One File Tools
Agents
Your script runs long and you are recording today. Open one HTML file in any browser - no install, no signup, no API key, no coding tool of any kind - and every line becomes a row you can keep, tighten or cut while the running total moves. It names the lines that would get you to your target, strips stock filler and reports what it cost, finds the block eating the overrun, checks a hook against the first seconds, and exports the recut script, caption cards and a printable shot list. Offline.
事業の情報を伝えるだけで、見積書と請求書を発行できる単一HTMLファイルをその場で作って渡します。屋号・住所・振込先・登録番号・通貨・税率・支払条件を焼き込んだ状態で出力。連番の自動採番、取引先と品目のプリセット、見積から請求へのワンクリック変換、税率ごとに区分した消費税額の表示、A4印刷でPDF化、JSON/CSVの書き出し。適格請求書の記載項目を入れる欄も用意します。買い切り版との違いは、税率が変わった時・項目を足したい時・年度が変わった時に何度でも作り直せることです。買い手の環境には何もインストールしません。税務・法務の助言ではありません。
事業の情報を一度伝えるだけで、見積書と請求書を発行できる単一HTMLファイルを作ります。自社情報・通貨・税率・支払条件を最初から入れた状態で出力。連番の自動採番、取引先と品目のプリセット、見積から請求へのワンクリック変換、印刷でPDF化、JSON/CSVの書き出し。適格請求書の記載項目（登録番号・税率ごとの区分と消費税額）を入れる欄も用意します。インストール・登録・APIキーは不要で、データは端末の中だけに残ります。税務・法務の助言ではありません。
Describe your business once and get a single HTML file that issues your quotes and invoices offline. Your details, currency, tax rates and payment terms are already in it. Auto numbering, client and item presets, quote to invoice in one click, print to PDF, JSON and CSV export. No install, no signup, no API key. Nothing is uploaded. Not tax advice.
A free single-file tool that tells you whether a short-form script fits your target length before you record it. Open the HTML in any browser - no install, no signup, no API key, no coding tool of any kind. Paste your script and get the estimated spoken length, a per-line breakdown marking your first cuts, a hook-length check, a warning for lines too long to read as captions, and a stopwatch that measures your own pace and recalibrates to it. Runs offline; your script is never uploaded.
重複判定のロジックと投稿履歴の保存先を貼るだけで、同じものを二度出す条件と、ガードが効きすぎて一度も出なくなる条件の両方を洗い出します。履歴の保持期間が切れて未投稿に戻る、ガードが毎回中止し続けてラインが恒久停止するデッドロック、失敗した投稿が履歴に残って永久にスキップされる、同時実行の競合など9項目を検査します。
1日あたりの投稿枠、補充の頻度と1回あたりの生産数、現在の在庫数を貼るだけで、週の収支とあと何日で枯れるか、週あたり何本足りないかを式の形で返します。休日だけの増枠が計算から漏れる、1回のバッチで作れる本数に上限がある、補充は成功しているのに量が足りない、作成済みと未使用を分けて数えていないなど9項目を検査し、安全在庫の決め方まで返します。
投稿の公開範囲設定と直近の再生数・表示回数の一覧を貼るだけで、「誰にも届いていない」原因を切り分けます。確認中の扱いで下書きに残る、公開範囲が非公開や限定公開のまま、同一タイトルの重複アップロード、興味分類と投稿ジャンルの不一致、タグの文字化けで検索の入口が消えるなど9項目を検査し、そのまま使える確認手順と次に投稿する時の作り方を返します。
ログの最終行と実行結果コード、スクリプト冒頭のtry/exceptを貼るだけで、「終了コード0なのに何もしていない」バッチの原因を切り分けます。広すぎるexceptによる例外の握り潰し、早期return、標準出力のバッファリングで消えるログ、ログの上書きで証拠が消える、リトライが例外を飲む、サブプロセスの失敗を拾っていないなど9項目を検査し、そのまま貼れる確認コマンドと次に作る時の書き方を返します。
Windowsタスクスケジューラの設定を貼るだけで、「登録されているのに動かない」「エラーも出ずに無言で止まる」原因を特定します。バッテリー駆動中の無言スキップ、日本語パスの文字化け、トリガーとアクションの1対1誤解、同時刻タスクの巻き添えなど9項目を検査し、そのまま貼れる確認コマンドと修正コマンドを返します。
化粧品・医薬部外品・健康食品・サプリの広告文を貼るだけで、薬機法第66条の虚偽誇大広告と医薬品的効能効果の標ぼうの観点から危ない表現を原文引用つきで指摘し、NG→OKの言い換え表と、訴求力を落とさずに書き直した安全版を返します。第66条の対象は「何人も」で、広告主だけでなく書き手本人も含まれます。
商品紹介やPR投稿の下書きを貼るだけで、ステマ規制と優良誤認・有利誤認の観点から危ない箇所を1行ずつ引用付きで指摘し、訴求力を落とさずに書き直した安全版を返します。媒体別のPR表記位置まで判定します。
Send a topic, get one complete faceless short-form video plan back in a single reply: three hooks with their visuals, a second-by-second shot list timed by speech rather than character count, TTS-ready narration, stock-footage search terms per shot, captions and tags for TikTok, Reels and YouTube Shorts, a cover-frame spec, and a retention review that names the seconds where viewers leave. Thirty requests is a month of daily uploads.
