Chat Configure

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

With no annotations, the description carries the full burden and delivers substantive mutation semantics: chat_mode wholesale-replaces settings, partial custom calls merge and preserve omitted fields, and a bare call is rejected because it would reset everything to default. It stops short of 5 only because permission/auth requirements and the exact reset scope are unstated.

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

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

Front-loaded purpose sentence, then two tight bullets that each encode a distinct rule with no filler. The nested emphasis formatting is slightly heavy for the amount of content, but every sentence carries a usable constraint.

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

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

For a mutation tool with no annotations and an output schema (so return values needn't be described), the description covers mutually-exclusive modes, merge behavior, and rejection cases. Only auth/permission context and the full list of affected settings are missing, leaving a minor gap.

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

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

Schema coverage is 0%, so the description must supply all meaning and does: it names the chat_mode presets, explains goal as a custom persona that selects the CUSTOM goal, gives the response_length options, and confirms notebook accepts a name or ID. Every parameter is semantically documented beyond the bare schema.

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

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

States a specific verb and resource: 'Configure a notebook's chat behavior,' which is clearly a configuration action distinct from chat_ask/chat_start/chat_status siblings. It never names a sibling explicitly, so it stops short of a 5, but an agent can place it in the chat family without opening the schema.

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

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

Explicitly lays out when each path applies: a preset via chat_mode replaces the whole block and is rejected if combined with goal/response_length, while goal/response_length set a custom config that merges on partial calls and is only rejected when the call is bare. This is a precise when/how-not map for a 4-param tool.

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