# Developer SDK & Plug-in Framework

### Programmatic Control over Autonomous Agents

#### Objective

Enable developers to **build, test, and deploy custom autonomous agents** within the UA1 protocol by exposing low-level hooks, runtime scaffolding, and secure modular skill injection pipelines.

Agents are packaged and deployed as containerized microservices running isolated execution environments, each with statically defined permissions and memory access scopes. The framework supports live skill loading, event-driven logic, and agent-to-agent communication patterns.

#### Architecture Summary

| Component              | Description                                                               |
| ---------------------- | ------------------------------------------------------------------------- |
| **Agent Runtime Core** | Lightweight, container-ready execution engine (Python or JS context)      |
| **Skill Engine**       | Loads custom functions, tools, conditionals, and API calls at runtime     |
| **Manifest Compiler**  | Converts YAML agent definition into executable, permission-aware artifact |
| **Telemetry Layer**    | Streams live logs, error traces, and memory diffs for observability       |
| **State Manager**      | Enforces memory boundaries, version checkpoints, rollback on failure      |

#### Agent File Structure Example

```bash
bashCopierModifiermy-agent/
├── agent.yaml                # Agent manifest (meta + policy + skill bindings)
├── skills/
│   ├── pricing_bot.py        # Tool: price comparison
│   ├── alert_sender.py       # Tool: email/telegram notifications
├── memory/
│   └── init_knowledge.json   # Bootstrapped memory (optional)
├── tests/
│   └── test_agent_flow.py    # Pytest-compatible test suite
├── Dockerfile                # Runtime container
├── logs/                     # Local telemetry output
```

#### Key Features

| Feature                   | Technical Implementation                                                          |
| ------------------------- | --------------------------------------------------------------------------------- |
| **Agent Manifest System** | YAML-based schema with role, skills, auth scopes, resource constraints            |
| **Skill Modules**         | Python/Node modules with `execute()` entrypoints; hot-swappable via plugin loader |
| **Runtime Isolation**     | Each agent runs in its own Docker container or Firecracker VM, memory-scoped      |
| **CLI Toolkit**           | Create, compile, test, deploy agents; supports versioning + local emulation       |
| **Monitoring Hooks**      | Custom log levels, memory deltas, error codes, and task success callbacks         |

#### Agent Manifest (YAML) Example

```yaml
yamlCopierModifieragent:
  id: "shopping_analyst_v1"
  language: "python"
  description: "Compares e-commerce pricing across platforms"
  memory_policy:
    encryption: true
    max_context_window: 4096
  permissions:
    - fetch_http
    - write_to_owner_log
    - call_api("amazon", "price_scraper")
  skills:
    - skills/pricing_bot.py
    - skills/alert_sender.py
```

#### Build & Deployment Lifecycle

1. **Scaffold Agent**

   ```bash
   bashCopierModifierera-cli init my-agent --template basic-python
   ```
2. **Write Skills**
   * Each file must export an `execute(input, context)` method
   * Tools are versioned independently via semantic versioning
3. **Test Locally**

   ```bash
   bashCopierModifierera-cli test
   ```
4. **Deploy**

   ```bash
   bashCopierModifierera-cli deploy --env=production
   ```
5. **Monitor**

   ```bash
   bashCopierModifierera-cli logs --tail
   ```
6. **Update or Rollback**
   * Skills hot-reloadable in non-critical agents
   * Full rollback supported for production deployments

#### Advanced Capabilities

| Capability                | Details                                                                       |
| ------------------------- | ----------------------------------------------------------------------------- |
| **Agent Federation**      | Agents can call one another’s skills across containers with auth relay        |
| **Skill Marketplace**     | Signed skill packages (.erskill) can be published and reused                  |
| **Performance Profiling** | Execution time, memory usage, failure rates available via observability tools |
| **Simulated Training**    | Emulator supports complex input chains and prompt randomization               |
