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

Annotations already declare readOnlyHint, idempotentHint, closed-world and non-destructive, so the safety profile is covered. The description adds behavioral context the annotations do not: the field set returned and the non-obvious fact that every listed task has at least three catalog candidates. It stops short of describing pagination or result ordering.

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, front-loaded with the verb and resource, then the optional filter. The middle sentence about "at least three catalog candidates" is specific but of uncertain relevance to selection, slightly diluting an otherwise tight definition.

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 compensates by naming the fields returned, and the annotations cover the read-only/idempotent profile. For a zero-required-parameter listing tool this is close to complete, though return shape (ordering, volume) is not described.

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 description coverage is 0%, but the single parameter is a self-documenting enum of eight categories. The description confirms the filter is optional ("Optionally filter tasks by category"), which matches the schema's non-required status but adds no syntax or semantics beyond what the enum already conveys. Baseline 3 is appropriate.

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?

The description states a specific verb and resource ("List Agenlify task IDs") and enumerates the payload fields returned: preparation checklists, expected outputs and review requirements. Sibling differentiation is not addressed, but the siblings (get_agent, search_agents) operate on a different resource entirely, so confusion is unlikely. Clear and specific, just no explicit routing language.

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?

Usage is only implied: the tool returns a task catalog with an optional category filter, which suggests it is the discovery entry point for tasks. There is no statement of when to use it versus alternatives, and no prerequisites or exclusions. Adequate but with a clear gap.

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