From c89f4721c3c83b5e4645a366cff6e44d2a699b21 Mon Sep 17 00:00:00 2001 From: Shane Neuville <5375137+PureWeen@users.noreply.github.com> Date: Mon, 15 Jun 2026 17:49:01 -0500 Subject: [PATCH 01/23] Add Vally spike spec + fold in PR #35925 SKILL.md fix MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Commit 0 of the legacy skill-validator → @microsoft/vally-cli migration. ## What this commit does 1. **Throwaway spike spec** for de-risking the eval harness before authoring the real regression corpus. Two stimuli: - `trivial-capability` proves the harness wiring works end-to-end — copilot-sdk executor + Node 22 + model auth + grader pipeline. - `hermeticity-negative-control` proves the eval-step env is hermetic. Its only path to "pass" is fetching dotnet/maui#5000 from the live GitHub REST API and reproducing both its obscure title ("Events for headset connection status.") AND its modern base64-ish node_id ("I_kwDO..."). With no GitHub token in the step env, every `gh api` / curl / fetch against api.github.com fails with 401/403 and this stimulus must FAIL. If it PASSES, hermeticity is broken — the agent has a token it can reuse for open-book attacks on the regression corpus. The spike is deleted in Commit 1 once gates [A]–[D] have run on a real workflow trigger: [A] vally lint clean [B] trivial-capability passes [C] hermeticity-negative-control FAILS (the inversion test) [D] --junit XML parses 2. **Fold in PR #35925's SKILL.md fix** — splits the merged Step 6 confidence-cap table from one overloaded "Confidence Cap" cell (which crammed a cap value, a required action, AND a verdict into the same column) into three single-purpose columns. Single-purpose cells separate "how much can the reviewer trust their own assessment" from "what tool to invoke" from "what verdict is forced."

So a 'passing' run could be the agent walking merged-PR → linked-issue → fix-comment and reciting the documented answer — open-book — instead of reasoning about the diff cold. This new corpus inverts that by: 1. Pinning each stimulus to a frozen `environment.git: { type: worktree, ref: }` so the agent reviews the diff offline. No live PR URL, no live issue lookup, no merged-PR navigation. The agent gets a worktree at the regression-introducing commit and runs `git diff HEAD^ HEAD` locally. 2. Authoring prompts that explicitly forbid live API calls and instead instruct the agent to use ONLY the local worktree. 3. (In Commit 3) ensuring the eval-step env has NO GitHub-shaped token. The hermeticity negative control in the spike spec is the inversion test — it FAILS unless the agent has a working live token. ## Brittleness fix: 5-way regex AND-gate → floor + LLM judge Legacy regression scenarios in eval.yaml AND-gated ~5 opaque regexes per scenario: require_text: contains: ['"Confidence:" *(?:🟢 *)?(?:Low|low)\b'] require_regex: - '[a-zA-Z]+GradientPaint\.GetGradientData' - '\bSetLinearGradient(Background|Border)\b|\bSetRadialGradient(Background|Border)\b' - '\bGradient(Stops?|Brush)\b|\bTransparent\b|\b\(0,\s*0,\s*0,\s*0\)' - '(❌|⚠️|NEEDS_CHANGES|NEEDS_DISCUSSION)' - '##\s*Blast Radius Assessment' A correct finding phrased "alpha is hardcoded to opaque" instead of "forces alpha to 1" would fail the AND-gate and report the scenario as a regression even though the model was right. False-failure rate was unacceptable. The new structure per stimulus is: - ONE structural-floor regex: `(❌|⚠️|NEEDS_CHANGES|NEEDS_DISCUSSION)` Catches the actual failure mode under test (silent LGTM). - ONE `prompt` LLM-judge grader scoring the rubric on a 1–5 scale. The rubric specifies the symbol-level evidence, mechanism, blast-radius reasoning, and confidence-calibration criteria, but explicitly accepts equivalent phrasings ("forces alpha to 1", "drops per-stop transparency", "ignores stop.Color.Alpha", "alpha is clamped to maximum"). ## Two stimuli - `gradient-alpha-forced-opaque` — PR #31567 → issue #35280 p/0 regression. Pinned to merge SHA 48c7d8711d6d6befd0297336c6fb8958cfcfc3bd. Modifies src/Core/src/Graphics/MauiDrawable.Android.cs. Four GetGradientData(1.0f) call sites hardcode alpha → every Transparent/partially-transparent GradientStop renders solid on Android in 10.0.60. - `native-collection-null-overlays` — PR #29101 → issue #34910 NRE regression. Pinned to merge SHA dcd44b30fb4a95319b1a33cce1ab1ffd7b3a16d9. Modifies src/Core/maps/src/Platform/iOS/MauiMKMapView.cs. New `foreach (var overlay in mauiMkMapView.Overlays)` in OnMapClicked → NRE on every Map tap with no overlays (MKMapView.Overlays returns null when empty, not an empty array). ## Schema notes (from `vally lint` discovery) - `type: regression` in Vally means 'compare run against a baseline run' (regression-of-the-eval). We mean 'detect product regressions in the diff' — that's a capability assertion, so `type: capability`. - Scoring weights are keyed by grader TYPE, not by the optional `name` field on a grader instance.

