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 | $0.01397 | $0.01397 |
| Opus 5.5 | $0.00559 | $0.00559 |
| Sonnet 5.5 | $0.00279 | $0.00279 |
| Haiku 4.5 | $0.00140 | $0.00140 |
Grade A, and why
copilot-datagate 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 1mo 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 — 93 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Purpose
Queste istruzioni definiscono come Copilot deve generare codice e proporre modifiche in questo repository. L'obiettivo è coerenza, correttezza e rispetto del ruolo di security-boundary che DataGate ha tra un LLM e un database reale.
Source of Truth
- In caso di conflitto tra documentazione e codice sorgente, il codice sorgente è autorevole.
- Prima di implementare una feature, verifica i pattern esistenti nei moduli
corrispondenti (
src/policy.rs,src/query/,src/backend/,src/mcp/, ecc.). - Se rilevi drift tra istruzioni e implementazione, aggiorna questo file nello stesso lavoro.
Architettura (vedi Architecture.md per il dettaglio)
- Core layer: connessioni, read-only, schema loader, policy engine, query builder, validazione input, limiti di complessità.
- Nessun modulo può bypassare policy engine + query builder controllato per raggiungere un backend.
- I tool MCP (
src/mcp/) non parlano mai direttamente al backend: passano sempre da policy → query builder → backend.
Regole di sicurezza (non negoziabili)
- Nessun SQL libero. Ogni query deve passare dal query builder controllato
(
select,search,aggregate) e da query parametrizzate. - Read-only garantito. Nessuna operazione di scrittura (INSERT/UPDATE/DELETE/DDL) deve mai essere raggiungibile da un tool MCP o da un path di codice applicativo.
- Policy-first. Ogni operazione deve essere validata dal policy engine (tabelle, colonne, filtri, limiti di righe/complessità) prima di generare qualunque SQL.
- Nessun leak di schema. Errori e risposte non devono mai esporre stack trace, SQL grezzo, o nomi di tabelle/colonne non autorizzate dalla policy.
- Determinismo. Stessa richiesta → stessa risposta. Evitare comportamenti emergenti o dipendenti da stato nascosto.
- Limiti sempre lato server. Rate limiting, limiti di output e di complessità non vanno mai delegati solo al client/tool.
Regole di codice (Rust)
- Segui STYLEGUIDE.md: niente
unwrap()/panic!su input esterno,cargo fmt+cargo clippy -D warningspuliti prima di ogni commit. - Errori di dominio con
thiserror, errori applicativi conanyhow. - I/O asincrona con
tokio; connessioni ai backend sempre tramite pool. - Credenziali backend solo da environment variables/runtime secret store (
DB_URLoDB_*); mai password, URL con credenziali o segreti nei file del repository. - Mantieni i moduli piccoli e allineati ai confini descritti in Architecture.md; non introdurre dipendenze pesanti se non strettamente necessarie.
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.

copilot-datagate copilot-instructions.md is an instructions file published in the GitHub repository Caucus-Race/copilot-datagate (0 stars, last pushed 25d ago), licensed Apache-2.0. It adds 1,397 tokens to every session, about $0.0056 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
