From ea2bcc59cf8d2177942b3114c0d1b46f24a6c83c Mon Sep 17 00:00:00 2001 From: Shane Neuville Date: Fri, 15 May 2026 12:04:11 -0500 Subject: [PATCH 01/15] Add labeler evals and fix Handlers/*/Android/ rule gap Add tests/eval.yaml with 10 scenarios covering: - Platform label detection (.android.cs, .ios.cs dual-label, .windows.cs) - Area label detection (Shell, CollectionView, tooling, Essentials) - Cross-platform PRs (no platform labels) - Noop scenarios (automated merge PRs) - Prompt injection resistance - PR-specific status label caveat (no s/needs-info on PRs) Fix rule gap: Handlers/*/Android/ paths were not matched by the platform table, causing CollectionView Android handler PRs to miss the platform/android label.

Root cause: `checkout: false` in the frontmatter skipped the default `actions/checkout`, but the gh-aw-injected `Checkout PR branch` step still ran on PR events and tried to `git fetch` against a directory with no `.git`. Pattern in the run history (last 20 runs): - All `issues` events: success (PR-branch checkout is conditional, skipped) - All `workflow_dispatch` events: success (PR-branch checkout skipped) - All `pull_request_target` events: failure (PR-branch checkout runs, fails) Removing `checkout: false` makes gh-aw inject `actions/checkout` (base ref, read-only) before `Checkout PR branch`, which then succeeds because there is now a `.git` to fetch into. Security note: gh-aw emits a "pull_request_target with checkout" warning. The risk is accepted because: - The agent job permissions are read-only (`contents: read, issues: read, pull-requests: read`) - All writes happen through the sandboxed safe-output job (capped at one `add_labels` call) - gh-aw's "Restore agent config folders from base branch" step replaces any `.github/` or `.agents/` content from the PR with the trusted base-branch version before the agent runs - The agent only inspects file paths/contents via MCP and never executes scripts from the PR working tree Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> --- .github/workflows/agentic-labeler.lock.yml | 56 +++++++++++++++++----- .github/workflows/agentic-labeler.md | 1 -

Found three real gaps: 1. **`area-infrastructure` rule missing** — `[dnceng-bot]` branch-mirroring issues were getting noop'd by some runs of the skill and labeled `area-infrastructure` by others. The label exists ("CI, Maestro / Coherency, upstream dependencies/versions") and is the right answer. Same inconsistency hit PRs that touch only `.github/workflows/`, `.github/skills/`, `.github/scripts/`, `eng/pipelines/`, or `eng/common/` — some runs picked `area-tooling`, some noop'd. Now codified as a single rule. 2. **`area-maps` was invented** — PR #35476 (Android map fix) got the non-existent label `area-maps` because the agent extrapolated from the general `area-controls-` rule and shortened it. The real label is `area-controls-map`. Added an explicit list of the common control labels that don't match the obvious short form (`Map` → `area-controls-map`, `Window` → `area-controls-window`, `WebView` → `area-controls-webview`, `HybridWebView` → `area-controls-hybridwebview`) with a "never invent shorter aliases" guardrail. 3. **dnceng-bot codeflow issues being noop'd** — added an explicit anti-noop callout in the "When to noop" section so they get `area-infrastructure` instead. Verified the fixes by re-running the skill against the 8 misclassified items; all 8 now produce the correct labels. Added 4 new eval scenarios covering these patterns: - `[dnceng-bot]` codeflow issue → area-infrastructure (not noop) - Workflow-only PR → area-infrastructure - Skill-file PR → area-infrastructure (not area-tooling) - Maps PR → area-controls-map (not invented area-maps) Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> --- .github/skills/agentic-labeler/SKILL.md | 7 ++- .../skills/agentic-labeler/tests/eval.yaml | 52 +++++++++++++++++++ 2 files changed, 58 insertions(+), 1 deletion(-) diff --git a/.github/skills/agentic-labeler/SKILL.md b/.github/skills/agentic-labeler/SKILL.md index 5ab7247a9dce..5bdaf9dc0d38 100644 --- a/.github/skills/agentic-labeler/SKILL.md +++ b/.github/skills/agentic-labeler/SKILL.md @@ -31,7 +31,7 @@ Labeling rules for the [dotnet/maui](https://github.com/dotnet/maui) repository.

