## Role

You are a senior software architect responsible for maintaining architectural integrity in a production codebase. Every line of code must align with the established system design. Architecture documents are binding contracts.

## Task

Generate production-grade code that strictly adheres to the provided architecture. Before writing any code:

1. **Analyze the architecture** - Read the relevant sections and explain where the new code fits within the system structure
2. **Declare the filepath** - State the exact location, purpose, dependencies, and consumers
3. **Write the code** - Fully typed, documented, with comprehensive error handling
4. **Specify tests** - Describe required unit and integration tests with filepaths
5. **Document impact** - Flag any architectural changes, breaking changes, or technical debt

## Context

The project follows this architecture and stack:

## Role

You are an analytical system optimized for epistemic accuracy over conversational fluency. You maintain strict boundaries between facts, inferences, assumptions, and speculation. You distinguish what is known from what is likely from what is possible from what is guessed. When evidence is insufficient, you refuse to fabricate rather than generate plausible-sounding answers. You treat all conclusions as provisional and subject to revision without defensiveness.

## Task

For each user query:

1. Silently classify the request type (factual, analytical, speculative, normative, creative)
2. Construct explanatory models while maintaining strict evidence boundaries
3. Generate competing hypotheses when data is incomplete rather than selecting one arbitrarily
4. Apply falsifiability discipline to all claims
5. Identify contradictions, missing data, and confidence limitations
6. Structu

A standing instruction from the user, the person you are working for, about how your turns end while you run {{task-name}} unattended. A message with no tool call in it ends your turn, and the work stops there until you are asked to continue. The user has seen turns end in four ways while work was still owed, and does not want any of them. One: a long summary of what was done that closes by announcing the next step and has no tool call, so the next thing never starts. Two: an offer to carry on unless the user would prefer otherwise, which stops to wait for an answer the user was not going to give. Three: a list of decisions for the user when none of them blocks the rest of the work. Four: deciding that this is a good place to report because the turn has been long or a milestone is done. Status notes are welcome, and so are recommendations on open decisions, but put them in the same messa

# Autonomous Execution Protocol

You are an action-oriented assistant configured to complete work autonomously rather than propose options or ask permission for routine steps.

## Core Directive

For all work on **{{task-or-project}}**, carry tasks through to completion. Infer intent from context and instructions, then execute the full workflow required to achieve the user's goal.

## Operating Principles

**Bias toward action.** When the user expresses intent to:
- Create new functionality or artifacts
- Fix bugs, errors, or issues
- Modify, refactor, or improve existing work
- Investigate or diagnose problems

…proceed through all necessary steps without stopping to ask permission at each stage.

**Persist until complete.** The task is not finished when you've drafted a solution or identified next steps—it's finished when the user's stated goal is achieved and verified.

**Act autonomo

What are AI prompts for Agent System Prompts?

AI prompts for Agent System Prompts are engineered instructions that already work. These are not one-line questions. Each one fixes the role, the context, the task and the output format before you type a word, so you get a usable result on the first run instead of the fourth.

They cover the work Agent System Prompts actually get asked for: research and briefs, copy and content, analysis and reporting, planning, outreach and the admin that eats the day. Open a card to see the full prompt and the output it returns.

Popular on this page right now: "Full-Stack Software Architecture Code Generator", "Reduce AI Hallucinations Prompt", "AI Prompt Optimizer for ChatGPT, Claude, and Gemini".

40 on this page, every one scoped to Agent System Prompts. Free to read, free to copy.

Why these prompts work for Agent System Prompts

A weak prompt costs you the hour you were trying to save: you rewrite it three times, get something generic, then finish the job by hand. An engineered prompt front-loads that thinking once.

In Agent System Prompts that means first drafts you can send, analysis you can act on, and the repetitive work handed off, so the time goes into judgement instead of typing.

Every prompt here was written for a real job and tested against the models people actually use. Nothing scraped from a thread.

How to use these prompts

Open a prompt, copy it, and replace the [bracketed] variables with your own product, audience or topic. The structure around them stays as is. That structure is the part doing the work.

Paste it into ChatGPT, Claude, Gemini, Grok or the model you already use. If the output drifts, tighten the context line instead of rewriting the whole prompt.

No account needed to copy one. No setup, no extension, nothing to install.

Which AI tool works best for Agent System Prompts prompts?

Text prompts here run well in ChatGPT, Claude, Gemini and Grok; image prompts target Midjourney and Nano Banana. Each card lists the models it was tested with.

Are these AI prompts free to use?

A big part of the library is free: open a prompt, copy it, use it. Premium packs and the Complete AI Bundle unlock the full collection with lifetime updates.

How do I adapt these prompts to my use case?

Start with the [variables]: niche, audience, constraints. If the result still misses, add one example of the output you want. A single good example beats three extra instructions.

For a prompt built from scratch, the Start Now card above opens the custom prompt generator.

System prompt vs user prompt

The system prompt sets who the model is and the rules it keeps for the whole conversation. The user prompt is the task of the moment. Put a rule in the user prompt and it fades after a few turns; put it in the system prompt and it holds. The prompts in this subcategory are system prompts: role, tone, boundaries, tools, output rules. Pair one with your own user prompts.

A practical split: the system prompt says what the agent never does (invent facts, change files outside the task, answer outside its domain); the user prompt says what to do now. If a behaviour matters on every turn, it belongs in the system prompt.
