | Self-recovery | Watchdog, error handling |
| OTA updates | Safe upgrades | Rollback capability |
Critical Constraints
Network Unreliability
RULE: Network can fail at any time
WHY: Wireless, remote locations
RUST: Local queue, retry with backoff
Power Management
RULE: Minimize power consumption
WHY: Battery life, energy costs
RUST: Sleep modes, efficient algorithms
Device Security
RULE: All communication encrypted
WHY: Physical access possible
RUST: TLS, signed messages
Trace Down ↓
From constraints to design (Layer 2):
"Need offline-first design"
↓ m12-lifecycle: Local buffer with persistence
↓ m13-domain-error: Retry with backoff
"Need power efficiency"
↓ domain-embedded: no_std patterns
↓ m10-performance: Minimal allocations
"Need reliable messaging"
↓ m07-concurrency: Async with timeout
↓ MQTT: QoS levels
Environment Comparison
| Environment | Stack | Crates |
|---|---|---|
| Linux gateway | tokio + std | rumqttc, reqwest |
| MCU device | embassy + no_std | embedded-hal |
| Hybrid | Split workloads | Both |
Key Crates
| Purpose | Crate |
|---|---|
| MQTT (std) | rumqttc, paho-mqtt |
| Embedded | embedded-hal, embassy |
| Async (std) | tokio |
| Async (no_std) | embassy |
| Logging (no_std) | defmt |
| Logging (std) | tracing |
Design Patterns
| Pattern | Purpose | Implementation |
|---|---|---|
| Pub/Sub | Device comms | MQTT topics |
| Edge compute | Local processing | Filter before upload |
| OTA updates | Firmware upgrade | Signed + rollback |
| Power mgmt | Battery life | Sleep + wake events |
| Store & forward | Network reliability | Local queue |
Code Pattern: MQTT Client
use rumqttc::{AsyncClient, MqttOptions, QoS};
async fn run_mqtt() -> anyhow::Result<()> {
let mut options = MqttOptions::new("device-1", "broker.example.com", 1883);
options.set_keep_alive(Duration::from_secs(30));
let (client, mut eventloop) = AsyncClient::new(options, 10);
// Subscribe to commands
client.subscribe("devices/device-1/commands", QoS::AtLeastOnce).await?;
// Publish telemetry
tokio::spawn(async move {
loop {
let data = read_sensor().await;
client.publish("devices/device-1/telemetry", QoS::AtLeastOnce, false, data).await.ok();
tokio::time::sleep(Duration::from_secs(60)).await;
}
});
// Process events
loop {
match eventloop.poll().await {
Ok(event) => handle_event(event).await,
Err(e) => {
tracing::error!("MQTT error: {}", e);
tokio::time::sleep(Duration::from_secs(5)).await;
}
}
}
}
Common Mistakes
| Mistake | Domain Violation | Fix |
|---|---|---|
| No retry logic | Lost data | Exponential backoff |
| Always-on radio | Battery drain | Sleep between sends |
| Unencrypted MQTT | Security risk | TLS |
| No local buffer | Network outage = data loss | Persist locally |
Trace to Layer 1
| Constraint | Layer 2 Pattern | Layer 1 Implementation |
|---|---|---|
| Offline-first | Store & forward | Local queue + flush |
| Power efficiency | Sleep patterns | Timer-based wake |
| Network reliability | Retry | tokio-retry, backoff |
| Security | TLS | rustls, native-tls |

How do I install domain-iot?
Run npx skills add https://github.com/actionbook/rust-skills --skill domain-iot 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-iot/ (personal) or .claude/skills/domain-iot/ (project).
Which AI agents can use domain-iot?
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-iot 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-iot?
It is published by actionbook in actionbook/rust-skills. It has 2,758 recorded installs.

This skill should be used when the user wants to "write agent code", "build an agent with ADK", "add a tool", "create a callback", "define an agent", "use state management" — in a project that needs ADK (Agent Development Kit) API patterns and code examples. It provides a quick reference for agent types, tool definitions, orchestration patterns, callbacks, state management, the graph Workflow API, and reference recipes to study. Do NOT use for scaffolding (use google-agents-cli-scaffold) or deployment (use google-agents-cli-deploy).
embedded-captions

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.
