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

With readOnlyHint=true already declaring the safety profile, the description adds useful behavioral context beyond annotations: what the records contain, that it is a lookup step for assigneeId, and the important fallback behavior when workspaceId is omitted (credential's workspace is used). Pagination or result-size limits are not mentioned.

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?

Three short sentences, front-loaded with purpose, then the return fields, then the parameter default. Zero filler; each sentence delivers distinct information.

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-optional-parameter read tool with no output schema, the description covers what it returns (id, nombre, email), why to call it (assigneeId), and the default behavior of the only parameter. Nothing needed to invoke it correctly is missing.

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 0%, so the description must carry the parameter burden, and it does: workspaceId is explained as optional, as the workspace to operate in, as enumerable via list_workspaces, and as defaulting to the credential's workspace. That fully removes ambiguity about what happens when the single parameter is omitted.

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 concrete verb and resource (lists the assignable members of the workspace) and names the fields returned (id, name, email), which tells the agent exactly what data this yields. It does not explicitly contrast against any of the many sibling list_* tools, but the 'assignable members' scope is distinctive enough to disambiguate.

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 a clear operational trigger ('necesario para obtener el assigneeId') so the agent knows this is the prerequisite call before assigning issues. It also names list_workspaces as the way to discover valid workspaceId values. It lacks an explicit 'do not use when' clause.

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