For trivial tasks, use judgment.\n\n## When to Apply\n\n- **Classification**: quick-win, feature, architecture-change, hotfix\n- **Phase**: /plan (assumption surfacing), /implement (simplicity + surgical), /review (scope audit)\n- **Trigger**: All non-trivial coding tasks — this is a behavioral baseline, not a domain skill\n\n## 1. Think Before Coding\n\n**Don't assume. Don't hide confusion. Surface tradeoffs.**\n\nBefore implementing:\n- State your assumptions explicitly. If uncertain, ask.\n- If multiple interpretations exist, present them — don't pick silently.\n- If a simpler approach exists, say so. Push back when warranted.\n- If something is unclear, stop. Name what's confusing. Ask.\n\n## 2. Simplicity First\n\n**Minimum code that solves the problem. Nothing speculative.**\n\n- No features beyond what was asked.\n- No abstractions for single-use code.\n- No \"flexibility\" or \"configurability\" that wasn't requested.\n- No error handling for impossible scenarios.\n- If you write 200 lines and it could be 50, rewrite it.\n\nSelf-check: \"Would a senior engineer say this is overcomplicated?\" If yes, simplify.\n\n## 3. Surgical Changes\n\n**Touch only what you must. Clean up only your own mess.**\n\nWhen editing existing code:\n- Don't \"improve\" adjacent code, comments, or formatting.\n- Don't refactor things that aren't broken.\n- Match existing style, even if you'd do it differently.\n- If you notice unrelated dead code, mention it — don't delete it.\n\nWhen your changes create orphans:\n- Remove imports/variables/functions that YOUR changes made unused.\n- Don't remove pre-existing dead code unless asked.\n\nThe test: **Every changed line should trace directly to the user's request.**\n\n## 4. Goal-Driven Execution\n\n**Define success criteria. Loop until verified.**\n\nTransform tasks into verifiable goals:\n- \"Add validation\" → \"Write tests for invalid inputs, then make them pass\"\n- \"Fix the bug\" → \"Write a test that reproduces it, then make it pass\"\n- \"Refactor X\" → \"Ensure tests pass before and after\"\n\nFor multi-step tasks, state a brief plan:\n```\n1. [Step] → verify: [check]\n2. [Step] → verify: [check]\n3. [Step] → verify: [check]\n```\n\nStrong success criteria let you loop independently. Weak criteria (\"make it work\") require constant clarification.\n\n## Checklist\n\nDuring /plan:\n- [ ] Assumptions stated explicitly before proposing solution\n- [ ] Ambiguities surfaced — multiple interpretations presented if they exist\n- [ ] Simplest viable approach chosen (justify if not the simplest)\n\nDuring /implement:\n- [ ] No features beyond what was asked\n- [ ] No abstractions for single-use code\n- [ ] Every changed line traces to the user's request\n- [ ] Pre-existing code left alone unless directly required\n- [ ] Success criteria defined before implementation begins\n\nDuring /review:\n- [ ] Diff contains only requested changes — no drive-by refactoring\n- [ ] Code is not overcomplicated — could a simpler version work?\n- [ ] Orphaned imports/variables from THIS change are cleaned up\n- [ ] Pre-existing dead code mentioned but not deleted\n\n## Code Simplification Checklist\n\nWhen reviewing or refactoring, apply Chesterton's Fence — understand WHY before removing:\n\n- [ ] Deep nesting (>3 levels) → extract to named functions\n- [ ] Long functions (>50 lines) → split by responsibility\n- [ ] Poor naming → rename to reveal intent\n- [ ] Speculative abstractions → remove if only one caller exists\n- [ ] Duplicate logic → extract only if 3+ occurrences (not 2)\n\n**Simplification rules:**\n- Preserve behavior exactly — simplification is NOT a feature change\n- Fewer lines is not always simpler — a 1-line nested ternary is worse than a 5-line if/else\n- Separate simplification commits from feature commits — never mix\n\n## Heading-Scoped Read Note\n\nFor phase-entry loading, read only:\n- `When to Apply`\n- `Checklist`\n- `Code Simplification Checklist`\n\nLoad numbered principle sections (`## 1`–`## 4`), `Common Rationalizations`, `Anti-Patterns`, and `References` on full read or cache miss only.\n\n## Common Rationalizations\n\n| Rationalization | Reality |\n|---|---|\n| \"It works, that's good enough\" | Working code that's unreadable or architecturally wrong creates debt that compounds. |\n| \"We'll clean it up later\" | Later never comes. The current phase is the quality gate — use it. |\n| \"I'm confident about this approach\" | Confidence is not evidence. State your assumptions explicitly or verify against docs. |\n| \"This abstraction might be useful later\" | Don't preserve speculative abstractions. If there's only one caller, inline it. |\n| \"I'll just quickly improve this unrelated code too\" | Unscoped changes create noisy diffs and obscure the actual intent. Touch only what you must. |\n| \"The tests pass, so it's good\" | Tests are necessary but not sufficient. They don't catch architecture problems, security issues, or readability. |\n\n## Anti-Patterns\n\n- **Silent assumption**: Picking one interpretation without surfacing alternatives\n- **Speculative flexibility**: Adding config/abstraction layers \"for the future\"\n- **Drive-by cleanup**: \"Improving\" adjacent code that wasn't part of the request\n- **Vague completion**: Claiming \"done\" without verifiable success criteria\n- **Rationalizing shortcuts**: Using plausible-sounding excuses to skip verification steps\n\n## References\n\n- Source: [multica-ai/andrej-karpathy-skills](https://github.com/multica-ai/andrej-karpathy-skills) (MIT declared upstream; no root LICENSE artifact; provenance asserted)\n- Simplification enrichment: [addyosmani/agent-skills — code-simplification](https://github.com/addyosmani/agent-skills) (MIT)\n- Complements: `writing-plans` (Think Before Coding), `verification-before-completion` (Goal-Driven Execution)\n- Guardrails: `.agent/rules/engineering_guardrails.md` §7 Scope Discipline\n","tagline":"Behavioral guidelines to reduce common LLM coding mistakes — Think Before Coding, Simplicity First, Surgical Changes, Goal-Driven Execution.","category":"design-creative","tags":["agent-skill"],"author":"KbWen","verified":false,"attribution":{"status":"registry_indexed","statusLabel":"Registry indexed","shortLabel":"REGISTRY INDEXED","sourceLabel":"github fast track","sourceDetail":"KbWen/agentic-os","creatorName":"KbWen","creatorUrl":"https://github.com/KbWen","sourceUrl":"https://github.com/KbWen/agentic-os/tree/main/.agents/skills/karpathy-principles","indexedBy":"OpenAgentSkill community index","claimUrl":"https://www.openagentskill.com/skills/kbwen-karpathy-principles#claim-this-skill","claimCta":"Claim this skill","trustNote":"This listing was indexed from public sources and is not marked official until a maintainer claim is approved.","publicNote":"Attribution links to the public repository or creator profile.
