RentReboot Apartment Search

Change my apartment search

update_search_preferences

DestructiveIdempotent

Change the connected renter's saved alert search. Send only the fields to change; everything else stays. Saves exactly like the RentReboot preferences page, so its rules apply (for example a search always keeps at least one neighborhood). For a new account, set city together with neighborhoods once; after that the market cannot change here. Confirm the change with the renter first. Weekly recap pauses individual alerts.

`amenities`	No	Replaces the whole amenity list
`bathrooms`	No
`noFeeOnly`	No
`moveInDate`	No	YYYY-MM-DD, or null for no date
`subwayLines`	No	NYC only; replaces the whole list
`neighborhoods`	No	Names or ids from find_search_neighborhoods

A3.9/5.0

Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With destructiveHint=true and idempotentHint=true already declared, the description usefully adds partial-update semantics ('everything else stays'), inheritance of the preferences-page rules, the new-account city constraint, and the alertFrequency/weekly-recap interaction. It does not contradict annotations; 'everything else stays' refers to unsent fields, consistent with the schema's list-replacement notes.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Front-loaded with the core action and partial-update rule, then layered constraints and a caution. Dense but almost every sentence carries actionable content; slight overload from cramming several rules into one block.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a 17-parameter mutation tool with nested objects and no output schema, the description covers the critical behaviors: partial update, rule inheritance, new-account constraint, and confirmation requirement. It could note the response/return behavior, but the destructive and idempotent annotations plus the rules given make it largely sufficient.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is moderate (59%) and the schema already documents many params (city, channel, minRent, amenities, neighborhoods, alertFrequency, strictMoveInDate). The description adds real meaning for city ('set once, market cannot change here') and alertFrequency ('weekly recap pauses individual alerts'), but leaves many parameters undiscussed. Baseline 3 is fair.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific verb and resource: 'Change the connected renter's saved alert search.' That distinguishes it from read-oriented siblings like get_search_preferences and from set_apartment_alerts, though no sibling is named explicitly. An agent can identify what the tool mutates.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Gives clear operational context: send only fields to change, set city with neighborhoods once for a new account, and confirm with the renter before applying. It lacks an explicit pointer to the read counterpart (get_search_preferences) for inspection beforehand, so it stops short of naming alternatives.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
