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

Annotations already declare readOnlyHint=true and openWorldHint=false, so safety is covered. The description adds a genuine behavioral trait — templates are non-binding suggestions requiring user confirmation before cloning — but the enumerated return fields duplicate the existing output schema rather than adding context.

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 opening clause is well front-loaded, but the second sentence is a run-on mixing clone-vs-build guidance with a tangential aside about audio requests. The return-field enumeration is padding given the output schema exists.

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 read-only, 3-parameter list tool with a full output schema and complete annotation coverage, the description supplies adequate context: what the gallery is, and what to do with the results. The redundant return-field list is a minor blemish rather than a gap.

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 limit, search, and category are fully documented in the schema, including the 'raise it only if the user asked for more' and 'omit unless the user named a field of work' guidance. The description contributes nothing beyond that baseline.

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 ('Browse the template gallery — ready-made workflows') and implies a boundary against create_workflow_from_template by framing entries as suggestions rather than committed artifacts. It is clear what the tool returns, though the sibling differentiation is implicit rather than named.

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?

Gives downstream usage guidance ('tell the user which one would fit and ask whether to clone it or build a new workflow') and one odd exclusion ('asking for audio is not choosing a template'), but never states plainly when to call this versus list_workflows or create_workflow_from_intent. Usage is implied rather than specified.

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