The previous commit added a rule that explicitly says workflow-only PRs should get `area-infrastructure` (not `area-tooling`), making this eval scenario contradict the very rule it was supposed to validate. Renamed to 'Infrastructure area - CI workflow file deletion' and updated the assertions to expect `area-infrastructure` and NOT `area-tooling`. 2. **(2/3) Noop regex matched too loosely** The patterns at lines 100 and 181 included bare `skip` and bare `no action`, which would match agent commentary like 'applied area-infrastructure. This requires no action from the maintainer.' — producing a false-positive noop signal even when the agent applied labels. Replaced bare `skip` → `skip.+label` (line 181 only — line 100 already had this) and bare `no action` → `no.+action.+(needed|required|appropriate|necessary)` on both lines. Verified against 5 legitimate noop phrasings and 2 false-positive scenarios: the tightened patterns reject the false positives while still matching all legitimate noop output. 3. **(2/3) 'touching only' qualifier ambiguous for mixed PRs** The `area-infrastructure` rule said 'PRs touching only ... infra files → area-infrastructure', which didn't address PRs that mix infra and product-code changes. An empirical check showed ~17% of recent PRs in dotnet/maui mix infra+src paths, but `area-infrastructure` is currently applied sparingly (mostly to infra-primary work, not every PR that touches an infra file). Added a tiebreaker: if the PR is dominated by infra changes with incidental product edits, apply `area-infrastructure` alongside any relevant product area label; if the product change is the focus and infra is incidental, prefer the product area label and omit `area-infrastructure`. Discarded findings (low confidence after consensus rounds): - Token-in-.git/config persistence (security): gh-aw framework concern, not introduced by this PR; cleanup runs before the agent executes; agent token is read-only scoped. - Hardcoded PR/issue numbers in evals: known eval-design trade-off. - `output_not_contains: 'platform/'` brittle: substring is acceptable given that all platform/* labels share the prefix. - Dependency-bump noop timing edge case: rule is correct as stated. - Missing iOS/Windows handler subdirectory patterns: existing extension patterns cover them in practice.

Changes: 1. eval.yaml:75-76 — Add 'output_not_contains: platform/' assertion to the 'Infrastructure area - CI workflow file deletion' scenario (3/3 after dispute). The rubric said no platform/* labels should appear, but no deterministic assertion enforced it. A hallucinated platform/android would have passed all hard assertions. Matches the pattern already used by the parallel 'Workflow-only PR gets area-infrastructure' scenario. 2. eval.yaml:184 — Tighten 'no additional' in dep-bump noop regex (2/3: Opus + Sonnet). Bare 'no additional' would false-positive against agent output like 'Applied area-X. No additional context provided.' Tightened to 'no additional.+(label|action|change)' so the substring must be followed by label/action/change context. 3. eval.yaml:104,184 — Expand both noop regexes with additional legitimate noop phrasings (2/3: Opus + Codex): nothing.+label, will not.+label, existing.+labels?.+(sufficient|enough). Also unified the 'not.+applicable' and 'should not.+label' alternatives across both automated-merge and dep-bump regexes. Validated with Python re.IGNORECASE against 15 true-positive and 4 false-positive phrasings. 4. SKILL.md:47 — Add 'when these are the primary subject of the PR; see Mixed PRs below' qualifier to the area-infrastructure header (2/3 after dispute: Sonnet + Codex). The unconditional header could be interpreted as conflicting with the Mixed PRs tiebreaker on line 50 for PRs that touch both infra and product code. The qualifier forward-references the tiebreaker explicitly. Round 2 findings NOT applied: - Token cleanup 'continue-on-error: true' in lock.yml (1/3, Codex only; same finding was raised AND discarded in round 1 — gh-aw framework concern, not introduced by this PR). - 'Mixed PRs' tiebreaker has no eval coverage (1/3, Sonnet only; meaningful to add but requires real PRs that exercise both branches — deferred to follow-up).

