account_set_tax_default

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

The annotations already disclose that the operation is idempotent and potentially destructive, and the description is consistent with that by mentioning clearing. However, it does not explain what clearing affects, whether an existing default is replaced, or what permissions are required.

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 a single efficient sentence with the core operation front-loaded and no filler. Its terseness is not wasted, though the brevity comes at the cost of useful detail rather than through deliberate compression.

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?

For a destructive account-setting mutation with three undocumented parameters and no output schema, the description is too thin. It omits the clearing semantics, replacement behavior, and any prerequisite or permission context needed to invoke it confidently.

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 carry parameter meaning, but it only addresses the tax code implicitly. It does not explain that omitting taxCode clears the default, nor does it describe accountId or workspaceId beyond their names.

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 states a specific verb and resource: setting or clearing an account's default tax code. It clearly distinguishes the operation from general account update or tax-code maintenance tools, though it does not explicitly name a sibling alternative.

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 gives no guidance on when to use this tool versus update_account or tax-code configuration tools. It also does not state prerequisites, such as whether the tax code must already exist in the workspace.

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