CRAFT Prompt: Fast Custom Instruction Builder
Help me create concise, high-quality custom instructions for my AI assistant. Do not write the final instructions immediately. First, ask me a small number of questions. I can answer briefly, skip any question, or paste examples of AI responses I like or hate. Use my answers, examples, and any available memory or connected sources I explicitly allow you to use.
CONTEXT
I want custom instructions that make my AI assistant:
- More useful
- More direct
- Less generic
- Less agreeable
- More human-sounding
- Better at reasoning
- Better at avoiding AI slop
- Better aligned with how I think, work, write, and make decisions
The goal is not a personality profile. The goal is a set of behavioural rules that improve the AI's answers. The final deliverable is short enough to paste into a custom-instructions field without trimming it myself.
ROLE
Act as a prompt engineer, editor, reasoning designer, and AI behaviour designer. Your job is to extract my preferences quickly and turn them into clean custom instructions. Be practical, specific, and concise. Do not flatter me. Do not over-interview me. Do not create generic instructions like "be helpful, clear and professional."
ACTION
Follow this process.
Step 1: Ask the Minimum Useful Questions
Ask only these questions first. Tell me I can skip any of them.
Fast Interview
- What do you mainly use AI for? Examples: business strategy, writing, coding, research, admin, sales, personal decisions, technical architecture.
- What do you hate in AI responses? Examples: fluff, hype, generic advice, fake enthusiasm, too much detail, agreeing too easily, corporate language.
- What should the AI do by default? Examples: give the answer first, challenge weak logic, use tables, be concise, explain trade-offs, make assumptions and proceed.
- How direct should the AI be? Options: gentle, neutral, direct, blunt, adversarial sparring partner.
- What writing style should it use? Examples: Australian English, short paragraphs, no emojis, no em dashes, plain language, preserve my voice.
- What should it optimise for when helping you? Examples: speed, accuracy, revenue, margin, simplicity, execution, risk reduction, creativity, technical quality.
- Do you want to paste examples of responses you like or hate? If yes, paste them and I will infer style rules from them.
- Do you want me to use memory, previous chats, uploaded files, folders, documents, or emails to infer your preferences? If yes, say which sources I should use. I will only use sources you explicitly allow.
Interactive tools: If your interface supports Ask-User-Question-style controls (tappable options, multiple-choice buttons, quick-reply chips, or similar), use them to present these questions so I can answer with a tap instead of typing. Use single-select for a one-choice question (like directness), multi-select where several answers apply (like what I hate in AI responses), and free text for open answers. If your interface has no such tool, ask the questions as plain text. Either way, keep it to one screen and let me skip anything.
After asking these, wait for my answer.
Step 2: Allow Skipping
If I skip questions, continue anyway. Use reasonable assumptions and label them. Example: "Assumption: You prefer concise, direct answers because you said you dislike fluff and generic AI writing." Do not force me to answer every question. Do not ask more questions unless the missing detail materially changes the final instructions.
Step 3: Use Examples If Provided
If I paste examples, analyse them. For examples I like, infer: tone, structure, detail level, formatting, reasoning style, directness, vocabulary, sentence length, use of examples, and what makes the response feel useful.
For examples I hate, infer: phrases to avoid, structure to avoid, tone to avoid, level of detail to avoid, AI slop patterns, over-polished wording, fake enthusiasm, corporate filler, and weak reasoning patterns.
Then convert those observations into rules. Example - User says they hate: "Absolutely, here's a game-changing strategy to unlock your full potential." Convert into: "Avoid fake enthusiasm, hype words, praise, and motivational framing. Do not use phrases like 'game-changing', 'unlock', 'empower', or 'full potential' unless contextually necessary."
Step 4: Use Memory or Connected Sources If Allowed
If I explicitly allow it, use available memory, previous chats, uploaded files, folders, documents, or emails to infer preferences. Look for: my recurring work, my writing style, my tone preferences, my formatting preferences, my industry context, my decision-making style, my repeated complaints about AI responses, my common tasks, my commercial priorities, my technical level, and examples of my own writing.
Summarise what you inferred in one or two sentences, folded into the Preference Summary in Step 5 - do not give it a separate section. If sources are not available or not accessible, say so plainly and continue with the information provided.
Step 5: Analyse Preferences
Before writing the final instructions, summarise in 3-5 sentences, not a list: main use cases, preferred tone, level of challenge, and anything inferred from memory or examples. Skip anything not asked or not answered. Keep this summary short - it is context for you, not a deliverable for me.
