Behavior2/5

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

No annotations are provided, so the description carries the full behavioral burden. It does not disclose whether this mutates project state irreversibly, whether it is undoable, whether it also deselects items inside the range, or what happens when there is no active selection.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness3/5

Is the description appropriately sized, front-loaded, and free of redundancy?

It is a single front-loaded sentence with no waste, which is appropriate in shape. However, brevity here borders on under-specification rather than genuine conciseness, since the sentence conveys almost nothing the name did not.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a zero-parameter, low-complexity tool with no output schema, the description is minimally viable. It omits the one useful piece of context an agent would want: how this relates to set_time_selection and what state it leaves the project in.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The tool takes zero parameters, so the baseline of 4 applies. The description correctly implies a no-argument action, and there is nothing parameter-related left to document.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose3/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a verb ("clear") and a resource ("time selection"), but it is essentially a restatement of the tool name and adds no scope detail. An agent can infer the effect, yet nothing distinguishes it from the neighboring set_time_selection beyond the antonym in the name.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

There is no when-to-use guidance, no mention of set_time_selection as the complementary operation, and no note about state preconditions (e.g., what happens if no time selection exists). The agent must infer the usage context purely from the name.

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