Phase B — doc-tester skill run
- Local docs site:

/integrations/cloud/azure/azure-ai-foundry/azure-ai-foundry-host/(the only file the PR changes) + HEAD-checks against the page's outbound internal links and the two screenshot URLs. - Result: 1 critical issue, 2 warnings, 7 passed checks (full report below).
Combined verdict: Requesting changes — Phase A finds three contradicted claims (the TypeScript asHostedAgent shape and the dashboard /liveness / /readiness URLs), and Phase B independently surfaces the same TS shape as a critical user-blocking issue plus a screenshot/prose mismatch in the dashboard section.
Inline comments are anchored to the specific PR lines below.
Phase A — Claim verdicts
Contradicted claims
The three failed claims are posted as inline review comments. In short:
- TypeScript
asHostedAgent({ project })is the wrong call shape for the renamed API onrelease/13.4. The polyglot exportAsHostedAgentForExport<T>(builder, IResourceBuilder<AzureCognitiveServicesProjectResource> project, HostedAgentOptions? options = null)(src/Aspire.Hosting.Foundry/HostedAgent/HostedAgentBuilderExtension.cs:62-67) makesprojecta required positional argument.HostedAgentOptions(HostedAgentOptions.cs:15-46) has noprojectfield. The polyglot integration test fixture confirms the canonical shape:asHostedAgent(project, { description, cpu, memory, metadata, environmentVariables })(tests/PolyglotAppHosts/Aspire.Hosting.Foundry/TypeScript/apphost.mts:113). The pre-rename TS sample worked because the priorpublishAsHostedAgent/withComputeEnvironmentexports treatedprojectas a nullable optional. The rename made it required, but the TS samples were carried over unchanged. Affects lines 400, 407, 453. - "Dashboard links for
/responses,/liveness, and/readiness" is no longer true onrelease/13.4. CurrentConfigureRunMode(HostedAgentBuilderExtension.cs:171-183) only rewrites the existinghttpendpoint URL to/responses(display text"Responses Endpoint") — no/livenessor/readinessURLs are added and there is no.WithHttpHealthCheck("/liveness")call. The source PR that drove this rename removed the commented-out health-check URL setup. The mechanical PublishAsHostedAgent → AsHostedAgent rename on line 540 carried the old prose forward.

Critical issue (Phase B)
TypeScript example for asHostedAgent shows an API shape that contradicts the C# example in the same section — section “Add a hosted agent to Azure AI Foundry” and the “Declare endpoint before AsHostedAgent” subsection.
A polyglot reader toggling between tabs sees .AsHostedAgent(project) in C# but .asHostedAgent({ project }) in TypeScript. The TS samples include no other named properties alongside project, so a new TS user has no way to discover whether the API accepts options (description, cpu, memory, env vars, metadata, etc.) and no way to validate the API shape from the docs alone. Hovering the call in the rendered Twoslash output surfaces project: any — a TS user has no way to tell whether any is intentional or a sign the types aren't resolving.
Recommended action:
- Reconcile the TypeScript shape with the C# shape on lines 400, 407, and 453.
- Show at least one additional option in the TypeScript example so users learn what else fits in the call.
Warnings (Phase B)
1. Claim about /liveness and /readiness dashboard links is not corroborated by the screenshots on the page. The prose under the first hosted-agent example (line 459, unchanged by this PR) and the recap in the "Invoke agents from the Aspire dashboard" section (line 540, changed by this PR) both promise three dashboard URLs (/responses, /liveness, /readiness). The two embedded screenshots (agent-send-message.png, agent-responses-result.png) show Send Message and the response result, but neither shows the three URLs. From the page alone a reader is told to expect something the visuals do not demonstrate. (Phase A confirms the /liveness and /readiness URLs are no longer wired up.)
2. Sibling link in the intro paragraph uses a relative path while every other internal link on the page is site-relative. The PR adds [Connect to Azure AI Foundry](../azure-ai-foundry-connect/). The relative form works (HTTP 200), but the rest of the page consistently uses fully-qualified site-relative paths. Worth normalizing for consistency.
Passed checks (Phase B)
- The PR-modified route resolves with HTTP 200 against the PR head content.
- Both screenshots referenced by the page load (HTTP 200).
- Internal links sampled from the page all resolve:
azure-ai-foundry-connect/,azure-ai-foundry-get-started/,/get-started/app-host/,/reference/cli/commands/aspire-add/. - All site-relative links on the page (except favicon/feed assets, which are intentionally extensionful) end with a trailing slash.
- The
aspire add azure-ai-foundrysnippet uses the documented short-name form. - The Pivot/PivotSelector pairing for C# / TypeScript renders correctly across the page.
- Prose ordering inside the “Add a hosted agent” section flows logically: method intro → base example → run-mode endpoint defaults → custom-port pattern → publish-mode behavior.
- The “
AddProjectcreates a default Azure Container Registry … only in publish mode” clarification aligns cleanly with the immediately precedingWithContainerRegistry(registry)example.
Knowledge gaps surfaced (Phase B)
- Polyglot binding mechanics. Evaluating whether the TS / C# shape divergence is intentional required prior knowledge of how Aspire's polyglot export attribute drives the TS shim — nothing on the page (or anything it links to) explains this. A short conceptual link from this page would let a new TS user reason about which divergences are bugs vs. design.
DEFAULT_AD_PORTabbreviation. The page introducesDEFAULT_AD_PORTwithout expanding whatADstands for. Easy fix — a parenthetical the first time it appears.
This review was produced by the hourly docs-from-code reviewer (Phase A reads microsoft/aspire@release/13.4 source of truth; Phase B runs the doc-tester skill against the locally-served PR head, blind to source code; Phase C merges and posts both).
Encoding was corrupted; reposting clean review.

The \ rontend-build\ CI is failing due to a content error in the code samples in this PR, not a flaky infrastructure issue. Retriggering the run will not resolve it. Root cause: The twoslash TypeScript block validator found 2 unexpected diagnostics in one or more code blocks:
This means a TypeScript code snippet in the PR's docs content is emitting type errors that weren't expected (not annotated with // errors\ or similar). Please review the code blocks added/modified in this PR and either fix the TypeScript errors in the examples or annotate them appropriately. cc David Fowler (@davidfowl) (original PR author) |

@davidfowl).Targeting
release/13.4based on the source PR milestone13.4(exact match onmicrosoft/aspire.dev).Why this PR is needed
PR microsoft/aspire#17669 renamed the hosted-agent builder API from
WithComputeEnvironmenttoAsHostedAgent(a breaking API removal per the public API surface file). The existing docs usedPublishAsHostedAgent(a previous name) which no longer exists in the public API. All hosted-agent code examples and prose must be updated to use the newAsHostedAgentmethod.Additionally, the PR changed the behavior of
AddProject: the default Azure Container Registry is now only created in publish mode (when deploying to Azure), not in local run mode. The docs previously stated it was always created.Changes
