How matches are found. Word for word: the exact same text. Edited: shares passages with this file (“99% same” means 99% of its five-word phrases also appear here; 10% or more counts). Their own version: similar meaning, or, weakest, the same name. We can’t tell which project had it first. Projects are counted among the 200 most-starred candidates, and mentions are links to the repository we found, up to 50 per site, so both counts are a floor.

Alt-Text-Generator
Erzeugt sachliche, kontextpassende Alt-Texte und erkennt dekorative Bilder, die alt="" bekommen.
Wann verwenden
- Bilder brauchen
alt-Texte oder vorhandene sollen geprüft werden. - Entscheidung nötig, ob ein Bild informativ oder dekorativ ist.
Input
- Bild (oder Beschreibung) plus Kontext: Wo steht es? Welche Funktion? Ist es ein Link/Button?
Prüf-Vorgehen
- Funktion klären: informativ, dekorativ, funktional (Link/Button) oder Text-im-Bild?
- Dekorativ (rein schmückend, Info steht im Text daneben) →
alt="". - Informativ → beschreibe, was im Kontext relevant ist, knapp und sachlich.
- Funktional (Bild in Link/Button) → beschreibe das Ziel/die Aktion, nicht das Bild.
- Text-im-Bild → den Text 1:1 in
alt. - Logo → Firmenname (in Link zur Startseite: Firmenname genügt).
Output
Je Bild:
- Ort: Datei/Selektor.
- Empfehlung:
alt="…"(oderalt=""bei dekorativ). - Begründung: knapp, warum dieser Text.
- Priorität: hoch (funktional/informativ ohne alt) / niedrig (Feinschliff).
Gotchas
- Kein „Bild von …" / „Grafik zeigt …" — Screenreader sagen die Rolle bereits an.
- Kontext entscheidet: dasselbe Bild braucht in Artikel und Teaser oft unterschiedliches
alt. - Fehlendes
alt(Attribut ganz weg) ≠alt=""— ohne Attribut liest der Screenreader oft den Dateinamen vor. - Bei funktionalen Bildern beschreibt
altdas Ziel, nicht das Motiv. - Redundanz vermeiden: steht die Info schon als Fließtext daneben, ist das Bild oft dekorativ.

Your trail
Files you open will collect here, so you can find them again.
Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.
Now do this for your own.
Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
