Prisma ORM is a Node.js and TypeScript database toolkit that lets applications work with databases through a programming interface instead of writing every query directly in SQL. Developers use it with databases including PostgreSQL, MySQL, MariaDB, SQL Server, SQLite, MongoDB, and CockroachDB. The catalogue add-ons provide agent rules, skills, hooks, agents, and other workflows for using Prisma.
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 5.1 | $0.00000 | $0.00214 |
| Opus 5.5 | $0.00000 | $0.00086 |
| Sonnet 5.5 | $0.00000 | $0.00043 |
| Haiku 4.5 | $0.00000 | $0.00021 |
Grade A, and why
test-mocking-patterns 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.

What it actually says
Test Mocking Patterns
Type assertions in tests
Allowed in tests only:
@ts-expect-error(with a short reason)- Double casts (
as unknown as X) for mocks / dynamic proxies
Prefer unknown over any to keep the unsafe boundary explicit.
Mocking class instances
Rule: Don’t spread ({ ...instance }) class instances in tests — you’ll lose prototype methods.
const mocked = Object.create(Object.getPrototypeOf(original));
Object.assign(mocked, original, { verify: mockedVerify });
When a test mock needs a cast
- Keep the mock shape minimal (only fields you need)
- Put the cast at the boundary (return statement), not sprinkled throughout the test
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.

test-mocking-patterns is a cursor rule published in the GitHub repository prisma/orm (47,671 stars, last pushed today), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 214 tokens. 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 2026-09-03.
