(2) user says "this error means", "why is this broken", "what's the fix", or "how to resolve this error". (3) user pastes a bug description and asks for root cause analysis and solution. ## Core Position This skill solves the specific problem of: *an error message is cryptic — the user needs a plain-language explanation of what went wrong and how to fix it.* This skill IS NOT: - A code rewrite tool — it explains and suggests fixes, does not rewrite entire files - A debugging environment — it analyzes reported errors, does not run code - A deployment tool — it does not fix production issues, only advises This skill IS activated ONLY when: an error message or stack trace + explanation/fix intent are both present. ## Modes ### `/error-to-fix` **Default mode.** Analyzes the error and provides explanation, root cause, and fix suggestions. When to use: User pastes an error and wants to understand and resolve it. ### `/error-to-fix/root-cause` Focuses on the underlying system-level cause, not just the immediate symptom. When to use: User wants deeper understanding beyond the surface-level fix. ### `/error-to-fix/prevent` Suggests patterns and practices to prevent this error from recurring. When to use: User is in a review or learning context and wants to avoid the error long-term. ## Execution Steps ### Step 1 — Parse the Error 1. Receive error input (pasted text, stack trace, screenshot text) 2. Detect error type: - **SyntaxError**: Python/JavaScript parse failure — usually a typo or missing token - **RuntimeError/Exception**: code ran but crashed — check types, imports, null refs - **ImportError / ModuleNotFoundError**: missing or misnamed dependency - **ConnectionError / Timeout**: network, database, or API connectivity issue - **PermissionError / AccessDenied**: file or resource permission problem - **AssertionError / Test failure**: behavior mismatch against expected result - **Custom error**: non-standard error from user code or library 3. Extract key identifiers from the error: - Error type name (first word in traceback or error class) - File path and line number (where error originated) - Variable/state values at the point of failure - Version information if present (library versions, Python/Node version) ### Step 2 — Identify Root Cause For each identified error type: | Error Type | Common Root Cause | Quick Diagnostic | |---|---|---| | SyntaxError | Missing `)`, `:`, or `}` | Check line number and surrounding lines | | ModuleNotFoundError | Typo in import, missing package | `pip install` / `npm install` | | TypeError | Wrong type passed to function | Check the actual type vs. expected type | | ReferenceError | Variable used before assignment | Check variable initialization | | ConnectionError | Wrong URL, firewall, service down | Verify URL and network access | | ImportError | Circular import, wrong path | Check `__init__.py` and import order | | ValueError | Invalid argument value | Check the value against allowed range | | KeyError | Missing dict key | Check if key exists before access | ### Step 3 — Deliver Explanation Structure each response as: 1. **What happened** (one sentence): plain-language description of the error 2. **Why it happened**: root cause — what the error is actually telling you 3. **How to fix**: specific, actionable steps with code before/after if applicable 4. **How to prevent**: one practice or pattern to avoid this error in the future ### Step 4 — Validate - Error type is correctly identified - Root cause is specific, not generic ("something is wrong") - Fix applies to the exact error — not a similar but different error - No code changes that contradict or undo the user's existing code ## Mandatory Rules ### Do not - Do not guess at the root cause if the error message is unambiguous — use what the error says - Do not provide fixes that require installing packages or modifying files the user hasn't mentioned - Do not change the user's code logic beyond the minimal fix - Do not dismiss the error as "not a problem" without explaining it ### Do - Quote the specific error message in your explanation - Provide a minimal, targeted fix — not a rewrite of the entire file - Distinguish between quick fixes and proper architectural solutions - Ask for the relevant code snippet when the error alone is insufficient to diagnose ## Quality Bar **A good output:** - Error type is correctly identified and named - Root cause is specific and explains why the error occurred in this context - Fix is minimal and directly addresses the cause - Prevention tip is actionable and relevant to the error type **A bad output:** - "Something went wrong" as the explanation - Fix requires changing unrelated parts of the codebase - Root cause contradicts what the error message states - Provides 5 different possible causes when the error is unambiguous ## Good vs. Bad Examples | Scenario | Bad Output | Good Output | |---|---|---| | Python TypeError | "Type error occurred" | "TypeError: list.append expects str, got int — add `str()` cast around the input" | | Node ModuleNotFoundError | "Module is missing" | "ModuleNotFoundError: 'requests' not in requirements.txt — run `pip install requests`" | | React undefined is not an object | "Something is undefined" | "The error means `props.user.address` is accessed before `user` is set. Add a guard: `props.user?.address`" | | Connection refused | "Network is down" | "ECONNREFUSED: server at localhost:5432 is not accepting connections. Is PostgreSQL running?" | ## References - `references/` — Error type taxonomy, common stack trace patterns by language, quick-fix cheat sheet
