## ✅ Resolved Since Yesterday (4)

> These were in yesterday's report but are no longer detected in the last 24h.

### ~~Evaluation failure rate across all branches exceeds 30% (critical)~~
Re-sampled with the current 24h window (7 runs across all branches/events): 1 failure / 3 completed success-or-failure runs = ~25% failure rate — now below the 30% critical threshold, but still above 15%, so this demotes to the pre-existing `pipeline:evaluation:failure-rate:warning` finding rather than disappearing entirely (see Existing Findings).

### ~~Evaluation workflow failed on main: vally (dotnet-ai--claude-haiku-4.5) — Run vally evaluations~~
No recurrence of this specific shard/model failure in the last 24h — different shards (dotnet-blazor, dotnet-data, dotnet-maui, dotnet-diag) failed instead in today's scheduled run.

### ~~skill-coverage workflow run cancelled on main (comment job)~~
No cancelled/timed-out runs detected on `main` in the last 24h window.

### ~~Orphan plugin: dotnet-test-migration not in marketplace.json~~
`plugins/dotnet-test-migration` is now listed in `.github/plugin/marketplace.json` (`./plugins/dotnet-test-migration`) — no longer orphaned.

> Note: `pipeline:evaluation:vally-(dotnet-maui--claude-haiku-4.5)...` and `dotnet-diag--mai-code-1-flash-picker` from two runs ago were already dropped in the prior run and remain absent.

## 📌 Existing Findings (4)

> These have been present since before today. Sorted by age.

🟡 Warning — Orphan plugin: dotnet-experimental not in marketplace.json · first seen 2026-05-14 · 68 occurrences

**Fingerprint:** `infra:orphan-plugin:dotnet-experimental`
**Category:** Infra · **Severity:** 🟡 Warning

The plugin directory `plugins/dotnet-experimental/` has a valid `plugin.json` (skills field resolves correctly) but is still **not listed** in `.github/plugin/marketplace.json`. ~109 days outstanding.

**Suggested action:** Either add `dotnet-experimental` to `marketplace.json` if ready for consumers, or remove the plugin directory if no longer needed.

🟡 Warning — Validate PAT Pool workflow failed: Build summary step · first seen 2026-08-05 · 9 occurrences

**Fingerprint:** `pipeline:validate-pat-pool:validate-copilot-pat-pool:build-summary:failure`
**Category:** Pipeline · **Severity:** 🟡 Warning

The `validate-pat-pool.yml` workflow failed again at the Build summary step ([Run #85](https://github.com/dotnet/skills/actions/runs/33351214606), all 10 individual PAT validation steps succeeded, only the summary step failed).

**Suggested action:** This recurring failure has now persisted for 9+ occurrences since 2026-08-05 — file a dedicated tracking issue given the sustained recurrence; the summary-generation logic itself likely has a bug independent of the PATs it validates.

🟡 Warning — Evaluation failure rate across all branches exceeds 15% · first seen 2026-08-27 · 3 occurrences

**Fingerprint:** `pipeline:evaluation:failure-rate:warning`
**Category:** Pipeline · **Severity:** 🟡 Warning

24h window (7 total runs, all branches/events): 1 failure, 3 successes, 2 skipped, 1 action_required. Failure rate = 1/(1+3) = 25%, above the 15% warning threshold (demoted from critical — see Resolved section). Event breakdown: 1 schedule failure (the same run driving the 4 new vally-shard findings above), 0 pull_request/workflow_dispatch failures.

**Suggested action:** Continue monitoring; if failure rate persists above 15% next run, treat as trending upward.

🔴 Critical — Eval avg run duration exceeds 55 min (critical threshold) · first seen 2026-08-28 · 2 occurrences

**Fingerprint:** `resource:eval-duration:critical`
**Category:** Resource · **Severity:** 🔴 Critical

Sampled the last 30 `evaluation.yml` runs on `main`; for the 30 completed (success/failure) runs within the last 14 days, average duration is **~76.5 min**, above the 55-min critical threshold (60-min workflow timeout).

**Suggested action:** Investigate whether the evaluation matrix has grown or a subset of shards are consistently slow; consider increasing the timeout or splitting the matrix to reduce per-run duration. This likely correlates with the recurring scheduled-run failures above.

## 📊 Trends (7-day)

| Metric | Today | 7d Avg | Δ | Trend |
|--------|-------|--------|---|-------|
| Eval duration (min, main, n=30, 14d) | ~76.5 | ~93 (prior estimates) | -16.5 | ✅ |
| Eval success rate (main, n=30 completed) | 72% (13/18 strict) | ~76% | -4pp | ⚠️ |
| Eval success rate (all branches, 24h, n=3 completed) | 75% (3/4) — wait, see note | 50% (prior day) | ~ | ✅ |
| Eval scheduled cancellation rate (24h, main) | 0% (0/1) | 0% | 0 | ➡️ |

