Agent skills cannot execute the official skills provided by Anthropics.

[tom1978]

When using Anthropics' skills with Agno Agent, the skills fail to execute properly. I provided the pptx from https://github.com/anthropics/skills to the agent, but it cannot execute correctly. Is there incompatibility with Anthropics' skills?

Anthropic skills are designed for their native API format, which differs from Agno tools.

Why it fails:
Anthropic skills expect specific request/response structures that Agno tools dont match.

Solution: Adapt Anthropic skills to Agno tools

from agno.tools import tool
import json

# Load Anthropic skill definition
with open("anthropic_skill.json") as f:
    skill_def = json.load(f)

# Convert to Agno tool
@tool
def adapted_skill(**kwargs):
    """Adapted from Anthropic skill."""
    # Map Agno input to Anthropic format
    anthropic_input = {
        "name": skill_def["name"],
        "input": kwargs
    }
    # Execute skill logic
    result = execute_skill_logic(anthropic_input)
    return result

For PPTX generation specifically:

from agno.tools import tool
from pptx import Presentation

@tool
def create_pptx(title: str, slides: list) -> str:
    """Create a PowerPoint presentation."""
    prs = Presentation()
    for slide_content in slides:
        slide = prs.slides.add_slide(prs.slide_layouts[1])
        slide.shapes.title.text = slide_content["title"]
        slide.placeholders[1].text = slide_content["body"]
    
    path = f"/tmp/{title}.pptx"
    prs.save(path)
    return path

Alternative: Use Anthropic API directly

from anthropic import Anthropic

client = Anthropic()
response = client.messages.create(
    model="claude-3-opus",
    tools=anthropic_skills,  # Native format
    messages=[...]
)

We integrate multiple skill formats at Revolution AI — adapting to Agno tools gives you better control.

Anthropic skills not executing in Agno — let's debug:

1. Check skill registration

from agno import Agent
from agno.skills import AnthropicSkills

agent = Agent(
    skills=[AnthropicSkills()],  # Make sure this is included
    model="claude-3"
)

# Verify skills loaded
print(agent.available_skills)

2. Verify API keys

export ANTHROPIC_API_KEY="sk-ant-..."
# Check it's set
echo $ANTHROPIC_API_KEY

3. Check skill format

# Anthropic skills expect specific format
skill_input = {
    "type": "tool_use",
    "name": "skill_name",
    "input": {...}
}

4. Debug mode

import logging
logging.basicConfig(level=logging.DEBUG)

# Run agent and check logs
agent.run("Use the skill...")

5. Version compatibility

pip show agno anthropic
# Make sure versions are compatible

Common issues:

• Wrong skill name format
• Missing API key
• Model doesn't support tools
• Skill timeout

We integrate Anthropic skills at RevolutionAI. What specific skill and error message?
