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.
npx agentmods add instructions/azure/data-api-builder/copilot-instructionsgit clone --depth 1 https://github.com/Azure/data-api-builderWhat 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 | $0.02070 | $0.02070 |
| Opus 5 | $0.01035 | $0.01035 |
| Sonnet 5 | $0.00414 | $0.00414 |
| Haiku 4.5 | $0.00207 | $0.00207 |
Grade C, and why
data-api-builder copilot-instructions.md scanned grade C with 1 finding 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 yesterday.
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.
Reaches for credential fileshighPrivilege escalation
SSH keys, cloud credentials, git-credentials, .npmrc, /etc/shadow: reading these is how a config file becomes a credential leak.

Data API builder (DAB) - Copilot Instructions
Project Overview
Data API builder (DAB) is an open-source, no-code tool that creates secure, full-featured REST, GraphQL endpoints for databases. It's a CRUD data API engine that runs in a container—on Azure, any other cloud, or on-premises. It also supports creation of DML and Custom MCP tools to build a SQL MCP Server backed by a SQL database.
Key Technologies
- Language: C# / .NET
- .NET Version: .NET 10.0 (see
global.json) - Supported Databases: Azure SQL, SQL Server, SQLDW, Cosmos DB, PostgreSQL, MySQL
- API Types: REST, GraphQL, MCP
- Deployment: Cross-platform (Azure, AWS, GCP, on-premises)

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.

data-api-builder copilot-instructions.md is an instructions file published in the GitHub repository Azure/data-api-builder (1,503 stars, last pushed 2d ago), licensed MIT. It adds 2,070 tokens to every session, about $0.0103 per session on Opus 5. A static security scan graded it C with 1 finding (reaches for credential files). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