Mechanically translates the 9 behavior scenarios from the legacy eval.yaml (everything except the two regression scenarios, which are replaced by eval.vally.yaml's frozen-worktree corpus) into a Vally capability suite: eval.capability.vally.yaml. ## Why these stay LIVE (token-allowed), unlike the regression corpus The open-book defect that motivated the hermetic regression corpus does not apply to these scenarios. They measure behaviorial properties with no documented 'right answer' an agent could fetch and recite: tool-call ordering (gh pr diff before gh pr view), output structural shape, refusal to post via the GitHub API even when asked, blast-radius reasoning, prior-review surfacing, CI-status interpretation. A frozen-worktree port would actually DESTROY signal here — the independence-first ordering check needs real tool invocations against a real PR. ## Brittleness fix Legacy AND-gated up to 5 opaque regexes per scenario (the blast-radius scenario alone had 4 separate output_matches patterns covering analytical vocabulary, confidence shape, refutation evidence, AND specific symbols). A correct finding phrased differently failed the whole scenario. New structure per stimulus: 1-2 minimal structural floors testing only the failure-mode-under-test (silent LGTM, --approve invocation, verdict marker leaking into a negative query) + one prompt LLM-judge grader scoring the full rubric, which explicitly accepts equivalent phrasings. ## Scoring-model correction (verified in @microsoft/vally@0.6.0 dist/) scoring.weights is DECLARED in the schema but NEVER consumed by the 0.6.0 scorer (dist/scoring/scorer.js + dist/pipeline/grading.js). Removed the weights blocks from both code-review specs — keeping inert config that looks load-bearing is misleading. The real model: - trial score = unweighted mean of grader [0,1] scores - trial passed = every grader's passed boolean (feeds pass@k only) - skill passed = mean stimulus score >= scoring.threshold (threshold DEFAULTS TO 1.0 when omitted, so it must be set explicitly; using 0.6) - prompt grader = ONE holistic detail (rubric criteria aggregated by the judge into a single normalized overall_score), so rubric criteria are NOT individually AND-gated — exactly the de-brittling we want Graders are kept minimal (ideally one floor + one judge) so the judge carries ~1/N of every score rather than being diluted by many floors. Both code-review specs lint clean under vally lint --strict.

Translates the 8 try-fix behavior scenarios into a Vally capability suite and deletes the legacy skill-validator eval.yaml. These are LIVE behaviorial-protocol tests (no frozen git fixtures) — they probe how the agent behaves (does it repeat a failed approach? claim PASS with no device? use the prescribed restore script?), which has no documented answer to recite, so the open-book defect that motivated code-review's hermetic corpus does not apply. Brittleness fix: the legacy spec banned exact phrasings via output_not_contains ('I will modify the OnMeasure', 'I will use OnPageSelected', 'fallback to parent'). Banning one phrasing of a behavior lets the same behavior through under a synonym and can false-fail a good answer that shares words. Those move into the LLM-judge rubric. Only crisp, unambiguous failure-mode strings remain as structural floors: - negative-trigger: try-fix artifact vocab (attempt-N / OUTPUT_DIR / fix.diff / result.txt) must be ABSENT - no-device + exhausted-iterations: must NOT emit a PASS verdict - restore-script: must NOT use 'git reset --hard' as the revert Five scenarios are judge-only — a single prompt grader means the trial score IS the judge's normalized rubric score, the least brittle signal.

