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

Annotations already establish readOnlyHint=true, idempotentHint=true, destructiveHint=false, and openWorldHint=false. The description adds useful workflow context beyond annotations: the tool renders a confirmation card only after record resolution and before/after preparation, and the actual write still requires confirm=true.

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 description is two tight sentences with the purpose and prerequisite front-loaded. Every sentence adds workflow information without repetition or filler.

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 20-parameter nested tool with no output schema and no schema descriptions, the description is far too thin. It covers the high-level confirmation workflow but does not explain how confirm_tool and confirm_args drive the card or what the many display fields mean.

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?

There are 20 optional parameters with 0% schema description coverage, so the description must carry the burden. It only mentions before/after values and leaves critical fields such as confirm_tool, confirm_args, impact, details, labels, and messages 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: renders a TrackingTime confirmation card for sensitive changes. This clearly distinguishes it from write tools and from other render_* siblings such as render_task_list or render_project_summary.

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 explicit sequencing: use after resolving the exact record and preparing before/after values, and notes that the target write tool must still require confirm=true. It does not state when not to use it or name an alternative confirmation mechanism, so it falls short of a 5.

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