… reasoning Apply the Data vs. Reasoning Boundary pattern: - Script emits [CI_ANALYSIS_SUMMARY] JSON block with structured facts (totalFailedJobs, failedJobNames, knownIssues, prCorrelation, recommendationHint) - Removed 47-line if/elseif recommendation chain producing canned prose - Added 'Generating Recommendations' section to SKILL.md with decision table - Updated 'Presenting Results' to reference JSON summary flow - Agent now reasons over structured data instead of parroting script output Tested with Claude Sonnet 4 and GPT-5 against PR dotnet#124232 — both rated JSON completeness 4/5 and generated better recommendations than the old heuristic.

## Problem After UseMonoRuntime was removed from in-tree wasm props (PR #121789 by @maraf), browser-wasm test restores fail with NU1102 (package not found). The `RestorePackage` target in `build.proj` runs `dotnet restore` for test dependency projects. These projects use `Microsoft.NET.Sdk` (not the WebAssembly SDK), so `UseMonoRuntime` is not set. Without it, the newer SDK tries to download `Microsoft.NETCore.App.Runtime.browser-wasm` (CoreCLR pattern) or `Microsoft.NETCore.App.Runtime.Mono.browser-wasm` from NuGet — packages that don't exist for .NET 11. The test restore doesn't need runtime or targeting packs from NuGet — those come from the local build and are wired up during the test build step. However, `EnableRuntimePackDownload=false` and `EnableTargetingPackDownload=false` were only passed conditionally (when `UseLocalAppHostPack=true`), and browser-wasm sets `UseLocalAppHostPack=false`. ## Fix Unconditionally pass `-p:EnableRuntimePackDownload=false -p:EnableTargetingPackDownload=false` to the test dependency restore command. This fixes both Mono and CoreCLR browser-wasm configurations since neither needs pack downloads during restore. ## Context - Root cause PR: #121789 (Remove duplicated UseMonoRuntime=true from SDK) - Follow-up pattern: #123181 (Added RuntimeFlavor=Mono to perf pipeline) - Affected codeflow PR: #124232 cc @maraf @akoeplinger

…on guides (#124240) ## ci-analysis: structured output, MCP integration, and deep investigation guides ### Changes to `Get-CIStatus.ps1` (+216/-132) - **Add `[CI_ANALYSIS_SUMMARY]` JSON block** — structured summary emitted at end of script with all key facts (builds, failed jobs, known issues, PR correlation, recommendation hint) - **Replace 47-line if/elseif recommendation chain** with a single `recommendationHint` field in JSON (one of: `BUILD_SUCCESSFUL`, `KNOWN_ISSUES_DETECTED`, `LIKELY_PR_RELATED`, `POSSIBLY_TRANSIENT`, `REVIEW_REQUIRED`, `MERGE_CONFLICTS`, `NO_BUILDS`) - **Add `failedJobDetails` to JSON** — per-job `errorCategory` (test-failure, build-error, test-timeout, crash, tests-passed-reporter-failed, unclassified), `errorSnippet`, and `helixWorkItems` - **Add `failedJobDetailsTruncated`** — boolean flag indicating when `-MaxJobs` cap means `failedJobDetails` is incomplete vs `failedJobNames` - **Add top-level `knownIssues`** from Build Analysis (not per-job — Build Analysis reports at the PR level, not per-job) - **Add timeout pattern** to `Format-TestFailure` — catches `Timed Out (timeout` that was previously invisible - **Show log tail in PR mode** when no failure pattern matches (Helix Job mode already did this) - **Add accumulation variables** for cross-build aggregation (`totalFailedJobs`, `totalLocalFailures`, `lastBuildJobSummary`) - **Fix early-continue scoping bug** — job summary computation was at end of build loop, after 3 `continue` paths that skipped it - **Fix empty array falsy check** — `if ($listFiles)` → proper count check - **Fix `mergeable_state` trimming** — `gh api --jq` output trimmed to prevent whitespace comparison failures - **Remove interpretive prose** — "These failures are likely PR-related" moved from script to agent reasoning - **Fix empty catch** — merge state error now logged via `Write-Verbose` ### Changes to `SKILL.md` (+97/-144, net reduction) - **Add Step 0: Gather Context** — PR type classification table (code, flow, backport, merge, dependency update) - **Add Step 3: Verify before claiming** — systematic checklist - **Add build progression analysis** (Step 2, item 4) — comparing pass/fail across PR builds to narrow down which commit introduced a failure - **Add prior-build mismatch detection** (Step 2, item 6) — ask user when they reference jobs not in current results - **Document `failedJobDetails`** — per-failure error categories in Interpreting Results - **Add Build Analysis check status enforcement** — red check means unaccounted failures exist, never claim "all known" when it's red - **Add timeout recovery workflow** — explicit guidance for verifying timed-out builds have passing Helix results via `hlx_status` - **Add crash/canceled job recovery procedure** — step-by-step using `hlx_batch_status`, `hlx_files`, `hlx_download_url` to recover results from crashed Helix work items - **Fix MCP tool references** — use canonical short-form tool names consistently - **Condense anti-patterns** — tighter, more targeted, near relevant steps - **Net token reduction** — despite adding new content, SKILL.md shrank from ~4.6K to ~3.5K tokens ### New reference files - `references/azure-cli.md` — Azure CLI deep investigation guide - `references/binlog-comparison.md` — binlog comparison workflow - `references/delegation-patterns.md` — subagent delegation patterns (5 patterns including parallel artifact extraction and canceled job recovery) - `references/build-progression-analysis.md` — commit-to-build correlation using `triggerInfo.pr.sourceSha`, SQL-based progression tracking, MCP-first with AzDO MCP tools as primary ### Updated reference files - `references/manual-investigation.md` — fix nonexistent `msbuild-mcp analyze` tool refs, use real `mcp-binlog-tool-*` tools ### Design principles - **Data/reasoning boundary**: Script emits structured JSON facts → agent synthesizes recommendations. No more canned prose from the script. - **MCP-first**: AzDO MCP tools (`get_builds`, `get_build_log_by_id`) and Helix MCP tools (`hlx_status`, `hlx_logs`) positioned as primary, CLI/script as fallback. - **Token budget**: Orchestrating SKILL.md kept within 2K-4K token budget by extracting depth to `references/`. - **SQL for structured investigations**: Build progression tracking uses SQL tables to persist SHAs across context, enabling queries for pass→fail transitions and target branch movement. ### Testing - Multi-model subagent testing (Sonnet 4 + GPT-5 + Opus 4.5) — two review rounds with findings addressed - Live MCP integration test confirmed `hlx_status`, `hlx_logs`, `get_builds`, `get_build_log_by_id` all work - Real-world validation against PRs #123245, #123883, #124125, #124232

