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

Annotations already declare readOnlyHint and closed-world scope, so the safety profile is covered. The description adds genuinely new behavioral detail absent from structured fields: a hard cap of 5 results and the fact that matches include public URLs. It stops short of saying what happens when nothing matches or how to retrieve more than 5.

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 compact sentences with no filler; the core action and the input example come first, with the return shape second. Slightly terse given the open questions it leaves, but nothing 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?

With no output schema, the description must cover returns, and it does partially (up to 5 matches, public URLs). Gaps remain for an agent deciding between this and list_program_templates: no statement on equipment filtering behavior, zero-result behavior, or scope relative to the sibling tools.

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%, so both parameters are already documented. The description adds example goal values ('strength', 'marathon') that clarify expected input format, but says nothing about the optional equipment parameter or how it constrains results. Baseline 3 applies when the schema carries the semantics.

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 ('Find Superset's free training program templates') plus the goal-scoped nature of the search, which is more precise than the title. It does not, however, distinguish itself from the sibling list_program_templates, which an agent could easily confuse it with.

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 examples ('strength', 'marathon') imply the kind of input to supply, giving implied usage guidance. There is no explicit when-to-use vs. when-not, and no mention of how this differs from list_program_templates or compare_with, leaving the routing decision to inference.

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