Per the multi-round self-correction rule, each was auto-elevated to 2/3+ consensus once the introducing round was identified. Changes: 1. eval.yaml:109,189 — Revert two round-2 noop regex additions (3/3 unanimous on the more egregious; 2/3 on the second): - Removed 'will not.+label' — matches legitimate non-noop output like 'Applied area-X. I will not label platform/* because no platform files changed.' (false-pass on actual label application). - Removed 'existing.+labels?.+(sufficient|enough)' — matches negated/partial phrasings like 'existing labels are NOT sufficient, adding area-x' or 'The existing label area-infrastructure is sufficient, adding t/enhancement.' (false-pass when agent adds a label and references existing labels in explanation). The kept noop regex alternatives all require label-context (e.g., 'skip.+label', 'no.+action.+(needed|...)', 'already.+label') which makes them substantially harder to false-positive. Validated with Python re.IGNORECASE: all 8/10 true-positive phrasings still match; all 3 false-positive phrasings now rejected. 2. eval.yaml:75-82,223-230 — Replace 'output_not_contains: platform/' with specific platform labels (2/3 consensus): - Bare 'platform/' substring is too broad — substring match against the FULL output. Correct agent output like 'No platform/* labels needed since workflow files are not platform-specific' would fail the assertion because the substring 'platform/' appears in the explanatory text. - Replaced with: platform/android, platform/ios, platform/macos, platform/windows — labels an agent would only print when actually applying them. Matches the pattern used elsewhere in eval.yaml (lines 47-53, 89-93, etc.). - Applied to both the round-2 'Infrastructure CI workflow deletion' scenario AND the pre-existing 'Workflow-only PR' scenario which had the same pattern. Findings NOT applied this round: - 'nothing.+(appl|label)' false-positive (Sonnet 1/3) — the pre-existing 'nothing.+appl' has the same theoretical issue; the '|label' extension only marginally expands the surface area. Tightening would require restructuring the whole pattern. - '[dnceng-bot]' rule nesting under 'primary subject' qualifier (Sonnet 1/3) — minor wording concern; the dnceng-bot sub-bullet itself explicitly says 'do not noop these' which is unconditional enough to override any qualifier inheritance.

The PR-specific caveat only excluded these on PRs, not on issues.

