-## Comments
-
-A comment must carry information the code cannot. If a reader could derive it from the code in front of them, delete it.
-
-Comment the current state. Not what the code used to do, not what changed, not why it changed: git holds that. Where history explains the shape, state the reason instead, so "this used to reimplement the modal internals" becomes "thin wrapper over the shared Modal: duplicating its portal and focus trap is how dialogs drift apart". Future state goes in a TODO with an issue.
-
-Write a comment when it does one of these four jobs:
-
- **Contract.** What a caller must know that the signature cannot say: preconditions, invariants, units, ownership and lifetime, thread-safety, error semantics, side effects. Document the contract of everything a caller outside the file can reach, and nothing else. Goes on the type/method/module as Javadoc, JSDoc, or a docstring.
- **Why.** The constraint the code satisfies, the bug it avoids, the alternative rejected and the reason.
- **Hazard.** "Must stay in sync with X", "order matters because Y", "do not remove, it prevents Z".
- **Map.** A short orientation at the top of a genuinely complex file: what it owns, and what it deliberately does not.
-
-Never write:
-
- A comment that restates the next line. `// Handle drag start` above `handleDragStart` is noise.
- Section banners or position markers: `// --- Types ---`, `// Helpers`, `// =====`.
- Step narration in a function body (`// Step 1:`, `// Then we`). If the steps need labels they need names: extract functions. Numbering a genuinely numbered thing, like a wizard step, is fine.
- Commented-out code. Delete it.
- Doc tags that restate the signature. `@param blob - The blob` says nothing; omit the tag rather than pad it.
- Docs on self-explanatory members with no constraint to state.
-
-Two tests before keeping a comment:
-
- **Delete it.** Is any information lost? If not, it stays deleted.
- **Could a name carry it instead?** A better identifier, an extracted function, or a named constant beats a comment. Prefer the code change.
-
-A comment at the end of a line usually decodes that line, and that is worth keeping: `{0x25, 0x50} // "%PDF"`, `50L * 1024 * 1024 // 50 MB`. The rules that compare a comment against the code below it do not apply there, but a trailing TODO or a trailing bit of history is judged like any other.
-
-A reference is supplementary, never load-bearing: the comment must survive deleting it. `// See #1234` is a dead end; `// saving first loses every annotation (#6865)` is not. Prefer a spec (`RFC 3161`) or CVE where one applies.
-
-A TODO needs an issue, not an owner: `// TODO(#1234): re-enable the gate once account syncing lands`. If it is not worth an issue, it is not worth a TODO. A question is not a TODO.
-
-A comment block over ~12 lines outside a file or type header usually means the code needs restructuring, or that the prose is product documentation and belongs in the docs repo.
-
-`task comment-lint` checks the mechanical part of this on the lines you add, and runs inside `task pre-commit`. Reasoning, worked examples and the linter's own rules: @devGuide/CODE_COMMENTS.md

 - Avoid nested functions and nested classes unless the language construct requires them.
 - Prefer composition to inheritance when combining concepts.
 - Avoid speculative abstractions. Add a layer only when it removes real duplication or clarifies lifecycle.
- Comments follow the repo-wide rules in the "Comments" section above.
+- Add comments sparingly and only when they explain non-obvious intent.

 #### Python Typing and Models
 - Deserialize into Pydantic models as early as possible.
@@ -42,7 +42,6 @@ Please make sure your Pull Request adheres to the following guidelines:
 - Keep commits atomic. One commit should contain one change. If you want to make multiple changes, submit multiple Pull Requests.
 - Commits should be clear, concise, and easy to understand.
 - References to the Issue number in the Pull Request and/or Commit message.
- Every comment in the diff should say something the code does not. See [Code comments](devGuide/CODE_COMMENTS.md); `task comment-lint` checks the mechanical part.
