--- name: client-troubleshooting-guide-builder description: "Transforms raw log snippets, error descriptions, or API call patterns into a structured client-facing troubleshooting guide with a symptom summary, a ranked list of probable causes, a step-by-step diagnostic flow, resolution steps per cause, escalation criteria, and a copy-paste client reply. Use when building support runbooks, converting a recurring ticket into a reusable guide, or documenting how to diagnose a specific API error, integration failure, or authentication issue." argument-hint: "[error-or-log] [product-area]" allowed-tools: ["Read"] --- # Client Troubleshooting Guide Builder ## Purpose Turn a messy error report — log lines, a stack trace, a client's description, or an odd API call pattern — into a clean, sequenced troubleshooting guide that a support engineer or CSM can run without escalating. Produces a diagnostic decision flow, resolution steps mapped to each probable cause, and a ready-to-send client reply, so recurring issues become reusable runbooks instead of one-off firefights. ## When to Use Invoke this skill when the user asks to: - Build a troubleshooting guide or runbook from an error, log snippet, or stack trace - Turn a recurring support ticket into reusable documentation - Diagnose an API error (4xx/5xx), webhook failure, or authentication/token issue - Document a step-by-step diagnostic flow for a client-facing support team - Create a decision tree for triaging a specific integration or SDK problem - Write a client-facing explanation of what went wrong and how to fix it ## Inputs Required Before starting, collect: - **The error signal**: Log snippet, error message, status code, stack trace, or client's verbatim description - **Product area**: What the client was doing — e.g., authentication, webhooks, rate limits, SDK call, data sync - **Environment details**: Language/SDK, API version, sandbox vs. production, region if relevant - **What the client already tried**: Steps taken, if known - **Access level of the guide's user**: Client-facing (limited access) vs. internal support (dashboard/logs access) - **Known related issues**: Any recurring causes or recent incidents tied to this symptom - **Escalation path**: Who owns L2/engineering escalation and what triggers it If access level or escalation path is missing, default to a client-facing guide and a generic "escalate to L2 with reproduction steps" criterion, and note the assumption. ## Instructions ### Step 1: Symptom Summary Restate the problem in one clear paragraph a non-author could understand. - Extract the **observable symptom** (what the client sees) separately from the **technical signal** (what the log/error says) - Identify the **status code or error class** if present, and translate it into plain language (e.g., `401` → "the request was authenticated incorrectly or the token expired") - Note the **trigger context**: when it happens, how often, and whether it's intermittent or consistent - If the error signal is ambiguous, list the 1–2 clarifying questions that would most narrow the cause ### Step 2: Probable Causes (Ranked by Likelihood) Generate 3–6 probable causes, ordered most-to-least likely for this specific signal. For each cause include: - **Cause name**: Short, specific (e.g., "Expired or malformed bearer token," not "Auth problem") - **Why it fits this signal**: One sentence tying it to the error/log evidence - **Likelihood**: High / Medium / Low, with a one-line reason - **Fastest confirming check**: The single test that proves or rules this cause in Rank by a combination of frequency (how common this cause is for this error class) and evidence match (how well the signal points to it). Put the highest-frequency, best-matched cause first. ### Step 3: Diagnostic Flow (Step-by-Step Decision Tree) Build a sequential yes/no diagnostic flow that isolates the cause in the fewest steps. - Start with the **cheapest, highest-yield check** first (e.g., verify the token isn't expired before inspecting payload structure) - Format each node as: **Check → Expected result → If yes, go to X / If no, go to Y** - Every branch must terminate at either a **confirmed cause** (route to its resolution in Step 4) or an **escalation trigger** (route to Step 5) - Include the exact command, dashboard location, or API call to run at each check where possible (e.g., "Run a test request with `curl -H 'Authorization: Bearer '` and confirm a `200`") - Keep it to 4–8 decision nodes — collapse redundant branches ### Step 4: Resolution Steps (Per Confirmed Cause) For each probable cause from Step 2, provide a numbered fix sequence. - Write steps at the **access level specified** — client-facing guides never instruct actions the client can't perform - Each resolution: numbered steps, the expected outcome after the fix, and a **verification step** confirming the issue is resolved - Include a **rollback or safe-retry note** where a fix could cause side effects (e.g., regenerating an API key invalidates the old one) - Flag any fix that requires a code change vs. a config/dashboard change ### Step 5: Escalation Criteria Define exactly when to stop troubleshooting and escalate. - List 3–5 concrete triggers (e.g., "diagnostic flow terminates with no confirmed cause," "error persists after token regeneration and payload validation," "5xx errors correlate with a platform status incident") - Specify **what to include in the escalation**: reproduction steps, request ID / trace ID, timestamps, environment, and confirmed-ruled-out causes - Name the escalation owner or path from the input (or the default note if not provided) ### Step 6: Client-Ready Reply Write a copy-paste response the support team can send to the client. - Plain, reassuring, no internal jargon or blame - Structure: acknowledge → likely cause in plain terms → 1–3 client-actionable steps → what happens next if that doesn't work - Under 150 words; no bracket placeholders — fill in the specifics from the inputs ## Output Format - **Structure**: Six labeled sections in order; diagnostic flow as an indented decision tree; resolution steps as numbered lists grouped by cause - **Length**: 800–1,200 words - **Format**: Structured document — scannable headers, numbered flows, inline code formatting for commands and error codes - **Sections**: Symptom Summary → Probable Causes (ranked) → Diagnostic Flow → Resolution Steps → Escalation Criteria → Client-Ready Reply - **Tone**: Support engineer writing a runbook — precise, calm, action-first; no filler, no hedging ## Quality Checklist Before delivering output, verify: - [ ] Probable causes are ranked by likelihood with a stated reason — not an unordered list - [ ] Every diagnostic flow branch terminates at either a confirmed cause or an escalation trigger (no dead ends) - [ ] Each resolution set includes a verification step confirming the fix worked - [ ] Resolution steps match the specified access level — client-facing guides contain no admin-only actions - [ ] Escalation criteria are concrete triggers, not "escalate if needed," and specify what to include - [ ] The client-ready reply is under 150 words with zero bracket placeholders ## Notes - Ask for a request ID or trace ID early — it's the single highest-leverage piece of evidence for API issues and it's what engineering will ask for first - For intermittent errors, prioritize causes tied to rate limits, token expiry windows, and eventual-consistency delays before assuming a code bug - The best guides get shorter over time: once a cause proves rare in practice, demote or drop it so the flow stays fast - When the error signal is a raw stack trace, isolate the topmost line originating in the client's own code versus the SDK/platform — that boundary usually points to who owns the fix --- ## How to use this skill This file is a Claude Code skill in [Anthropic's standard format](https://docs.anthropic.com/en/docs/claude-code/skills) — markdown with YAML frontmatter at the top. **Installing in Claude Code:** - `~/.claude/skills//SKILL.md` — auto-loads in every session anywhere on your machine (recommended for skills you'll use across multiple projects) - `/.claude/skills//SKILL.md` — auto-loads only when working in that project (recommended for project-specific skills) Restart Claude Code or open a new session to register. **Using in Claude.ai, ChatGPT, Gemini, or other AI tools:** 1.
