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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false and openWorldHint=true, so the safety and idempotency profile is fully covered by structured data. The description adds the sequencing context (fetch options before choosing settings) but says nothing about what the call actually returns, latency, or failure modes when a connection is stale.

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?

Two tight sentences, front-loaded with the purpose and followed by the prerequisite. Every clause carries information the agent needs; there is no filler or restatement of the title.

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?

There is no output schema, so the description carries the burden of telling the agent what comes back — and it only gestures at 'privacy and interaction settings' without indicating the fields or shape of the creator options. Combined with no mention of what happens when the TikTok connection lacks those permissions, it is adequate but leaves a real gap for a tool whose return value is the whole point.

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% and both parameters already carry a pattern plus the warning that they are exact Company-tool IDs, so the baseline would be 3. The description goes one step beyond by naming the specific source tool for the connection id (company_list_channels), which is actionable provenance the schema does not supply.

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?

The description uses a specific verb ('Read') and a specific resource ('current TikTok creator options for a Workspace connection'), which is unambiguous among siblings — no other tool retrieves TikTok creator options. It does not explicitly name a sibling it might be confused with, but the resource is distinctive enough that the agent can distinguish it 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?

It states a clear usage context ('before selecting privacy and interaction settings'), which tells the agent this is a prerequisite read step rather than an end action. It also routes the agent to company_list_channels for the connection id. It stops short of explicit exclusions (e.g., when not to call, or behavior for non-TikTok connections).

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