AI Subscribers: Tokens Left Before Your Monthly Reset? 5 Ways to Use Them Up! 🚀

Every time your subscription (e.g. Claude Pro/Team, an OpenAI account) is about to hit its reset cycle and you still have usage / limit left, doesn’t it feel like such a waste? 😂
Right before a reset is absolutely the best time to do the “super high token consumption, normally too costly to try” big jobs! Here are 5 “clear the stock” tricks to help you squeeze out the last drop of tokens:
1️⃣ 🧪 Generate a full set of Unit Tests / E2E Tests in one go (the king of token burning)
Normally afraid of hitting your limit, so you never ask it to write a full test suite? Before the reset, throw your most complex module at it:
💡 Prompt / Command:
“For all the files in the ./src/services/ folder, write a complete set of unit tests with Jest/Vitest, covering edge cases, error handling and mock APIs, and raise code coverage to over 80%!“
2️⃣ 🧹 Project-wide Refactoring & Type Safety upgrade
Have the AI agent scan the whole codebase for deep refactoring or fill in missing TypeScript types:
💡 Prompt / Command:
“Review the TypeScript codebase of the whole project, replace every any with a precise Type / Interface, find potential memory leaks, duplicated logic (DRY principle) and performance bottlenecks, and give concrete refactoring suggestions.”
3️⃣ 📚 Auto-complete the full API / project documentation
Too lazy to write docs? Let OpenCode / Claude Code read through the project and write the README and JSDoc automatically:
💡 Prompt / Command:
“Read the architecture of the whole project and generate a complete README.md (including an architecture diagram, setup steps and a list of environment variables), and add full JSDoc / TSDoc to all core functions.”
4️⃣ 🛡️ Security Audit & Vulnerability Scan (a thorough sweep for security holes)
Use the large context window to run a full code security review of your system:
💡 Prompt / Command:
“Audit our backend code and check for OWASP Top 10 vulnerabilities (such as SQL injection, XSS, unsanitized inputs, CSRF, authentication flaws), and provide patch examples.”
5️⃣ 🔀 Legacy code migration experiments
Hand an old codebase (e.g. Vue 2 to Vue 3, Options API to Composition API, or JS to TS) to the agent for a large-scale conversion:
💡 Prompt / Command:
“Convert all the Node.js CommonJS code under the ./legacy directory to ES Modules (ESM), and upgrade to the latest package async/await style.”