Paste a caption and get every hashtag checked for the silent corruption that kills tag-driven distribution. Check before posting, or compare what you intended against what the platform actually saved and see which tags died.
For one person publishing their own content on a schedule: describe your setup and get an operations kit that makes silent failures visible — a status board, a runbook with idempotent retry and queue-fallback patterns, an incident ledger, and a daily health-check specification.
Describe what your account has actually been posting — topics, languages, and the reach each group got — and get a diagnosis of whether reach collapsed because the account stopped being legible to the platform, plus a 30-day repositioning plan with the numbers that tell you if it is working.
Paste the one short video that outperformed your others plus its real watch-through, and get it turned into a repeatable series: a twelve-episode slate, the format spec extracted from what actually worked, a hook mechanism per episode, an escalation curve, and a retirement rule.
Paste the caption you intended plus what the platform actually saved, and get a character-level diff that catches silently corrupted hashtags, truncation, and stripped formatting — plus a paste-safe caption block built to survive the editor that mangled it.
Describe your cover frame candidates and get them judged at the size people actually see them: a self-contained HTML contact sheet at real grid and shelf dimensions, a legibility score for every text element, a ranked pick with the deciding reason, and redraw instructions for the runner-up.
Paste an item's cost and expected sale price to see net take-home across eBay, Poshmark, Mercari, Depop, Etsy, Amazon, Facebook Marketplace, Whatnot, Vinted & StockX side by side, plus a BUY/PASS/BORDERLINE sourcing call against your target margin. One-time purchase, no subscription, no API key.
Describe your profile and paste your links, get a single self-contained HTML file that works as your own link-in-bio page for a TikTok, Instagram, X, or YouTube bio. A buy-once alternative to hosted link-list services. Mobile-first: avatar, name, short bio, tappable link buttons, optional social icons, and a color theme. No install, no server, no account, no code. Open it in any browser and host it yourself.
Type a city or country, get a ready-to-post Japanese social pack: a 7-post Threads thread, an Instagram caption, and a YouTube Shorts script. For English-speaking creators running Japanese-audience travel/inbound accounts, or anyone outsourcing Japanese travel content. Note: all output is in Japanese (first-person "boku"), not English. Works for any city worldwide - Seoul, Taipei, Bangkok, Paris, New York, and more. No API key needed; add your own affiliate links.
Paste your staged changes, a diff, or a list of merged commits/PRs and get clean Conventional Commits messages, a grouped CHANGELOG entry in Keep a Changelog format, and a suggested Semantic Versioning bump (major/minor/patch) with the reason. Built for developers and coding agents (Claude Code, Codex) doing the everyday git loop and cutting releases. Uses only the pasted changes; unknowns are [FILL IN]. No API key, no repo access, no personal data.
Paste a git diff, get a review-ready pull request: a structured PR description (summary, what/why, test notes), risk callouts (migrations, API/contract changes, config, deletions), a reviewer attention map that surfaces the riskiest hunks first, and a self-review checklist tailored to the diff. For developers opening PRs with Claude Code, Codex, or any coding agent. Uses only the pasted diff; unknowns are [FILL IN]. No API key, no repo access, no personal data.
このSkillは、Claude Code / Codex / OpenClaw 向けのAIエージェント用Skillを多数設計・公開してきた実務知見を落とし込んだものです。よくある失敗（ホスト側でSkillが発火しない description、権限を広く取りすぎたサブエージェント、シークレットの直書き、プロンプトインジェクションへの無防備さ）を体系化し、再現可能な作成フローとして提供します。貼られた情報だけを使い、不明点は[FILL IN]として創作しません。出力に対して、シークレット漏えい・過剰権限・外部送信・インジェクション面のセルフ監査を行い、公開前に是正できるようにしています。個人情報は扱いません。
Built on the patterns that separate winning freelance proposals from ignored ones on Upwork, Fiverr, Freelancer, and OnlineJobs.ph. It applies a proven framework: open with the client's real problem, prove fit with one concrete result, and close with a clear next step — not generic "I'm hardworking and dedicated" lines. It encodes client-side hiring psychology, platform-tuned proposal length, and an honesty guardrail that never fabricates experience, leaving unverified claims as [ADD YOURS]
Generates TikTok Shop product descriptions plus multiple video opening hook lines for short-form video selling across Southeast Asia.
Generates ready-to-read Facebook Live selling scripts — opening hook, product walkthrough, urgency lines, and closing CTA — for live sellers and resellers.
Generates ready-to-paste WhatsApp Business catalog descriptions, auto-reply templates, and order-confirmation messages for small business owners and resellers.
I build small personal productivity tools and repeatedly needed a quick way to track data (books, inventory, expenses, habits) without a server or database. This skill packages that pattern: a reusable HTML/JS template (table, add/edit form, search/filter, chart, JSON/CSV export-import, localStorage) plus a workflow that adapts the template's fields to whatever the user describes in plain language. Output is a single offline HTML file, no account, API key, or server.
