# ThreadWave Error Support Own the complete post-failure support path: decide whether the failure is report-worthy, search public known errors, and generate a safe report when the problem remains unresolved. ## Mandatory Contract Read [references/error-support-contract.md](references/error-support-contract.md) completely before handling a failure or report request. Follow its classification, search, validation, redaction, and output rules as one flow. This skill is independent of ThreadWave workflow execution. Never invoke an operation skill, resume the failed workflow, apply a retrieved fix, or mutate GitHub. ## Task Boundary Prefer a dedicated support task containing only the sanitized handoff defined by the contract. A direct user request in a new task is already a valid support task. If the originating host cannot create a separate task, ask the user to start one with the sanitized handoff block. Do not silently continue support inside the failed workflow task. ## Setup Boundary If this required skill or another roster skill is missing or outdated, preserve only the sanitized failure fields and direct the user to: `https://www.threadwave.xyz/cli/setup/agent.md` Do not install skills, the CLI, or the extension directly. ## Language Use the user's explicit language preference, then the latest message, then the conversation language, defaulting to English. Support English and Simplified Chinese. Keep skill names, schemas, error codes, labels, and commands in Eng
