idea_create

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It states the action and allowed content types, but it does not explain permissions, return behavior, idempotency, duplicate handling, or the scope of side effects. For a mutating tool, this is a significant transparency gap.

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, front-loaded with the main purpose, and avoids unnecessary filler. The second sentence is compact but slightly inaccurate due to the unsupported 'tags' mention, which prevents a perfect structural score.

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 fully self-descriptive and the tool is fairly simple, so the description does not need to explain every parameter. Still, the missing guidance on when to use this tool versus post_create, the misleading 'tags' reference, and the lack of behavioral detail leave noticeable gaps. It is adequate but not comprehensive.

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 little beyond restating text, images, and services, and it mentions 'tags' even though no tags parameter exists in the schema and additionalProperties is false. This could mislead the agent into sending an invalid property.

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 action and resource: 'Save an idea to the Buffer ideas board for later use.' This clearly conveys what the tool does and separates it from post_create by emphasizing deferred use. However, it does not explicitly name or contrast sibling tools, so the differentiation is implied rather than fully articulated.

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 phrase 'for later use' implies this tool is for capturing drafts or ideas rather than publishing, but the description does not explicitly say when to use it versus post_create or other siblings. There are no exclusions or alternative recommendations, leaving the agent to infer routing from context.

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