Before concluding a leg is clean, also check `binlog_overview` and look for failed targets / `OnError` handlers / process-termination clues (see **Defensive Behavior** below). Only when **every** leg shows no errors **and** no failed-target/process evidence has the build itself compiled cleanly. This workflow analyses **build** failures only: a clean compile means the pipeline failure is a **non-build** failure (most often a test / Helix / publishing stage), which is out of scope. In that case **post nothing** — call `noop` with a short reason (e.g. `"Build compiled cleanly across all legs; pipeline failure is in a non-build stage (test/Helix) — out of scope for build-failure analysis."`) and stop.

Use the resolution plan to construct a concrete `suggestion` block (e.g., updating the version in `Directory.Packages.props`). - -> **Note:** The NuGet MCP server operates on the workspace's actual project files and NuGet configuration. It has access to the repository's NuGet feeds and can resolve transitive dependency chains that are impossible to reason about from error messages alone. +Notes: +- `NU1605` (downgrade): find where the lower version is pinned and raise it to satisfy the transitive requirement named in the error. +- `NU1102` / `NU1100` (not found): confirm the exact package **and version** the error names from the binlog, and note which configured feeds were searched (the `NU1102` message lists them). You have **no** network or NuGet tool, so do **not** assert whether that version exists on nuget.org or any upstream feed. Base your conclusion only on the binlog's feed/version evidence and the PR's package files: if the pin looks wrong (typo, non-existent version) relative to those files, say so; when whether the version exists upstream is the deciding factor, state that explicitly and ask a maintainer to confirm upstream availability (or run the restore locally) rather than guessing at a mirroring gap. +- If the transitive graph is too complex to resolve confidently from the error text and package files alone, say so and recommend a maintainer run the restore locally, rather than guessing. ### Step 4 — Read source context for the highest-confidence fix -For each root cause, identify the **smallest set of files** that need to change. Read those files from the workspace (paths in the errors JSON are absolute — convert with `GH_AW_WORKSPACE`). +For each root cause, identify the **smallest set of files** that need to change. The runner workspace is **not** a reliable checkout of the failing PR at `GH_AW_PR_HEAD_SHA` (the generated jobs check out the repo for agent config using the event's default ref, not the PR head), so treat the **GitHub API / `github` MCP tool at the `GH_AW_PR_HEAD_SHA` ref** as the source of truth for PR source (convert the absolute compiler paths in the binlog to repo-relative paths first) rather than reading the local workspace. - For Roslyn / C# errors: read 6 lines above and 10 lines below the reported line. - For MSBuild errors: read the offending element and the surrounding `` / `` / ``. -- For NuGet failures: read the `.csproj`, `Directory.Packages.props`, and `eng/Versions.props` rows mentioning the package.

If the source line at the reported `file:line` does not look like a plausible cause (sometimes the compiler reports the *call site*, not the *declaration site*), search the PR-changed files for the symbol named in the error message and use that as the suggestion target. ### Step 5 — Build the PR comment -Always post **exactly one** summary comment via `add_comment`. Mark it with the HTML marker `` so future runs (and humans) can identify and supersede it. The gh-aw `add-comment` config in `build-failure-analysis.md` has `hide-older-comments: true`, which collapses prior runs on update. +This step applies **only when you have confirmed a genuine build failure** (at least one leg has build errors or failed-target/process evidence). If every leg compiled cleanly, do not reach this step — `noop` silently per Step 2 instead. + +When there is a build failure, first re-verify the target revision: read PR `GH_AW_PR_NUMBER` with the GitHub `pull_requests` read tool exposed by the github MCP server (the pull-request "get"/read operation) and take `head.sha` and `merge_commit_sha`. If `head.sha` cannot be read or no longer equals `GH_AW_PR_HEAD_SHA` — or `GH_AW_PR_MERGE_SHA` is non-empty and `merge_commit_sha` is non-empty but differs from it (the base branch advanced) — the PR moved while you were downloading/analyzing, so `noop` with a short reason and stop: your inline suggestions carry no `commit_id` and would land on the wrong lines of the new diff/merge.