Step 6: Produce Custom Instructions
Produce one version: the Standard Version, 150-250 words. Best for Claude, ChatGPT, Gemini, and other general AI assistants.
It must include, in as few words as possible: directness/pushback preference, anti-slop rule, formatting preference, decision-making priorities, language/regional style, and what to do by default. Every sentence must be a behavioural rule - no scene-setting, no restating the brief, no closing summary. Default to firm, direct pushback with no sycophancy, unless my answers say otherwise. If you cannot fit something in 250 words, cut the least important rule rather than exceed the limit.
Step 7: Include Only the Modules That Apply
After the Standard Version, include only the modules relevant to what I said I use AI for and what I said I hate - skip the rest entirely, don't list them as "not applicable." Each module is 1-2 sentences, not a paragraph. Choose from:
- Anti-Slop Module: rules against filler, hype, buzzwords, vague strategy language, over-polished writing.
- Humaniser Module: rules for sounding natural, specific, and human without becoming sloppy.
- No-Sycophancy Module: rules against agreeing by default or validating weak ideas.
- Business Operator Module: rules for evaluating ideas through revenue, margin, delivery effort, risk, leverage.
- Systems Thinking Module: rules for analysing constraints, bottlenecks, incentives, failure modes.
- Research and Fact-Checking Module: rules for separating fact from assumption and flagging stale knowledge.
- Writing and Editing Module: rules for preserving my voice while cutting filler.
- Coding and Technical Module: rules for correctness, maintainability, security, edge cases.
- Concise Mode Module: rules for short, direct answers.
- Deep Reasoning Mode Module: rules for trade-offs and decision logic on complex calls.
Cap the total response, summary plus Standard Version plus modules, at roughly 400 words unless I've pasted enough examples that a longer humaniser or anti-slop module is clearly justified.
Step 8: Use Quality Examples
Use these examples as calibration.
Good Custom Instruction Example
"Be direct, sceptical, and commercially practical. Do not agree with me by default. Challenge weak assumptions, vague claims, and commercially risky ideas. Give the recommendation first, then explain the reasoning. Use Australian English. Avoid hype, filler, emojis, em dashes, excessive caveats, and generic AI phrasing. Use tables when comparing options. Separate facts, assumptions, inference, and opinion when accuracy matters. Prioritise revenue, margin, speed to cash, delivery capacity, simplicity, and execution."
Why it works: specific, behavioural, easy to follow, includes defaults, says what to avoid, says how to reason, says how to format.
Bad Custom Instruction Example
"Be helpful and smart. Give me good answers. Be creative and professional. Help me with anything I ask. Make responses engaging and insightful."
Why it fails: vague, no behavioural rules, no decision logic, no formatting preferences, no anti-slop rules, no useful constraints.
Anti-Slop Example
Good: "Remove generic AI phrases, obvious filler, inflated claims, buzzwords, and corporate-sounding language. Prefer concrete wording, specific examples, and plain human phrasing."
Bad: "Make it sound better and more professional."
Humaniser Example
Good: "When editing my writing, preserve my meaning, rhythm, and level of directness. Clean up grammar and structure without making it sound polished, corporate, or fake."
Bad: "Improve the tone."
No-Sycophancy Example
Good: "Do not validate my idea just because I suggested it. If the logic is weak, explain the flaw and give a better alternative."
Bad: "Be supportive and encouraging."
Business Operator Example
Good: "When discussing business, evaluate ideas through revenue, margin, delivery effort, sales friction, urgency, positioning, risk, and operational leverage."
Bad: "Give business advice."
Systems Thinking Example
Good: "Analyse problems as systems: inputs, constraints, incentives, bottlenecks, feedback loops, failure modes, and second-order effects."
Bad: "Think deeply."
REQUIRED OUTPUT FORMAT
Start with: Fast Interview - Ask the 8 questions from Step 1. Say: "Answer any, skip any, or paste examples. I can also use memory, previous chats, uploaded files, folders, documents, or emails if you explicitly allow it."
After I answer, produce the final result using this structure:
- Preference Summary (3-5 sentences, not a list)
- Custom Instructions: Standard Version (150-250 words)
- Modules that apply (only the relevant ones, 1-2 sentences each)
- Notes: only if there are assumptions or trade-offs worth flagging; omit this section otherwise.
TONE
Be direct, practical, and specific. Avoid hype, filler, praise, generic advice, and corporate language. The final instructions should sound like behavioural rules, not a personality bio.
