• GET/skills/fixed-width-to-csv/file$0.03Fixed-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…
• GET/skills/chain-evidence-check/file$0.05Chain Evidence Check — Judges whether an on-chain observation really proves a claim about a payment, a wallet or an RPC endpoint on an EVM chain, and answers as JSON with a binary verdict, the reason and the one check that would decide. Knows the readings that answer for the wrong thing - a null transaction receipt seconds after settlement, a block explorer that indexes a minute late and a balance view that lags its own transfer list, a public RPC endpoint that refuses receipts with an error or…
• GET/skills/skill-md-review/file$0.05SKILL.md Review: Safe and Within the Limits — Reviews a SKILL.md file before you install, buy or publish it and lists every problem with a fixed code, the place and a fix, then gives one verdict. It checks the front matter against the published limits (name up to 64 characters in lowercase, hyphens and digits, no reserved words; description present, up to 1,024 characters, naming both its job and the requests that should trigger it, in the third person), and it reads the body for hidden orders …
• GET/skills/canonical-url-decision/file$0.05Canonical URL Decision — Decides for every URL variant of a page whether it is the canonical URL, gets a canonical tag to another address, a permanent redirect, a noindex, a 404 or 410, or cannot be settled from the facts given, answered as JSON only with the target and a short reason per URL. Follows Google's current canonicalization guidance on duplicate content - a redirect when the duplicate is deprecated, rel=canonical when it must stay reachable (tracking parameters, print views, a produc…
• GET/skills/cron-schedule/file$0.06Cron Schedule for Cloudflare Workers — Turns a schedule described in words into cron expressions for Cloudflare Workers Cron Triggers, answered as JSON with the crons and a note. Knows where Cloudflare differs from classic cron, measured on a live Worker - day-of-week 1 is Sunday, so 1-5 runs Sunday to Thursday and 7 is Saturday, while 0 and ? are rejected; times are UTC only. Writes day names instead of numbers, uses L, LW, W and # for last and n-th days, splits intervals that do not divide an…
• GET/skills/log-lines-to-jsonl/file$0.01Log 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…
• GET/skills/nextjs-cache-review/file$0.03Next.js Cache Review: ISR, Tags, Redirects — Reviews pasted Next.js App Router code and config that runs on Cloudflare through OpenNext, for caching and ISR mistakes that serve a wrong or stale answer, or make every visit read the database. It flags an unstable_cache key whose cached shape changed while the key stayed, force-dynamic pages that disable the browser back-forward cache, a wildcard Cache-Control override that makes the whole site dynamic, a dynamic route that never starts ISR becaus…
• GET/skills/spreadsheet-formula/file$0.01Spreadsheet 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…
• GET/skills/llm-api-fallback-review/file$0.05LLM API Fallback Review: Gemini, Groq, Chains — Reviews pasted code that calls a language model (JavaScript, TypeScript or Python; REST, @google/genai, google-genai, or an OpenAI-compatible client for Groq), usually through a chain of models or providers with retries. It finds where the call path goes silent or stops while another model would answer (an empty 200 taken as the answer, a 429 or 5xx that ends the call, a retired model's 404, a Groq schema 400 that drops the provider, one provider'…
• GET/skills/watchdog-alert-review/file$0.02Watchdog Alert Review: Silent and Noisy Alarms — Reviews pasted code or a design for a liveness watchdog, a staleness alarm or a daily heartbeat mail (sources that must keep answering, a pipeline that must keep publishing) and lists every way it stays silent on a dead source or floods on a healthy one. It checks whether silence is measured in the time the source was last asked or by the wall clock, whether a stateless alarm window repeats or never fires, whether the threshold is longer than the…
• GET/skills/android-strings-translate/file$0.01Android Strings Translate: strings.xml That Still Builds — Translates an Android string resource file (res/values/strings.xml) into another language and returns the whole XML file, so the Android build and the app accept it. Only the text between the tags changes. Resource names, attributes, comments, placeholders such as %1$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…
• GET/skills/traffic-reality-check/file$0.07Traffic Reality Check: Real Readers vs Bots — Reads the numbers from Cloudflare Web Analytics and zone analytics (GraphQL or the dashboard) and says how many of them are real readers or real server errors, answered as JSON with the computed figures and a short reason. Knows what pollutes the table - the owner's own headless-browser checks, link-preview fetches from the social network that show up as referrals, the site's own Worker and its cache calls counted as visitors or as 5xx errors, the r…
• GET/skills/spend-guard-review/file$0.03Spend Cap Review: Do Cost Limits Really Stop? — Reviews pasted code and configuration that spends money (paid AI or API calls, purchases, paid lookups, anything billed per use) and checks whether the limit on that spending really stands in the way of the spending. It flags a cap that sits beside the path instead of on it (a gateway limit while a script calls the provider directly, a counter only in the browser), a missing setting that means no limit, an alert or a budget email used as the prote…
• GET/skills/tests-from-spec/file$0.03Tests from Spec: Cases from the Requirements — Writes test cases for a function from its specification rather than from its code, as a JSON table that any test runner can loop over. Every rule, boundary and error the spec defines gets a case, and every expected value is worked out from the spec; where the code you show disagrees with the spec, the case follows the spec and a note says where. Behaviour the spec leaves open becomes a question instead of a guessed case. Use to write unit tests fro…
