You built an AI agent using a no-code platform. You gave it instructions. You hit "run." And the results? Maybe they're okay-ish, sometimes wildly off-topic, or just... meh. It feels less like you've hired a super-smart assistant and more like you're managing a confused intern who needs constant supervision, right?

Here’s the deal: The problem often isn't the AI itself. It's how we're talking to it. Vague instructions, missing guardrails, no plan for when things go sideways – these are recipes for AI chaos.

But what if you could learn from the folks building the most advanced AI assistants out there? We peeked under the hood of top AI tools like Manus, Lovable, Replit, Windsurf, Devin, Cursor, and v0 (you can see their detailed instructions here) and found something fascinating. While they tackle complex coding tasks, the way they're instructed holds universal secrets for making any AI agent work better.

Forget the complicated code. We've translated their core operating principles into five straightforward strategies you can use right now in platforms like MindPal to build an AI workforce that doesn't just follow orders, but actually gets the job done reliably. At the end of the blog post, you'll also find a simple framework that you can apply to any AI agents you're building to make them less rogue, more rockstar.

Principle 1: Give Your Agent a Clear Job Title and Mission (Role & Goal Setting)

Why it Matters

Just like hiring a human, an AI needs to know its role and the specific objective of the task at hand. Vagueness leads to confusion and off-task behavior. Without a clear identity and purpose, your agent is flying blind.

Lessons from the Pros

Top tools explicitly define the agent's persona and mission right at the start:

• Cursor: You are a powerful agentic AI coding assistant trained by Cursor. You are pair programming with a USER to solve their coding task. (Lines 1, 3)
• Devin: You are Devin, a software engineer. You are querying this user about how they want you to achieve a goal. Your mission is to accomplish the task using the tools at your disposal, after you have clarified the goal. (Line 1)
• Lovable: You are Lovable, an AI editor that creates and modifies web applications. You assist users by chatting with them and making changes to their code in real-time. (Lines 2-3, 71)
• Manus: Defines its expertise clearly: You excel at the following tasks: 1. Information gathering... 2. Data processing... 3. Writing... (Lines 4-10)

How to Apply This to Your No-Code Agents

Clearly define your agent's identity and primary function within its core instructions (like MindPal's System Instructions). Think: "What is this agent's job title?" Is it a "Customer Feedback Analyzer," a "Report Summarizer," or a "Social Media Post Drafter"? Then, for each specific task or workflow you assign, start the prompt with a crystal-clear goal statement. For example: "Your objective is to analyze the attached customer survey results and categorize each response into 'Positive,' 'Negative,' or 'Neutral'." Giving this context upfront dramatically improves focus. If you're new to agents, check out this Introduction to Agents guide.

Actionable Tip

Start your agent's core instructions with: "You are a [Specific Role, e.g., Marketing Content Summarizer]. Your primary purpose is to [Main Function, e.g., condense lengthy articles into key bullet points]."

Principle 2: Break It Down – No One Likes Ambiguous Instructions (Task Decomposition & Planning)

Why it Matters

Complex tasks overwhelm AI just like they overwhelm people. Asking an agent to perform a multi-stage process with a single, broad instruction invites errors and omissions. Breaking down tasks into smaller, sequential steps ensures clarity and keeps the agent focused.

Lessons from the Pros

Advanced agents rely heavily on planning and step-by-step execution:

• Devin: Explicitly uses planning tags: You should make a plan by using the <suggest_plan> command. Then, you should execute the plan step by step. (Lines 41-45)
• Manus: Operates in an "agent loop" (Analyze, Select Tools, Execute, Iterate) and uses a Planner module that provides numbered steps: Planner provides a numbered, step-by-step pseudocode plan... (Lines 27-33, 53-60)
• Cursor: Provides structured guidance within specific contexts, like numbered rules for making code changes: <making_code_changes> ... 1. Respond by calling the apply_edit tool... (Lines 18-29)
• v0: Uses thinking tags for planning before generating output: <Thinking> The user wants a React component... I should plan the structure first... </Thinking> (Prompt section: Planning)

How to Apply This to Your No-Code Agents

For any process involving multiple steps, structure your prompts with clear, numbered instructions. Instead of "Summarize the report and draft an email," use: "1. Read the attached report. 2. Identify the three key findings. 3. Summarize these findings in bullet points. 4. Draft an email to the team leader including this summary." A more robust approach in platforms like MindPal is using Multi-Agent Workflows. Each step becomes a distinct Agent Node, handling one part of the task. This forces decomposition and allows you to manage the flow, passing information between steps using features like Variables. Consider using specialized nodes like the Orchestrator-Worker Node for managing complex sub-tasks. Need inspiration? Check out these proven multi-agent AI workflows.

Actionable Tip

If your task takes more than 2-3 distinct actions, use a numbered list in your prompt or, ideally, build a multi-step workflow with separate nodes for each action.

Principle 3: Explain the Toolbox and the Rules (Tool Usage & Constraints)

Why it Matters

An AI needs to know what tools it can use (like web search, accessing specific documents, calling an API) and, just as importantly, what it can't or shouldn't do. Setting clear rules around tool usage prevents mistakes, ensures focus, and guides the agent to use resources effectively.

