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

Goes well beyond the annotations (readOnlyHint=false, openWorldHint=true, destructiveHint=false) by disclosing the side-effect profile (no portal access, no invitation), the authorization requirements, the confirmation-per-call default, the fact that it reaches other people, and the required API key scope. This is exactly the extra behavioral context the description should carry.

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?

Purpose is front-loaded, but the confirmation guidance is stated twice ('By default you confirm each call; you can switch that off' and 'confirm with the user before each call'), and the repeated 'TaxDome:' prefix adds noise. It is serviceable but not tight.

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 carries the return-value burden, and while it does not describe the response, it fully covers the auth model, confirmation behavior, and the account/contact creation semantics an agent needs before calling. Only the result shape is left unstated.

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%, so the schema already documents all five parameters, setting the baseline at 3. The description maps the type field to 'Individual or Company' and mentions 'name and email', which lightly reinforces the schema but adds little genuinely new meaning (company_name is not spelled out).

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 ('Create a client account of type Individual or Company with its first contact') and even explains the two-step effect (account then first contact from name and email). This cleanly separates it from siblings like taxdome_get_account, taxdome_list_accounts, and taxdome_create_job.

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?

Gives clear prerequisites (firm owner, admin, or Manage accounts access right) and clarifies what this is NOT for (it does not grant portal access and does not invite anyone), which helps an agent avoid misusing it. It stops short of naming a specific alternative sibling for related actions, so it falls just below explicit when/when-not routing.

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