-            Output rules:
-            - Start with a 1-2 sentence summary.
-            - Write a single concise PR comment.
-            - No emojis. No code snippets. No fenced blocks.
-            - Short inline code identifiers allowed, but no snippets or fenced blocks.
-            - Reference evidence with file paths and line ranges (e.g., path/to/file.ts:120-138).
-            - Keep the entire comment under ~300 words.

-            Report:
-            - Must-fix issues (blocking) — brief why and a one-line action each.
-            - Nice-to-have improvements (optional) — brief why and a one-line action each.

-            Applicability and runtime coverage:
-            - Explicitly state applicability across Web / Desktop (Tauri) / VS Code.
-            - If a runtime is not affected, say: “<Runtime>: not applicable — <reason>”.
-            - Remember: backends are separate implementations; Desktop (Tauri) does not reuse Web.
-            - VS Code extension does not require 100% feature parity; many features are intentionally hidden — justify parity expectations.
-
-            Code standards (AGENTS.md):
-            - TypeScript: no `any`, avoid blind casts; prefer precise types and generics.
-            - React: function components + hooks; avoid class components and side-effects outside hooks.
-            - Control flow: no nested ternaries; prefer early returns and readable branching.
-            - Styling: Tailwind v4; use typography.ts and theme variables; avoid ad-hoc inline styles unless justified.
-            - Monorepo: tight diffs; follow local precedent in the touched package/module.
-            - Dependencies: avoid new deps unless justified; if introduced, provide rationale and a standard-library or existing-deps alternative.
-
-            Architecture:
-            - Call out breakages, missing implementations across runtimes/modules, or boundary violations.
-            - Note cross-cutting concerns (errors, logging, accessibility) if missing.
-
-            Precedence:
-            - If local precedent conflicts with global standards, state the deviation explicitly and recommend alignment or a follow-up RFC.
-
-            Format exactly:
-            Must-fix:
-            - <issue> — <brief why> — <file:line-range> — Action: <one-line action>
-            Nice-to-have:
-            - <issue> — <brief why> — <file:line-range> — Action: <one-line action>
-            If no issues, write:
-            Must-fix:
-            - None
-            Nice-to-have:
-            - None
