get_content_changelog

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

The description discloses that the tool is 'Read-only' and 'Returns paginated JSON array with pagination.hasMore flag.' This provides essential behavioral information beyond the schema, especially given no annotations are provided. No contradictions.

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 concise with four well-structured sentences. Each sentence serves a distinct purpose: stating the function, outlining filters, providing usage guidance, and noting read-only and return format. No redundancy.

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 has 5 parameters and no output schema, the description covers purpose, usage, filtering, return type (paginated JSON array with hasMore flag), and safety. It is nearly complete, though a bit more detail on the output structure could be beneficial.

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 baseline is 3. The description adds value by giving examples of category values (e.g., blog, docs) and mentioning the pagination flag, 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's purpose: 'Get detected content changes over time — new URLs, removed URLs, moved URLs.' It uses a specific verb ('Get') and resource ('content changelog'), and differentiates it from sibling tools like get_content_dashboard by noting that it shows changes rather than current state.

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 says 'Use this instead of comparing full runs when you only need to know what changed' and 'Complements get_content_dashboard which shows the current state.' This provides clear context on when to use the tool, though it doesn't explicitly state when not to use it.

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