update_personal_page

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

No annotations provided, so description must fully disclose behavior. It does not mention whether the update is a full replacement or merge (patch semantics implied by the example but not stated). No mention of authorization, rate limits, or side effects.

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?

Well-structured with a purpose statement, bullet list, and example. Slightly verbose due to full field listing, but clear and front-loaded.

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?

Covers input parameters well, but lacks information about return value, error conditions, or permissions. Given no output schema, this leaves a gap in completeness.

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 0%, but the description exhaustively documents all supported fields with types, structure, and an example. It fully compensates for the minimal schema.

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 title and first sentence clearly state the tool updates personal page branding and graphics. It lists specific fields, distinguishes from meeting-type CSS tools via the note at the end.

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 note explicitly directs users to update_meeting_type for CSS modes and to the dashboard for raw CSS, providing clear alternatives. It does not positively state when to use this tool, but the exclusion is helpful.

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