Settings: update postingaccount

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

Annotations already declare readOnlyHint=false and destructiveHint=false. The description adds minimal value by stating 'WRITE · updates data' and 'modifies existing master data in place', but it does not disclose error handling, authentication needs, or rate limits. The endpoint URL is provided but not behavioral.

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 short and uses emoji/bold for emphasis. It includes the endpoint but repeats the tool name. It is concise and front-loaded with the purpose, though slightly redundant.

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 should explain return value or success indicators, but it does not. It also lacks context about the tool's role among siblings (e.g., only for existing records). The description is too minimal to be considered complete.

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 coverage is 100%, so the schema fully describes all three parameters. The description adds no additional details beyond what the schema provides, thus baseline score of 3 is appropriate.

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 'Update a postingaccount' with a verb and resource. However, it does not explicitly distinguish from sibling tools like settings_add_postingaccount or settings_get_postingaccounts, though the verb 'update' inherently differentiates it from creation or retrieval.

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?

No guidance on when to use this tool versus alternatives (e.g., settings_add_postingaccount for creation, settings_get_postingaccounts for listing). The description lacks any context about prerequisites or typical scenarios.

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