toggle_group

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

Only states basic toggle behavior. No mention of side effects, permissions, error cases (e.g., no active window), or state after action. The implementation detail 'Confirmed: hl.dsp.group.toggle()' adds no behavioral value.

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?

Two sentences, efficient but the second sentence ('Confirmed...') is redundant and not user-facing. Could be removed without loss.

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?

With 0 params and no output schema, description should fully specify behavior. It covers the primary action but omits error scenarios and preconditions. Adequate but incomplete.

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?

No parameters; schema coverage 100%. Description adds no extra parameter info, but baseline 4 is appropriate.

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 tool toggles grouping on the active window, with a helpful analogy to i3wm's 'tabbed' container. It distinguishes from siblings like group_cycle and toggle_group_lock.

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?

Implicit usage: to group or ungroup the active window. No explicit when-to-use or exclusions compared to group_cycle or toggle_group_lock.

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