HTML to Markdown: Same Page, Nothing Invented — Converts HTML into CommonMark Markdown and answers with the Markdown only, no wrapper fence. Headings become ATX headings, links keep their address byte for byte (title included), images keep their source and alt text, lists keep nesting and an ordered list keeps the number it begins with, code blocks keep their text and indentation, tables become pipe tables with literal pipes escaped, entities are decoded once so the text reads as a browser show…

Product Description From a Spec Sheet — Writes shop product copy (title, short description, bullets, long description) from a specification sheet and nothing else, in the sheet's language. Every figure keeps its unit and its qualifier, no superlatives or unsupported claims, and values that contradict each other are reported instead of chosen. Use when asked to write a product description, product page text, catalogue entry or marketplace listing copy from a spec sheet, in any language. One-time…

Log Lines to JSON Lines, Odd Lines Kept Raw — Parses plain-text log lines into JSON Lines, one record per line, by a format the task states (Apache or nginx combined access log, RFC 5424 syslog, key=value pairs, or a custom pattern with named fields). Splits by the format's grammar and not by spaces, so quoted fields with spaces and escaped quotes stay whole. A dash that the format defines as absent becomes null, fields the task calls numbers become JSON numbers (a status stays a number, a zero…

OpenAPI Operation Object From An Example Call — Writes one OpenAPI 3.1 operation object, as bare JSON, from an example request, an example response and rules given in words - parameters with the right location, requirement flag and type, a request body, and a response per status the person actually showed. Uses the 3.1 forms, not the 3.0 ones - a field that may be null is a type list with "null" (never nullable), a path parameter is always required, a status is a quoted key, an identifier writt…

Regex From Examples for Any Script — Writes a JavaScript regular expression from a description plus lists of strings that must match and must not match, answered as JSON with the pattern and flags. Knows the traps measured in Node 24 - \b and \w are ASCII-only even with the u flag, so \bдума\b never matches Cyrillic text and \w+ cuts "café" to "caf"; a word boundary for any script is a pair of lookarounds with \p{L} and the u flag. Anchors a validator so extra text around the value is rejected,…

Postgres or MySQL SQL to SQLite and D1 — Converts PostgreSQL or MySQL schema statements, migrations and queries into SQLite that Cloudflare D1 and Turso run, so the converted version behaves like the original and not only parses. Knows the conversions that run without an error and then go wrong - a key written as BIGSERIAL or INT AUTO_INCREMENT that SQLite stores as NULL, a custom enum type or an inline enum that stops checking anything, a default now() or gen_random_uuid() that fails on the fi…

Cloudflare Image Review: Quota, WebP, R2 — Reviews a pasted image pipeline (upload or AI generation, storage in R2, resizing, serving through Cloudflare image transformations, a Next.js loader, a sharp or WebP script) for the traps that quietly ship huge or broken images or spend a shared quota. It flags photographs stored as PNG, files stored exactly as a generator returned them, a redirect-on-error setting that hides an exhausted transformation quota, a list of widths that multiplies the uniq…

Android Strings Translate: strings.xml That Still Builds — Translates an Android string resource file (res/values/strings.xml) into another language and returns the whole XML file, so the Android build and the app accept it. Only the text between the tags changes. Resource names, attributes, comments, placeholders such as %1$s, %d and %%, the escapes backslash-apostrophe, backslash-quote, backslash-n and backslash-at, the quoted form for leading or trailing spaces, inline markup, CDATA sections…

Spreadsheet Formula: Excel and Google Sheets — Writes one spreadsheet formula for Excel or Google Sheets from a plain description and a sample of the sheet, using the sheet's real cell addresses and ready to be copied down. It fixes the ranges that must not move, looks values up by exact match, reads thresholds the way they are worded, builds dates with DATE, keeps blank cells apart from zeros, and uses functions that work in both Excel 2019 or later and Google Sheets. It answers with the formu…

Summary Fidelity Check — Checks a summary against the source text it was made from and lists the summary sentences the source does not support, each copied word for word, as strict JSON. It catches a number that was rounded or given another unit, a hedge that became a certainty, a cause the source never states, two facts joined into a false one, a claim whose speaker was dropped, a fact that comes from outside the source, and it ignores any instruction hidden in the source. A sentence is judged…