Analyze the binary logs of the Azure +DevOps build that just failed and produce a PR review using the safe-output +tools (a later `safe_outputs` job performs the actual GitHub write). +Do **not** try to spawn a sub-agent: the `task` tool is intentionally not +available here.

Read the agent-context environment variables: `GH_AW_BUILD_OUTCOME`, - `GH_AW_BINLOG_PATH`, `GH_AW_BINLOG_HOST_PATH`, `GH_AW_PR_NUMBER`, - `GH_AW_PR_HEAD_SHA`, `GH_AW_WORKSPACE`. + `GH_AW_BINLOG_LIST`, `GH_AW_BINLOG_DIR`, `GH_AW_BINLOG_PATH`, + `GH_AW_BINLOG_HOST_PATH`, `GH_AW_PR_NUMBER`, `GH_AW_PR_HEAD_SHA`, + `GH_AW_PR_MERGE_SHA`, `GH_AW_WORKSPACE`. 2. If `GH_AW_BUILD_OUTCOME == 'success'`, the build did not actually fail — - there is nothing to analyse. Call `noop` with the message + there is nothing to analyze. Call `noop` with the message `"Build succeeded — no analysis required."` and stop. -3. Otherwise, launch the `build-failure-analyst` agent as a **background** - task (`task` tool, `agent_type: "general-purpose"`, - `model: "claude-opus-4.6"`, `mode: "background"`). In the sub-agent prompt - include: - - All six `GH_AW_*` environment values verbatim so the sub-agent knows - which binlog to query (`GH_AW_BINLOG_PATH` is the in-container path - `/data/build.binlog` exposed by the `binlog-mcp` MCP server) and where - to post. - - A reminder that the binlog is live-queryable through the `binlog-mcp` - MCP server: the sub-agent should call MCP tools such as - `binlog_overview`, `binlog_errors`, `binlog_warnings` (and others as - needed) with `binlog_file: "$GH_AW_BINLOG_PATH"`, rather than reading - pre-dumped JSON files. - - A reminder that the parent workflow `noop`s immediately and that the - sub-agent itself is responsible for calling `add_comment` (summary) and - `create_pull_request_review_comment` (inline ```suggestion blocks). - - A reminder that `submit_pull_request_review` is **not** a safe output - for this workflow — inline comments stand alone. - -4. **Immediately after launching the background task** — do NOT wait for it - to finish and do NOT read its result — call `noop` with a brief status - message such as - `"Build-failure analyst launched in background for PR #N. It will post the analysis directly."`. - Then stop. - -> **Important**: Reading the background agent result would pull its entire -> conversation (including every binlog query and every source file it -> inspected) into your context. Do not call `read_agent` or any equivalent -> after calling `noop`. +3. Load your detailed playbook: `cat .github/agents/build-failure-analyst.agent.md` + (it is checked out with the repository config). Follow that methodology — + root-cause grouping, source-context reading via the GitHub API at + `GH_AW_PR_HEAD_SHA`, comment/suggestion formatting, and defensive behavior. + In summary: + - Iterate **every** path in `GH_AW_BINLOG_LIST` (newline-separated + in-container binlog paths, one per failed-build leg, under + `GH_AW_BINLOG_DIR` = `/data/binlogs`) and query the `binlog-mcp` MCP + server (`binlog_errors`, `binlog_overview`, `binlog_warnings`, …) with + `binlog_file` set to each leg's path — a failure usually surfaces in only + one leg, so do not analyse just the first. If no leg shows errors **and** + no failed-target/process evidence, the build compiled cleanly — the + pipeline failure is then a **non-build** (test/Helix/publishing) failure, + which is **out of scope**. This workflow analyses build failures only, so + **post nothing**: call `noop` with a short reason and stop. Do **not** + post a summary comment and do **not** invent fixes. + - Post exactly one summary via `add_comment` and any inline + `suggestion` blocks via `create_pull_request_review_comment`, **targeting + the pull request `GH_AW_PR_NUMBER` explicitly** (these workflows use + `target: "*"`, so there is no implicit "triggering PR" — pass the number + on every safe-output call). + - `submit_pull_request_review` is **not** a safe output for this workflow; + inline comments stand alone. + +4. When you have posted the analysis for a genuine build failure (or called + `noop` for a clean-compile / non-build failure), stop.
