context.select_all

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

Does not disclose whether previous selection is cleared, if actions are additive, or any side effects. With no annotations, the description bears full responsibility for behavioral context but is insufficient.

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?

Single sentence with no wasted words. Could benefit from additional details without becoming verbose.

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?

Adequate for a simple selection tool with one param, but lacks behavioral details that would help an agent use it correctly alongside related tools.

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; the parameter title 'Selection action applied to every scene object' is the only context. Description adds no additional meaning to the enum values.

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 (select, deselect, invert) and resource (all scene objects). Distinguishes from sibling tools like context.select_objects by explicitly targeting all objects.

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?

No guidance on when to use this tool vs alternatives (e.g., context.select_objects for specific objects). Description lacks context about prerequisites or selection mode.

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