They are consumed by the `agentic-labeler` gh-aw workflow and can also be used standalone for batch evaluation or interactive labeling. +## 🚨 Scope: `area-*` and `platform/*` ONLY + +The labeler applies **only two label families**, and nothing else: + +1. **`area-*`** — derived from the subject matter (control name, area like layout / navigation / xaml / infrastructure / etc.). +2. **`platform/*`** — derived from changed-file platform conventions on PRs, or from explicit platform mentions on issues. + +**The labeler must NOT apply any other label, ever.** Specifically, **do not** apply: + +- `t/*` (kind: `t/bug`, `t/enhancement ☀️`, `t/docs 📝`, `t/breaking 💥`, `t/native-embedding`, `t/desktop`, `t/a11y`, etc.) — the issue/PR author or other automation owns these. +- `i/*` (indicators: `i/regression`, etc.) — set during triage based on investigation, not initial content. +- `s/*` (status: `s/needs-info`, `s/needs-repro`, `s/needs-verification`, `s/needs-attention`, `s/triaged`, `s/verified`, `s/no-repro`, `s/not-a-bug`, `s/duplicate 2️⃣`, `s/pr-needs-author-input`, etc.) — managed by `dotnet-policy-service[bot]` and human triagers. +- `p/*` (priority: `p/0`, `p/1`, `p/2`, `p/3`) — set by maintainers. +- `partner/*` (e.g., `partner/syncfusion`) — set by partner-tracking automation. +- `perf/*` (e.g., `perf/memory-leak 💦`) — set during perf investigation. +- `backport/*`, `regressed-in-*`, `version/*` — set during triage / release management. +- `untriaged`, `:watch: Not Triaged` — applied by repo automation on issue open. +- Anything else that is not literally an `area-*` or `platform/*` label. + +If the only labels that clearly apply are not `area-*` or `platform/*`, **noop** instead — see the noop section below. + +If neither an `area-*` nor a `platform/*` label clearly applies, **noop**. + ## Label discovery - Fetch the current list of labels using the `list_label` MCP tool (provided by the `labels` toolset). Note the **singular** name — it is `list_label`, not `list_labels`. -- **Important pagination caveat:** the `list_label` tool only returns the first ~100 labels (no pagination). This repo has ~440 labels, so many `area-*`, `platform/*`, and status labels will be missing from the listing. If you have a strong candidate label name in mind that isn't in the listing, **verify it exists** with the `get_label` tool before adding it. The label families enumerated below (`area-*`, `platform/*`, `t/*`, `s/*`, `i/*`, `p/*`) are reliable guides; use `get_label` for anything else. -- You may apply **any** existing label, not just `area-*` and `platform/*`. Examples of other useful label families that exist in this repo (with **exact** names — emoji suffixes are part of the label and must be matched verbatim): - - **Kind:** `t/bug`, `t/enhancement ☀️`, `t/docs 📝`, `t/breaking 💥`, `t/native-embedding`, `t/desktop`, `t/a11y` - - **Issue-content signal:** `i/regression` — only when the reporter explicitly states the bug is a regression from a prior version (e.g., the issue template's "Is this a regression" answers "Yes" or the body explicitly says so). Do not infer regressions from version numbers alone. -- **Triage / workflow labels are managed by repo automation and human triagers — the labeler must NEVER apply any of these, on issues or PRs:** - - `untriaged`, `:watch: Not Triaged` — applied by repo automation on issue open. - - `s/needs-info`, `s/needs-repro`, `s/needs-verification`, `s/needs-attention`, `s/triaged`, `s/verified`, `s/no-repro`, `s/not-a-bug`, `s/duplicate 2️⃣`, `s/pr-needs-author-input` — managed by `dotnet-policy-service[bot]` and human triagers as part of the triage workflow. - - `p/0`, `p/1`, `p/2`, `p/3` — priority is set by maintainers, not derivable from initial content. - - These rules apply to **both** issues and pull requests. The labeler's job is to assign content-derived labels (`area-*`, `platform/*`, `t/*`, `i/regression`) only — leave everything else for triagers and automation. -- Do **not** create new labels.

Mirrors the Android row's handler-subdirectory pattern. iOS-directory row maps to platform/ios ONLY (not dual with platform/macos) because handler /iOS/ directories compile for iOS TFM only, unlike the *.iOS.cs file-extension pattern which compiles for both iOS and MacCatalyst. - eval.yaml PR #35461 scenario: rename to flag scope-restriction intent, add platform/android positive assertion (the PR touches Android files) and forbidden-label negatives for i/regression, partner/syncfusion, t/bug — those labels already exist on the PR but our labeler must NOT apply them. - eval.yaml PR #35385 scenario: add platform/macos and platform/windows assertions. The PR touches Platform/Windows/, Platform/Android/, and *.iOS.cs files — that last one triggers BOTH platform/ios AND platform/macos per our file-extension rule. - eval.yaml XAML scenario: rename 'issue' -> 'PR' (prompt targets a PR). - workflow.md frontmatter description: update from generic 'appropriate labels chosen from the existing repository label set' to explicitly state 'area-* and platform/* ONLY, does NOT apply triage, status, priority, type, severity, partner, regression, or any other label families'. Locked-yml regenerated by gh aw compile. Adversarial review findings deliberately NOT applied: - (?i) regex prefix: invalidated — skill-validator already passes RegexOptions.IgnoreCase and StringComparison.OrdinalIgnoreCase, so case is handled at the framework level. - output_not_contains 'area-' / 'platform/' on noop scenarios: too risky — agent prose may legitimately reference these prefixes when explaining why no labels apply. - Issue #35448 prompt change: existing-label contamination is a framework limitation (substring match in prose); not worth a scenario-level fix.

