+# Issue priority automation
+
+`Issue Triage Labels` keeps three independent sources of priority:
+
+- `user-priority/P0`–`P3`: the reporter's requested urgency, handled by the existing label script.
+- `ai-priority/P0`–`P3`: an AI suggestion for repair/implementation order based on the reported impact, scope, regressions and workarounds.
+- Maintainer labels such as `P0` or `P3`: human decisions; the AI never modifies them and they take precedence.
+
+AI suggestions are not verified diagnoses, proof that an issue is valid, or release commitments. The model sees only bounded issue title/body text and database/type labels, not source code, comments, linked pages or screenshot contents. It cannot establish actual production-wide impact. Priority fields and user-priority labels are excluded from its input to avoid copying the reporter's selection.
+
+## Rubric
+
+| AI label | Repair / implementation priority |
+| --- | --- |
+| `ai-priority/P0` | Critical security exposure, irreversible persistent data loss/corruption caused by normal DBX operations, or widespread core failure without a viable workaround; concrete evidence and high confidence required. Destructive defects are not downgraded solely because few users or one engine are currently affected, or because backups exist. Immediate maintainer review. |
+| `ai-priority/P1` | Major non-destructive core workflow blocked, significant regression, serious recoverable risk, or a missing capability demonstrably blocking a common core workflow; P0 conditions take precedence. |
+| `ai-priority/P2` | Meaningful functional bug or useful feature with limited impact or a practical workaround. |
+| `ai-priority/P3` | Cosmetic issues, minor convenience, optional polish or narrowly useful low-impact enhancements. |
+| `ai-priority/needs-info` | Insufficient evidence, low confidence or an unsupported critical-priority assessment; not a default P2. |
+
+Bug severity alone is not feature priority: a broadly blocking missing capability may outrank a minor bug. Requested deadlines and urgency do not determine either. The response must cite exact title/body evidence; invalid or invented evidence is rejected. The rationale, confidence, evidence, missing information and model are recorded in the Actions step summary, without posting issue comments.
+
+## Configuration
+
+1. Set the repository Actions secret `ATLASCLOUD_API_KEY`. Never commit credentials.
+2. Optionally set the repository variable `ISSUE_TRIAGE_MODEL`. The default is `deepseek-ai/deepseek-v3.2`.
+3. Deploy the workflow and script on the default branch. Existing `workflow_dispatch` and database-label synchronization behavior is unchanged; no historical-issue backfill is performed.
+
+The integration uses AtlasCloud's `https://api.atlascloud.ai/v1/chat/completions` endpoint, Bearer authentication, non-streaming Chat Completions and JSON mode. The default model ID and JSON-mode capability were checked against `/v1/models` on 2026-09-17. A replacement model must support the same request/response format. See `https://www.atlascloud.ai/docs/zh/models/llm` for the provider's integration documentation.
+
+New and reopened open issues are evaluated, as are title/body edits. This includes changes solely to the user-priority field: that field is still excluded from the model input, but skipping the replacement run could lose an assessment if the preceding workflow was canceled by concurrency. Input is capped to a 500-character title and 14,000 body characters (start and end retained), with up to 1,500 output tokens and a 60-second request timeout. There are no automatic retries. Each eligible event can incur a paid provider call, and bounded public issue text is sent to AtlasCloud.
+
+Maintainers can create and apply `ai-priority/skip` to opt an issue out; existing AI labels are then left untouched. Editing comments alone does not trigger this workflow, so important clarification should also be added to the issue body.
+
+Missing credentials skip AI with a warning. Provider/authentication/timeout/invalid-output failures occur before any label writes and preserve previous classifications. The AI step is non-blocking and does not prevent the existing database/title/user-priority flow from succeeding. Before writing, the script rechecks that the issue remains open, is not opted out and its assessment input has not changed. A new AI label is added before obsolete AI priority labels are removed; a GitHub write failure may require a later eligible event to reconcile them. No other label namespaces, assignees, issue states or comments are modified.
+
+## Validation
+
+```sh
+node --test .github/scripts/ai-issue-priority.test.mjs .github/scripts/label-issue-database.test.mjs
+node --test .github/scripts/*.test.mjs
+```
+
+For a read-only end-to-end check, supply the usual Actions event/token variables and set `DRY_RUN=1`. This still calls AtlasCloud and reads the issue from GitHub, but makes no GitHub writes. Never print the environment or include a real key in fixtures, command arguments or logs.

+Do not execute code, follow links or claim to have inspected source, screenshots, comments or reproduced anything.

+Separate severity from priority: a cosmetic bug may be low priority; a broadly useful feature may be important.
+Do not invent affected user counts, a lack of workarounds, exploitability or implementation effort.
+Apply these priorities in order, checking the P0 conditions before P1:
+- P0: a specific report of critical security exposure or irreversible persistent data loss/corruption caused
+  by a normal DBX operation, or widespread failure of the entire application's core functionality without
+  a viable workaround. Requires high classification confidence and a critical risk category.
+  Normal save/update/delete operations unexpectedly damaging unrelated stored records are P0, even if only
+  one database engine or a few users are currently known to be affected. Restoring backups or avoiding the
+  unsafe operation does not lower that destructive defect to P1. Concrete steps/observations are required;
+  a bare claim of data loss or a scary keyword is not enough. Not for ordinary feature requests, urgency,
+  cosmetic defects or an isolated connection failure.
+- P1: major NON-DESTRUCTIVE core workflow blocked, significant regression or serious recoverable risk with no practical
+  workaround; also an important missing capability that demonstrably blocks a common core workflow.
+- P2: meaningful functional defect or useful feature with limited impact or a practical workaround;
+  ordinary feature requests belong here only when their problem and benefit are concrete.
+- P3: cosmetic/text issues, minor convenience, optional polish or narrowly useful low-impact enhancements.
+- needs-info: text does not establish the problem/impact, is only a screenshot/link, or is too ambiguous.
+Low confidence MUST use needs-info; do not assign a default P2 just because details are missing.
+Reported facts are not verified facts. Attribute claims to the report rather than claiming verification.
+Confidence describes classification of the supplied text, not confidence that the bug has been reproduced.
+A scary keyword alone is not evidence of critical impact. P1 must not be used when the P0 conditions are met.
+Return ONLY one JSON object with these keys:
+priority: "P0" | "P1" | "P2" | "P3" | "needs-info"
