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

Annotations already declare readOnly=true, destructive=false and openWorld=false, so the safety profile is covered without description help. The description adds the return shape ('most relevant guides with links'), which is useful given no output schema, but says nothing about result count, ranking, or how many guides come back.

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 sentences with the usage trigger front-loaded before the enumeration of covered topics and the return statement. Every listed topic works as a retrieval cue, so none of the enumeration is wasted.

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 one-parameter, annotation-covered search tool with no output schema, this covers what an agent needs: when to call it, what topics it spans, and what comes back. Only the result-set characteristics (count, ranking, links-only vs. summary) remain unspecified.

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?

Single parameter with 100% schema description coverage, so the schema carries the load and baseline 3 applies. 'Any question about clipping' in the description does add a hint that the query is free-form natural language rather than a keyword, but no format or length guidance is given.

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 retrieval action ('search' implied by name, 'returns the most relevant Clipping Daily guides') over an enumerated topic space. The topic list ('how to start clipping, payout caps, clipping agencies...') clearly signals a documentation-search tool, which implicitly separates it from the calculation siblings, but it never names those siblings explicitly.

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?

'Use for any question about clipping' gives a clear triggering condition, reinforced by a concrete topic list that maps to realistic user questions. It lacks any when-not guidance or explicit hand-off to estimate_clipping_earnings / get_clipping_pay_rates for numeric questions.

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