Reins.Analyzers

Compile-time guardrails for .NET AI agent code. Reins is a Roslyn analyzer + code fix library that catches security, reliability, and cost mistakes in code built on the Microsoft Agent Framework (Microsoft.Agents.AI) and the Microsoft.Extensions.AI IChatClient abstractions — before the code ever calls a model.

Reins is a compile-time complement to runtime governance tooling: runtime guardrails stop a bad request in production; Reins stops the bug from being merged.

Install (30 seconds)

<PackageReference Include="Reins.Analyzers" Version="0.1.0" PrivateAssets="all" />

That's it. Reins is a development dependency — it adds nothing to your application's output or its dependency graph. Projects that don't reference an AI agent framework pay zero analysis cost.

Rules

ID	Category	Severity	Rule
REINS0001	Reliability	Warning	CancellationToken not forwarded to agent invocation
REINS0002	Security	Error	Hardcoded credential in AI client construction
REINS0003	Cost	Warning	Model invocation inside a loop
REINS0004	Reliability	Warning	Unbounded agentic loop
REINS0005	Reliability	Suggestion	Agent invocation without timeout linkage
REINS0006	Security	Warning	Tool method with raw string parameter lacking validation
REINS0007	Observability	Info	Agent constructed without OpenTelemetry instrumentation
REINS0008	Cost	Suggestion	Conversation history grown in loop without reduction

Severity philosophy

Precision over recall. A noisy analyzer is a dead analyzer:

Rules that detect a definite defect (hardcoded credentials) default to Error.
Rules with high-confidence heuristics default to Warning.
Rules based on the absence of something that may legitimately live elsewhere (timeouts in Polly, OTel in DI) default to Suggestion/Info and are documented as opt-in.

Every rule doc has a "Known false positives" section. A rule with more than a 2% false-positive rate on real code gets pulled or downgraded.

Tune severities per repo via .editorconfig:

dotnet_diagnostic.REINS0007.severity = warning   # opt in harder to OTel
dotnet_diagnostic.REINS0003.severity = none      # this repo batches deliberately

See docs/configuration.md for .editorconfig recipes and CI/SARIF integration.

Building

dotnet build -warnaserror
dotnet test
dotnet pack -c Release

The samples/Reins.Sample.Agent project intentionally violates every rule and doubles as an integration test.
