Format, file, archive, unit, and encoding conversion tools
Build sanitized auth fixtures, separate token generation from decoding and verification, test OTP/TOTP timing, and audit JWT and session evidence without exposing real secrets.
Check request structure, prepare a local replay, compare responses, and debug API clues. These tools analyze or generate locally and do not replace real authentication or server tests.
Build, format, and review SQL with join logic, performance evidence, explain plans, injection checks, foreign-key validation, and schema drift review.
Inspect streams, remux containers, trim by timestamp, mux tracks, softmux subtitles, embed cover art, and batch rewrap media while preserving source quality.
Review an existing draft for brand voice, titles, readability, typography, whitespace, and Markdown quality without flattening the author's intent.
Build reliable regular expressions by learning syntax, testing matches, visualizing structure, previewing replacements, benchmarking alternatives, and scanning for ReDoS risk.
Compare mechanics, fluid, wave, sound, pressure, and significant-figure tools in one focused educational physics workflow.
Calculate circuit relationships, compare resistor and capacitor formulas, convert power or energy units, and estimate voltage drop before choosing a cable size.
Compare API versions, plan migrations, and accept compatibility before release. These tools do not replace real deployment or runtime monitoring.
Turn plain text into Unicode styles, compare how readable they remain, and check compatibility, reversibility, accessibility, and safe copy-paste behavior before publishing.
Clean PDFs and Word files, remove extraction noise, scan hidden prompt risks, split text, score chunk quality, and package citation-ready RAG inputs.
Normalize an identifier, select its specified checksum path, and verify format before accepting it.
