add_group

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

With no annotations, the description carries full burden. It explains auto-placement and normalization of children, but lacks details on error handling, permissions, id generation format, or side effects on existing buffer. Basic traits are covered but not exhaustively.

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 concise with two paragraphs and bullet-like Args. No unnecessary words, front-loaded with main action, and every sentence adds value. Excellent structure.

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?

Core usage is covered: purpose, parameters, and auto-place behavior. Given an output schema exists, return values are not needed. However, missing guidance on prerequisites (e.g., buffer existence) and explicit when-to-use vs siblings, but still largely complete.

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 coverage is 0%, so the description compensates fully. Each parameter is explained: group_json with an example, tab_index as 'Which tab to add to', and position as 'Optional [row, col]'. This adds critical meaning beyond the raw schema types.

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 clearly states the verb ('Add') and resource ('group container to the buffer'), and distinguishes from siblings like add_control by explaining that it adds a container with nested children. The auto-place behavior further clarifies its purpose.

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?

The description implies usage for grouping controls but does not explicitly state when to use add_group over alternatives like add_control or add_tab. No exclusions or conditions are given, leaving the agent to infer context.

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