What is devoxx-2026 GEMINI.md?

A project instruction file for Gemini CLI and Gemini Code Assist, covering project rules, tools, coding preferences, and context limits.

It is for guiding work on a Flutter frontend and Rust backend, including tool use, API checks, feature-file review, and saving key decisions when context gets large.

It gives the coding assistant project-specific guidance so it can follow the repository's Dart, Flutter, and Rust practices and check the right files and versions.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00275	$0.00275
Opus 5.5	$0.00110	$0.00110
Sonnet 5.5	$0.00055	$0.00055
Haiku 4.5	$0.00028	$0.00028

Security

Grade A, and why

devoxx-2026 GEMINI.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 2mo 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.

Instructions spécifiques Gemini

Comportement attendu

Toujours expliquer ton raisonnement avant de proposer du code
Utiliser le Dart/Flutter MCP server quand disponible pour l'introspection
Préférer les solutions idiomatiques Dart (cascade notation, collection if/for)
Pour Rust, exploiter pleinement le type system (enums pour les états, From/Into pour les conversions)

Outils et contexte

Utiliser la recherche Google intégrée pour vérifier les API Flutter/Rust récentes
Ne pas supposer les versions des packages : vérifier pubspec.yaml et Cargo.toml
Quand tu travailles sur le frontend, charge les fichiers .feature avant d'écrire du code

Limites de contexte

Si le contexte devient lourd, utilise /memory add pour sauvegarder les décisions clés
Préférer travailler feature par feature plutôt que cross-cutting
Résumer les fichiers longs plutôt que de les inclure en entier

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.
