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

Annotations already establish read-only, idempotent, non-destructive, closed-world behavior. The description adds that it works from 'prepared task records' and produces a view, but it does not describe the returned view, formatting behavior, or what inputs are required to make rendering succeed.

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 short sentences with no filler, and the core purpose is front-loaded before the usage note.

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 tool with seven undocumented optional parameters and no output schema, the description is too sparse. It explains when to call it but not how to construct the task list view or what display metadata such as metrics and warnings are for.

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% across 7 parameters, so the description must compensate but largely does not. 'Prepared task records' vaguely points to the tasks parameter, but title, eyebrow, metrics, subtitle, warnings, and tasks_title are entirely unexplained.

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: it renders a TrackingTime task list view from prepared task records. This distinguishes it from data-fetching siblings such as list_tasks, though it does not explicitly distinguish itself from other render_* tools like render_entity_list.

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?

It gives clear usage context: 'Use after listing project, user, or account tasks.' That tells the agent this is a presentation step, but it names no exclusions or specific alternative render tools.

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