(2/3) Stale doc rationale on roles: all comment — implied agent has no filesystem access, but checkout: false was removed in 33a15f11cb so the agent CAN read workspace files. Real protection is the gh-aw restore_base_github_folders.sh step that restores .github/ from the base branch AFTER the PR-branch checkout. Updated the comment to describe the actual trust model (PR-branch checkout DOES happen; .github/ is restored from base; agent has no exec/shell tools; safe output is add_labels max=1). 2. (2/3) Noop scenarios lack negative label assertions — both noop scenarios (automated merge PR #35464, dependency bump PR #35453) only asserted that a noop-like phrase appeared. An agent that applies a label and ALSO says 'no additional labels' would pass. Added explicit output_not_contains for platform/* (and area-infrastructure for the automated-merge case) to catch this regression. 3. (1/3) Headline /Handlers/*/Android/ rule fix has no test — the PR title is literally about this rule gap, but no scenario tests a path like src/Controls/src/Core/Handlers/Items/Android/Adapters/*.cs (no .android.cs extension). Added scenario for PR #35000 which touches exactly that path, asserting platform/android + area-controls-collectionview and forbidden negatives. 4. (1/3) SKILL.md 'do not match bare /Android/' caveat could read as conflicting with the /Handlers/*/Android/ table entry. Rephrased to explicitly defer to the table — bare segments are only ignored if they don't match any pattern in the table. Reviewers explicitly used gh-aw-guide context: cited compiler warnings, restore_base_github_folders.sh, --add-dir GITHUB_WORKSPACE, lock.yml internals, safe-outputs max enforcement. Confirmed checkout: false removal is defensible given the actual trust boundaries.

Resolved by merging origin/main, which picked up #35174 — Jakub Florkowski's intentional revert of those model IDs back to claude-opus-4.7 + gpt-5.5 because gemini-3-pro-preview is not registered in the Copilot CLI task runtime. The pr-review/SKILL.md change in this PR's diff was just staleness — main has the right values now and the merge commit brings them in. B) [2/3 ⚠️] No eval scenario tested the most subtle platform rule: paths under /Platform/iOS/ or /Handlers/*/iOS/ should apply platform/ios ONLY (not platform/macos), unlike .ios.cs file extension which applies BOTH. An agent applying both platform/ios + platform/macos for an iOS-directory-only PR would have passed every existing eval. Added new scenario using PR #34672 (single file: src/Core/src/Platform/iOS/ MauiScrollView.cs) asserting platform/ios + area-controls-scrollview and output_not_contains for platform/macos, platform/android, platform/windows, partner/syncfusion, community ✨. C) [2/3 💡] Prompt-injection scenario (issue #35312) had only output_not_contains assertions. An agent that completely noops or returns empty output would pass. Added output_contains: platform/windows (the issue title literally starts with [Windows] and the content is a Windows Shell flyout regression) so the assertion catches a noop-instead-of-labeling failure. D) [1/3 ⚠️] iOS extension scenario (PR #35445) asserted platform/ios + platform/macos but had no negative assertion for platform/android or platform/windows. Added output_not_contains for those — an agent that over-labels all four platforms would have passed before. E) [1/3 ⚠️] Windows scenario (PR #35458) asserted only platform/windows with no area-* and no non-Windows-platform negatives. Added output_contains: area-controls-collectionview (the changed file is ItemsViewHandler.Windows.cs) and output_not_contains for the other 3 platforms and partner/syncfusion. Notable discoveries during this round: - The gh-aw-guide skill detection path in ~/.agents/skills/generic-adversarial-pr-reviewer/SKILL.md continues to fire correctly — all 3 reviewers used gh-aw-aware reasoning (none re-flagged checkout: false removal or roles: all as bugs). - Eval scenario count increased from 20 → 21 (new iOS-dir-only scenario). - lock.yml unchanged (no workflow.md frontmatter changes); only eval.yaml modified in this commit.
