Idempotent

Adjust the terminal size of an active session by setting its columns and rows to exact values.

Instructions

Resize the session's terminal to cols x rows.

Tool call template

Replace each placeholder with a value matching the input schema. Only required parameters are included; add optional parameters as needed.

TDQS

B3.4/5.0
Behavior2/5

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

Annotations already provide idempotentHint=true and destructiveHint=false, so the safety profile is known. However, the description adds no additional behavioral context such as side effects, error behavior, or interaction with existing terminal content. It only restates the action without enriching transparency.

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

Conciseness5/5

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

The description is a single, concise sentence that front-loads the action and target. Every word earns its place, and there is no verbose or redundant information.

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?

The tool is low complexity, but the description lacks return value information (no output schema) and doesn't mention potential failure modes such as invalid dimensions or non-existent session IDs. It is adequate for a simple resize but leaves open questions about observable effects.

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

Parameters2/5

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

Schema description coverage is 0%, so the description must compensate. It clarifies 'cols' and 'rows' as dimensions via 'cols x rows,' but it does not explain 'sid' beyond the implication from 'session's.' No constraints, bounds, or format details are given, leaving gaps in parameter understanding.

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

Purpose5/5

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

The description clearly states the verb 'Resize' and the resource 'session's terminal' with the target dimensions 'cols x rows.' It is distinct from sibling tools like close, snapshot, or send_text, which serve different purposes.

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

Usage Guidelines3/5

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

The description implies when to use the tool (when the terminal needs resizing) but provides no explicit exclusions, alternatives, or relationship to other session tools. It doesn't mention when not to use it or what to consider before invoking.

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