Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.01022 | $0.01022 |
| Opus 5 | $0.00511 | $0.00511 |
| Sonnet 5 | $0.00204 | $0.00204 |
| Haiku 4.5 | $0.00102 | $0.00102 |
Grade A, and why
09-github-identity-marco-porcellato 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 9d 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.
How it starts
The opening of the file, as written. The whole thing — 80 lines — stays where its author put it; the contents beside it link to each section on GitHub.
GitHub — Marco Porcellato only (divieto assoluto Cursor/AI)
TASSATIVO E ASSOLUTO: nulla di ciò che finisce su GitHub (remoto pubblico o privato del repo) può contenere riferimenti a Cursor, Composer, agenti AI, o attribuzione che il lavoro sia stato fatto da un assistente. Operare solo come Marco Porcellato, maintainer.
Rule routing: Complements 08-github-workflow-standards.mdc, the user rule for gh pr create, and 05-release-preparation.mdc.
Cosa copre “finisce su GitHub”
Qualsiasi artefatto sincronizzato con il remoto o visibile nell’UI GitHub:
| Artefatto | Esempi |
|---|---|
| Commit | messaggio, subject, body, trailers (Co-authored-by, Signed-off-by, Reviewed-by) |
| Branch | nome branch pushato |
| PR | titolo, body, review, commenti inline, merge/squash commit message |
| Issue | titolo, body, commenti, milestone description |
| Release | tag message, release notes, draft |
| Actions / CI | commenti bot maintainer, workflow commit messages se pushati |
| Wiki / Discussions | post come maintainer |
Comportamento obbligatorio
- Voce maintainer — come se Marco avesse scritto direttamente (conciso, tecnico).
ghe git che toccano il remoto solo su richiesta esplicita dell’utente (push, merge, release).- Prima di ogni
git pushogh pr merge/gh pr create: verificare che messaggi e metadati siano puliti (vedi checklist sotto).
Divieto assoluto — zero footprint Cursor / AI
Non aggiungere mai segni che l’azione sia stata fatta da Cursor, Composer, un agente, o “AI-assisted”:
| Superficie | VIETATO |
|---|---|
| PR / issue | “Generated by Cursor”, “AI-assisted”, link cursor.com, ID agent/transcript |
| Commit | Co-authored-by: Cursor, Co-authored-by: Composer, Signed-off-by: AI, cursoragent@ |
| Trailer git | --trailer o HEREDOC con Cursor, OpenAI, Anthropic, “Agent”, “Composer” |
| Commenti | “As an AI…”, “I'm Cursor…”, “Bugbot/Agent suggested…” |
| Release | branding tool; note = stile CHANGELOG.md maintainer |
| Branch | prefissi cursor/, agent/, composer/ salvo richiesta esplicita di Marco |
| UI GitHub | campi “assistant attribution” → lasciare vuoti |
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.

09-github-identity-marco-porcellato is a cursor rule published in the GitHub repository MarcoPorcellato/matryca-plumber (97 stars, last pushed yesterday), licensed Apache-2.0.