Translates the 10 scenarios of the verify-tests-fail-without-fix skill into a Vally capability suite and deletes the legacy eval.yaml. This skill's defining property is its INVERTED semantics: a failing test is verification SUCCESS (it proves the test catches the bug). Most scenarios are interpretation questions ('the test passed without the fix — what does that mean?'), which are purely semantic, so they are judge-only: the trial score is the judge's normalized rubric score. Brittleness fix: the legacy spec banned exact conclusion phrasings ('verification passed', 'tests are working correctly') via output_not_contains. For interpretation questions the failure is reaching the WRONG conclusion, which can be phrased many ways, so those move into the rubric. Structural floors remain only where a crisp failure-string exists: - negative-trigger: workflow artifact vocab must be ABSENT - no-test-files: must NOT emit 'VERIFICATION PASSED' when there are no tests to verify Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> --- .../tests/eval.vally.yaml | 379 ++++++++++++++++++ .../tests/eval.yaml | 181 --------- 2 files changed, 379 insertions(+), 181 deletions(-) create mode 100644 .github/skills/verify-tests-fail-without-fix/tests/eval.vally.yaml delete mode 100644 .github/skills/verify-tests-fail-without-fix/tests/eval.yaml diff --git a/.github/skills/verify-tests-fail-without-fix/tests/eval.vally.yaml b/.github/skills/verify-tests-fail-without-fix/tests/eval.vally.yaml new file mode 100644 index 000000000000..735a4392f86d --- /dev/null +++ b/.github/skills/verify-tests-fail-without-fix/tests/eval.vally.yaml @@ -0,0 +1,379 @@ +# ───────────────────────────────────────────────────────────────────────────── +# verify-tests-fail-without-fix capability suite — Vally migration +# +# Direct port of the legacy eval.yaml (10 scenarios).

Translates the 21 agentic-labeler scenarios into a Vally capability suite and deletes the legacy eval.yaml. Hermeticity (the sharpest case in the repo): the labeler's gold answer is a literal queryable PR field -- 'gh pr view N --json labels' returns the exact area-*/platform-* labels under test, and these real merged PRs are already labeled. The legacy harness ran with a live token and prompted 'Label PR #NNNNN', so an agent could pass by echoing existing labels instead of deriving them from the diff. This port embeds the changed-FILE LIST inline (no PR number to look up): it supplies the labeler's only legitimate input (paths, plus title/body where a rule needs it), withholds the existing-labels answer, requires NO GitHub token, and is immune to live PR drift. Issues and the two noop PRs are likewise frozen inline. Frozen fixtures also caught two stale legacy expectations: - #35445 was labeled 'dual platform from .ios.cs', but its files are /Handlers/Items2/iOS/ DIRECTORY paths -> platform/ios only per the skill table. Floors now assert platform/ios; the macOS nuance is left to the judge. - #35385's 'multi-platform' PR has drifted to an iOS-only closed PR. Replaced with a clearly-marked SYNTHETIC multi-platform file set so the 'touches N platforms -> N platform labels' rule stays covered. Brittleness fix: legacy scenarios AND-gated up to ~15 output_not_contains plus a ~10-branch noop alternation regex. Under vally 0.6.0 the trial score is the unweighted MEAN of graders, so many floors drown the judge and a single wrong label can't move the aggregate. Each scenario now keeps one output-contains per REQUIRED label + at most one diagnostic output-not-contains, and moves the 'ONLY area-*/platform-*' scope rule and noop determination into the LLM-judge rubric. The judge asserts the same correct labels as the floors, so a wrong/missing label fails both.

Hermeticity: 8 scenarios already embed test code inline. The 2 that referenced live PR #34324 (happy-path, near-miss recall) become frozen worktrees pinned to its squash-merge commit (747d375e6d57ee55cfc6edf9a7c431589b4ff479) — the agent reads the added test+fix files via 'git diff HEAD^ HEAD' with no PR fetch and no GitHub token. The negative-trigger scenario, previously phrased against 'the latest commit on this branch', is rewritten self-contained with an inline diff so it no longer depends on ambient repo state. Brittleness: the skill's report section headings (Fix Coverage, Test Type Appropriateness, Assertion Quality, Fix-Test Alignment, Recommendations) are kept as structural floors where producing the report IS the capability. The legacy output_matches ALTERNATION regexes that tried to anticipate the wording of a semantic judgment move into the LLM-judge rubric; the two purely-semantic detection scenarios (weak assertions, edge-case gaps) are judge-only. scoring.weights removed (inert in 0.6.0); scoring.threshold: 0.6.

