xargs Ref geliştiren: Libor Benes (Dr. B)

🎯 xargs Ref brings a complete, structured reference for the xargs (extended arguments) utility
directly into your Firefox sidebar — always available alongside any tab you
are working in.

Every GNU/POSIX flag is presented with a description, a
ready-to-copy shell example, its specific limitations, and a highlighted
risk or failure mode. Designed for shell scripters, system administrators,
DevOps engineers, and security professionals who need fast recall without
leaving their browser.

🗂️ WHAT EACH ENTRY CONTAINS:
• Description — what the flag does, in plain English.
• 📋 Example — a minimal, copy-ready shell command.
• 🟨 Limitation — portability notes, edge cases, and behavioural quirks.
• ⚠️ Risk/Failure Mode — how the flag can go wrong in production.

🖥️ FEATURES:
🔎 Live search — filter instantly across all fields: flag name, description,
example, limitation, and risk. Result count updates in real time.

📋 Copy button — one click places the clean example command on the clipboard.

🟥 Risk boxes — every entry surfaces its critical failure mode in a
red-accented box so it is never overlooked.

🟨 Limitation boxes — constraints and portability notes appear in a distinct
amber-accented box, separate from the risk.

🟩 Security pattern cards — shell hardening entries are rendered with a green
left border and a SECURITY PATTERN badge, easy to spot when scanning.

🌗 Automatic dark mode — respects your system or Firefox colour scheme
preference.

🔒 SECURITY-FIRST ARCHITECTURE:
✅ No data collection — explicitly declared in manifest.json with
data_collection_permissions.
✅ No telemetry — no analytics, no external pings, no network requests.
✅ No eval() — safe, audited code.
✅ No innerHTML — all DOM built with safe features exclusively.
✅ Input validation — search input sanitised and length-capped before use;
no user input is ever inserted as markup.
✅ clipboardWrite only — the sole permission, used exclusively by Copy buttons.
✅ No icons — no binary assets in the package.
✅ Flat file structure — four files at the root, no nested directories.
