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

Annotations (readOnly=false, openWorld=true, non-idempotent, non-destructive) already flag a stateful, side-effecting tool; the description adds the crucial behavioral picture beyond them: it pauses and returns pending_action for creator allow/deny, consumes tokens, can write files and run commands, keeps its own conversation history, and permits mid-flight steering via new messages.

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?

One dense paragraph, but front-loaded with the identity of the operator before the behavioral and gating details. Nearly every clause carries information, though the sentence is long enough that a reader must parse carefully.

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?

With no output schema, the description covers the return contract (answer in its own words, pending_action on tool use), the continuation mechanism, the availability gate, and the approval loop — everything an agent needs to invoke and re-invoke correctly.

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 100%, so the baseline is 3, but the description adds real semantics beyond the schema: conversation_id continues an existing thread and a new message to an in-flight conversation steers it, plus the wait_seconds/work-in-progress retry pattern.

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?

Names a specific verb+resource (talk to Switch's unrestricted operator) and immediately scopes it as the unrestricted/mature Studio chat mode running on BytePlus with its own workspace, tools and skills. An agent can distinguish this from generic chat or generation siblings 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?

States concrete accepted inputs (brief, question, research ask, coding task), names the companion approval tool decide_switch_unrestricted_action, and gives an explicit when-not condition: accounts without unrestricted mode get NOT_ALLOWED. The 'nothing here is sent to Claude' line implicitly routes non-unrestricted work elsewhere.

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