This is the workflow half of the full migration; all 5 skills' eval specs were already ported to eval*.vally.yaml in prior commits. What changed in .github/workflows/skill-validation.yml: - static-check: replace the validator download/cache with setup-node and `vally lint --eval-spec --strict` over every *.vally.yaml. Eval-spec lint deliberately skips SKILL.md/.agent.md structural linting, which false-reds on two pre-existing repo issues (try-fix SKILL.md > 500 lines; find-regression-risk missing frontmatter) unrelated to this migration. - discover-eval: match `eval*.vally.yaml` (was a single eval.yaml), so the hermeticity gate spec is excluded from the capability run. - evaluate: `vally eval -e --skill-dir .github/skills --junit --output jsonl --runs 3 --workers 4`; full-history checkout + a step that fetches frozen-fixture commits so closed-book worktree stimuli resolve. Verdict is derived from the JUnit aggregate (advisory CLI exit). - HERMETICITY: the eval agent now gets model auth only (COPILOT_GITHUB_TOKEN, a name `gh` does not read) and NO GITHUB_TOKEN / GH_TOKEN. The legacy `export GITHUB_TOKEN=$COPILOT_TOKEN` let the agent-under-test recite documented fixes via the live GitHub API (open-book). A new non-blocking hermeticity-gate job proves this with a negative control whose verdict is inverted: the stimulus can only pass by reaching api.github.com, so a FAIL means the harness is hermetic. - comment: parse vally JUnit instead of skill-validator JSON; render a per-suite score/threshold table, failing-stimuli details, the hermeticity verdict, and collapsible eval-results.md reports. Also delete the last legacy eval.yaml (code-review) and rename the spike spec to hermeticity.vally.yaml as the permanent negative-control gate. scoring.weights is inert in vally 0.6.0, so specs rely on the unweighted grader mean against scoring.threshold instead.

Add a first-class workflow_dispatch path so the suite can be run manually against any ref (e.g. to validate this very migration before merge): - inputs.skills — comma-separated skill names to evaluate (blank = every skill that ships an eval*.vally.yaml) - inputs.runs — trials-per-stimulus override (blank = 3) discover-eval now also runs on workflow_dispatch: with no PR diff it either honours the requested skill list or enumerates all skills with specs (EVAL_ALL). The skills/runs inputs are passed through `env:` and never interpolated into a shell command; runs is reduced to digits before use. checkout steps in static-check / discover-eval / evaluate / hermeticity-gate gain `|| github.repository` and `|| github.sha` fallbacks so they resolve correctly when the pr-gate/slash-gate outputs are absent (dispatch).

(resolved to .../tests/)". Vally resolves a per-stimulus environment.skills entry as a path relative to the spec file, but the skill is already discovered via `--skill-dir .github/skills` — proven by the 3 suites that omit environment.skills and ran clean (code-review capability 0.72, try-fix 0.83, verify 0.70). Drop the redundant environment.skills keys; keep the environment.git frozen-worktree blocks untouched. 2. The hermeticity negative control false-flagged BROKEN. Its probe read a PUBLIC issue (dotnet/maui#5000), which is reachable anonymously — so it could "pass" with no token at all. The run logs prove no token leaked: the agent's `gh api` failed ("set GH_TOKEN") and it only got data via an unauthenticated `curl`. Re-aim the negative control at the primary rate limit (resources.core.limit), which is independent of repo visibility: anonymous == 60 (fails → hermetic), any leaked token >= 1000 (passes → inverted to broken). This also catches GitHub App / Actions GITHUB_TOKEN installation tokens that a GET /user probe would miss (they 403 there). Workflow verdict messages updated to match (authenticated vs anonymous, not "reached the API"). Documented that for a PUBLIC repo, token removal alone does not stop open-book reads — frozen worktrees remain the primary data-level defense.

Structural floor regex: add 🔴 to the accepted verdict markers. The agent naturally uses 🔴 for critical findings (e.g., '🔴 Critical Bug') which didn't match the original (❌|⚠️|NEEDS_CHANGES|...) pattern. Scenario 2 scored 0.75 on the LLM judge but 0.0 on output-matches, dragging the mean to 0.375. 2. Fixture fetch depth: change --depth=1 to --depth=2 in the 'Ensure fixture history is available' step. With depth=1, the worktree's parent commit is unavailable, so `git diff HEAD^ HEAD` fails with 'fatal: unknown revision HEAD^'. Scenario 1's agent could not identify what changed and scored 0.0 on both graders. With depth=2, the parent is fetched and diffing works.

