Novel Writing Enters the Multi-Agent Era — Introducing FeelFish 3.0

Official Announcement · 2026 · FeelFish Team

While other AI tools are still helping you tweak a single line of dialogue through a simple chat interface, FeelFish has been asking a much bigger question: What would writing look like if every stage of the creative process had its own dedicated AI expert?

Today, we have the answer.

FeelFish 3.0 is built on the industry's most advanced MCP, multi-agent collaboration, and reusable Skill architecture. This is more than a feature update — it's a shift in the creative paradigm, bringing agent-powered collaborative writing out of the realm of concept and onto every writer's desktop.

Meet the New Trinity: Solutions, Agents, and Skills

Everything in FeelFish 3.0 is built around three core concepts. Understand them, and you hold the key to crafting your own personalized writing workflow.

📋 Solution

A Solution determines which agents are active in a conversation, who leads, and who assists. Switching solutions means swapping out an entire agent configuration in one click — no need to adjust settings one by one.

Built-in Solutions: "Professional Assist," "Multi-Agent," "Smart Planning," "Adventure Mode," and more — ready to use out of the box;
Custom Solutions: Automatically generated when you configure your agent setup in the panel; saved to your project's .feelfish directory and scoped to that project only;
Marketplace Solutions: Download solutions shared by other writers and apply them instantly.

🤖 Agent

An Agent is an AI role that handles a specific type of task, complete with its own system prompt, available tools, and linked skills.

Primary Agent: Coordinates the overall workflow; intelligently decides whether to delegate a subtask to a more specialized sub-agent based on its own role definition and the descriptions of other agents;
Built-in Agents: Professional Assist, Planner, Writer, Editor, Reviewer, and more — cannot be deleted, but can be enabled/disabled per project and configured with skill overrides;
Custom Agents: Define behavior and constraints in Markdown; saved as .feelfish/agents/<id>.md and associable with any skill.

📚 Skill

A Skill is a reusable "instruction document" that can be shared across multiple agents. It captures writing standards, stylistic rules, or creative processes — and agents read it on demand at runtime, so your hard-won expertise actually shapes the output.

Skills use SKILL.md as their main file, stored under .feelfish/skills/<skill-name>/;
Each skill has a name (identifier) and description (brief summary) that agents use to decide whether to invoke it for a given task;
Skills can be imported from local files, shared to the marketplace, and reused across your team in one click.

No More Going It Alone

The core problem with traditional AI writing tools: one model is expected to simultaneously serve as outliner, style consultant, line editor, and logic reviewer — and ends up doing all of them at 60%.

FeelFish 3.0's multi-agent system lets you assemble a professional team:

Planner Agent handles worldbuilding and chapter outlines;
Writer Agent focuses on generating prose;
Editor Agent polishes the language and strips out the AI aftertaste;
Reviewer Agent catches logic gaps and inconsistencies.

Four specialists, each in their lane, collaborating to bring your manuscript to life. The primary agent acts like a seasoned editor-in-chief — knowing when to hand work off to the right person rather than doing everything itself.

Turn Your Creative Experience Into Reusable Wisdom

Every experienced writer has a personal playbook. Until now, that playbook only lived in your head. With FeelFish 3.0, it can become a Skill — callable by any of your agents at any time.

Skill Example	Linked Agent	Result
Outline structure guide	Planner Agent	Every outline follows your preferred format
De-AI-ification editing guide	Editor Agent	Prose feels more like your own voice
Character description handbook	Writer Agent	Characters are consistent, vivid, and believable
World-setting reference doc	All agents	No contradictions across the entire manuscript

Creating a skill is straightforward: open the Skills tab, create a new skill, write your guidelines in Markdown, then link it to the relevant agent under "Associated Skills." You can also import existing documents from your local files or browse skills shared by other writers on the marketplace.

Five Steps to Your Custom Writing Pipeline

Start with a built-in solution and run through it once — begin with "Multi-Agent" or "Professional Assist" to get a feel for agent collaboration before customizing anything.
Create 1–2 core skills — capture the writing rules you care about most: your outline format, character sheet template, stylistic no-gos. Write them once, use them forever.
Link skills to the right agents — make sure each specialist reads the right instruction doc, so you never have to re-teach the AI from scratch.
Create custom agents as needed — if the built-in roles aren't enough, define your own: a "dedicated outliner," an "editor who only touches dialogue." Write their behavior guidelines clearly in Markdown.
Share to the marketplace, or draw inspiration from it — browse solutions, agents, and skills shared by the community; apply them with one click, or publish your own to help other writers.

💡 Tip: There's no need to "create a solution" manually. Just configure your agents in the panel — choose who's in and who's primary — and your custom solution is formed automatically.

The Foundation: MCP Makes Agents Actually Do Things

FeelFish 3.0 is built on best practices from MCP (Model Context Protocol). Agents don't just reply in a chat window — they can read files, invoke tools, retrieve content from your knowledge base, and execute creative tasks directly within your real project directory.

Every configuration — skill files, agent definitions, solution setups — is stored as plain-text Markdown inside the .feelfish project directory. Version-controllable, portable, and shareable with your team. Your writing workflow truly belongs to you.
