Editorial Policy
The publishing and verification rules we follow to keep our guidance useful and checkable.
Last reviewed: October 17, 2026
4-Step Mathematical Verification & QA Pipeline
These are the checks used when updating content, not a claim that every tool and input has been verified. Separate source review, numerical checks and browser behavior, and state the conditions and limits of each check.
Standards & Primary Sourcing
Choose primary references directly supporting the formula and units. Check edition and scope; a public overview is not a full standards compliance review.
Independent calculation checks
Publish the inputs, units and assumptions of worked examples. Compare with an independent calculation where stated. Assumed values are not measurements.
Playwright E2E Tests
Check relevant input, result, error and saving flows. Distinguish code checks, automated browser tests, viewport emulation and physical devices. Test counts cannot guarantee every input.
Re-verification & Changelog
Use real update dates and describe what changed. Check reported errors against sources and calculation conditions; do not label unchecked claims as verified.
Reproducible explanations and their limits
Worked examples state inputs, units and assumptions so readers can reproduce them. Figures distinguish calculated models from measurements and sourced data. Checking a public standards catalog is not the same as reviewing its full text. We do not claim unverified expert review, experiments or standards compliance.
Editorial purpose
Tools Hub creates tool instructions and guides to help people finish a real task safely and quickly. We do not add content solely to target rankings, keywords or arbitrary word counts.
How we verify
Core tool flows are checked through real browser use and automated tests. Instructions are compared with the published tool, and primary sources are preferred for specifications and numerical claims. Unverified outcomes and rankings are not presented as facts.
Sources and updates
We prioritize standards, official documentation and first-party references, and link to them where readers can verify a claim. Updated dates change only after a meaningful change to the content, specification or verification.
Use of AI assistance
AI may assist with writing, translation, proofreading and implementation. Before publication, we check primary sources, links, conversion examples through automated tests, and behavior in the browser. We do not claim that every article has been reviewed by a human subject-matter expert. Unverified AI-generated figures, quotations or experiences are not published.
Privacy
We do not collect files, text, passwords or calculation values entered into tools for editorial or analytics purposes. The browser-only processing model remains a product requirement.
Corrections and contact
When an error or outdated statement is reported, we verify and correct it, noting a meaningful update when appropriate. Please use the contact page to report an issue.
