add_confluence_page_label

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

There are no annotations, so the description carries the full burden of disclosing side effects. It states the additive write action, but does not mention whether duplicate labels are tolerated, whether existing labels are replaced, required permissions, or what the response indicates. This mirrors the gap seen in mutation tools that only assert the action.

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 two short sentences, front-loaded with the core action. The second sentence adds mild context about labels without becoming filler, and there is no unnecessary formatting or repetition.

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 simple two-parameter mutation with full schema coverage and no output schema, the description is largely complete: it states what the tool does, what it operates on, and why labels matter. It omits response details and edge-case behavior, but those are not essential for a correct first invocation.

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 applies: the schema already documents both pageId and labels, including label prefix semantics. The description adds no parameter-specific detail beyond what the schema provides.

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 opens with a specific verb and object: 'Adds one or more labels to a Confluence page.' This clearly distinguishes the tool from sibling operations like add_confluence_comment, update_confluence_page, or list_confluence_page_labels, so an agent can identify the correct resource and action.

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 second sentence explains why labels are useful, implying the tool is for categorization purposes, but there is no explicit guidance on when to choose this over alternatives or when not to use it. Sibling tools such as list_confluence_page_labels suggest read-vs-write alternatives, but the description does not mention them.

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