x_api_create_webhooks_stream_link

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

With no annotations, the description fully carries the transparency burden. It discloses mutating/high-risk behavior, bearer-token requirement, environment-selection semantics, common failure conditions, expected response shape, and safety warnings. This goes well beyond minimal expectations and helps the agent anticipate side effects.

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?

The description is well-organized with labeled sections, making it scannable. However, it is verbose and contains redundancy: 'Create stream link' appears both as the opening and again under 'Use when'. Some details, like 'unknown' in the parameter format, add little value.

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?

Given 13 parameters, no annotations, and no output schema, the description is remarkably complete. It includes required permissions, environment selection, parameter constraints, expected response structure, failure conditions, safety warnings, recommended tools, and an example. This is sufficient for an agent to invoke the tool with confidence.

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 description coverage is 0%, so the description must compensate. It explains path vs query placement for webhook_id and tweet/expansion fields, defines the scopeTenantId/scopeUserId/scopeAccountId selection behavior, and clarifies credentialKey's role. This adds substantial meaning 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?

The description opens with the specific action 'Create stream link', which clearly identifies the tool's operation and aligns with the tool name. It distinguishes from the sibling get/delete stream-link tools by verb, though it does not elaborate on what a 'stream link' represents in the webhook context.

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?

The description provides explicit 'Use when' and 'Do not use when' sections, and recommends alternative tools like x_schema_discovery and x_query_suggestion for exploration. It also lists prerequisite and follow-up tools, giving practical guidance, although the 'Use when' clause largely restates the purpose.

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