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

With no annotations provided, the description carries full disclosure burden. It successfully declares 'Read-only' safety status and describes return format ('paginated JSON array with pagination.hasMore flag'), which is critical given no output schema exists. Minor gap: no mention of rate limits or data retention periods.

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?

Four sentences efficiently structured: purpose → filters → usage guidance → output format. Each sentence earns its place with zero redundancy. Read-only status and pagination details are essential given missing annotations/output schema.

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?

Fully complete for a 5-parameter tool with no annotations or output schema. Covers purpose, filtering capabilities, sibling differentiation, safety (read-only), and response structure (pagination flag). No output schema means describing return format in description was necessary and delivered.

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 has 100% description coverage, establishing baseline 3. The description adds contextual framing that competitorId and category function as filters ('Filter by competitor and/or content category'), but does not need to repeat parameter syntax already well-documented in schema.

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 specific verbs ('Get detected content changes') and enumerates exact change types tracked (new URLs, removed URLs, moved URLs). It explicitly distinguishes from sibling get_content_dashboard ('Complements get_content_dashboard which shows the current state') and contrasts with manual full-run comparison.

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?

Contains explicit usage guidance: 'Use this instead of comparing full runs when you only need to know what changed' establishes when-to-use, and 'Complements get_content_dashboard which shows the current state' clearly positions against a specific sibling alternative.

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