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

Annotations already declare readOnlyHint=true and destructiveHint=false, so the safety profile is covered. The description adds scope (what data comes back) and an auth prerequisite (Cotlet API key with access to this app), which is useful context beyond the annotations, but nothing about pagination or result limits.

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 first two sentences restate the same content ('One account with its contacts, open jobs and open requests' vs. 'Returns one account with its contacts, the jobs that are in progress and the client requests still open'), which is wasted space. The 'TaxDome:' prefix also duplicates the title rather than front-loading the distinctive scope.

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 burden of describing returns, and it does so (account, contacts, open jobs, open requests). The single required parameter is covered by the schema. A note on result size or filtering would round it out, but nothing essential is missing.

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% and the single account_id parameter is fully documented in the schema (including its provenance from list_accounts). The description adds no parameter syntax or format detail, so the baseline 3 applies.

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 (get) and resource (account), and specifies the payload it returns: contacts, in-progress jobs, and still-open client requests. The word 'one' implicitly distinguishes it from list_accounts, so an agent can differentiate them, though the sibling is never named.

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 a clear usage trigger: 'Use it before writing to a client so your agent sees what they were already asked.' That is genuine when-to-use guidance, but there is no explicit when-not and no routing to the list_accounts or get_job alternatives.

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