> **Correlation:** All 4 new critical vally-shard failures (`dotnet-blazor`, `dotnet-data`, `dotnet-maui`, `dotnet-diag`) trace back to the **same single scheduled run** (#33298539883), consistent with last run's pattern where multiple shards failed together in one scheduled run. Combined with the still-critical eval-duration finding (~76.5 min avg) and the still-active `evaluation:failure-rate:warning`, this continues to suggest the eval pipeline occasionally fails broadly within a single scheduled run — worth checking whether resource contention, a shared dependency, or a transient infra issue around scheduled-run time is the common cause.
>
> **Recommendations:**
> 1. Investigate the single failed scheduled run (#33298539883 / run #8011) holistically — 4 shards failed together at "Run vally evaluations", suggesting a shared cause rather than per-shard flakiness.
> 2. The eval-duration critical finding persists at 2 occurrences (~76.5 min avg) — prioritize investigating matrix growth or slow shards; this may also explain schedule-driven shard failures if runs are timing out under load.
> 3. File a standalone tracking issue for the `validate-pat-pool` Build-summary failure, now at 9 occurrences since 2026-08-05.
> 4. Resolve the remaining `dotnet-experimental` orphan-plugin gap in marketplace.json (109+ days outstanding) — `dotnet-test-migration` was resolved this run, showing the pattern is fixable.
> 5. Investigate the new `Issue Triage` workflow failure (Execute GitHub Copilot CLI step) — first occurrence, could indicate an emerging Copilot CLI/agent issue worth tracking if it recurs.

> ⚠️ Skipped Pages deployment check (I5): no Pages-related MCP tool/endpoint available this run — check appears not applicable or not reachable with available tooling.
> ⚠️ Skipped relaxed-skill-validation (I3): no `validate-skills.yml` file exists in `.github/workflows/`; closest analog `skill-validator.yml` does not contain `fail-on-warning: false` — no finding raised.
> ⚠️ Skipped verdict-warn-only (I4): `evaluation.yml` does not contain `--verdict-warn-only` — no finding raised.
> ⚠️ I6 (unpinned third-party actions): scanned all workflow YAML files for non-`actions/*` references — found `github/codeql-action` and `super-linter/super-linter`, both already pinned to full commit SHAs. No unpinned-action findings.
> ⚠️ I7 (orphan skills): all 15 plugin directories under `plugins/*/` have a `plugin.json` at their root resolving a `./skills/` path containing the discovered skill directories; no orphan skills detected.
> ⚠️ U3 (cost trend) and full 7-day workflow-failure-rate/compute-hours trends not computed this run due to time budget — carried over as "not computed" from prior runs.

## 📌 Existing Findings (3)

> These have been present since before today. Sorted by age.

🟡 Orphan plugin: dotnet-experimental not in marketplace.json · first seen 2026-05-14 · 69 occurrences

**Fingerprint:** `infra:orphan-plugin:dotnet-experimental`

`plugins/dotnet-experimental/plugin.json` is valid and points to `./skills/`, but no marketplace entry targets that directory. [Review marketplace configuration](https://github.com/dotnet/skills/blob/main/.github/plugin/marketplace.json).

**Suggested action:** Register the plugin when ready for consumers, or remove it if it is intentionally retired.

🟡 Validate PAT Pool workflow failed: Build summary step · first seen 2026-08-05 · 10 occurrences

**Fingerprint:** `pipeline:validate-pat-pool:validate-copilot-pat-pool:build-summary:failure`

All ten PAT checks succeeded, but **Build summary** failed again in [run 97](https://github.com/dotnet/skills/actions/runs/34668024583).

**Suggested action:** Fix the recurring summary-generation bug independently of token validity.

🔴 Eval avg run duration exceeds 55 min · first seen 2026-08-28 · 3 occurrences

**Fingerprint:** `resource:eval-duration:critical`

The 25 completed main-branch evaluation runs sampled over 14 days averaged **98.8 minutes**, well above the 55-minute critical threshold. [Review evaluation runs](https://github.com/dotnet/skills/actions/workflows/evaluation.yml).

**Suggested action:** Split or reduce the evaluation matrix and address queue/runtime bottlenecks.

## 📊 Trends (7-day)

| Metric | Today | 7d Avg | Δ | Trend |
|--------|-------|--------|---|-------|
| Eval duration (min) | 98.8 | 76.5 prior sample | +22.3 | ⚠️ |
| Eval success rate (main) | 0% (0/4 completed) | unavailable | — | ⚠️ |
| Eval success rate (all branches) | 47.6% (10/21 completed) | unavailable | — | ⚠️ |
| Eval scheduled cancellation rate | 0% (0/1) | 0% prior | 0pp | ➡️ |
| Workflow failure rate (7d) | unavailable | unavailable | — | ➡️ |
| Compute hours/day | unavailable | unavailable | — | ➡️ |

> **Correlation:** The critical failure-rate spike, 12 scheduled shard failures, and three repeated csharp-refactoring failures all share the same token-selection step. The 98.8-minute evaluation average compounds this risk but scheduled cancellation remained 0%.
>
> **Recommendations:**
> 1. Restore and validate Copilot PAT pool capacity before retrying evaluation runs.
> 2. Investigate why session-data publication fails after token-selection failures.
> 3. Fix the PAT validation summary step, now recurring for 10 health checks.
> 4. Resolve the long-standing `dotnet-experimental` marketplace registration gap.

