📝 WalkthroughWalkthroughAdds eight mailbox rule shortcuts with semantic parsing, validation, API encoding and decoding, unknown-field preservation, pagination, lifecycle operations, reordering, tests, registration, and documentation. ChangesMailbox rule shortcuts
Estimated code review effort: 5 (Critical) | ~90 minutes Mergeability Score: 🟠 High · up to Updating mailbox rules may erase fields the shortcut does not model, causing unintended rule-data loss; listing rules can also hang on malformed pagination responses, and some invalid condition values are silently discarded. These current-head correctness and availability risks should be fixed or explicitly accepted before merging. Sequence Diagram(s)sequenceDiagram

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Handle non-string condition values, and align both JSON decoders.
parseRuleConditionJSONObject reads value with m["value"].(string) only. A JSON condition such as {"field":"subject","operator":"contains","value":123} silently drops the value, and the user then sees "requires a non-empty value". The action path already normalizes non-string values with fmt.Sprint and decodes with UseNumber. Use the same approach for conditions so numbers keep their exact text.

🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win
Bound the pagination loop.
The loop repeats while the API reports has_more and returns a token. If the API echoes the same page_token, the loop never ends and the command hangs. Add a page cap and stop when the token repeats.

🗄️ Data Integrity & Integration | 🟠 Major | ⚡ Quick win
The update PUT body drops unmodeled fields from the current rule.
encodeRuleSpec emits only name, is_enable, ignore_the_rest_of_rules, condition, action, and rule_id. mergeRuleUpdate sends that body with PUT on the rule item path, so any other top-level field returned by the API for that rule is absent from the request and can be cleared server side. Extra keys inside otherwise-known condition and action items are also lost, because decodeRuleConditions and decodeRuleActions do not record them as unknowns.
makeRuleToggleShortcut already avoids this by starting from copyMap(env.Raw). Apply the same base here so the merge only overwrites the fields the CLI models.
