focus_create_tag

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

No annotations are provided, so the description must carry the behavioral burden. It only states 'create a tag immediately,' which reveals the action is immediate but does not disclose side effects, permissions, idempotency, return values, or error conditions. This is insufficient behavioral transparency for a mutation tool.

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 very short and action-oriented, but the prefix 'Toggl Focus/2.0:' is redundant given the tool name starts with 'focus.' Every other word earns its place; a slightly cleaner version would omit the redundant prefix.

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?

For a simple creation tool with a 4-parameter schema and no output schema, the description provides the essential purpose but lacks context about response format, optional parameter defaults, or any side effects. The schema fills in some gaps, making the description minimally adequate but not comprehensive.

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?

The input schema already provides descriptions for color, workspace_id, and organization_id, covering 75% of parameters. The description only restates that name and color are required, which the schema already specifies. No additional semantic value is added beyond the schema, so the baseline 3 applies.

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 action ('create') and the target resource ('a tag'), with a specific verb and object. It also mentions the required inputs (name and color), distinguishing it from sibling tools like focus_list_tags or focus_create_project.

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 the use case (creating a tag) and provides a prerequisite (requires name and color), but it does not provide explicit guidance on when to choose this tool over alternatives or any exclusion criteria. The purpose is self-evident, giving an implied usage context.

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