agentica-sdk SKILL.md skillA
agentica-sdk from vibeeval/vibecosystem is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add vibeeval/vibecosystem/agentica-sdk@git:20260314.f0071a0Pins git:20260314.f0071a0 in mdr.lock. Pin the fingerprint instead.

Build Python agents with Agentica SDK - @agentic decorator, spawn(), persistence, MCP integration.
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
# Agentica SDK Reference (v0.3.1)
Build AI agents in Python using the Agentica framework. Agents can implement functions, maintain state, use tools, and coordinate with each other.
## When to Use
Use this skill when:
- Building new Python agents
- Adding agentic capabilities to existing code
- Integrating MCP tools with agents
- Implementing multi-agent orchestration
- Debugging agent behavior
## Quick Start
### Agentic Function (simplest)
```python
from agentica import agentic
@agentic()
async def add(a: int, b: int) -> int:
"""Returns the sum of a and b"""
...
result = await add(1, 2) # Agent computes: 3
```
### Spawned Agent (more control)
```python
from agentica import spawn
agent = await spawn(premise="You are a truth-teller.")
result: bool = await agent.call(bool, "The Earth is flat")
# Returns: False
```
## Core Patterns
### Return Types
```python
# String (default)
result = await agent.call("What is 2+2?")
# Typed output
result: int = await agent.call(int, "What is 2+2?")
result: dict[str, int] = await agent.call(dict[str, int], "Count items")
# Side-effects only
await agent.call(None, "Send message to John")
```

How to install
mdr add vibeeval/vibecosystem/agentica-sdk@sha256:a151a77bf1e0c0d2The line at the top of this page pins the label git:20260314.f0071a0, 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.
