# Threadwave Preflight > Run the mandatory readiness gate for every ThreadWave Twitter/X workflow: require the update skill, confirm every release-index roster skill's individual version through GitHub, offer supported-version continuation, run approved skill and CLI updates as separate component-scoped flows through the canonical setup guide, verify the tw CLI and supported contracts, check the Chrome extension/setup relay, preserve the original request, and route sanitized failures to threadwave-error-support. Use before twitter-automation, twitter-agent, twitter-post, or twitter-reply, and for ThreadWave setup, update, readiness, dependency, or repair requests. 中文：用于所有 ThreadWave 推特工作流的强制预检，检查发布索引中的技能版本、允许继续使用受支持版本、通过官方设置指南按组件分别更新 skill 和 CLI、检查 Chrome 扩展与依赖，并将净化后的故障转交给 threadwave-error-support。 - Skill: `ohmyskyhigh/threadwave-preflight` (Agent Skill, multi-file: 5 files) - Install (CLI): `npx skillmds@latest add ohmyskyhigh/threadwave-preflight` - Raw SKILL.md: https://api.skillmd.com/api/skills/ohmyskyhigh/threadwave-preflight/raw - Safety review: pending - Works with: Claude Code, Claude.ai, OpenAI Codex - Category: Web & Frontend - License: MIT-0 - Author: ohmyskyhigh (https://skillmd.com/u/ohmyskyhigh) - Updated: 2026-09-17 - Page: https://skillmd.com/skills/ohmyskyhigh/threadwave-preflight --- # ThreadWave Preflight Own the single mandatory preflight, setup, and recovery contract. Every operation skill in the release-index roster calls this peer by name before any `tw` command. `threadwave-error-support` owns post-failure classification, solution search, and report generation. `greeting-balance` mode is the sole lightweight exception. It runs only the contract's fixed `tw credits --format json` lookup for the starter menu, skips update and readiness checks, and returns the balance or unavailable without repair. ## Mandatory Flow Read [references/preflight-contract.md](references/preflight-contract.md) completely. Unless the caller selected `greeting-balance` or issue-report-only mode, at the start of each new ThreadWave task, run its skill update check and regular CLI preflight. A receipt-aware CLI reuses its durable readiness/capability receipt while rolling inactivity is under 12 hours and performs the full check when stale or invalidated. A supported CLI result that omits `data.readiness_reuse` selects legacy full-check mode: regular preflight is already a full check, so never invoke `--force` in that mode. A review decision alone is not a new task boundary. Select and retain the contract's platform invocation adapter before the first CLI readiness call. A Windows packaged install uses the absolute system `cmd.exe` and canonical managed `tw.cmd` only for the fixed readiness templates; it never invokes a version-directory `tw.exe` or inserts user content into `cmd.exe /c`. After packaged Windows readiness, downstream commands with dynamic values use the contract's true per-argument process form. On PowerShell/.NET hosts this means `ProcessStartInfo.ArgumentList`; direct `& tw.cmd @args`, `Start-Process -ArgumentList`, and manually composed `Arguments` or `/c` strings are forbidden because they can split or reinterpret one logical value. On a native Windows Codex host, run those fixed readiness templates through an already-available non-sandboxed local process capability from the first call. Do not probe inside the sandbox or ask the user to approve or choose this execution boundary. This is not administrator or UAC elevation, and it never widens the closed command mapping. The one-way dependency is: ```text twitter operation skill -> threadwave-preflight -> threadwave-update failed workflow -> threadwave-preflight -> threadwave-error-support ``` Never call an operation skill during preflight. Return readiness to the originating skill after checks pass. Never call `threadwave-update` again when routing issue-report-only mode. ## Setup Ownership When a required skill, CLI, or Chrome extension module is missing or incompatible, preserve the original request and use: `https://www.threadwave.xyz/cli/setup/agent.md` A supported older skill or CLI is non-blocking. Offer one localized choice only when the user has not already decided in this agent session for the exact same offered versions: continue with the installed versions, or update now. Continue only after the originating capability gate passes. Scope the guide to the affected component. A missing, incompatible, or approved skill update uses `skills_only` and never runs a CLI installer, `tw update`, `tw setup`, daemon repair, or native-host registration. A CLI-only update uses `cli_only` and never fetches or installs skills. When both are pending, use `skills_and_cli` and complete the CLI path before the skill path. Reserve `full_setup` for initial setup or missing/unknown core runtime readiness. When the user approves the update, fetch the fixed guide through process execution, follow only the selected current-host scope yourself, run one post-update preflight selected by the contract, and resume the preserved request. Use regular preflight for legacy mode or a changed CLI version, install mode, adapter, or launcher; use forced preflight only for the same confirmed receipt-aware CLI. Do not send the user to a browser, ask them to paste the guide, or ask them to type terminal commands. Pause only for the guide's user-owned Chrome, sign-in, payment, or X gates. Setup or update success is not approval for strategy, content, posting, replying, or another X mutation. ## Language Support English and Simplified Chinese requests. Choose explicit user preference first, then the latest message, then conversation language, defaulting to English. Keep skill names, commands, JSON keys, refs, schemas, and stable error codes in English. Never translate or normalize exact post/reply content. ## Error Support Handoff Direct error, solution-search, and report requests activate `threadwave-error-support` without preflight. For a potentially report-worthy workflow failure, stop the workflow and pass only the sanitized handoff fields defined by the preflight contract. Issue-report-only mode remains only as a compatibility route: it accepts already-sanitized diagnostic metadata, skips the update/preflight loop, and hands the payload to one separate `threadwave-error-support` task. If task creation is unavailable, return one pasteable handoff. Do not classify, search, render the report, retry, or resume the failed workflow here. ## Return Format ```text State: Completed: Versions: Preflight: Problem: Waiting for you: Next: Error support: ```
