Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

Prismalux AGENTS.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 17d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

AGENTS.md — Regole fisse per agenti (Prismalux)

Queste regole valgono per ogni agente che lavora su questo repository.

1. Report all'utente: sempre in tabella

Quando l'utente chiede un report, un riepilogo, uno stato dei lavori, un elenco di cosa manca o l'esito di test/modifiche, la risposta deve essere una tabella Markdown.

  • Una riga per voce, con colonne chiare (es. Cosa, Stato, Dettaglio, Prossimo passo).
  • Usare ✅ fatto, 🟡 parziale/da verificare, ⬜ da fare, ❌ bloccato.
  • Dopo la tabella sono ammesse solo poche righe di note o eccezioni.
  • Non sostituire la tabella con elenchi puntati o prosa come formato principale.
  • Le risposte conversazionali brevi (una domanda secca, un chiarimento) possono restare testo.

2. Fonti di verità

  • TODO.md — cose da fare e stato.
  • MAP_CODE_AGENT.md — mappa del codice, flussi e trappole.
  • gui/CLAUDE.md — convenzioni di sviluppo della GUI.
  • TODO.md e MAP_CODE_AGENT.md vanno aggiornati quando si completa un task.
Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
