Best A2A Agents for Content Creation in 2026

Content creation is the use case where A2A's composability pays off immediately. You can wire a research agent to a writing agent to an editing agent, and each one is independently deployable, replaceable, and testable. No monolithic prompt chain. No brittle glue code.

Here are the agents worth evaluating right now, what each does well, and where each falls short.

CrewAI Content Crew

Framework: CrewAI with A2A server/client support

The strongest option if you want a multi-agent content pipeline out of the box. CrewAI's native A2A support means you define a crew with specialized roles -- researcher, writer, editor -- and expose the whole crew as a single A2A endpoint.

from crewai import Agent, Task, Crew
from crewai.a2a import A2AServerConfig

researcher = Agent(
    role="Content Researcher",
    goal="Find accurate, current information on the given topic",
    backstory="Expert researcher who finds primary sources and recent data",
    llm="gpt-4o",
)

writer = Agent(
    role="Content Writer",
    goal="Write engaging, well-structured content for developers",
    backstory="Technical writer who explains complex topics clearly",
    llm="gpt-4o",
)

editor = Agent(
    role="Content Editor",
    goal="Polish content for clarity, accuracy, and tone",
    backstory="Senior editor who catches errors and tightens prose",
    llm="gpt-4o",
    a2a=A2AServerConfig(url="http://localhost:8000"),
)

research_task = Task(
    description="Research the topic: {topic}. Find 3-5 key points with sources.",
    expected_output="Research brief with key findings and source URLs",
    agent=researcher,
)

writing_task = Task(
    description="Write a blog post based on the research brief. 800-1200 words.",
    expected_output="Complete blog post in markdown format",
    agent=writer,
)

editing_task = Task(
    description="Edit the blog post for clarity, accuracy, and engagement.",
    expected_output="Final polished blog post ready for publication",
    agent=editor,
)

crew = Crew(
    agents=[researcher, writer, editor],
    tasks=[research_task, writing_task, editing_task],
    verbose=True,
)

What works: The sequential pipeline (research -> write -> edit) produces noticeably better output than a single-agent prompt. Each agent focuses on one job. The editor catches mistakes the writer makes. CrewAI handles task handoffs automatically.

What doesn't: No streaming support. Long content takes 30-60 seconds to complete, and the client waits with no feedback. The internal multi-agent loop adds latency that a single well-crafted prompt would avoid. For a 200-word social media post, three agents are overkill.

Quality: 8/10. Best multi-step output quality. The editing pass makes a measurable difference.

See the CrewAI tutorial for the full build walkthrough.

Genkit Content Agent

Framework: Firebase Genkit

Good choice for TypeScript teams already in the Google ecosystem. Genkit agents expose A2A endpoints with minimal configuration, and the structured output support is solid for generating content with metadata (titles, tags, SEO descriptions).

import { genkit } from "genkit";
import { googleAI, gemini15Pro } from "@genkit-ai/googleai";

const ai = genkit({
  plugins: [googleAI()],
});

const contentFlow = ai.defineFlow(
  {
    name: "generateContent",
    inputSchema: z.object({
      topic: z.string(),
      contentType: z.enum(["blog", "social", "email", "docs"]),
      tone: z.enum(["professional", "casual", "technical"]).default("technical"),
      maxWords: z.number().default(800),
    }),
  },
  async (input) => {
    const { text } = await ai.generate({
      model: gemini15Pro,
      prompt: `Write a ${input.contentType} about "${input.topic}".
Tone: ${input.tone}. Target length: ${input.maxWords} words.
Format as markdown with a clear title and sections.`,
      config: { temperature: 0.7 },
    });

    return { content: text, metadata: { topic: input.topic, type: input.contentType } };
  }
);

What works: Fast iteration. Type safety from Zod schemas. Gemini 1.5 Pro handles long-form content well. Structured input/output means clients can specify content type, tone, and length precisely.

What doesn't: Single-agent -- no research or editing pass. The output quality is entirely dependent on the model and prompt. No built-in fact-checking or source verification.

Quality: 7/10. Good for first drafts. Needs human review for anything published under your brand.

Blog Writer Agent

Framework: A2A Python SDK (direct)

A minimal, focused agent that does one thing: generate blog posts from a topic and outline. Built directly on the A2A Python SDK without a higher-level framework.

from a2a.server import A2AServer
from a2a.types import AgentCard, AgentSkill

card = AgentCard(
    name="Blog Writer",
    description="Generates developer blog posts from topics and optional outlines",
    version="1.0.0",
    url="http://localhost:9000",
    skills=[
        AgentSkill(
            id="write-blog-post",
            name="Write Blog Post",
            description="Generate a technical blog post. Provide a topic and optional outline.",
            tags=["blog", "writing", "technical"],
            examples=[
                "Write a blog post about WebSocket performance optimization",
                "Write a 1000-word post about Kubernetes networking with an outline: intro, pod networking, services, ingress, conclusion",
            ],
        )
    ],
)

What works: Simple, predictable, easy to understand and extend. No framework overhead. You control the prompt entirely. Works as a building block in a larger pipeline -- pair it with a research agent upstream and an editing agent downstream.

What doesn't: No multi-agent orchestration. No research. No self-review. Output quality is single-pass LLM generation. You get what the model gives you on the first try.

Quality: 6/10. Functional but basic. Best used as one component in a larger system, not as a standalone content solution.

Social Media Agent

Framework: Custom with platform-specific formatting

Built for platform-specific content: LinkedIn posts, X threads, newsletter intros. The value is in the formatting rules and character limits baked into the agent, not raw generation quality.