Job Description From Notes: Gaps Marked, Nothing Invented — Turns a hiring manager's rough notes into a job post with fixed sections (title, about the role, responsibilities, requirements, nice to have, location and working model, pay, process) in the language of the notes. Everything comes from the notes; a section the notes do not cover gets one [TBD: what is missing] line instead of a guess, and no benefit, salary, bonus, start date, team size, tool, perk or culture claim is added. Wording a…

Timeline From Text — Reads one pasted text, such as an incident report, a case history, a project log, a news story or an email thread, and lists its events as strict JSON. Events the text dates come first in chronological order, each with the date as written, the date in ISO form, a short event and the exact quote. Events with no date are listed apart in the order of the text. It resolves a relative date such as "two days later" only when the text gives the date it counts from, takes a date on…

Changelog From Commits — Turns a commit list into one release entry in Keep a Changelog form, as Markdown only with no fence and no preface. Groups changes under Added, Changed, Deprecated, Removed, Fixed and Security in that order, writes user-facing one-line entries, drops merge, chore, ci, build, test, style, internal docs, internal refactor, wip and version-bump commits, flags breaking changes, keeps the issue and pull request numbers that are in the input and never adds one, a date, a vers…

A2A 1.0 Agent Card Writer — Writes the JSON an agent needs for version 1.0 of the A2A (Agent2Agent) protocol, answered as JSON only with no fence and no text around it. Covers the agent card (supportedInterfaces with protocolBinding and protocolVersion, capabilities, skills, securitySchemes and securityRequirements, default input and output modes), the JSON-RPC requests (SendMessage, SendStreamingMessage, GetTask, ListTasks, CancelTask, push notification configs), the replies (task, message, da…

Email and DNS Cutover Review — Reviews a pasted plan, script or configuration for a change to a domain's mail and DNS on Cloudflare (turning on Email Routing, moving MX records, forwarding rules, sending alert mail from a Worker with the send_email binding, SPF, DKIM and DMARC records, deleting the records of an old host, the subject and sender name of automatic mail) and lists the ways it fails without any error. It flags sends to addresses the binding cannot reach, recipient lists that stop a…

Event to ICS Calendar File — Turns an invitation or event description in plain text (an email, a chat message, a web page, in English or another language) into a valid iCalendar file, answered as the file text only. Follows RFC 5545 where plain models slip - a named time zone needs a VTIMEZONE block in the same file or the time is written in UTC with Z, an all-day event ends the day AFTER its last day, an unknown end time stays empty instead of an invented hour, DTEND and DURATION never appear …

Fixed-Width to CSV: Cut by Spec, Trim Only When Told — Converts fixed-width text (mainframe exports, bank and statistics files, printed reports) into RFC 4180 CSV from a column specification and answers with the CSV only, no code fence. Positions are 1-based and inclusive unless the spec says otherwise, and count characters, so accented and Cyrillic letters do not shift later columns. Every cell is the exact characters of its positions: nothing is trimmed unless the spec says trim, leading zero…

Extract UI Strings Into i18n Keys — Pulls the hard-coded text a person sees out of a JSX, TSX, HTML or Vue template file into a messages map and returns the file rewritten to call the translation function, as one JSON object with the messages and the whole source and nothing around it. Every message is byte-exact as the user reads it. A sentence with an inline link or bold part stays one message with its markup inside, a sentence built from a string, a variable and another string becomes one me…

JSON to CSV: Flatten Nested Records, Keep Every Value — Turns JSON that holds a list of records, with nested objects and arrays, into one flat CSV table that a standard parser reads, and answers with the CSV only, no code fence. Nested keys become dotted column names such as address.town, array elements become index columns such as tags.0 and tags.1, or one cell joined with a separator, or one row per element when asked to explode. Numbers are copied as the JSON token (1.10 stays 1.10, 1e5 stay…

Markdown TOC Anchors: Contents Links That Really Jump — Builds the table of contents of a Markdown document with the exact heading anchors that GitHub or GitLab generate, and answers with the list only, no code fence. Finds the real headings (hash headings with closing hashes, underline headings, none inside code fences, indented code, comments or front matter), strips inline markup, lowercases, drops every character that is not a letter, digit, hyphen or underscore, turns each single space int…