@akoeplinger to get back to you on this, it appears that the original problem was this forward flow that didn't make the correct change: dotnet/dotnet#4680
After investigating I saw that it's another instance of the reverts problem, but this time in the opposite direction code path, where we didn't think these could happen, but basically it's a similar thing with the merge bases we we're hitting until recently.
We'll do our best to fix it as soon as possible

The previous fix (PR #124288) made EnableTargetingPackDownload=false and EnableRuntimePackDownload=false unconditional for all platforms. This broke coreclr/NativeAOT/Libraries test restores that need those packs from NuGet. Fix: Add 'or TargetOS==browser' to the existing UseLocalAppHostPack condition instead of making the flags unconditional. This fixes browser-wasm NU1102 while preserving original behavior for all other platforms.

PR #124288 moved EnableTargetingPackDownload=false and EnableRuntimePackDownload=false from conditional (only when UseLocalAppHostPack=true) to unconditional on the DotnetRestoreCommand in src/tests/build.proj. This meant all platforms — coreclr, NativeAOT, Mono on linux/windows/osx — were told to skip runtime and targeting pack downloads during test restore, even ones that actually need those packs from NuGet.

Fix (commit `1de8519`)

Instead of making the flags unconditional, I added or '$(TargetOS)' == 'browser' to the existing UseLocalAppHostPack condition:

<!-- Before (broken): unconditional on DotnetRestoreCommand -->
-p:EnableTargetingPackDownload=false -p:EnableRuntimePackDownload=false

<!-- After (fixed): conditional, same as original + browser-wasm -->
<_ConfigurationProperties Condition="'$(UseLocalAppHostPack)' == 'true' or '$(TargetOS)' == 'browser'">
  $(_ConfigurationProperties) -p:EnableAppHostPackDownload=false -p:EnableTargetingPackDownload=false -p:EnableRuntimePackDownload=false
</_ConfigurationProperties>

This preserves the original behavior for all other platforms while fixing the browser-wasm NU1102 issue.

Suggestion

We should review whether this is the right long-term approach. The underlying issue is that after UseMonoRuntime was removed from in-tree wasm props (#121789), browser-wasm test restores try to download runtime packs that don't exist on NuGet. The TargetOS==browser condition works for now, but there may be a more principled way to handle this — perhaps the wasm SDK targets should set UseLocalAppHostPack or the equivalent pack download properties directly, rather than relying on build.proj to special-case it.

Something here broke bootstrapping for the community-supported platforms, but I'm not sure what.