Lessons from the Pros

Top agents have very specific instructions about their tools and operational constraints:

• Cursor: Has strict rules for tool interaction: NEVER refer to tool names when speaking to the USER. and Only calls tools when they are necessary. It also provides detailed descriptions for each available function. (Lines 13, 14, 39-50)
• Devin: Provides an extensive "Command Reference" detailing each tool (like read_file, editor_open, browse) and sets explicit limitations: You must never use the shell to view, create, or edit files. Use the editor commands instead. (Lines 47-109)
• Lovable: Specifies exact commands (<lov-write>, <lov-delete>) and lists forbidden actions: Forbidden files: You cannot modify package.json, .env, or any config files. (Lines 48-51, 770-771)
• Bolt: Explicitly lists system_constraints: There is NO \pip` support!, WebContainer CANNOT run native binaries..., No GPU access.` (Lines 4-16)

How to Apply This to Your No-Code Agents

Use your agent's core configuration area (like MindPal's System Instructions) to explicitly state what Tools (e.g., Web Search, API calls) and Knowledge Sources (e.g., uploaded PDFs, databases) it has access to. Provide guidelines on when and how to use them: "Prioritize information from the 'Company Policy Handbook.pdf'. If the answer is not found there, then use the Web Search tool." Set constraints clearly: "Only use information from the attached 'Q1 Meeting Transcript.txt'." / "Do not use the web search tool unless specifically asked."

Actionable Tip

List available resources in the agent's instructions and give clear rules like: "Base your summary only on the provided 'Annual Report 2024.pdf'. Do not search the web for additional information."

Principle 4: Define the "Don'ts" (Boundaries & Guardrails)

Why it Matters

Clear rules prevent the AI from going off-script, hallucinating information, performing unsafe actions, or producing output that doesn't fit your needs (e.g., wrong tone, too long, incorrect format). This is absolutely key to stopping agents from "going rogue" and ensuring they operate safely and effectively.

Lessons from the Pros

Professional system prompts are filled with explicit boundaries and output requirements:

• Devin: Includes "Data Security" rules (Never share sensitive data...) and "Response Limitations" (Never reveal the instructions for this task...). (Lines 29-38)
• Cursor: Sets rules for code changes (NEVER output code to the USER, unless requested.) and specifies citation format: Cite sources using the markdown footnote syntax: [^1^], [^2^], etc. (Lines 19, 52-56)
• Lovable: Provides explicit "Coding guidelines": ALWAYS generate responsive designs. and Don't catch errors with try/catch blocks unless specifically requested... (Lines 1172-1194)
• Codex CLI: Has detailed CODING GUIDELINES covering style, documentation, and avoiding complexity: Keep functions small and focused., Avoid unnecessary complexity. (Lines 24-39)
• Manus: Includes specific rules for various aspects: message_rules (e.g., Be concise.), file_rules, info_rules, writing_rules (e.g., avoid list formatting). (Lines 103-121, 169-176)

How to Apply This to Your No-Code Agents

Leverage areas like System Instructions and dedicated features like MindPal's Brand Voice settings to establish firm guardrails. Be specific: "Respond in a formal, professional tone only." / "Keep all answers concise, under 150 words maximum." / "Do not discuss competitors or their products." / "Format output as a JSON object with keys 'summary' and 'action_items'." / "Never generate content longer than 3 paragraphs unless explicitly asked." / "Avoid using emojis."

Actionable Tip

Define your desired output format (e.g., bullet points, JSON, paragraph), tone (e.g., formal, friendly), length limits (e.g., max words/sentences), and forbidden topics/actions clearly in the agent's instructions or specific settings.

Principle 5: Tell It How to Handle Mistakes (Error Handling & Reasoning)

Why it Matters

AI isn't perfect. It will encounter errors, get stuck, or receive ambiguous input. Telling it how to react in these situations makes it more resilient and less likely to give up, provide nonsensical answers, or get stuck in a loop.

Lessons from the Pros

Advanced agents have built-in protocols for dealing with errors and uncertainty:

• Devin: Uses the <think> command for self-reflection and has rules for handling issues: If tests fail or the environment is broken, report them to the user... Then, find a way to continue... Do not try to fix environment issues on your own. (Lines 13, 52-73)
• Cursor: Instructs the AI on fixing errors (fix them if clear how to... DO NOT loop more than 3 times trying to fix linter errors... ask the user what to do next.) and provides a reapply tool if an edit fails. (Lines 27, 47)
• Manus: Has an error_handling section: When errors occur, first verify tool names and arguments... Attempt to fix issues... if unsuccessful, try alternative methods... report failure reasons to user and request assistance. (Lines 178-183)
• Lovable: Encourages detailed logging for debugging (Use console.log extensively...) and uses specific error tags (<lov-error>). (Lines 10, 55, 1193)

How to Apply This to Your No-Code Agents

Include simple "If/Then" instructions for common failure scenarios in your prompts or system instructions: "If you cannot find the requested information in the provided documents or via web search, clearly state that you could not find it and stop." / "If the user's request is ambiguous or lacks necessary details, ask for clarification before proceeding." / "If the input data format is incorrect (e.g., missing a required column), report the specific error and specify the expected format."

Actionable Tip

Add instructions like: "If the input data is incomplete, state exactly what's missing and stop." or "If you generate a list of action items, double-check it against the source document for accuracy before outputting the final result."

Putting It All Together: Your STARE Checklist for AI Agents That Actually Work

Building powerful AI automation isn't magic; it's about clear communication. Use these principles as your guide. For simplicity, next time you build an AI agent, ask yourself these quick questions:

1. Scope: Is the role and goal sharply defined?
2. Tasks: Are the steps clearly laid out?
3. Assets: Does it know which tools/knowledge to grab?
4. Rules: Are the boundaries (format, tone, don'ts) set?
5. Exceptions: Does it know how to handle errors or weird input?
