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 | $0.00175 | $0.02546 |
| Opus 5 | $0.00088 | $0.01273 |
| Sonnet 5 | $0.00035 | $0.00509 |
| Haiku 4.5 | $0.00017 | $0.00255 |
Grade A, and why
azuresql-db-functions 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 3d 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.

Serverless API + event-driven on the Azure SQL Database container with Azure Functions
Build HTTP CRUD endpoints and change-driven handlers over the local Azure SQL Database container (Private Preview) using Azure Functions and the first-party Azure SQL bindings. Two capabilities:
- API: HTTP-triggered functions with SQL input and output bindings (read and upsert with no ADO.NET boilerplate).
- Event-driven (local): the SQL trigger binding fires a function when rows are inserted/updated/deleted. It is backed by Change Tracking, runs fully locally against the container, and needs no cloud services.
Event-driven note: Azure SQL Change Event Streaming (CES) is the cloud path for streaming row changes, and it cannot run against the local container (it is unsupported on the Linux engine and streams only to Azure Event Hubs public endpoints). Locally, use the SQL trigger below. See references/event-driven.md.

What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

azuresql-db-functions is a skill published in the GitHub repository microsoft/azure-sql-database-container (16 stars, last pushed yesterday), licensed MIT. It adds 175 tokens to every session and 2,546 once invoked, about $0.0009 per session on Opus 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 2026-08-30.
