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

Annotations already declare readOnlyHint=true, so the safety profile is covered. The description adds value by disclosing the return shape (id, title, version, link), which matters because there is no output schema. It says nothing about ordering, pagination beyond the limit parameter, or whether sub-pages/archived pages are included.

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?

Two short sentences with no filler; the purpose is front-loaded and the return contract follows. Nothing is redundant, though it is so terse that the absence of usage guidance is a size problem rather than a length problem.

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 read-only list tool with full schema coverage and readOnlyHint annotations, the description covers purpose and return fields adequately. The only meaningful gap is pagination/ordering behavior and how results relate to confluence_search.

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%, with limit, account, and space_key all documented in the schema, including an example space key. The description adds no parameter meaning beyond that, so the baseline of 3 applies.

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?

States a specific verb and resource with scope: 'List pages in a Confluence space.' An agent can tell this is a space-scoped enumeration rather than a single-page fetch. It does not, however, name or distinguish itself from siblings like confluence_search or confluence_get_page.

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 contains no when-to-use guidance and no exclusions. It never tells the agent to prefer confluence_search when looking for pages by title/content, or confluence_get_page when the id is already known, so the routing decision among four read-oriented siblings is left entirely to inference from the tool name.

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