Copy-paste, no signup, no email. Five of the 30 prompts from the 50p Power Prompts pack — the same exact text, just fewer of them.
These work in Claude Code (CLI), the VS Code / JetBrains extension, and claude.ai. Replace anything in [BRACKETS] with your context, then paste the relevant file or diff right after the prompt.
Review this file for security vulnerabilities, focusing on OWASP Top 10. List each issue with severity (critical/high/medium/low), the exact line number, why it's dangerous, and a concrete fix.TIP: Works best on auth, payment, and data-handling code. Paste the file content immediately after the prompt.
Given this stack trace, trace the execution path that produced it. For each frame: which file/function, what state would cause it to throw, and the 3 most likely root causes ranked by probability. End with one diagnostic command I can run to confirm the top cause.TIP: Use when you have a stack trace but no working theory yet.
Look at this code and our current test coverage. Identify the 20% of code most likely to cause production bugs (high complexity, weak tests, recent changes, business-critical paths). For each, give me one specific test I could add right now that would meaningfully reduce risk.TIP: Best after a big merge. Surfaces gaps your coverage % hides.
I want to add [FEATURE] to this codebase. Propose three implementation approaches. For each: a one-paragraph description, the files that change, complexity 1-5, risk 1-5, and one downside the others don't have. Force at least one non-obvious option - not just incremental variations.TIP: The forced 'one non-obvious option' is the gold here. Use before any non-trivial feature.
Rewrite this README's first 5 lines so a developer scanning it for 5 seconds either commits to using the tool or leaves. Then rewrite the 'getting started' section so a working example is visible within 30 seconds of arrival. Show me before/after.TIP: Use on any project README older than 6 months.
The full pack: 30 prompts across 6 categories — review, debug, test, architect, docs, devops. 8-page PDF, with a TIP box per prompt telling you exactly when to reach for it.

Get the full 30 — 50p →Or pay what you can from £1. Same PDF. Different price.
The 5 above are CC0 — yours to keep. The other 25 sit behind a 50p paywall for one reason: it makes us treat the PDF as a product. Free PDFs go stale; paid ones get updated. The 50p keeps us honest.
If 50p is the wrong number for you, the pay-what-you-can option starts at 30p — same PDF. If even that does not fit, the 5 above are genuinely complete prompts that work on their own. No hidden lock.
These five span four of the six categories in the pack — security review, debugging, testing, architecture, and docs. The other 25 go deeper in each category plus add DevOps (Dockerfile hardening, CI/CD review, Terraform plan auditing). The five above are the ones we use ourselves most.
Open a CLAUDE.md file at your project root and paste in the prompts you use most. Claude Code reads CLAUDE.md automatically — you'll never need to re-paste them. (The full pack has a whole section on CLAUDE.md patterns that go beyond just dumping prompts.)