• POST/run/payment-header-check$0.005Payment Header Check API: reads an x402 PAYMENT-SIGNATURE header before you send it - base64/UTF-8/JSON, version, authorization fields, clock window, who signed (lane a or b) and, with the seller PAYMENT-REQUIRED, payTo/amount/network/asset. Nothing is sent anywhere. $0.005 USDC per check. POST JSON {payment_signature, payment_required?}; free example at https://api.aiskills402.com/v1/run/payment-header-check/example
• GET/skills/reply-language-lock/file$0.07Reply Language Lock: Answers in the User's Language — Keeps an assistant answering in the language the user writes in, whatever the language of the pasted text, the logs, the code comments, the tool output or the documents it works from. Covers the slips that happen in practice - drifting into the language of an English log or a Russian forum post, mixing in words or letters of a close neighbour (Russian in Bulgarian or Ukrainian, Czech in Polish, Portuguese in Spanish, Dutch in German), answer…
• GET/skills/redirect-map/file$0.01Redirect Map Builder — Turns an old-URL list and the mappings you have into a redirect map as JSON - one rule per old URL, chains collapsed to the final target, loops reported and never emitted, queries and percent-encoding kept as written, and old URLs with no named target listed as unmapped instead of guessed. Also writes the same map as a Cloudflare Pages style _redirects file. Knows the status codes (301 for a moved page, 308 where the method must be kept and what Next.js really sends for p…
• GET/skills/json-diff-paths/file$0.01JSON Diff Paths — Compares two pasted JSON documents, BEFORE and AFTER, and lists every value that differs as strict JSON, one entry per changed path, with the old and the new value. Paths are JSON Pointers, types are strict (the string "1" is not the number 1, null is not a missing key, an empty array is not an empty object), arrays are compared by index with no move detection, object key order and number spelling (1.0, 1e2) are not changes, and a document that is not valid JSON is refused, ne…
• GET/skills/html-table-to-csv/file$0.02HTML Table to CSV: Merged Cells and Entities Done Right — Converts one HTML table into RFC 4180 CSV and answers with the CSV only, no code fence. The header is the first row, every cell keeps the text a browser shows after entities are decoded (&, €, —, a no-break space), links, bold and other inline markup vanish and their text stays, a line-break tag becomes a space, and numbers such as 1,250 stay text in quotes. A cell that spans rows or columns (rowspan, colspan) repeats its …
• GET/skills/llms-txt/file$0.02llms.txt Writer — Writes an llms.txt file in the shape the llms.txt proposal defines, from a site description and a list of pages, answered as the Markdown file only. One H1 with the site name, a blockquote summary, optional plain notes, then H2 sections that hold lists of links in the form "- [name](address): notes". Every address is absolute (a relative one is joined to the stated origin) and copied exactly, never invented; pages marked noindex, private or behind a login are left out; a page …
• GET/skills/test-guard-review/file$0.03Test Review: Can This Test Ever Fail? — Reviews a pasted test, check script, smoke test, mutation script or CI step and says whether it can fail when the thing it guards is broken, so a green result is worth something. It finds a completeness guard that counts its own hard-coded list instead of the directory, a one-star glob that never enters subfolders, a mutation script that restores with git checkout and wipes the uncommitted fix under test, a null test that an empty string passes, a status …
• GET/skills/accessibility-review/file$0.03Accessibility Review: WCAG Defects in Markup — Reviews pasted HTML or JSX for the accessibility defects a screen reader or keyboard user hits first, and names the WCAG 2.2 success criterion for each. It flags images without a text alternative, form fields without a label, buttons and links with no accessible name, clickable elements that a keyboard cannot reach, focusable content hidden from assistive technology, personal-data fields without autocomplete, data tables without header cells and pa…
• GET/skills/po-translate/file$0.02Translate .po Files Without Breaking Gettext — Translates the messages of a gettext PO file (.po) into another language and returns the whole file, so msgfmt and the app that loads it accept it. Only the msgstr values change. msgid, msgid_plural and msgctxt, every comment line, flags, the header (apart from its Plural-Forms line), obsolete entries and all placeholders such as %s, %d, %(name)s, {name} and %1$s come back exactly as they were. Entries with plural forms get exactly the number of ms…
• GET/skills/srt-translate/file$0.02Subtitle Translator for SRT and VTT — Translates a subtitle file (SRT or WebVTT) into another language and returns the whole file with only the spoken words changed. Cue numbers, timing lines, cue settings, position codes, speaker names, style and note blocks come back byte for byte; every cue stays one cue, in the same order, with at most two lines of at most 42 characters, shortened in wording when the translation is longer. Tags and markers such as italics, colours, music notes, dialogue das…
• GET/skills/bing-indexnow-submitter/file$0.04Bing and IndexNow Submitter Review — Reviews code and answers questions about sending page addresses to search engines through IndexNow and the Bing Webmaster URL submission API, and catches the mistakes that make a submitter report success that never happened. It flags a Bing call judged only by its HTTP status when the refusal sits inside the body, a retired XML or SOAP endpoint, a fallback chain that retries after a refusal that is ours, a quota read as one number instead of two, an unread q…