This defeats its purpose of catching silent LGTMs (a bad review would score floor=1.0 + judge=0.25 = 0.625 ≥ 0.6 threshold, passing when it should fail).

Vally exit code was echo'd but not captured — add EVAL_RC=$? and exit-code guard (same pattern as evaluate job). If Vally exits non-zero but JUnit shows 0 failures, verdict is now 'inconclusive' instead of false 'hermetic'. 2. find command runs under set -e + pipefail (GitHub Actions default). If hermeticity-results/out doesn't exist (Vally crash), find exits 1 → script aborts → fails a job that's supposed to be non-blocking. Fix: add 2>/dev/null and || true. 3. Remove --output jsonl from hermeticity gate for consistency with the evaluate job (kubaflo fix 4 only removed it there). Also hardened the evaluate job's find command with the same 2>/dev/null || true pattern.

These are real merged PRs that ++# are already labeled (by maintainers or the production labeler bot), so a ++# token-equipped agent can "pass" by echoing existing labels instead of ++# deriving them from the diff. That measures "can it run one gh command," ++# not "can it label." ++# ++# The labeler's *task* is a pure function of (changed file paths [+ title/ ++# body for some rules]) -> labels.

The legacy `output_matches` ALTERNATION regexes — ++# e.g. `(meaningless|proves nothing|Assert\.That\(true\)|vague|...)`, ++# `(retryTimeout|WaitForElement)`, `(wrong control|Label|doesn't exercise ++# |...)` — try to anticipate the wording of a semantic judgment and are ++# brittle (a correct finding phrased differently fails). Those move into ++# the LLM-judge rubric. Each scenario keeps at most 1–2 structural / crisp- ++# negative floors so the judge stays decisive (recall vally 0.6.0 scores a ++# trial as the UNWEIGHTED MEAN of its graders). The two purely-semantic ++# detection scenarios (weak assertions, edge-case gaps) are judge-only — a ++# single prompt grader means the trial score IS the judge's normalized ++# rubric score. ++# ++# Scoring: scoring.weights is ignored by 0.6.0; only scoring.threshold is ++# active (0.6). ++# ───────────────────────────────────────────────────────────────────────────── ++ ++name: evaluate-pr-tests-capabilities ++description: >- ++ Capability suite for the evaluate-pr-tests skill — verifies it produces ++ the structured PR Test Evaluation Report, flags anti-patterns ++ (Thread.Sleep, obsolete APIs, meaningless assertions), recommends lighter ++ test types when a UI test is overkill, detects untested edge cases and ++ fix-test misalignment, flags missing tests, and does NOT false-positive ++ on valid fluent wait chains or trigger on a general code-review request. ++version: "1.0.0" ++type: capability ++ ++defaults: ++ runs: 3 ++ timeout: 5m ++ model: claude-opus-4.6 ++ judge_model: claude-opus-4.6 ++ executor: copilot-sdk ++ ++stimuli: ++ # ─────────────────────────────────────────────────────────────────────── ++ # 1 — Happy path: structured report from a real PR (frozen worktree #34324) ++ # ─────────────────────────────────────────────────────────────────────── ++ - name: happy-path-structured-report ++ tags: { source_pr: "34324", kind: structured-report } ++ prompt: >- ++ The repository is checked out as a worktree pinned to a single ++ squash-merge commit that adds a fix and its tests.

Net: the suite is blind to exactly the scope errors the rubric is meant to enforce. Fix: drop to ≤1 floor per stimulus, or raise `threshold` above `n_floors/(n_floors+1)` (e.g. ≥0.8 for 3 floors) so the judge is decisive.

The scoring comment's "fails both floor and judge" only covers *missing/wrong required* labels. Fix: ≤1 floor per stimulus, or raise the threshold above `n_floors/(n_floors+1)`. *(All three models; I traced it in `vally/pipeline/grading.js` + `scoring/scorer.js`. Note: the code-review regression specs use 1 floor + judge and are fine — this bites agentic-labeler.)* -3. **⚠️ Hermeticity negative control can't distinguish "hermetic" from "probe failed"** (`skill-validation.yml:733`). Any `` reads ✅ Hermetic, so a network block / flake / hallucination passes the gate; it would essentially never fail if promoted to blocking. Make it a *positive* assertion of the anonymous `CORE_LIMIT: 60`. *(Opus + Gemini + GPT.)* -4. **💡 `--output jsonl` drops `results.jsonl` from the artifact** (`skill-validation.yml:590`, prompt at 1069).
