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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00218 | $0.00218 |
| Opus 5 | $0.00109 | $0.00109 |
| Sonnet 5 | $0.00044 | $0.00044 |
| Haiku 4.5 | $0.00022 | $0.00022 |
Grade A, and why
devoxx-2026 copilot-instructions.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 5d 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
Copilot Instructions — Projet Anomaly Reporter
Ce fichier configure GitHub Copilot pour ce projet. Pour les instructions partagées cross-agents, voir AGENTS.md à la racine.
Architecture
Ce projet suit une Clean Architecture (Flutter) et une Architecture Hexagonale (Rust). Les règles de dépendance et conventions sont définies dans AGENTS.md.
Conventions clés (résumé de AGENTS.md)
- Frontend Flutter : flutter_bloc, get_it + injectable, Either<Failure, T> via dartz
- Backend Rust : axum + serde_json (REST/JSON), sea-orm, Result<T, DomainError>
- Tests BDD avec fichiers .feature Gherkin
- Dépendances vers l'intérieur uniquement (domain ne dépend de rien)
- TDD : écrire le test avant l'implémentation
Workflow
- Lire le .feature BDD concerné
- Implémenter domain/ d'abord
- Vérifier : flutter test + dart analyze + cargo test + cargo clippy
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.

devoxx-2026 copilot-instructions.md is an instructions file published in the GitHub repository b-fontaine/devoxx-2026 (5 stars, last pushed 4mo ago), licensed MIT. It adds 218 tokens to every session, about $0.0011 per session on Opus 5. A static security scan graded it A with 0 findings.