PLATFORM_RULES = {
    "linkedin": {
        "max_chars": 3000,
        "format": "professional, thought-leadership style",
        "structure": "Hook line, 3-4 short paragraphs, call to action",
        "hashtags": 3,
    },
    "x_thread": {
        "max_chars_per_tweet": 280,
        "max_tweets": 10,
        "format": "punchy, direct, numbered thread",
        "structure": "Hook tweet, key points as individual tweets, final CTA tweet",
        "hashtags": 2,
    },
    "newsletter": {
        "max_words": 500,
        "format": "conversational, brief",
        "structure": "TL;DR, main insight, one example, link to full post",
        "hashtags": 0,
    },
}

async def generate_social_content(topic: str, platform: str, context: str = ""):
    rules = PLATFORM_RULES[platform]

    prompt = f"""Create a {platform} post about: {topic}
Format: {rules['format']}
Structure: {rules['structure']}
{"Max characters: " + str(rules.get('max_chars', '')) if 'max_chars' in rules else ''}
{"Max words: " + str(rules.get('max_words', '')) if 'max_words' in rules else ''}
Include {rules['hashtags']} relevant hashtags.
{"Additional context: " + context if context else ''}"""

    return await llm.generate(prompt)

Connect to it from a coordinator agent:

import httpx

async def create_social_campaign(topic: str):
    """Generate content for all platforms from one topic."""
    agent_url = "http://social-agent:9000"

    results = {}
    for platform in ["linkedin", "x_thread", "newsletter"]:
        response = await httpx.post(
            agent_url,
            json={
                "jsonrpc": "2.0",
                "id": f"social-{platform}",
                "method": "message/send",
                "params": {
                    "message": {
                        "role": "user",
                        "parts": [{
                            "type": "text",
                            "text": f"Create a {platform} post about: {topic}"
                        }],
                    }
                },
            },
            timeout=60,
        )
        results[platform] = response.json()

    return results

What works: Platform-aware formatting means you do not get a LinkedIn post that reads like a tweet or a thread that reads like an email. The character limits and structural constraints produce better-targeted output than a generic "write me a post" prompt.

What doesn't: No research capability. No image generation or selection. The content is only as good as the topic input -- garbage in, formatted garbage out.

Quality: 7/10. Strong for format-specific output. Weak on substance unless paired with a research agent.

Artinet Content Builder

Framework: Artinet SDK (TypeScript)

If none of the above fit your workflow, Artinet lets you build a custom content agent fast. It handles Agent Card generation, A2A endpoint setup, and task routing. You write the content logic.

import { ArtinetAgent } from "artinet-sdk";

const contentAgent = new ArtinetAgent({
  name: "content-builder",
  description: "Custom content creation agent with brand guidelines",
  skills: [
    {
      id: "branded-content",
      name: "Branded Content",
      description: "Generate content following specific brand voice and style guidelines",
      tags: ["content", "brand", "marketing"],
    },
    {
      id: "content-repurpose",
      name: "Repurpose Content",
      description: "Transform existing content into different formats (blog to social, docs to tutorial)",
      tags: ["content", "repurpose", "transform"],
    },
  ],
});

contentAgent.onTask("branded-content", async (task) => {
  const brandGuidelines = await loadBrandGuidelines();
  const result = await generateWithBrand(task.message, brandGuidelines);
  return { type: "text", text: result };
});

contentAgent.onTask("content-repurpose", async (task) => {
  const sourceContent = task.message;
  const targetFormat = task.metadata?.targetFormat || "social";
  const result = await repurposeContent(sourceContent, targetFormat);
  return { type: "text", text: result };
});

contentAgent.start({ port: 8080 });

What works: Full control. You can bake in your brand guidelines, style rules, and content templates. The repurpose skill -- turning a blog post into social media threads, email snippets, and documentation updates -- is where this shines.

What doesn't: You are building and maintaining it yourself. No pre-built research, editing, or review capabilities. LangChain under the hood means one more dependency to manage.

Quality: 7/10. Quality ceiling is high because you control everything. Quality floor is low because you are responsible for everything.

Recommendations by Use Case

Full content pipeline (blog posts, articles): CrewAI Content Crew. The research-write-edit chain produces the best output. Worth the latency.

Quick social media drafts: Social Media Agent. Platform-specific formatting saves time. Pair with a human review step.

TypeScript/Google ecosystem: Genkit Content Agent. Native Gemini support and type safety. Good developer experience.

Custom brand voice: Artinet Content Builder. Full control over tone, style, and formatting rules. More work upfront, better long-term fit.

Building block for a larger system: Blog Writer Agent. Simple, predictable, composable. Slot it into a pipeline with other specialized agents.

Composing a Content Pipeline

The real power is combining agents. Here is a realistic pipeline:

Research Agent (finds data, sources, trends)
    |
    v
CrewAI Writer (produces first draft from research)
    |
    v
Social Media Agent (creates platform-specific versions)
    |
    v
Editor Agent (reviews everything for quality)

Each agent runs independently, communicates over A2A, and can be replaced without touching the others. The research agent could be the LangChain Data Agent pulling from your analytics. The editor could be a human-in-the-loop agent that routes drafts for approval.

---

The ecosystem is still early. Most content agents are thin wrappers around LLM prompts. The ones that stand out add structure -- multi-step pipelines, platform rules, brand guidelines -- on top of the raw generation. That structure is what makes A2A content agents genuinely useful rather than just a chatbot with an HTTP endpoint.
