Summary

src/ATProtoNet ships with <GenerateDocumentationFile>true</GenerateDocumentationFile> but emits 1114 unique CS1591 warnings ("Missing XML comment for publicly visible type or member"). Every one of them is a public API surface that arrives in a consumer's IntelliSense with an empty tooltip.

This is not a build failure — <TreatWarningsAsErrors> is deliberately false on the core project — but it is the single largest source of noise in the build (CS1591 is 1114 of the ~1120 warnings the solution produces), which means a genuinely new warning on a touched file is easy to miss.

Observed on main at v0.5.0 (fab0e9f), via:

dotnet build -p:EnableSourceControlManagerQueries=false -c Release --no-incremental

Scope

All 1114 are in ATProtoNet.csproj. The other three doc-generating projects — ATProtoNet.Server, ATProtoNet.Blazor, ATProtoNet.Aspire.Hosting — are clean, so this is contained to the core package.

Roughly 1080 are undocumented members (mostly DTO properties) and ~30 are undocumented types.

By area

Area	Warnings
`Lexicon/App/Bsky`	406
`Lexicon/Com/AtProto`	297
`Lexicon/Tools/Ozone`	202
`Lexicon/Chat/Bsky`	72
`Identity`	64
`Auth/OAuth`	58
`Lexicon/Site/Standard`	9
`Auth`, `Http`, `Serialization`	6

1044 of 1114 (94%) are in *Models.cs files — the per-Lexicon DTO files. The remaining 70 are spread thinly across Identity/ (the Did, Handle, AtUri, Nsid, Tid, Cid, RecordKey, AtIdentifier value types, 7-9 each), Auth/Session.cs, Http/AtProtoHttpException.cs, and Serialization/LexiconPlugin.cs.

Worst files

File	Warnings
`Lexicon/Tools/Ozone/Moderation/ModerationModels.cs`	124
`Lexicon/App/Bsky/Feed/FeedModels.cs`	117
`Lexicon/App/Bsky/Graph/GraphModels.cs`	115
`Lexicon/Com/AtProto/Server/ServerModels.cs`	105
`Lexicon/Chat/Bsky/Convo/ConvoModels.cs`	67
`Lexicon/Com/AtProto/Repo/RepoModels.cs`	65
`Auth/OAuth/OAuthModels.cs`	58
`Lexicon/App/Bsky/Actor/ActorModels.cs`	56

Notes on the shape of the work

The models files are not uniformly undocumented — they are partially documented, which is why this reads worse than it is. PostRecord in FeedModels.cs documents Text, Facets, Reply, Embed, and Langs but not the $type discriminator property, so a mostly-good file still contributes warnings. Any fix should preserve the existing prose rather than bulk-regenerate over it.

Most of these members map one-to-one onto fields in the upstream Lexicon JSON, which carries a description for many of them — that is the natural source of truth for the summary text rather than inventing prose. tools/ATProtoNet.LexiconGenerator already emits <summary> from Lexicon descriptions when generating C#, so there may be leverage in reusing that path for the hand-written models.

The $type discriminator properties are a large, mechanical subset: they are all the same concept and could take a single boilerplate summary.

Suggested approach

Worth deciding before anyone starts, since "document 1114 members" is not a single sitting:

Per-area, incrementally — one PR per Lexicon domain (App/Bsky, Com/AtProto, Tools/Ozone, …), which keeps diffs reviewable and lets the count drop visibly.
Non-Lexicon first — the 70 warnings outside *Models.cs (Identity/ especially, since Did/Handle/AtUri are core public types users touch constantly) are the highest value-per-edit and could be one small PR.
Once an area is clean, consider <WarningsNotAsErrors> / a targeted #pragma-free ratchet so it cannot regress — or simply flip TreatWarningsAsErrors on for the project when the count hits zero.

Acceptance

dotnet build -c Release emits zero CS1591 from ATProtoNet.csproj
No existing XML documentation is lost or degraded in the process
Ideally a mechanism that prevents the count from creeping back up

Non-goals

The 2 RZ10012 warnings in samples/ServerIntegrationSample (a missing @using for ReconnectModal) and the 2 CS1573 / 2 CS0419 warnings — unrelated, and small enough to fold into whatever touches them next.

Pushed to claude/issue-72 — open a PR.

What changed

All 1114 CS1591 warnings are gone — ATProtoNet.csproj builds clean, and so does the rest of the solution.

Documentation (1114 members, 45 files). I generated the doc comments mechanically but wrote the vocabulary by hand — a curated map of ~450 AT Protocol field semantics keyed by property name, with per-owner overrides where a bare name is ambiguous. So the summaries describe the protocol field rather than restating the C# identifier:

Cursor → "Pagination cursor; pass this back on the next request to continue where this page ended."
SwapCommit → "Compare-and-swap guard: the commit CID the repository must currently be at for the write to succeed."
FollowRecord.Subject → "The DID of the account being followed", while ModEventView.Subject → "The subject the event applies to"
$type discriminators carry the Lexicon ID they return: "The Lexicon type discriminator (app.bsky.feed.post)."
Constants render their wire value: "The com.atproto.moderation.defs#reasonSpam report reason."
The Did/Handle/AtUri/Nsid/Tid/Cid/RecordKey/AtIdentifier conversion operators and ==/!= got real docs with <param>/<returns>; Equals(object), GetHashCode, ToString, CompareTo got <inheritdoc />, which is the honest answer there.

No existing prose was lost. The diff is insert-only — 1620 insertions, 1 deletion, and that one deletion is the deliberate cref fix below. Partially-documented types like PostRecord kept every line they had; only the undocumented members gained one.

Ratchet. All four doc-generating packages now set <WarningsAsErrors>$(WarningsAsErrors);CS1591</WarningsAsErrors>. TreatWarningsAsErrors stays false, so this is narrowly scoped to undocumented public members.

Folded in the non-goals, since they were one line each and got the solution to zero warnings: the missing <param name="proxyOverride"> on XrpcClient.SendWithDPoPRetryAsync (CS1573), the ambiguous <see cref="PlcClient.SubmitOperationAsync"/> in PlcOperationBuilder (CS0419), and the missing @using ServerIntegrationSample.Components.Layout for ReconnectModal (RZ10012).

Verified

dotnet build -c Release --no-incremental (whole solution) — 0 warnings, 0 errors
dotnet test tests/ATProtoNet.Tests/ — 1103 passed, 0 failed, 5 skipped (the Aspire manifest tests, gated as usual)
dotnet pack succeeds; the emitted ATProtoNet.xml parses as XML with 2670 documented members
The ratchet actually fires: I dropped a probe file with an undocumented public class into src/ATProtoNet/, confirmed the build failed with error CS1591 on both the type and its property, then removed it

One judgement call worth flagging

The issue suggested splitting this per-Lexicon-domain across several PRs. I did it in one commit instead, because the value is concentrated in the ratchet — and the ratchet can only go in once the count is zero everywhere. The diff is large but uniform; reviewing one *Models.cs file gives you a fair sample of the other 30. If you'd rather land it in slices, say so and I'll split the branch by domain.
