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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is fully covered without description help. The description adds nothing beyond that - no pagination behavior, no result caps, no statement of what filtering combination is required (all optional).

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?

One short front-loaded sentence with the searchable dimensions stated early. The trailing 'with flexible filtering' is filler that does not add information, keeping it just below a top score.

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?

Six optional parameters with no required inputs and no output schema mean the agent must know what a result set looks like and how many come back by default - neither is stated in the description. Adequate for calling the tool, but short of what a conditional-filter search tool should disclose.

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 coverage is 100%: every parameter, including defaults for page/size, sort format, partial matching for search_name, and the valid status enum, is documented in the schema. The description only restates three filter dimensions, so it adds no syntax or semantics beyond the structured fields - baseline 3.

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?

Names a specific verb ('Search') and resource ('experiments') plus the three filter dimensions (name, status, budget group), so the operation is unambiguous. It does not distinguish itself from nearby siblings such as search_experiment_recipes or manage_experiment, so an agent still needs to infer which experiment tool fits.

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?

There is no statement of when to use this tool rather than manage_experiment, experiment_performance_stats, or search_experiment_recipes, and no prerequisites or exclusions. 'Flexible filtering' implies broad applicability but provides no decision criteria.

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