GPT-Prompt-Hub is a community repository that collects and refines structured prompts for large language models such as Claude, GPT, and Gemini. It is for engineers, founders, researchers, students, marketers, and other people using AI for coding, writing, planning, and analysis. The catalogue instruction is one example of the repository’s prompt resources.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.01312 | $0.01312 |
| Opus 5 | $0.00656 | $0.00656 |
| Sonnet 5 | $0.00262 | $0.00262 |
| Haiku 4.5 | $0.00131 | $0.00131 |
Grade A, and why
GPT-Prompt-Hub CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Repository Structure
This repo is a curated hub of 222 prompts for Claude/GPT/Gemini, organized under prompts/ by category:
prompts/business/(25) — strategy, PRDs, venture plans, unit economicsprompts/career/(15) — resume, cover letter, ATS, interview prepprompts/creative/(25) — music, visual, games, multimediaprompts/engineering/(25) — code review, architecture, simulatorsprompts/health-life/(7) — CBT, clinical reasoning, wellness (non-diagnostic)prompts/learning/(25) — tutoring, language coaching, mock interviewsprompts/marketing-seo/(25) — paid media, SEO, landing pages, brandprompts/productivity/(25) — PRDs, planning, PR review, app specsprompts/research/(25) — literature review, market analysis, paper readingprompts/writing/(25) — editing, translation, long-form, screenplayprompts/legacy/(4) — original 2024 custom GPTs, kept for historical record
Each prompt file uses frontmatter (title, category, tags, model, use_case) and a structured body (Role / Objective / Inputs / Output / Constraints / Example). Do not edit prompts without updating frontmatter. Root README.md is the source of truth for the full catalog; each category has its own README.md as a per-folder TOC.
_analysis/popular-patterns.md holds the strategy analysis behind the 222-prompt curation — read before adding new prompts.
Development Guidelines
Philosophy
Core Beliefs
- Incremental progress over big bangs - Small changes that compile and pass tests
- Learning from existing code - Study and plan before implementing
- Pragmatic over dogmatic - Adapt to project reality
- Clear intent over clever code - Be boring and obvious
Simplicity Means
- Single responsibility per function/class
- Avoid premature abstractions
- No clever tricks - choose the boring solution
- If you need to explain it, it's too complex
Process
1. Planning & Staging

What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

GPT-Prompt-Hub CLAUDE.md is an instructions file published in the GitHub repository LichAmnesia/GPT-Prompt-Hub (2,394 stars, last pushed 4mo ago), licensed MIT. It adds 1,312 tokens to every session, about $0.0066 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
