thincms_update_social_links

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

The description says 'Replace' which implies overwriting the entire set of social links, and mentions 'max 20' constraint. Since no annotations are provided, the description carries the full burden of behavioral disclosure, but it does not detail side effects such as immediate propagation or irreversibility.

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 extremely concise with two sentences that front-load the essential purpose and constraint, followed by a helpful usage hint. No wasted words.

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?

Given the tool's simplicity and detailed schema, the description is largely complete. It explains the replacement action, maximum count, platform options, and template usage. Minor omission: it doesn't explicitly state that it is a full replacement, but the schema's 'full replacement' note covers this.

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 baseline is 3. The description adds value by explaining that each link requires a platform and URL, listing supported platforms, and noting the rendering method, which provides context beyond the schema's parameter descriptions.

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 the tool replaces the site's social media links, specifying the max of 20 and listing supported platforms. This distinguishes it from related tools like thincms_get_social_links.

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 indicates when to use the tool ('Replace the site's social media links') and provides a usage tip ('Use {{social:links}} in the page frame template'). However, it does not mention when not to use it or specify alternatives, but for a simple update tool this is adequate.

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