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

No annotations are provided, so the description must disclose behavior. It mentions the permission requirement (crm:write) and the return value ('Returns the created resource with its absolute url'), which are useful. However, it does not disclose side effects (e.g., potential duplicates, required field validations, or error conditions). For a mutation tool with zero annotation coverage, more detail would be expected.

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 three sentences, highly concise, and front-loaded with the core purpose. Every sentence adds useful information: purpose, required field, permission, and return type. No fluff or redundancy.

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?

The description explains the return format, which is good since there is no output schema. However, it leaves the optional parameters (domain, website) entirely unexplained, and does not mention any uniqueness or validation rules. For a create operation with 4 parameters, an agent would benefit from more detail on what constitutes a valid company (e.g., is name unique? does domain need to be a URL?). The description is minimal but covers the core, so it is just adequate.

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 100%, but the parameter descriptions are tautological (e.g., 'name', 'domain'), providing no meaning. The description only restates that name is required, which is already in the schema. It does not explain what domain or website represent or any format constraints. With such unhelpful schema descriptions, the tool description should compensate, but it does not add value beyond the 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 clearly states the tool's purpose: 'Creates a company in the tenant CRM.' It uses a specific verb (creates), resource (company), and context (tenant CRM), which differentiates it from sibling tools like commsharbor_crm_companies_delete, get, list, and update. An agent can immediately understand this is the creation operation.

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 implies usage for creating a company, which is clear from the context. It also states a prerequisite: 'Needs crm:write on the organization,' which is a useful guideline. However, it does not explicitly contrast with sibling create tools (e.g., contacts, deals), though the resource name makes this evident. No exclusions or alternative routing are given, so it is slightly above baseline but not fully explicit.

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