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.

Security

Grade B, and why

AutoFixture.XUnit2.AutoMock AGENTS.md scanned grade B 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 5d 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.

Strips warnings and disclaimersmediumAnti-refusal

Omitting safety caveats hides risk from the user and is a common jailbreak preamble.

Enforces code style via `EnforceCodeStyleInBuild=true` and `TreatWarningsAsErrors=true`. A build that passes without warnings means all analyzers are satisfied.

AGENTS.md - AI Agent Context for AutoFixture.XUnit2.AutoMock

This file provides context for AI coding assistants (Claude Code, GitHub Copilot, OpenAI Codex, Cursor, and others) working in this repository. Read it before making any changes.

What This Project Does

C# NuGet library collection that bridges:

  • AutoFixture - generates anonymous test data automatically
  • Mocking frameworks - Moq, FakeItEasy, NSubstitute

The result: xUnit2 test attributes that auto-generate both test data and mocks in one step, eliminating boilerplate setup in unit tests.

Published NuGet packages:

  • Objectivity.AutoFixture.XUnit2.AutoMoq (uses Moq)
  • Objectivity.AutoFixture.XUnit2.AutoFakeItEasy (uses FakeItEasy)
  • Objectivity.AutoFixture.XUnit2.AutoNSubstitute (uses NSubstitute)

Core is not published standalone - it is bundled into each of the three packages above.

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.
