Update Account

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

With no annotations provided, the description carries full responsibility for behavioral disclosure. It only states 'Update a Tag Manager account's settings' without mentioning that it is a partial update, that it fails with a stale fingerprint, or what permissions are required. This is minimal transparency for a mutation tool.

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 focused sentence with no filler. It front-loads the action ('Update') and clearly names the target resource, making it easy for an agent to parse quickly.

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 input schema is rich (100% parameter coverage) and an output schema exists, so the description need not explain return values or parameter details. However, it lacks behavioral context such as partial-update semantics and optimistic concurrency, which are important for correct invocation despite being partially encoded in the fingerprint parameter description.

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 baseline is 3. The description adds no extra parameter meaning beyond the schema; the account object, account_id, and fingerprint are already well-documented in the input schema. The description does not compensate for or add to that coverage.

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 uses a specific verb ('Update') and resource ('a Tag Manager account's settings'), which clearly identifies the tool's function. It distinguishes itself from sibling tools like list_accounts, get_account, and update_container by explicitly targeting account settings.

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 no guidance on when to use this tool versus alternatives, no prerequisites, and no mention of needing an existing account or using the fingerprint for concurrency control. The name implies update usage, but the description itself gives no explicit context or exclusions.

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