> ⚠️ Skipped Pages deployment check: the available GitHub read tools expose no Pages deployment endpoint.
> ⚠️ Skipped exact 7-day workflow-failure and repository-wide compute-hour trends: the bounded Actions result set did not cover the complete windows.

# 🏥 Daily Health Check — 2026-09-13

**Status:** 🔴 12 critical · 🟡 2 warnings · 🔵 0 info
**Since yesterday:** 🆕 10 new · ✅ 16 resolved · 📌 4 unchanged

> 📌 **Maintainer action needed:** please pin this issue as the canonical health dashboard and unpin/close any stale duplicate.

> **Executive summary:** Ten new evaluation job failures appeared in one scheduled run; the aggregate evaluation failure rate and duration remain critical, while 16 prior run-specific failures resolved.

> ⚠️ Skipped Pages deployment health: the available GitHub read interface does not expose Pages deployment status. Complete all-workflow compute and 7-day failure-rate metrics were also unavailable because the run listing was capped before the requested time window.

## 📌 Existing Findings (4)

> These have been present since before today. Sorted by age.

🔴 Evaluation failure rate across all branches exceeds 30% — first seen 2026-09-12 · 2 occurrences

The last 24 hours contained 3 evaluation events: 1 failure, 0 successes, 0 cancellations, and 2 skipped review events. Excluding cancellations and skipped runs, the failure rate is **100%**. The sole completed run was the [scheduled run 9100](https://github.com/dotnet/skills/actions/runs/34680113000).

**Action:** Resolve the common token-pool failure, then rerun evaluation to restore a meaningful successful sample.

🔴 Eval avg run duration exceeds 55 min — first seen 2026-08-28 · 4 occurrences

The latest 30 completed main-branch evaluation runs averaged **93.8 minutes**; the latest scheduled run lasted **363.1 minutes**.

**Action:** Separate queue delay from execution time and reduce long-running scheduled matrices or adjust scheduling/concurrency.

🟡 Validate PAT Pool failed at Build summary — first seen 2026-08-05 · 11 occurrences

[Run 98](https://github.com/dotnet/skills/actions/runs/34733390345/job/103660277108) failed at `Build summary` after all ten PAT validation steps completed successfully.

**Action:** Fix summary logic so a successful pool validation does not fail the workflow.

🟡 Orphan plugin: dotnet-experimental — first seen 2026-05-14 · 70 occurrences

[`plugins/dotnet-experimental`](https://github.com/dotnet/skills/tree/main/plugins/dotnet-experimental) contains a valid `plugin.json` and registered skills, but no marketplace entry points to the directory.

**Action:** Add `./plugins/dotnet-experimental` to `.github/plugin/marketplace.json`, or remove the plugin if it is intentionally undiscoverable.

## 📊 Trends (7-day)

| Metric | Today | 7d Avg | Δ | Trend |
|--------|-------|--------|---|-------|
| Eval duration (min) | 363.1 | 93.8 | +269.3 | ↗️ Increasing (watch) |
| Eval success rate (main) | 0% | 8.0% | -8.0 pp | ⚠️ Degrading |
| Eval success rate (all branches) | 0% | 43.8% sampled | -43.8 pp | ⚠️ Degrading |
| Eval scheduled cancellation rate | 0% | 0% observed | 0 pp | ➡️ Stable |
| Workflow failure rate (7d) | unavailable | unavailable | — | ➡️ Incomplete source window |
| Compute hours/day | unavailable | unavailable | — | ➡️ Incomplete source window |

**Recommendations:**
1. Restore MAI token-pool capacity or selection behavior first; it accounts for 8 of 10 new job failures.
2. Investigate the two independent Claude Haiku Vally failures after the shared token issue is contained.
3. Correct the recurring PAT summary failure and either register or retire `dotnet-experimental`.

# 🏥 Daily Health Check — 2026-09-14

**Status:** 🔴 3 critical · 🟡 4 warnings · 🔵 0 info
**Since yesterday:** 🆕 4 new · ✅ 11 resolved · 📌 3 unchanged

> 📌 **Maintainer action needed:** please pin this issue as the canonical health dashboard and unpin/close any stale duplicate.

**Executive summary:** Four new pipeline failures were detected. The all-branch evaluation failure rate remains critical at 64.9%, while the prior evaluation-duration threshold breach cleared.

**Priority:** Investigate the two failed Claude Opus evaluation jobs first, then the Copilot CLI failures in dashboard grooming and issue triage. The 23 evaluation push failures suggest a workflow/configuration issue distinct from the two scheduled Vally job failures.

> ⚠️ Skipped Pages deployment checks: the available GitHub read tools do not expose Pages deployment status.
