The prompts cover code explanation, debugging, test generation, refactoring, code review, documentation, and commit messages, each with structured slots for specific inputs.", "body_md": "I tracked every AI prompt I used for 30 days straight. Most were throwaway. But **seven of them came back over and over** — and together they save me at least 10 hours a week.\n\nThese aren't \"act as a senior developer\" fluff. They're specific, structured prompts with slots you fill in. Copy them, paste them, edit the `[bracketed]`\n\nparts.\n\nLet's go.\n\nWe all inherit code we didn't write. Instead of tracing through 300 lines line-by-line:\n\n```\nExplain what this code does, step by step. Focus on:\n1. The overall purpose\n2. The data flow (inputs → transformations → outputs)\n3. Any side effects or external calls\n4. Edge cases it handles (or misses)\n\nCode:\n[paste code here]\n```\n\n**Why it works:** You're forcing a structured breakdown instead of a rambling summary. The \"edge cases it misses\" line alone catches bugs you'd otherwise find in production.\n\nStop pasting error messages and hoping. Give the model the *context* it needs:\n\n```\nI'm getting this error:\n\n[paste error + stack trace]\n\nHere's the relevant code:\n\n[paste code]\n\nWhat I expected: [describe expected behavior]\nWhat I tried already: [list attempts]\n\nWalk me through the most likely root causes, ranked by probability.\nFor the top cause, give me the smallest fix that doesn't break other things.\n```\n\n**Why it works:** Ranking by probability stops the model from leading you down rabbit holes. \"Smallest fix\" prevents it from rewriting your whole function.\n\nWriting tests is the most-skipped part of development. Make it frictionless:\n\n```\nWrite unit tests for this function using [pytest / Jest / your framework].\nCover:\n- The happy path\n- Empty/null/zero inputs\n- Boundary values\n- One error/exception case\n\nUse table-driven tests where it makes sense.\nDon't mock anything unless absolutely necessary.\n\nFunction:\n[paste function]\n```\n\n**Why it works:** The constraint \"don't mock unless necessary\" keeps tests meaningful — over-mocked tests give false confidence. Table-driven tests keep the output compact and readable.\n\n```\nRefactor this code for readability and maintainability, WITHOUT changing behavior.\nConstraints:\n- Keep the same public API / function signatures\n- Preserve all existing behavior\n- Prioritize clarity over cleverness\n\nThen tell me:\n1. What you changed and why\n2. What you intentionally left alone\n\nCode:\n[paste code]\n```\n\n**Why it works:** \"Tell me what you left alone\" is the secret. It stops over-refactoring and forces the model to justify each change — so you can sanity-check it.\n\nBefore you open a PR, review your own diff:\n\n```\nReview this code change as a thorough senior engineer. Check for:\n- Logic bugs or race conditions\n- Security issues (injection, auth, secrets)\n- Performance gotchas (N+1 queries, unnecessary allocations)\n- Missing error handling\n- Anything that would block this in a real PR\n\nBe specific. Cite line numbers. Rate severity (critical / major / minor).\n\nDiff:\n[paste diff or code]\n```\n\n**Why it works:** Self-review catches the obvious stuff before a human reviewer sees it — which means faster merge times and fewer review round-trips.\n\n```\nTurn this function/module into clean developer documentation.\nInclude:\n- A one-line summary\n- A \"Parameters\" table (name, type, description)\n- A \"Returns\" section\n- A minimal usage example\n- 1-2 gotchas if relevant\n\nKeep it under 150 words. No marketing language.\n\nCode:\n[paste code]\n```\n\n**Why it works:** Documentation nobody writes is documentation nobody reads. A 150-word cap keeps it tight enough that it actually gets merged.\n\n```\nWrite a conventional commit message for this diff.\nFormat: <type>(<scope>): <subject>\n\nTypes: feat, fix, refactor, docs, test, chore, perf\nRules:\n- Subject line under 50 chars, imperative mood\n- Add a body ONLY if the \"why\" isn't obvious\n- No fluff, no \"updated code\"\n\nDiff:\n[paste diff]\n```\n\n**Why it works:** Consistent commit history makes `git log`\n\nand `git blame`\n\nactually useful. This takes 5 seconds and pays off forever.\n\nHaving the prompts is step one. The real productivity gain comes from **keeping them one keystroke away**:\n\n`User Snippets`\n\n, JetBrains Live Templates). Type `bugprompt`\n\n, hit Tab, done.If you want a jumpstart, I put together\n\n10 of my most-used prompts as a free downloadable pack— formatted, categorized, and ready to paste into your snippet tool:👉\n\n[10 AI Prompts That Save Me 5 Hours Every Week — Free](Just enter your email — it's the free one. If you want the full 330-prompt library covering coding, writing, marketing, and automation, that's here:\n\n[AI Prompt Master Library].)\n\nThe productivity win isn't from any single prompt. It's from **removing friction** — turning a 3-minute \"how do I phrase this?\" into a 3-second paste.\n\nStart with one. I'd pick the bug-hunting prompt (#2). Track how much time it saves you this week. Then add another.\n\nThe compounding is real. Ten hours a week is 500+ hours a year. That's a side project, a certification, or just... your evenings back.\n\n*What's the one AI prompt you use every day?
