## Summary of the Pull Request Replaces the retired GitHub Models-based automatic issue triage and deduplication flows with the GitHub Agentic Workflow proven in the `niels9001/powertoys-ai-triage-sandbox`. This PR also: - aligns `Needs-Author-Feedback` closure to 7 days for issues and PRs; - removes the automatic GitHub Models issue/PR labeler; - removes the automatic GitHub Models new-issue deduplicator; - removes the Azure Pipelines XAML Styler verification step while retaining the local styling script. This is a draft because production rollout still requires the appropriate privacy and Responsible AI reviews. ## Issue triage rules ### Triggers and refresh behavior - Runs when an issue is opened, edited, or reopened. - Runs when the issue author attaches a `PowerToysReport_*.zip` in a comment. - Maintainers can force regeneration with `/triage refresh`. - Ignores unrelated comments, unchanged issue edits, PR comments, and bot-initiated reopens. - Uses per-issue concurrency so a newer run supersedes an older run. - Maintains one canonical triage comment instead of adding repeated bot comments. ### Comment format - Separates **For the issue author** from **For the PowerToys team**. - Mentions the author once and lists each requested action as a bullet. - Distinguishes blocking **Needed** actions from non-blocking **Recommended** actions. - Shows the product, issue kind, reported PowerToys version, concise summary, diagnostic findings, possible duplicates, and collapsed investigation checks. - Ends with a short disclosure that triage is AI-assisted and maintainers make final decisions. ### Classification and labels - Detects PowerToys bug-template issues deterministically. - Reads the selected product area and adds a matching primary `Product-*` label. - Handles production aliases such as FancyZones Editor and File Explorer preview/thumbnail areas. - Product labeling is additive: existing product and maintainer labels are never removed. - Normalizes the reported PowerToys version and adds a matching version label when one exists. - Applies `Needs-Author-Feedback` only when blocking information or an English translation is required. - Removes `Needs-Author-Feedback` when the issue becomes actionable. ### PowerToys version rule - Compares the reported version with the latest stable PowerToys GitHub release. - Older versions receive a recommended update-and-retest action. - Current versions, newer preview/dev versions, missing versions, and release lookup failures are not flagged as outdated. - Updating is advisory and does not block triage by itself. ### Reproduction rule - Concrete actions plus an observed result are sufficient. - Concise steps can use the separate Actual Behavior section as the observed result. - Passive or intermittent failures are sufficient when the timing/trigger and observed failure are clear. - Vague statements without an actionable scenario remain insufficient. - Clearly non-English steps are not treated as missing; reproduction is reassessed after the author translates the issue. ### Language rule - Classifies author-written prose as English, non-English, or uncertain. - Ignores template headings, code, logs, filenames, URLs, hidden comments, and quoted text. - Clearly non-English issues ask the author to translate the title and description to English. - Short, mixed, code-heavy, or uncertain text is not flagged. ### Diagnostic report rule - A report is **required** for diagnostic-heavy failures: crashes, hangs, startup/load failures, installation/update failures, performance failures, and service/driver/shell-integration failures. - A report is **optional** for clear reproducible UI/visual defects. - A report is **recommended**, but not blocking, for other actionable bugs. - Missing or rejected reports block only when the deterministic requirement is `REQUIRED`. ### Diagnostic report privacy and safety - Accepts only PowerToys report attachment URLs matching the expected pattern. - Enforces archive size, decompressed size, file-count, per-file, path traversal, and encryption limits. - Selects only bounded relevant metadata and product-log evidence. - Redacts email addresses, IP addresses, user paths, URLs, GUIDs, SIDs, identity fields, tokens, secrets, and passwords. - Sends only the sanitized evidence to Copilot. - Never sends the raw ZIP or extracted files to Copilot, logs, artifacts, or repository storage. - Deletes the temporary archive after processing. ### Duplicate rule - Searches only older issues using focused product, title/body, and exact technical-signal queries. - Ranks candidates deterministically before Copilot runs. - Copilot judges only the supplied candidates and returns at most five high-confidence matches. - Similar product area alone is not enough; the underlying request or failure must match. - The model never closes an issue directly. - The workflow submits the strongest match as a native GitHub duplicate-close suggestion. - **When a maintainer accepts the suggestion, GitHub automatically closes the issue as a duplicate and links it to the selected canonical issue.** - Declining the suggestion leaves the issue open. - A defensive safeguard reopens the issue and fails the run if GitHub applies the close without holding it for review. ### AI cost and permission controls - Uses the `small` model alias. - Maximum 5 turns and 10 AI credits per run. - Maximum 300 AI credits per day. - Maximum 5 runs per user per 60-minute window. - Content hashing skips unchanged work before inference. - The agent receives only `contents: read`, `issues: read`, and `copilot-requests: write`. - A separate validated safe-output job receives `issues: write`. ## Seven-day author-feedback lifecycle The existing Microsoft GitHub Policy Service configuration remains responsible for stale closure: - Open issues with `Needs-Author-Feedback` and no activity for 7 days are closed with an explanatory comment. - Open PRs with `Needs-Author-Feedback` and no activity for 7 days are closed with an explanatory comment. - An author comment removes `Needs-Author-Feedback` and returns the issue/PR to team triage. - An author push removes `Needs-Author-Feedback` from a PR. - Manually removing the label immediately makes the issue or PR ineligible for scheduled closure. ## Deprecated automation - Deletes `.github/workflows/automatic-issue-deduplication.yml`. - Deletes `.github/workflows/auto-labeler.yml`. - Automatic PR product labeling from the old Models workflow is intentionally not replaced in this PR; a production PR ownership/path map should be agreed separately. - Keeps the manual batch deduplication workflow unchanged. - Removes the passive XAML Styler verification step from `.pipelines/v2/templates/job-build-project.yml`. - Keeps `.pipelines/applyXamlStyling.ps1` available for local developer use. ## Validation Steps Performed - Compiled `.github/workflows/issue-triage.md` with `gh aw compile`. - Ran 32 focused Python tests for issue parsing, duplicate retrieval, version checks, reproduction rules, language signals, archive validation, report selection, redaction, and output privacy. - Parsed the changed workflow and resource-management YAML. - Verified the required production labels exist. - Tested the workflow against the latest 20 PowerToys issues in the sandbox; all 20 produced one canonical comment. - Verified live variants for outdated versions, intermittent/passive reproduction, non-English issues, rejected and analyzed reports, optional UI reports, and title-only issues. ## PR Checklist - [ ] **Communication:** Discussed with core contributors. - [x] **Tests:** Added/updated and all focused tests pass. - [ ] **Privacy / Responsible AI:** Complete required production reviews before enabling. - [x] **Localization:** No product UI strings are added. - [x] **Dev docs:** Updated repository automation documentation. - [x] **New binaries:** None. --------- Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> Copilot-Session: 18a9b8ad-fd7e-4b9d-a06c-5e350bcde9d7 Copilot-Session: fd512b9b-db6f-4004-a65b-aa49404d568d Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> Copilot-Session: 7b3fb20d-6e9d-4fef-a5cd-f8921d28c220
