Healthie.NET.AI

▶ Live demo — healthie.compiletheory.com — a read-only Healthie.NET dashboard watching real status pages (Anthropic, OpenAI, GitHub, Cloudflare, and more), built from these packages.

Explains what a pulse checker's recent history shows: whether it is failing consistently or intermittently, when it started, and what the errors point to. Provider-agnostic -- it depends on Microsoft.Extensions.AI.Abstractions and nothing else, so the model is your choice.

Installation

dotnet add package Healthie.NET.AI

Usage

using Healthie.AI;

// Anthropic, OpenAI, Azure OpenAI, or a local model via Ollama -- this package depends on none of them.
builder.Services.AddSingleton<IChatClient>(
    new AnthropicClient().AsIChatClient("claude-opus-4-8"));

builder.Services.AddHealthieAI();

Then ask it about a checker:

var diagnosis = await diagnostician.DiagnoseAsync("MyApp.Pulses.DatabasePulseChecker");

Console.WriteLine(diagnosis.Summary);
Console.WriteLine($"Failure rate rose: {diagnosis.Anomaly.IsAnomalous}");

Key Types

Type	Description
`IPulseDiagnostician`	`DiagnoseAsync(name)` returns a `PulseDiagnosis` for one checker.
`PulseDiagnosis`	The checker's `Name`, a plain-English `Summary`, and an `Anomaly` report.
`AnomalyReport`	`IsAnomalous`, `RecentFailureRate`, `EarlierFailureRate`.
`StartupExtensions.AddHealthieAI()`	Registers `IPulseDiagnostician`. Requires an `IChatClient` in DI.

The Anomaly Report Is Not a Model Call

Anomaly compares the recent failure rate against the earlier one arithmetically, from the checker's own history. It is deterministic and testable, and it is worth trusting on its own -- including when no model is configured to write the summary.

What Leaves Your Process

Diagnosing a checker sends its name, its health, and the messages its checks reported to whichever model you configured. Those messages are written by your own checkers, which is a good reason to keep credentials out of check results. This package never mutates state.

You May Not Need This

If your only consumer is an AI agent, use Healthie.NET.Mcp instead: an agent talking to the MCP endpoint can read get_check_history and reason about it itself. This package is for the surfaces where there is no model in the loop -- a REST response, a dashboard, an alert.

Twenty packages was too many, and two of them had no business being separate. This release fixes
that without breaking anything: **an application on 4.0.0 upgrades by changing nothing.**

### Added

- **`Healthie.NET`**, the package to install first. It carries no code of its own, only a dependency
on `Healthie.NET.DependencyInjection`, so it is one install and one dependency rather than a
bundle -- no provider, scheduler or UI framework arrives with it. The name people guess did not
exist before, and the actual entry point was called `DependencyInjection`, which reads like
plumbing rather than the way in.
- **Uptime reporting and leader election are in the core package.** `AddHealthieUptime()` and
`AddHealthieLeaderElection()` need nothing else installed. Both stay opt-in: nothing runs until
you call them.

### Deprecated

- **`Healthie.NET.Uptime`** and **`Healthie.NET.LeaderElection`**. Neither carried a third-party
dependency, so keeping them separate cost two installs and saved nothing -- the provider packages
exist to keep Npgsql or Temporalio off machines that do not use them, and these two were not
providers.

**Nothing breaks.** Both packages are still published, now as assemblies of type forwards, so an
application that references either keeps compiling *and* keeps running untouched. That is what
makes this a minor release: moving a type between assemblies is a binary break the compiler cannot
see, because source keeps building and only the runtime finds out. Remove the reference whenever it
suits you; neither package will gain features.

### Fixed

- **The sample Dockerfiles took their .NET base images by mutable tag.** A tag is a different image
next week, so the build that passed review is not the build that ships. Both are pinned by digest,
which Dependabot updates the way it updates a package version. Closes four OpenSSF Scorecard
*Pinned-Dependencies* findings.

### Security

- **An Azure CosmosDB key committed in May 2025 was confirmed dead and the alert closed.** It had
already been removed from the working tree; the account it belonged to no longer exists in the
owning tenant, verified by enumerating every Cosmos account across that tenant's subscriptions, so
the key authenticates to nothing. It remains in history at `ee0c78e`, inert.
- **Stray screenshots can no longer be committed.** Root-level PNGs are ignored, scoped to the root
so the images the docs and samples genuinely ship are untouched.
