clear_selection

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

Discloses basic behavior: clears selection, optional layer_name. No annotations exist; no extra context on permissions, side effects, or return values.

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?

One sentence, 14 words, front-loaded with action. No unnecessary words.

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?

Simple operation with optional parameters; mostly adequate. Minor gap: map_name not explained, and output schema exists but no return value description needed.

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 has 0% description coverage. Description only explains layer_name and its omission behavior; map_name is not mentioned at all. Insufficient for a 2-param tool.

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?

Clearly states the verb 'clear', resource 'selection on a layer', and scope (one layer or all layers if omitted). Differentiates from sibling tools like select_features.

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?

Tells when to use: clearing selection on one or all layers. Implied when not to use for other operations like selecting features, but no explicit exclusions or alternatives.

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