freshrss_add_label

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

No annotations are provided, so the description has the full burden of explaining side effects. It only states the action and does not disclose whether adding the same label twice is idempotent, whether a missing label is created, or what side effects occur. For a mutating tool this is a meaningful 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 a single, front-loaded sentence with no filler, so it is concise. However, it is so terse that it forces the other dimensions to carry missing behavioral, usage, and parameter context, making it not fully appropriately sized for a tool with no annotations.

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?

For a mutating tool with no annotations and no behavioral detail, the description is incomplete. An agent can infer the basic action but not the label lifecycle, error behavior, idempotency, or when this tool is the right choice relative to the many sibling article-management tools.

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 0% per the context signal and the tool description adds no parameter-level guidance. Although the nested schema has brief property descriptions for 'label' and 'article_ids', the main description does not help an agent understand formats, required relationships, or constraints beyond the bare schema names.

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 names the operation ('Add') and the target ('label' on 'articles'), so an agent can tell that this tool associates a label with articles. It is clear and no sibling tool does exactly this, though it does not explicitly compare itself to siblings like freshrss_star_article or freshrss_mark_read.

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?

There is no guidance about when to use this tool, when not to use it, or which alternative to prefer. It also does not mention prerequisites such as whether the label must already exist or whether authentication is required, so usage context must be inferred entirely from the name and schema.

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