Poem

🐰 I nibble lines and tidy prose,

Docstrings planted in tidy rows.
A version nestled, safe and small,
The scout is clearer — ready to call.
Hooray, the rabbit hops and stalls!

QUOTATION MARK (U+2019); replace that character with the standard ASCII
apostrophe (U+0027) so the docstring becomes "Slack users' watchlists: author

where it appears (search for the exact text "Slack users’ watchlists") to fix

419-419: ⚠️ Potential issue | 🟡 Minor | ⚡ Quick win

Replace smart quote with ASCII apostrophe to fix RUF002 lint failure.

Line 419 contains a RIGHT SINGLE QUOTATION MARK (') in "user's" instead of a plain ASCII apostrophe ('). This causes the Ruff RUF002 lint check to fail.

🔧 Proposed fix

-    """Post the user's watchlist entries or an empty-state hint."""
+    """Post the user's watchlist entries or an empty-state hint."""
